The insulation joint for the west-east gas pipeline enters the installation test stage

　　The new large diameter insulating joint of jyga-120 PN12MPa DN1200mm developed by our company in 2016 is the first to be developed in China in accordance with the new standard SY/t0516-2016(our company is one of the new standard making units).In September 2016,it passed the expert appraisal organized by China machinery industry federation,and the expert committee unanimously agreed that the high-pressure large-caliber insulated joint produced in China for the first time according to the new standards of SY/t0516-2016 can provide products of international advanced level for oil and gas pipeline network transportation and trunk pipeline.

　　In February this year,our company participated in the bidding of the three-wire PN12MPa DN1200mm insulation connector of the west-east gas transmission line,and won the bidding at one stroke.Now the insulating joint has entered the stage of pressing and testing.In the near future,the new large diameter insulated joint produced by our country will be used for the first time on the west-east gas pipeline.
