3.5M. Its aim is to design, manufacture and validate a phased array ultrasonic system that can be used to inspect pipe-to-pipe and pipe-to-fitting (elbows, bends, reducers, tees) BF and EF joints in PE pipes, which is site-rugged and simple to operate. The concept is to have a ISO - ISO/TS 22499:2019 - Thermoplastic pipes for the This document describes the phased array ultrasonic testing (PAUT) of polyethylene butt fusion (BF) joints, including pipe-to-pipe, pipe-to-fitting and fitting-to-fitting joints, used for the conveyance of fluids.
Feb 28, 2020 · Phased Array Ultrasonic Testing (PAUT) of HDPE Pipe UT is a well-known and widely used inspection technique for non-destructive evaluation of metals, composites, and various non-metallic structures [ 33, 34, 35, 36 ]. In UT, high-frequency waves propagate inside the sample. Phased Array Inspection Solution for HDPE Butt WeldsPhased array and microwave inspection of HDPE materials have been reported elsewhere [1-3, 5-8]. This paper presents a phased array inspection solution for detection and sizing of LoF-type defects in HDPE weld specimens. 2. Inspection Solution 2.1. Inspection Method HDPE is a material with high attenuation ultrasonic. Shear waves are not supported in Phased Array Ultrasonic Testing of Welded Joints in joints using phased array ultrasonic testing (PAUT) [4-7]. There are commercial ultrasonic inspection systems for plastic pipes in North America and South Korea [8,9]. However, none of the systems provide a complete solution to the inspection problem. The American system is limited to BF joints and uses conventional
- Key FeaturesAn Innovative Solution to A Long-Standing ProblemCase StudiesPolyTest brings numerous benefits to industry:1. One system for inspecting both EF and BF joints in PE pipes 2. Fully portable system allowing in-trench pipeline inspection 3. Can inspect welded joints between pipes and reducers, elbows and tee fittings 4. Validated inspection system backed up by structural assessment data developed through long-term performance testing 5. Critical flaw sizes and acceptance criteria determined for butt fusion and electrofusion welds in various PE pipe materials 6. SPhased Array Ultrasonic Inspection on PE Pipe Heat Ultrasound phased array inspection can inspect fusion area in many positions. By making proper selection such as the inspection position, the scan direction and the probe, ultrasound phased array is for scanning areas difficult to be tested, and finish inspection on PE pipe

Ultrasonic phased array inspection of polyethylene damaged A test campaign has been carried out by ENGIE Lab-CRIGEN in order to evaluate the acuity of the Phased Array Ultrasonic Technique (PAUT) for detecting and sizing calibrated defects implanted at the inner surface of a PE pipe.These calibrated defectshad four different geometries, called V-shaped, half-V shaped , semi-ellipticaland rectangular, respectively.
The Ultrasonic Phased Array Inspection of Electrofusion Joints in Polyethylene Pipes. Colin BIRD, Delphine CARAVACA, Davide KLEINER TWI Limited, Cambridge, United Kingdom. Abstract. Electrofusion joints for polyethylene pipe are one of the common joining methods used in the water and gas industries for distribution pipelines.
