In-line & Flanged WeldLink™ joining of PE lined
water injection pipe
WeldLink™ was an innovation by British Gas for a
method of joining PE lined pipe. QAWT was invited
by British Gas to develop the procedures and
techniques for this patented weld joint. Having
manufactured WeldLinks™ for global customers,
QAWT are now the nominated world-wide
manufacturer for the Licensee. QAWT continue to
develop new and innovative procedures to meet
global customer demand.
WeldLinks™, along with Compression Rings form an
integral part of a jointing system for connecting PE
(Polyethylene) lined Water Injection pipe and are a
are a cost effective alternative solution to Duplex or
Inconel clad pipe for Water Injection Pipelines.
