Pipeline Equipment - Backing Gas Systems

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.

The new patented Purge Gas Equipment EZ-Purge is used from 20mm ID up to 215mm ID.

The unique design of the Silicone Ball ensures that the EZ-Purge always makes a perfect
seal. It is very user friendly and easy to push, pull and position in any Pipe or Fitting.

The Basic Unit comes in two different sizes. The small unit goes from 20mm to 51mm. The
standard length is 140mm but also can be supplied in 250mm. The large unit goes from
52mm to 219mm with a standard length of 180mm and this can also be supplied in 250mm.

Contrary to all other types of Purge Gas Equipment in the world, the special design ensures
that the gas goes through the Basic Unit before it comes out into the Purging Chamber.

This is especially important if welding with a gap, since it helps cool the Basic Unit to
prevent burn/damage from the arc. The Basic Unit can stand up to 450°C.
The Purge time is under 2 minutes for all dimensions.

PGE consists of a basic unit and sealing- and support discs in different sizes,
depending of the pipe dimensions to be welded.

The unique design of PGE in combination with the flexible sealing discs
makes it the perfect choice in the workshop as well as on site. Use the PGE for the welding of pipe to pipe, pipe to bend or pipe to flange.

Going from welding of one pipe dimension to another, you simply change the sealing- and
support discs on the basic unit. This is easily and quickly achieved by using a spanner. To
choose the correct discs for various pipe dimensions, please refer to the chart below.

The PGE can be pulled through bends and the sealing discs are resistant to temperatures
up to 320 degrees Celsius.
