Socket pipe clamps are pipe fittings used to connect two pipes, and their core structure is:

Socket (Bell) : One end is flared, with an inner diameter larger than the outer diameter of the pipe, a socket used to accommodate another pipe.

Spigot: The other end is a straight tube and can be inserted into a socket.
Sealing assembly: Usually, rubber sealing rings (such as O-rings, wedge-shaped rings) are set inside the socket, and sealing is achieved through the structure of the pipe clamp itself or external clamping force.

Working principle

By using the nested fit of socket and spigot, combined with the extrusion deformation of the sealing ring, rapid connection and sealing of pipelines are achieved without the need for welding or threaded tightening, ensuring high installation efficiency.

Advantages and characteristics

Easy installation: No welding or threaded connection required, saving working hours (more than 50% faster than flange connection).

Reliable sealing performance: The rubber sealing ring can adapt to slight displacement and has strong anti-leakage ability.

Good corrosion resistance: Cast iron/plastic materials are suitable for various media, reducing maintenance costs;

Strong seismic resistance: The flexible structure can absorb the vibration of pipelines and is suitable for scenarios such as high-rise buildings and bridge spans.

Typical applications

Municipal engineering: Urban drainage pipe networks, rainwater pipes (such as cast iron socket pipe clamps with diameters ranging from DN200 to DN1200);

Building water supply and drainage: Bathroom drainage risers, kitchen sewer pipes (PVC socket pipe clamps);

Industrial field: Chemical wastewater treatment pipelines, connection of sedimentation tanks in sewage treatment plants;

Gas engineering: Buried natural gas pipeline (ductile iron socket pipe clamp + anti-corrosion coating).
