1. The rubber is pressed tightly against the defect on the pipe and does not allow water to flow out of the pipe; the more uneven the surface of the pipe, the thicker the rubber should be.
2. To hold the rubber tightly on the pipe, you need tin - this is the frame of the clamp; the more uneven the surface of the pipe and the denser the rubber, the thicker the tin should be.
3. The bolts tightly tighten the tin frame and provide the necessary tightness of the rubber to the pipe. The more uneven the surface of the pipe, the denser the rubber, and the thicker the tin, the larger the diameter of the bolts. The thicker and softer the rubber, the longer the bolts will be needed.

The clamp looks like this:

The sequence of making the clamp is as follows:

1. Determine the diameter of the pipe using a caliper (or an angle and a ruler for large pipe diameters).
2. Cut the tin frame of the clamp 4-8 cm wide and long equal to length pipe circumference + 3-4 cm for ears. The larger the diameter of the pipe, the wider the clamp is made. The circumference of the pipe is equal to the diameter multiplied by the number P= 3.14. Marking can be done with a marker, a children's felt-tip pen, and even a sharp screwdriver if there is no special “scriber”.
3. Mark and drill holes for the fastening bolts on the ears; the more accurately you do this, the easier it will be to install the clamp. If you use wide washers, you can drill holes 2-3 mm larger than the diameter of the bolts, this will simplify installation of the clamp. For clamps wider than 6 cm, it is advisable to drill holes for 3 bolts.
4. Mark the ears and bend them 90°, holding a piece of tin in a vice or using pliers.
5. Bend the tin around the pipe on which you will put the clamp, so that the ears connect and the drilled holes match. If necessary, tap the tin with a hammer, but usually this is not required.
6. Cut a rubber gasket with a width equal to the width of the clamp and a length equal to the circumference of the pipe - 0.5-1 cm.
7. Insert the rubber gasket into the clamp.

The clamp installation sequence is as follows:

1. Spread the ears of the clamp so that the clamp can be placed on the pipe.
2. Place the clamp on the pipe so that the rubber gasket covers the pipe defect well. Ideally, the pipe defect should be located in the center of the rubber gasket. If you did everything correctly, then there will be a distance of 1 - 3 cm between the ears. When tightened with bolts, it will decrease
3. Insert the bolts with washers and wrenches or a wrench and pliers and tighten the bolts so as to press the rubber gasket against the pipe as much as possible.

Almost always, clamps are placed on a leaking pipe without shutting off the water supply or Wastewater, so you can immediately evaluate the quality of the clamp installation. Wipe the clamp and pipe dry and wait 5-10 minutes; if water does not ooze from under the clamp, then everything is fine.

The clamp can stand for years and even decades, but still better pipe, especially plumbing or heating, brew.

If, when installing the clamp, you used too long bolts and they irritate you or your wife with their sharp appearance, they can be cut with a hacksaw or grinder.

Fastening by installing a clamp is one of the most affordable and at the same time inexpensive ways fixing the pipe to the structure or support. With their help, it is easiest to achieve a strong and reliable fixation of the pipeline. To choose the right device, you need to know what options the market offers. Do you agree?

We will tell you what you should pay attention to when choosing pipe clamps. The article we presented describes in detail how to choose best option and how to install it. The technology is described in detail and recommendations are given, adherence to which will ensure an ideal result.

According to the principle of fixation, the pipeline can be attached to the support either rigidly or freely.

The rigid rigid mount is designed for maximum loads. It is chosen when installing “cold” pipelines and strengthening them in places where there is a high risk of structural damage.

The floating type of fixation is used in sections of the pipe where there is a high probability of expansion of the structure under the influence of temperature fluctuations

To fasten elements subject to thermal expansion, devices with floating mounts are chosen. They give the structure minimal mobility in the axis direction.

Fixing the pipeline with a clamp is achieved by tightening the pipe body with fasteners, the role of which is performed by locks, threaded pairs or worm mechanisms.

Regardless of the type of fixation, the use of clamps makes it possible to relieve the pipeline, thereby reducing the likelihood of damage to its individual sections under the weight of its own weight and vibration flows arising during movement.

Video guide on using a clamp as a repair element:

By choosing a holder wisely and attaching the clamp to the pipe in accordance with technical standards, you can ensure the strength and reliability of fixing long and unstable sections of the pipeline.

If you have ever secured pipes using clamps, share your experience with site visitors. It is possible that you know technological subtleties, not mentioned in the article. Please write comments in the block below, post photos on the topic and posts with your opinion, and ask questions.

At the first signs of depressurization of the pipeline, it is necessary to quickly find the damaged area and eliminate the identified defect. When performing emergency emergency work, you can use homemade clamps to stop the flow in the pipeline for a while. Ready-made clamps for fastening pipes, produced in the factory from of stainless steel or fire-resistant plastic, used when performing installation work on heating, sewerage, water supply, and gas supply systems. These fasteners allow you to reliably fix the position of pipes running along horizontal and vertical surfaces(ceilings, walls), as well as those installed on special racks.

In this video experienced master shows how to make a wire clamp:

Design of a simple clamp

Without exception, all pipe clamps consist of a bandage - a crimping material made by manufacturers from steel, and an internal seal called a cuff. As a sealing material that ensures sealing of the damaged area, special corrugated rubber is usually used, which helps prevent deformation of the pipe when the fastening screws are tightly tightened. The presence of a rubber gasket in the design of the product also helps reduce vibration and noise.

When choosing clamps, pay attention to such product characteristics as:

• inner diameter;
• bandage width;
• thickness of the steel strip.

The tightening range of the clamp varies depending on the size of the fastener. The main indicators that determine the scope of its application are the strength of the connection and the level of permissible load.

Metal clamps for fastening and repairing pipes of different diameters consist of steel frame and a seal made of corrugated rubber

Making a clamp from scrap materials

Find a strip of galvanized sheet metal, the thickness of which does not exceed one millimeter, and a piece of three-millimeter rubber. Look in your supplies for a couple of bolts (M6, M8 or M10), as well as matching nuts and washers. Tools that will be useful:

• hammer;
• calipers;
• spanners;
• vice or pliers;
• metal scissors, which can be replaced, if available, with a jigsaw or grinder equipped with appropriate cutting elements;
• drill and drill bits (M7, M9 or M10, M12).

Use a caliper to determine the pipe diameter. If the pipe diameter is large, then take the necessary measurements using an angle and a ruler. Next, cut out the tin frame of the clamp in the form of a strip, the width of which should be 4-8 cm, and the length will have to be calculated. To do this, determine the circumference of the pipe by multiplying its diameter by 3.14 (the number Pi, familiar to everyone with school course geometry). Add 3-4 cm to the result obtained, from which “ears” are subsequently made with drilled holes for fastening bolts.

The size of the holes in the “ears” depends on the diameter of the bolts, and if the washers are wide, then you can add an extra 2-3 mm to simplify the installation of the clamp in the future. If the width of the bandage exceeds 6 cm, then it is recommended to drill holes not for two bolts, but for three. Mark with a marker a line along which to bend the “ears” at a right angle to the tin strip. This operation can be done manually if the strip is thin. Thicker material is worked with a vice or pliers.

Next, the tin is bent around the pipe on which it is planned to put the clamp, and they try to connect the ears so that the holes drilled in them coincide. If the tin does not bend well, then tap the strip with a hammer. A pre-cut rubber gasket, cut to fit the width of the bandage, is inserted into the clamp.

Algorithm for installing a clamp on a pipe

Before installing the clamp, the ears are moved apart so that they can easily wrap around the pipe. In this case, the rubber gasket should well cover the area of ​​the pipe defect. If everything was measured correctly, then there should be no more than three centimeters between the ears. This distance will certainly decrease in the process of tightening the clamp with bolts, and this process continues until it is possible to press rubber compressor to the pipe as tightly as possible.

Clamp for eliminating leaks in a water pipe or heating system At home, it can be installed at the site of damage with your own hands within a few minutes.

In most cases, clamps are installed on a leaking pipe. The supply of water, coolant or wastewater is not shut off. Therefore, the effectiveness of the repairs performed will be immediately visible. After wiping the pipe and bandage dry, wait about five minutes and make sure that the leak has been fixed. If necessary, bolts that are too long can be easily cut with a grinder or a hacksaw.

A properly installed clamp can last for several years, protecting the facility from flooding. However, it is advisable to weld breaks in water supply and heating systems or replace defective areas with new pipes.

Insertion into the main water supply

When connecting the water supply of a private house to central system For water supply, a mortise pipe clamp is used, which allows work to be carried out under pressure in a short time using specialized professional equipment. A clamp for tapping into a pipe without pressure is installed by a simple mechanic using a cutter and a pair wrenches. It is not intended to use welding machine. In any case, this work is carried out by employees of services servicing the main water supply system in locality, provided the client has all permits.

Stages of installing a mortise pipe clamp in a main pipeline. Clamps for inserting into pipes simplify work on connecting the facility to central water supply systems

Now you know how to make and install a clamp on a water pipe. If the pipeline is damaged, you will be able to fix the problem yourself, at least for a while before professional plumbers arrive.

Every man has encountered the connection between a hose and a water pipe or tap. This is usually a simple procedure: fit the hose tightly onto the pipe and turn on the water. But such a connection often leaks water, and the hose itself sometimes falls off. Then a wire clamp comes to our aid, which can help out in a difficult situation.

First of all, I would like to clearly define the concepts: what can actually be called clamps. So, this is a ring-shaped device, usually made of light metal alloys. It has a tightening mechanism in the form of a special nut, mainly with a worm thread, and also, depending on the models, a metric thread is used on the nut. In our case, the base of the device has a wire base, but is made of a fairly strong metal that does not deform when pulled together.

IN modern version the tightening element is just the nut with metric thread, when twisted, the mechanism tightly fits the surface, while thoroughly clamping it onto the working base. The scope of application of clamps is quite wide, but the range of action is designed to create a hermetically sealed connection of hoses, rubber pipes with solid bases, and pipes. Using a clamp, you can tightly connect the water pipeline with a rubber hose and not be afraid that there may be a leak somewhere.

Even corrugated pipe for exhaust, it is attached to the chimney using a clamp and does not allow combustion products to enter the room.

Initially, such a device was created not for domestic needs, but for the automotive industry. Clamps are an important element in the engine of almost any car. Ask why? The fact is that the engine of the machine during operation, due to vibration, is in a moving state, and various connections, fuel and oil supply are different pipes. It is the rubber pipes that have free movement and vibrate evenly along with the engine, while fulfilling their duties of supplying fuel. Well, they are attached to a metal base with clamps; they are able to provide a reliable, sealed, and most importantly, durable connection of important engine components.

Among such fastenings, I would especially like to highlight one type of product: spring wire clamps, which work on the principle of clothespins; such fastenings fully correspond to their specifics. This technology and allows you to install them for their intended purpose without using additional tool. The design of such a device is a thickened elastic wire, and it is quite rigid, which allows it to maintain a given diameter. There are two “ears” at the edges, which act as “clothespins”.

In order to install such a clamp at the place of use, it is enough to squeeze the “ears” with your fingers, and the diameter of the clamp will increase, after which it can be put on the pipe. That's the whole process of installing such a universal clamp. It is possible that skeptics may doubt that such a simple device can create a tight, airtight connection. But we can assure you that the connection is quite strong and reliable, these arguments directly confirm the laws of physics. The thing is that such devices are designed for use in places with temperature changes.

In a normal environment, the fastening mechanism exerts its operating pressure on the connection; when heated, the metal begins to expand, thereby enhancing the clamping property several times. U of this device there is a small one by-effect, usually over time, such a clamp tends to pinch the rubber hose, rendering it unusable. It is not recommended to use such fasteners in a car engine, or you can use it with subsequent replacement.

It’s good when the household has such a fastening element. Of course, such a thing is not necessary every day, but there are times when you simply cannot do without a clamp, especially for car owners. But if you constantly forget to buy such a part for your kit, let's figure out together how to make a wire clamp, having minimum set tools and materials.

To do this, we need the wire itself, which should be soft enough, but at the same time quite strong. The most useful tools are a screwdriver and a screwdriver, which can be found in almost any home. Now let's look at the whole process step by step, which, as you guessed, if there are a minimum of elements, it will be quite simple.

How to make a wire clamp - step by step diagram

Step 1: Measure the required wire length

First of all, let's cut off as many wires as the diameter of our connection requires. Measuring instruments we don’t need it, just wrap the edge of the wire around the pipe and estimate the ends for twisting by eye, usually 50-60 millimeters is enough. Then fold the wire in half and use pliers to bite off the excess. We bring the ends together so that they are on the same level.

Step 2: Correct clamp arrangement

Now that you have a wire bent in half in your hands, you need to make the correct “eye” at the bend, and the diameter of the “ear” should coincide with the screwdriver, which should fit freely into it. To maintain this size, just straighten the ends, insert a screwdriver between them and bring them together again. Of course, it is best suited for such purposes; it is even along its entire length and does not have an expansion, unlike a flat one. Next, you need to bend the resulting “ear” to the side, relative to the length of the wire, it will serve as a lock.

Step 3: Detailed installation of a homemade clamp

You’ve just made a wire clamp with your own hands, it’s okay if it looks unsightly, the main thing is that it performs its functions efficiently. All that remains is to install it in its place of honor and twist it tightly. To do this, bend it around the pipe, always in the form in which it is, namely twice, and cross the ends together. Then we insert a screwdriver into the “ear,” hook the other end and turn it clockwise several times until a tight connection appears. Remember that when clamping you should not be too zealous, you should feel when to stop so that the wire does not break. If there is too much left on the newly installed clamp long ends, we recommend biting them off with wire cutters.

It is possible that the first time you will not be able to install a wire clamp made by yourself, perhaps you will not get the twist, or you will overtighten it, but do not despair, repeat the procedure for making the fastener again. We are confident that after several attempts you will get a high-quality and tight connection, and this simple technology will always help you out Hard time. Patience and a little effort! But still, for the future, keep several clamps of different diameters in your household, they will definitely come in handy!

People who at least sometimes do repairs and installation work They know that a clamp may be needed at the most unexpected moment. This is the first device that comes to mind when you need to quickly fix a pipe leak. Indeed, applying a clamp is a temporary measure, but sometimes necessary. It is possible that, due to circumstances, it cannot be purchased right now; besides, even a simple wire clamp will do to solve the problem. Therefore, you need to do it yourself.

Pipe leak

Design features of the product

Clamp - simple and effective adaptation, which has a lot of standard variations, but, in fact, they all have similar structural characteristics. The difference is presented in the form of shapes and fastening devices. Their use is most common in the field of installation and repair of pipeline systems, this leads to another characteristic feature designs. For better fixation and tightness, the product often has a rubber gasket.

Regarding the practical benefits of the products in question, we can say that without them it is almost impossible to carry out high-quality fixation of the pipeline, both horizontal and vertical.

The line of types of this device begins with the simplest one-sided products, which are a threaded pin. It then continues with variations that differ not only in the greater complexity of the design, but also in size (this should be understood as the maximum diameter of the pipe for which a particular product can be used) and intended purpose.

The most common problems that clamps help solve:

• Repairing cracks in pipeline systems. Depending on the type of product, even fairly large damage can be covered.
• Pipe fracture is not a common but serious problem. For the most part, it is encountered by those who professionally install and repair pipelines.
• Also, if it is necessary to eliminate “fistulas” water pipes, again clamps are widely used. In such a situation, it is necessary to use a soft substrate.

Note! If the pipe being repaired is used to transport corrosive liquids, then it is necessary to use a type of fastener that can withstand these specific operating conditions.

• Specifically for steel pipes, the product can help reduce the risk of leaks caused by corrosion. Situations often arise where it damages the metal so much that a leak can occur at any minute.

The market is saturated with all sorts of clamp configurations different manufacturers. Factory production, in addition to professional manufacturing, also provides a guarantee of quality. After all, the products are manufactured in accordance with GOST. Such government quality regulation is associated with the high degree of role of clamps in maintaining the integrity of the structures in which they are used. Based on this, the question arises whether it is worth making a clamp on steel pipe with your own hands.

Is it worth making clamps yourself, and what mistakes can be made?

The clamp is, at first glance, a simple device that does not differ in any characteristics that are difficult to understand. The presence of risk associated with the manufacture of homemade clamps depends on how confident the person is in his abilities, and whether the clamp can be used in the given conditions.

For example, a fairly rusty heating pipe leaked. The area of ​​corrosion in the damaged area has a fairly wide area. If the clamp is made incorrectly, the required size, then after trying to install it, the situation can only get worse.

Based on this, naturally, it is better to always have factory-made clamps of various modifications and sizes on hand, or if problems arise with the pipeline, immediately contact the repair service. Unfortunately, neither the first nor the second options are often feasible. No one plans for a leak, the time of its occurrence is not regulated, and it is not possible to have clamps of all configurations available.

If a leak occurs, immediate action must be taken. And it is for this purpose that you can make a clamp with your own hands, which will give you time to solve the problem in full.

The simplest clamp

With absence specialized tools and materials such as grinders, drills, sheet metal and the like, you can resort to the simplest, but for a while problem solver Another option is to make a clamp from a piece of wire. It will help you eliminate the leak as quickly as possible and calmly wait for the help of specialists:

• The first thing to do is find some tape or insulating tape, a piece of wire soft enough to bend, but strong, and a piece of rubber (for example, a tourniquet).
• Next, you should place a piece of rubber on the pipe in the place where the leak occurred, after which it is pressed as tightly as possible with the wire by winding it.

Important! When winding with wire, special attention should be paid to the edges of the future clamp.

• The resulting patch, for greater reliability, is tightly wrapped with adhesive tape (duct tape or tape).

Such a handmade product will not require much time and will help to avoid possible big problems.

Semi-professional option

The previously described example of manufacturing a wire clamp is “urgent”. But if the manufacture of the product does not require much haste, and you have the tools available, then you can build a fairly good version of the product yourself. This one can last for many years.

Necessary tool

First, you need to understand what tool you will need:

• Hammer or light sledgehammer;
• Drill and drill bit (Ø 6 - 8 mm);
• Grinder or special scissors for cutting metal;
• Measuring instruments – ruler, caliper;
• Wrenches, pliers.

Materials

To make a clamp capable of carrying significant loads you will need:

• A metal plate of moderate thickness, preferably up to 1 mm. You should not use steel of greater thickness, since it will not only be problematic to bend, but it will also not allow you to make a sufficiently tight connection;
• Rubber strip, its thickness should be about 3 mm;
• Bolts, nuts (Ø 6 - 8 mm). It is advisable to have washers for them.

Manufacturing algorithm

To successfully make a clamp with your own hands, you do not need any special abilities in this matter, but some basic skills are still needed. According to the advice of experienced plumbers, work should occur in the following sequence:

• The process begins by measuring the damaged area, then cutting a steel plate of the appropriate size. In the dimensions of the plate, it is necessary to take into account not only the length of the damaged section of the pipe, but also its circumference (after obtaining the size, it is worth adding 5 cm to it).

• On both sides of the workpiece, using pliers, the “ears” of the future fastener are bent (eventually they should be perpendicular to the main part of the metal strip).
• In the “ears” you need to drill holes for the mounting bolt.

• Next, a strip of rubber is cut out, the width of which should be less than the circumference of the damaged pipe.

Please note! If the clamp being manufactured has small size(no more than 6 cm), then the “ears” can have one hole in the center for a mounting bolt. If it is larger, then it is preferable to make them more than 2-3.

Installation

Once the product is almost ready, you can proceed to its installation, which will complete the work.

• The metal plate, with moderate pressure, bends around a pipe having a similar diameter to the one that has damaged integrity. Ultimately, the ears should match.
• Attention! If the bend is made unevenly, problems may arise with installing the mounting bolt.
• A pre-prepared piece of rubber is applied to the leak site, after which a steel plate is installed on top of it. Before you begin installation metal element, it needs to be bent a little. This is done in order to simplify the installation process on the pipe.
• And so, if everything was done correctly, then there will be a distance of a couple of centimeters between the “ears”, and they can be tightened with a bolt. When sufficient pressure of the product is reached on the pipe, the flow will stop.
