WS Plus Cylinder

8-40″ ID

8-40″ ID

For pipes from 8″ to 40″ the WS Plus purge gas cylinder is available. This tool is developed with double heat resistant sealing lips. The WS Plus purge gas cylinder is heat resistant up to 340ºC (max 1 hour). The tool has an extremely short purge time only 2½ minutes for all dimensions, which no other purge tool can provide.

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

The difference between WS og WS Plus is the design, the material (heat resistance) and the price. By changing the lips e.g. the sealing lips on a 10 WS can be supplied with a 12”, it is possible to weld three different tube diameters with the same cylinder. The WS Plus has longer sealings. This secures, that the tool always is tight, also in situations where bends are welded.

Custom made sizes available upon request. Contact Walter Schnorrer ApS for more info.

The WS Plus purge gas cylinder is suitable for Offshore, and when mounted with a pull system (extra equipment)  it goes through several bends without any problems.

When pulling the WS Plus through elbows, the pull wire will always place itself at the inner side of the bend, risking the cylinder getting stuck. For this reason, a console or pull ball is recommended if you have to pull the WS Plus cylinder through any elbows. In case of serval elbows or serval uses of the WS Plus cylinder in a single day, using both a console and pull ball will save noticable amounts of time and effort.

For the best experience, using a console, pull ball and non-isolated pull wire (1715000) is recommended. This centers the pull wire through elbows, and eliminates risk of friction.
