At 10:00 on January 20, Zhongke Refinery's high-density polyethylene unit switched to PE100 grade bimodal pipe material XS10N for the first time.
The successful production of this brand has filled the market gap in the south of the Yangtze River
.
The material has excellent low-temperature impact resistance and stress cracking resistance, as well as super slow cracking resistance.
It can be used for pressure pipes such as gas pipes and water pipes.
It is a high-end pipe product that is in short supply in the South China market.

.
The material has excellent low-temperature impact resistance and stress cracking resistance, as well as super slow cracking resistance.
As one of the three sets of Total double-loop pipe processes introduced in China, Zhongke Refinery Zhongke Refinery took the lead in producing PE100 grade bimodal pipe materials without the guidance of patent owners and reliable experience parameters for reference
.
XS10N is the brand with the lowest production density at present, with a large amount of hexene added and extremely strict requirements for temperature control
.
In order to avoid fluctuations in the amount of hexene added, resulting in delayed reaction heat removal or fouling of the inner wall of the reactor, Tan Ganzu, Lu Xingyan, Wang Liang, and Deng Xuedong closely watched the reaction temperature and the heat removal margin of the tempering water system to ensure the reaction.

With the joint efforts of all the staff of the device, the first switching process was achieved within 18 hours, which also accumulated valuable experience for the next round of switching
