New Polyethylene Pipeline Integrity Testing Service Launches in North America

TWI Ltd, February 13, 2017

The Welding Institute (TWI) has partnered with TEAM QUALSPEC – a world-class company providing specialty services related to the maintenance, inspection and construction of mechanical and piping systems – to provide the PolyTest™ service to the North American market. PolyTest is a new field inspection system specifically designed for volumetric non-destructive testing of butt fusion and electrofusion joints in polyethylene (PE) pipes.

It has been used in a wide range of pipeline industries including gas, water, offshore oil, mining and nuclear – since it was developed by TWI, one of the world’s foremost, independent, research and technology organisations – with the support of NYSEARCH, a collaborative RD & D sub-organisation of the Northeast Gas Association.

PolyTest is supported by procedures to enable detection of all types of flaw that can occur in PE pipe joints, including planar flaws, particulate contamination and cold fusions. It is backed up by extensive performance testing to determine the acceptance criteria that should be applied.

The self-contained system is fully portable allowing in-trench inspections, and incorporates a simple scanner to accommodate pipes with outside diameters from 4-40 inches and wall thickness from 0.3-2.5 inches. It can also be adapted for pipes outside these ranges. After the joints have been inspected the system generates the results, providing a permanent record of joint integrity.

PolyTest complies with the requirements of ASTM E3044, ASME BPVC Section III Appendix XXVI and EN 13100-3, giving the end user increased confidence in the integrity of PE joints within their pipelines.
