Jointing Techniques

PP-r is highly suited to welding techniques, providing a 100% leak free joint with no interface material.

KAI PP-r Pressure Pipes can be joined by "Butt welding" or "Socket welding"

Butt welding

Butt welding (or butt fusion) is a simple and quick method to connect pipes with fittings or pipe to pipes. The process starts by:

  • Securely fasten the components to be jointed
  • Face the pipes ends
  • Align the pipe profiles
  • Melt the pipe interfaces
  • Join the two profiles together
  • Hold under pressure
  • This will form a welded joint that is water tight and homogeneous.

SOCKET WELDING

This technique consists of simultaneously heating both the external surfaces of the pipe and the internal surface of the socket fitting until the material reaches fusion temperature. The process starts by:

  • Square and prepare the pipe ends
  • Heat the parts
  • Joint the parts
  • Allow to cool
