Welding purge plugs available in a variety of sizes to fit a range of tube or pipe sizes from 10mm up to 100mm in diameter.  Made of a strong heat resistant silicon material, these purge bungs are heat resistant to 340°C, perfect for professional purging of tubes or pipe when welding.

Made by Danish company Walter Schnorrer specialising in purging equipment, these purge plugs allow you to bung either end of the pipe or tube being welded, to purge the inside with a shielding gas for perfect welds every time.

By back purging, the shielding gas protects the inside of the welded joint to prevent oxidisation.  This is particularly desirable when welding stainless and titanium pipe, to achieve optimal results.

Block the end of the pipe with the purge plug and feed the gas through the hole in the centre of the plug using the gas finger outlet. The sintered metal gas finger disperses the gas with a laminar flow to prevent turbulence.


Why Purge

When welding, a shielding gas is used to protect the molten weld pool from the atmosphere.  Contamination from atmospherics can lead to decreased weld strength and decreased anti corrosive properties within the solidified weld.  By creating an oxygen-free environment on both sides of the weld, prevents oxidation, maintains the inherent properties of the parent material, and ensures the longevity and reliability of welded components. Furthermore, effective shielding ensures that the welded joint retains its corrosion-resistant properties, making it suitable for applications where maintaining hygiene and preventing contamination is critical.
