LSAW Pipes

Ncaj seam submerged arc welded (LSAW) carbon steel yeeb nkab yog ib tug nto acoustic yoj steel yeeb nkab ua los ntawm kub dov steel daim hlau los ntawm JCOE los yog UOE txoj kev siv tshuab. JCOE thev naus laus zis sawv cev rau kev tsim thiab tsim cov txheej txheem thaum lub sijhawm tsim khoom, nrog rau kev sib txuas sab hauv thiab sab nraud thiab kev nthuav dav txias ua tom qab vuam.

Khoom Taw qhia

Ncaj seam high-frequency welded steel kav muaj cov yam ntxwv ntawm cov txheej txheem yooj yim thiab ceev nruam ntau lawm ceev. Lawv tau siv dav hauv kev tsim kho pej xeem, kev lag luam petrochemical, kev lag luam teeb thiab lwm yam haujlwm. Nws feem ntau yog siv los thauj cov kua dej uas tsis tshua muaj siab lossis ua rau ntau yam engineering thiab cov khoom lag luam teeb pom kev zoo.
