PIPE Ltd is a manufacturer and supplier of pipework
manufacturing equipment. Its comprehensive range includes
pipe bevelling machines, pipe cutting machines, pipe welding
alignment clamps and pipe jack stands. With its extensive
knowledge in this field, the company has progressed into the
manufacture of dedicated purging systems and accessories to
enable high quality welding of exotic materials.
Having seen the problems faced by pipe welders when
required to weld exotic materials, Pipe Ltd now manufactures a
range of weld-purging systems to remove oxygen from the weld
chamber as quickly as possible, allowing the welder to produce
high quality, oxide-free welds.
The latest addition to this range is the patented ‘Rapid Purge’
system. Utilising a ‘donut’ design twin inflatable bladder housed
in a special Nomex and Kevlar mix heat-resistant material, the
‘donut’ and ‘thru-bore’ design of the system means that the area
to purge is localised to the weld root, reducing both gas usage
and purging times. For example, a 36" pipe will purge down to
0.1 per cent oxygen in less than 10 minutes.
Whether 8" or 80" pipe, due to the materials used these
lightweight yet rugged systems allow easy withdrawal from
the pipe once deflated, even round bends and elbows. Used in
conjunction with PIPE’s range of weld purge monitors, the systems
enable the welder to produce high quality welds in very little time
and with no oxidisation.
