Gas steel kav yog hlau tubing tsim los ntawm carbon steel los yog hlau alloy, feem ntau yog siv rau conveying tsawg- cov kua dej xws li thee gas, roj av, thiab natural gas, raws li zoo raws li rau cov qauv kev tsim kho. Lawv tau muab faib los ntawm kev kho saum npoo rau hauv cov kav dej galvanized (cov kav hlau dawb) thiab cov kav tsis yog -galvanized (cov kav hlau dub), thiab los ntawm phab ntsa tuab rau hauv cov kav dej, cov kav dej tuab, thiab nyias - cov kav dej uas muaj phab ntsa.
Cov ntaub ntawv muaj xws li cov qib carbon steel xws li Q195, Q235, Q345, thiab L290GA alloy steel, tsim siv hluav taws xob tsis kam vuam (ERW) thev naus laus zis. Qhov kev tiv thaiv corrosion muaj xws li galvanizing, roj txheej, thiab tshuaj pleev xim. Khoom specifications npog txheej diameters ntawm 20-508mm, phab ntsa thicknesses ntawm 1.5-60mm, thiab ntev ntawm 5.8-13m. Cov qauv kev ua raws li cov qauv thoob ntiaj teb xws li API 5L / 5CT, ASTM A53, thiab EN10208.
