GF Piping Systems has over 50 years of experience in developing thermoplastic raw materials for use in pressure bearing pipe systems. It is fundamnetal to enable production of quality products that the correct and best possible raw material is used. As part of its global quality control system, GF Piping Systems, specifies strictly its raw materials and quality controls the supplied mateiral by the use of goods inwards testing.

During resin polymerisation, all the production parameters are controlled on-line, such as:
-  ethylene, hydrogen, comonomer concentrations
-  reactor temperature
-  residence time
-  catalyst                                  

Basic properties like melt flow rate (MFR), density, thermal stability (OIT), carbon black dispersion certificate of analysis according to EN 10204-3.1. Mechanical tests shall be performed every year at external institutes to guarantee the raw material quality and its conformity to the initial approval.

All test reports for all the Ineos HDPE are available on request. Additional internal pressure tests are regularly performed by Ineos to guarantee a consistent quality.

GF Piping Systems quality control systems include short term as well as long term testing. The test criteria use are based on internationally recognised standards. On top of standardised testing many of GF's products are certifed by independent certification bodies, suchg as KIWA, DIBT, DNVGL, and many ,many more.

Two examples below show witnessed certification testing by DNVGL (for approval of PE-100 and COOL-FIT in the global marine industry (IMO A.753)
