Jointing

Easy jointing and welding of bigger pipes

HDPE pipes can be manufactured in various pipe lengths and sizes. 110 mm pipes and pipes smaller than 110 mm are usually supplied coiled. PipeFlo supplies the 125mm - 200mm pipes in straight lengths of 6/9/12 m.

These lenghts of pipe can be welded together on site, using subs and steel flanges, available from PipeFlo or companies within its referal network. 

Other possible methods for the jointing of 125-200mm pipes:

Heating element butt fusion welding (butt fusion) is the process of two pipe-ends brought into contact with a heating element. After the removal of the element, the molten pipe-ends are pressed together - creating a monolithic entity. Heat fusion joining is a leak proof process and the most common joining method of HDPE. The internal bead of butt-fused HDPE piping systems does not influence the flow rate and pressure of the pipe system. This means that you can ignore HDPE fusion beads.

Electro fusion welding (fusion welded) is another HDPE jointing method, where two pipe-ends are fitted and melted into an electro-socket. A heating coil integrated into the electro-socket melts the material surrounding the coils and becomes part of the pipes inserted into the ends of the socket. After cooling, a leak proof joint forms.  Flange joints are also suitable for the transition to other pipe materials and for the integration of accessories into the piping system. 

The weld is as strong as the original pipe - creating a monolithic (single piece) piping solution - ideal for high-pressure applications. HDPE pipes, connected through these methods are therefore one continuous self-restrained piece, which requires less maintenance than other jointing methods.

If you desire consistent superior performance from your pipes, you should keep in mind that the jointing of piping is very important. If the jointing is inadequate – your system will under-perform.
