Walter Schnorrer SC Profi Flange-Cone is designed for purging when welding flanges, couplings and short pipe lengths.

The tool consists of three parts: an aluminium cone, a gas connection pipe and the well known and proven SC Profi disc with an integrated sintered stainless steel gas diffuser.The construction of the gas diffuser guarantees a laminar flow of gas without turbulence during purging and the welding process. Gas flow rates in litres/minute during purging are 10% of the internal diameter (mm) of the pipe, and typical purging times are less than 1.5 minutes.

A further advantage of the Flange-Cone is that it can be used as an alignment tool to hold the pipe sections together and centre them at the same time.
