On June 12th,there is a good news from CNPC Tubular Goods Research Institute that the trial mass production of API 5L X80 heating induction bends which OD in 1422mm and wall thickness in 25.7mm,30.8mm and 33.8mm respectively produced by JULONG Steel Pipe Co.,Ltd have passed all the random examination at once,and their performance are even higher than the standard.
JULONG steel pipe is located in Cangzhou City,Hebei Province,which is famous in the steel pipes and fittings industry.This test was extremely strict and no secondary detection is allowed in these testing programs.If can’t pass at one time,the production must start again from beginning.The JULONG company has passed the unit trial production before this time.This small batch trial production is organized by its building project department and its target market isthe eastern line of Sino-Russia Natural Gas Pipeline Project.
