Key Features of UPVC Repair Coupling for Water

  • Split clamp design: two half-shells clamp around the pipe.
  • Hot tap repair: can be installed directly on pressurized pipes.
  • Reliable seal: built-in high-elasticity EPDM rubber gasket conforms tightly under bolt pressure.
  • Wide applicability: suitable for UPVC, PE, cast iron, cement, and other pipe materials.

Manufacturing Process of UPVC Repair Coupling for Water

Each has a housing injection molded from UPVC or ductile iron. Rubber gaskets are made by compression molding, and fasteners are galvanized carbon steel or stainless steel.

Critical Process Parameters of UPVC Repair Coupling for Water

Every is checked against these parameters:

  • Matching accuracy between housing inner diameter and pipe outer diameter.
  • Hardness, compression set resistance, and aging resistance of the rubber gaskets.
  • Correlation between bolt tightening torque and seal compression.

Raw Material Characteristics of UPVC Repair Coupling for Water

  • Material Composition: Housing: UPVC, ductile iron, or stainless steel. Gasket: EPDM. Fasteners: galvanized carbon steel or stainless steel.
  • Material Properties: offers high housing strength and pressure resistance, while the gasket resists aging and water with good elasticity.

Typical Applications of UPVC Repair Coupling for Water

  • Emergency leak repair: fixes pipe leaks without shutdown.
