Shanghai Petrochemical has passed two industrial trial productions.
Recently, the special black material for high-density polyethylene has achieved a technological breakthrough, meeting the performance requirements for the manufacture of large-diameter gas pipelines above 800 mm in China.
.
Gas pipelines with a diameter of less than 400 mm made of black materials are already common in the market
.
It is understood that small-diameter pipes made of domestic high-density polyethylene black materials will not "sag" when the pipelines are connected by the hot-melt process
.
The Plastics Department of Shanghai Petrochemical has accumulated long-term experience in the preparation of black materials for small-diameter pipes.
The products have obtained the internationally authoritative PE100+ certification, and successfully signed a contract with China Gas Group in 2019, becoming the first Chinese company to enter the core domestic gas pipeline market.

It is understood that this black material can not only be used for the pipeline manufacturing of large-diameter municipal backbone networks, but also has broad application prospects in the field of process pipeline manufacturing involving key industries of national economy and people's livelihood, such as energy and mining
