Qib:GRB, X42, X46, X52, X56, X60, X65, X70 X80
Qhov ntau thiab tsawg:
Tawm txoj kab uas hla: 1/2 nti --- 24 nti
Phab ntsa Thickness: SCH10,SCH20,SCH40,SCH STD,SCH80
Ntev: 1m--18m
Txheej:3PE txheej, 3PP txheej, FBE txheej; Epoxy txheej, pleev xim tshwj xeeb
Manufacturing thiab Processing:
Cov kav hlau no feem ntau yog tsim los ntawm cov txheej txheem kub dov thiab yuav tsum tau kho cua sov thaum xa khoom kom ntseeg tau tias muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov kav dej.
Daim ntawv thov teb:
Vim lawv cov khoom zoo heev compressive thiab corrosion kuj, X52 pipeline steel kav yog dav siv nyob rau hauv kev thauj mus los ntawm cov roj thiab roj nyob rau hauv av thiab nyob rau hauv hiav txwv, nrog rau tej yaam num tseem ceeb xws li tob - hiav txwv pipelines thiab transcontinental pipelines.
