China’s leading low temperature stainless steel pipe manufacturer for LNG Hay:A02ZJJL


For a long time, China's low-temperature stainless steel pipelines have basically relied on imports. Due to the operating environment of LNG at about minus 160 degrees, only special materials can be used for pipeline transportation. Previously, there were only about 3 companies in the world that could produce it. Before that, China's largest LNG ship builder The LNG cryogenic stainless steel pipes used by Hudong-Zhonghua Shipbuilding (Group) are all imported, and the products are mainly from Europe and Japan.


In 2012, ZJJL and Hudong-Zhonghua Shipbuilding (Group) signed a whole ship stainless steel pipe order for 4 172,000 cubic meters LNG ships, realizing the localization of stainless steel pipes for the whole LNG ship for the first time.


As the leader of LNG pipelines in China, the project of “Large Diameter Pipelines and Components for LNG Transportation with an Annual Output of 20,000 tons” built by the company was put into operation in November 2013. The upgrade and supplement mainly meet the demand for high-end stainless steel welded pipes in China's oil and gas transportation field, especially oil and gas transportation under high corrosion, low temperature and high pressure conditions (such as LNG transportation).

The current major suppliers of the LNG cryogenic stainless steel pipe market include the company, JSWJ Stainless Steel Technology Corporation, South Korea's LS Metal, and several Italian players.
