Inflatable Pipe Purging Systems
USING PROVISIONAL DAM SYSTEMS
Provisional Dam Systems
2
■ Time consuming to fabricate
■ Full of voids, gas and water vapour
■ Made with high vapour pressure materials
May leak and allow harmful gases back into the welding environment
ARGWELD® RANGE
Uses less inert gas Uses up to 90% less gas of that required for conventional purge
Faster Quick and easy to install, dams inflate instantly, purging time is fraction of time required for conventional methods
Improved weld quality Leading to bright, shiny, coke and oxide-free welds
Fast payback ARGWELD® Inflatable pipe purging systems pay for themselves in just one or two welds
Highest standards Manufactured to nuclear quality with nuclear approved materials
Inflatable Pipe Purging Systems
3ARGWELD® RANGE
ARGWELD® Multi Exhaust Systems
■ Eleven sizes covering all pipe diameters from 2 – 12” ( 50 – 300 mm)
■ An argon hose is connected from the supply to one end of the purge system and gas allowed to flow at a rate of 10 l/m
■ Devices have inflatable latex rubber interior surrounded by protective nylon cover, impregnated with polyurethane to facilitate sliding through pipes■ Dams are connected by a high quality, high temperature resistant rubber tube protected by a metal braid

ARGWELD® RANGE
Argweld® Quick Purge™ Systems
■ Developed specifically for high speed welding of LNG pipework and pipe lines.
■ Also suitable for large pipes, tanks and vessels.
■ Inside is covered with heat protective materials, for protection of the device.
■ Sizes from 8” to 80” (200mm - 20000mm).
■ Very fast weld purge time and a very high quality weld root.
