Heat Resistant Purging System 16" [ 369 – 394mm]
Available Sizes: 3 to 80” (63 to 2044mm)
Systems for the fast Purging of High Temperature Pipework
The TAG Pipe Purge Bag and Rapid Purge Systems are both available as heat resistant versions.
Designed for use when high temperatures will be encountered during the process of pipe welding; such as pre-heated pipework, and pipes where very high temperatures are required for welding.
These versions of our inflatable Pipe purging systems are heat resistant up to 350ºC (572ºF) for up to 24 hours, or up to 500ºC for short periods of
time, as with the standard systems, the heat resistant systems are available for all pipe diameters from 3 to 80" (75 to 2035mm).
Mirroring the features of the standard range of inflatable purging systems, the heat resistant range comes with a central band for rapid centering of the system to the weld root for the fastest set up times.
The welder can position these systems prior to pre-heating and leave them in place throughout the pre-heating, welding and post-heat treatment cycles, allowing the weld to be purged continuously for up to 24 hours if necessary.
Heat resistant up to 350ºC (572ºF) for up to 24 hours, or up to 500ºC for short periods
Available for all pipe diameters from 3 to 80" (63 to 2044mm)
Designed to be flexible, for ease of insertion, use and withdrawal from pipes, bends, elbows etc. Suitable for 24 hour cycles including pre-heat, welding and post-weld heat treatment
A central strip allows fast and accurate alignment of the system to the centre-point of the weld area
Manufactured to Nuclear Quality Standards with nuclear approved materials, these systems guarantee bright, shiny, coke and oxide-free welds
Designed and manufactured specifically for the power industry where high strength chrome alloy steels are more frequently used
Ready to use, connects to a dedicated and regulated gas supply. Choose any flow rate (Purge Bags – up to 20l/min/Rapid Purge up to 80l/min) through the twin pre-set purge valve
How it works
Both the Heat Resistant TAG Pipe Purge System and the Heat Resistant Rapid Purge™ System work identically to the standard systems, but are made using a purposely designed Nomex and Kevlar mix material to withstand the temperatures typically encountered when welding exotic materials.
A carriage charge is applied to orders, for standard 1-2 day shipments to mainland destinations within the United Kingdom. Other destinations and premium services are available but subject to additional freight charges.
