Purging Equipments

SC Profi  Flange-Cone is designed for the welding of fl anges, 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 and in a special design. The construction of the gas diffuser guarantees a laminar fl ow of gas without turbulence during purging and the welding process. Gas fl ow* 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. SC Profi  disc in the special design is available in the same dimensions as the SC Profi  discs. For larger dimensions please ask.

This assembly is designed for welding vessels fi tted with an inspection chamber and in the stated range of sizes. The vessel must be placed on turning rolls, and the legs on the column are adjustable so that the tool can be used for more than one size of vessel. The gas drag is held between the 11 o’clock and 1 o’clock positions by a balance weight when the vessel turns. The setting-up time is about 5-10 minutes, and the tool can be dismantled and removed through inspection chambers of 350 mm φ or more. The vessel must be circular ± 30 mm and suitable for TIGwelding. There is a special Schnorrer water-cooled gas-drag for plasma welding.
