Instruments

Most of us understand that there is nothing perpetual, so emergency situations may arise during the operation of pipelines. This also applies to heating systems, water supply, and gas supply, when repair is required immediately. Otherwise, the consequences could be much more serious.

Through the use of special tools, it is possible to repair networks without shutting them down. Typically, for such purposes, use repair clamp on the pipe, a simple, and at the same time effective element.

Who makes it

Our market of sanitary products is filled with products of foreign and domestic manufacturers. You can even meet all well-known trademarks and global brands.

Many will confirm the high quality of manufacturers from such countries:

  • Switzerland;
  • Israel;
  • Holland - the company Romacon;
  • Germany represented by Melcher + Frenzen Armaturen;
  • China - IDRA;
  • Poland - Domex;
  • Denmark - AVK;
  • Russia - Ecovod.

Eats and other companies, but they all share one thing - compliance with European standards and certification for use in the territory of the Russian Federation. Products are offered in a wide range, which allows it to be used on pipelines of different diameters and with different working media, for example, for drinking water supply networks.

Reliable and durable repair clamps for water pipes

Purpose of products

The design of the clamp allows you to urgently make an inexpensive repair of pipes from such materials:

  • cast iron;
  • become (stainless or galvanized);
  • polyethylene;
  • metal plastic;
  • asbestos cement.

What connections you can repair:

  • post weld damage;
  • longitudinal cracks;
  • pipe fracture;
  • needle holes;
  • shock damage;
  • corrosive fistula.

Two-part clamps

These are the simplest models offered by various manufacturers to consumers.

Their design includes:

  • 2 steel (galvanized, stainless steel) half rings;
  • bolt for their interconnection in the damaged area;
  • gaskets.

The instruction is simple - you apply a repair clamp to the damaged part of the pipeline and firmly bolt two half rings with a bolt.

Internal seal - cuff, made of nitrile or cellular corrugated rubber. So you can achieve tightness of the damaged area.

Tip: the use of such products is possible only for pipes of the same diameter.

Benefits
  1. Simplicity and speed of installation. At the same time you do not need a special narrow-profile tool - just a wrench.
  2. The speed of the sealing work at the site of damage.
  3. Competitive price of repair material.
  4. Reducing the cost of repairs.
  5. The process can be carried out without disconnecting the site from the overall system as a whole.
  6. Durability and high reliability of connection.

Usually, elements of the repair clamp are most often made of passivated stainless steel, so there is no need for additional steps to protect it from corrosion.
Terms of Use
  1. The outer diameter of the pipe must be less than the length of the product.
  2. When repairing pipes O350 mm, the length of the repair clamp should be 150 mm longer than the damage.
  3. For overall pipelines, the dimensions of the product must overlap the damage dimensions by 200 mm.
  4. When repairing PVC pipes, the length of the clamp must be 1.5 times longer.
  5. In case of fracture or docking, the pipe ends should be at a distance of no more than 10 mm from each other, the deviation angle should be up to 2-3?
  6. The clamp can normally perform the task with a maximum damage value of 60% of the covered surface.

Kinds

The item has several types of working designs. (See also the article How to eliminate pipe leaks: features.)

For example, the material may be:

  • non-corrosive steel;
  • galvanized steel;
  • stainless steel;
  • cast iron.

Mount Type:

  • unilateral;
  • double sided;
  • standard;
  • two-part standard;
  • threefold (for pipelines of large diameter).

Tip: for large pipe diameters, manufacturers offer composite structures consisting of a different number of fragments, the number of which depends on the diameter value.

Product Feature

  1. The compression part (bandage) is made of stainless or galvanized steel with a thickness of 1-2 mm. Carbon steel 20 (1.5-3 mm) can also be used for stamped clamps. Sometimes - cast iron.
  2. The seal (cuff) is made of cellular, corrugated rubber.
  3. Fastener parts are made of galvanized or stainless steel.
  4. Working pressure is 6-10 ATM.
  5. Working environment - inert gases, water, air.
  6. The maximum temperature is 110-120 ?.
  7. Temperature range of operation is -20 + 60? ะก.
  8. The diameter of the product is 15-1200 mm.

Double-sided stamped clamp of steel 20 is used for the repair of plumbing.

The kit includes:

  • a pair of stamped galvanized or steel half couplings with stiffeners;
  • rubber gasket;
  • Stainless or galvanized connecting bolts with nuts and washers.

The diameter of the product is 15-600 mm. One-sided stainless steel clamp or rolled tube coupling, thickness up to 1 mm. It is made in the form of a ribbon-shell, the edges of which are interconnected by tubes and fasteners of galvanized steel.

Sealer - has a cellular surface, so it is possible to create a tight connection. DU - 15-1000 mm.

Conclusion

The use of these products in the planned and emergency repair of pipelines of different diameters is cost-effective and reliable. It is possible for many years to be a fairly simple way to ensure the smooth operation of the system. The video in this article will help you find additional information on this topic.
