The following checks and tests are carried out as part of our product quality control system,
to ensure the highest quality of products offered to our customers:
  • All raw materials are sourced from approved suppliers and audited, in order to ensure consistent parameters. In addition, the quality of our PE80 and PE100 raw materials is also tested and approved by an independent testing authority, for example Bodycote and Exova to ensure that these materials comply with the enhanced requirements of the PE100+ Association and related international standards requirements.

  • Comprehensive in-process and batch release checks ensure that all pipe, fittings and assemblies will deliver a system compliant with all relevant national, European and international controls, ensuring complete peace of mind for our customers.

  • A range of checks and tests is carried out on both pipe and fittings (see below). We perform some of these tests on every product (Batch Release Test ). Others only need to be carried out on a sample basis (TT and PVT: Type Test and Process Verification Test).

  • We keep detailed records of dimensional and performance tests for each production batch and every batch is given a unique identification number, providing customers with complete traceability.
