For pipe from 145 mm to 1000 mm the WS and WS Plus purge gas cylinder is available. This tool is developed with double heat resistant sealing lips. The WS purge gas cylinder is heat resistant up to 280ºC (max 1 hour) while the WS Plus purge gas cylinder takes up to 340ºC (max. 1 hour). The tools have an extreme short purge time only 2½ minutes for all dimensions, which no other purge tool can provide. By welding in thin-walled pipes with only few elbows, |
it is recommended to use the WS purge gas cylinder if necessary mounted with a pull ball. The WS Plus purge gas cylinder suitable for Offshore, and mounted with a pull system (extra equipment) it goes through several bends without any problems.
The difference between WS og WS Plus is the design, the material (heat resistance) and the price.
|
The difference is shown on the photo. 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, as the photo shows, longer sealings. This secures, that the tool always is tight, also in situations where bends are welded. Please see special section about additional equipment for elbows. |
