Destructive testing of electrofusion welding

During the installation of a PE piping system, the quality of the welded joints is of crucial importance. The quality of PE welding can be guaranteed by a number of checks and examinations:

  • Checking for preparations and welding parameters before the start of the welding process
  • Control during and after the welding process on site
  • Ultrasonic PAUT examination of field welding on site
  • Visual and mechanical examination of (test) welding in an independent laboratory

Destructive testing in our own laboratory

Normec QS has laboratory facilities for the preparation and testing of PE electrofusion welding, here both field welding (on a sample basis) and test welding in accordance with the applicable standards (NTA 8828) can be tested.
