The new product produced by Dushanzi Petrochemical Company - high-density polyethylene pipe material TUB121N3000 compounding material, has passed the international PE100 level certification and obtained the qualification to enter the gas field. In March 2011, the TUB121N3000 compounding compound produced by Dushanzi Petrochemical High Density Polyethylene Plant commenced PE100 level certification testing at the Swedish National Laboratory. On May 8th this year, the Swedish National Laboratory completed all test items for raw materials and pipe products. The test results show that the product meets the ISO4437 gas-fired polyethylene pipe standard and the raw material grade reaches the PE100 level. At present, the PE100 grade pipe materials produced by Dushanzi Petrochemical have been promoted in the major markets of many pipe materials in South China and Southwest China. The use of several companies shows that PE100 grade pipe materials have excellent processing performance. Green Laser
