Repair couplings

Repair couplings (clamps) can be used in the repair of pipeline systems caused by various defects in pipes: cracks, needle holes, through corrosion, damage from welding, fractures of pipes, heating networks, sewage systems, water supply and irrigation, as well as systems that ensure the operation of industries, industrial complexes, buildings and structures.

Installation of repair couplings NSK allows you to eliminate the leak without dismantling the pipeline, repairs can be carried out under pressure.

Repair couplings (clamps) are designed for:

  • tight connection of pipes intended for the transportation of liquids, gases, solid bulk products.
  • applications in thermal, nuclear, hydroelectric power plants, oil and gas production, oil and gas processing, petrochemical, chemical, pulp and paper and other industries for the needs of the national economy, for example, in water treatment.
  • operation in all macroclimatic regions on land, including those with a cold climate (general climatic version HL) at an ambient temperature from minus 40 ° C to plus 45 ° C in accordance with GOST 15150.
  • can be installed on pipes made of steel, cast iron, asbestos cement, steel coated with polyethylene, polyvinyl chloride, reinforced fiberglass and polyethylene with diameters from 48 to 609 mm.
