Pipe purging system handles the heat
Argweld heat resistant pipe purging systems allow welding of high-temperature applications, or in high temperature conditions, providing a cost-efficient time-saving tool for clean and reliable welds.
Argweld heat resistant pipe purging systems from Huntingdon Fusion Techniques allow for the welding of high-temperature applications, or in high temperature conditions, providing a cost-efficient, time-saving tool for clean and reliable welds Argweld heat resistant pipe purging systems are designed for materials whose pipe joints and adjacent areas need to be preheated prior to and after welding in order to avoid cracking

Guide to weld purging
A brand new edition of the "Guide to weld purging" has been published by Huntingdon Fusion Techniques.
Such materials (such as P91, a high-strength and lightweight chrome steel) are used in high-stress, high-pressure applications and must be purged throughout the welding process to prevent coking and the formation of notches.
This system enables fabricators to purge pipes in temperatures of 300C for up to 24h.
The Argweld heat resistant pipe purging system comprises two heavy-duty inflatable dams connected by a flexible argon gas pipe.
The whole system is covered in heat resistant material, while the spinal hose is covered with bonded preformed mineral wool to British Standard specification.
Models are available from 4in upward, with a range of 12mm approximately.
By localising the volume to be purged, fabricators benefit from decreased waiting time and shielding gas costs, while the effective elimination of atmospheric gases ensure smooth and even penetration beads on all pipe joints. Request a free brochure from Huntingdon Fusion Techniques ...
