13-215 mm ID

The Schnorrer SC Profi range of purge tools is for use in tubes and pipes of internal diameters from 13 mm to 215 mm. The SC Profi is supplied as a complete unit, so there are no loose pieces to “disappear” or be lost. The SC Profi gas cylinder consists only of two triple-sealing lip elements, a gas inlet and a gas outlet, a connecting axis and a connection hose with a rectus nipple. There are three different kinds of connecting axis; a solid connection is used for straight pipes, a flexible connection for elbows, and a spring connection for when the tool needs to go through several elbows, one after the other. As standard, the SC Profi models 17-45 mm are supplied with a spring connection for use in the relatively sharp elbows met in these pipe sizes, while all other SC Profi models are delivered with a flexible connection. The gas inlet and outlet are provided with triple sealing lips that prevent them from tilting or falling over inside an elbow, and the design also guarantees that at least one lip will always remain tight to the pipe wall. These tools are made with three sealing lip elements that ensure an effective gas purge even when pulling an SC Profi through pipe elbows. The standard purge tool is supplied with a flexible connection, but it can be advantageous to fit the tool with a spring connection. The advantage of this spring connection is that it adapts exactly to the bore of the pipe, a feature that is particularly useful in tubes below 2½” bore, where you often meet relatively sharp elbows. The discs are UV- and temperature-resistant up to 340°C for up to one hour. The gas diffuser is made of sintered metal to ensure long life and is integrated into the inlet disc. This design of gas diffuser provides an even flow of gas and prevents any gas turbulence behind the weld, thereby minimising the risk of oxygen in the welding chamber while, at the same time, achieving an extremely short purge time. These extremely short purge times result in valuable cost savings in gas and time and the weld seams are without temperature discoloration. The flowrate is 10% of the internal pipe diameter, and 20% if welding titanium
