At this Section paper evening, Doug Wylie, TWI’s Team Manager for Non-Destructive Testing (NDT) Product Development will discuss his work on the non-destructive evaluation of welded joints in polyethylene (PE) pipe.

Included in this will be a review of PolyTest™. This is a new field inspection system for volumetric non-destructive testing of electrofusion and butt fusion joints in PE pipes. The equipment has been designed and optimised to provide:
- phased array ultrasonic probes, operating at the optimal frequencies
- a simple and flexible scanner to accommodate pipes with outside diameters from 90-900mm
- membrane water wedges to reduce the electronic steering with the probe elements while still covering the weld fusion zone

The system is supported with procedures to enable detection of all types of flaws that can occur in PE pipe welds including planar flaws, particulate contamination and cold welds. TWI has carried out extensive performance testing to determine the acceptance criteria that should be applied. TWI have also validated the system’s inspection capabilities in joints containing known flaws.

Dinner and refreshments are available from 17:30 with the presentation beginning at 18:00.

Doug Wylie - Team Manager: Non-Destructive Testing (NDT) Product Testing

Following a 23-year career in the RAF, Doug joined TWI in January 2009 as NDT Programme Manager, Training and Examination Services, responsible for the delivery of the non-destructive testing (NDT) training across four venues in the UK. In October 2011, after completion of a BEng (Hons) degree through the Open University, he transferred to the NDT Section.

Doug, an Incorporated Engineer and multi-method NDT Level 2/3, has experience across a variety of industry sectors. He has been involved in NDT application both on and offshore, third-party inspection witnessing, procedure development and review, collaborative projects and single-client project support. As a team manager he is now responsible for developing the delivery of NDT products in TWI’s Integrity Management Group, and is also leading the innovation project ‘PolyTest’, a new system for inspecting butt fusion and electrofusion welded joints in HDPE piping.

Away from TWI he is chair of the British Institute of Non-Destructive Testing (BINDT) Membership, Qualification & Education Committee and sits on BINDT Council.
