Description
The Walter Schnorrer and WS Plus Gas Cylinders are available for pipes from 145 mm to 1000 mm diameter. These tools have two heat-resistant sealing lips, with the WS Purge Gas Cylinder being heat-resistant to 280ºC for up to one hour, and the WS Plus Gas Cylinder taking 340ºC for up to one hour. The tools have extremely short purge times of only 2.5 minutes for all dimensions, a feature that no other purge tools provide.
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 WS Plus Purge Gas Cylinder is suitable for critical applications in the offshore industry and, if mounted with an optional pull system, goes through several bends without any problems.
The difference between the WS and the WS Plus is in the design and heat-resistant 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 product difference is illustrated in the photograph, which shows the WS Plus (black seals) with deeper sealing lips. This ensures that the tool is always tight to the pipe wall, including those applications where bends are encountered.
