AQUATHERM BLUE Welding techniques

Due to their exceptionally good welding properties, pipe and fitting fuse to form a homogeneous, materially bonded unit. For this purpose, the pipe and fitting are briefly heated with the aid of tools provided for this purpose and then simply joined together; that's it! Double material thickness at the joint - this means double safety at the otherwise critical point of a piping system.

Welding Parameters

Heated Tool Socket Welding

The fusion is subject to the following data. The General Guidelines for Heated Tool Socket Welding acc. to DVS 2207 Part 11 are applied hereupon.
