Butt Welding

Butt-welding is a cost effective and reliable way for PP-R junctions. The welding process is carried out by gradually heating up the two weld ends with a weld plate and then joining them under a specific pressure to get a butt-welding joint. This process is common and technically suitable for each diameter when pre-fabrication is needed or where special large size fittings are required as for diameters 160,200,250.

The instructions to be followed are defined by the following standard DVS 2207, chapter 11.
