Krah Integrated Electrofusion

In recent years, pipe and connections welding by electrofusion has constituted frequently used method in today’s market. Because it’s a simple and safe joint. Krah took this as a sign and to favor current market demands, developed its own electrofusion bell and spigot joining system, which it can be included in every single diameter we manufacture.

This joining method work by introducing the spigot into the bell of the pipe, then inducing an electrical current through the resistance pre-equipped in the bell of the pipe and by raising the temperature and applying pressure, both ends of the pipe will join on a molecular level making the joint last as long as the HDPE will.

 Fundamental advantages of electrofusion joints

· Fast welding

· Reasonably priced electrofusion equipment

· Able to work on narrow spaces

· Large diameter pipes can be electro fused from the inside of the pipe

· Quick and easy assembly using different electrofusion equipment

· Great elongation resistance

· Water tight and permanent joint
