Chemical Cheebtsam
API 5L X42 PSL1 Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg uas yuav tsum tau muaj rau PSL1 kuj tau so, nrog rau lub hom phiaj los xyuas kom meej lub weldability thiab toughness ntawm cov khoom.
API 5L X42 PSL2 Chemical Composition
PSL2 muaj kev tswj xyuas nruj dua ntawm cov tshuaj muaj pes tsawg leeg kom ntseeg tau tias muaj kev ua tau zoo dua thiab kev ua tau zoo rau qhov xav tau ntau dua thiab siv tau.
Qee qib ntawm PSL2 tubing tau tsim tshwj xeeb rau kev siv tshwj xeeb, suav nrog cov khoom siv "S" thiab "O".Lub ntsiab lus "S" qhia tau hais tias cov yeeb nkab yog tsim los rau cov cheeb tsam qaub, thaum cov kav dej nrog "O" yog tsim los rau thaj chaw sab nrauv.
Vim tias cov cheeb tsam no tshwj xeeb yog corrosive, corrosion kuj ntawm steel yeeb nkab yog txhim kho los ntawm kev hloov cov tshuaj muaj pes tsawg leeg.
