For pipe diameters between 8" and 36" (200 mm - 900 mm)
The bigger the pipe, the longer it takes to fill a chamber with gas. Consequently WELD-TECH has developed this cylinder, with a chamber, which is only 3 cm wide.
The time to place PGE Type 150 and filling the chamber with gas, ensuring max. content of oxygen of 25 ppm (0,0025%) is carried out between 5 and 15 minutes, depending on the pipe size.
