On March 15, I learned from the Dushanzi Petrochemical Research Institute that the National Chemical Building Materials Testing Center recently sent a notice that the high-density polyethylene pipe material DGDZ-4620 produced by Dushanzi Petrochemical Company passed the ISO PE-RT type II classification and stereotype inspection.
, marking that Dushanzi Petrochemical DGDZ-4620 obtained the first domestic PE100 grade II type heat-resistant polyethylene permitting qualification

DGDZ-4620 is another pipeline special material that Dupeco has obtained the license after TUB121N3000B, TUB121N3000MB, DGDZ-3606 and T4401 and other raw materials for pipeline transmission and distribution systems

This product can achieve high-yield extrusion when processing small-diameter floor heating pipes, and has excellent sag resistance and dimensional stability when processing large-diameter thermal pipes.
Tensile-yield and welding compatibility can meet the requirements of municipal heat pipes

The successful passing of the qualification certification this time will further increase the market share and customer recognition of DGDZ-4620 in the fields of floor heating pipes and heat pipes, and help Dushanzi Petrochemical Company to steadily advance its differentiation and high-end strategy and continue to improve its economic benefits
