WS Purge Cylinder

WS Purge cylinder

The WS Gas Cylinder is available for pipes from 145 mm to 1000 mm diameter. This tool has two heat-resistant sealing lips, being heat-resistant to 280°C for up to one hour.

The tool has an extremely short purge time of only 2½ minutes for all dimensions, a feature that no other purge tools provide.

The flowrate is 10% of the internal pipe diameter, and 20% if welding titanium

When welding thin-walled pipes with only few elbows, it is recommended to use the WS Gas Cylinder, fitted with a pull ball if necessary.

The difference between the WS and the WS Plus is in the design and heatresistant material of the sealing lips. By changing the lips, e.g. the sealing lips on a 265 mm WS can be replaced with 12” lips, it is possible to weld three different pipe diameters with the same cylinder.

The two tools overlap each other. The choice of product depends on the particular welding application. Factors to consider are, the internal diameter, the number and geometry of the bends, the distance the tool is to be pulled, the wall thickness, any pre-heat, and etc. Only then can a decision be made.
