API 5L X52 sib npaug yog dab tsi?
API 5L X52 sib npaug cov yeeb nkab feem ntau muaj cov hauv qab no:
Los ntawm cov khoom siv zog: L360 cov yeeb nkab yeeb nkab yog ze rau API 5L X52 hais txog lub zog thiab lwm yam khoom, thiab feem ntau suav tias yog cov yeeb nkab sib npaug. Ntawm lawv, cov khoom sib npaug sib npaug rau API 5L X52 PSL1 yog L360; cov ntaub ntawv sib npaug sib npaug rau API 5L X52 PSL2 yog L360Q, L360M, L360N, thiab lwm yam.
Los ntawm cov txheej txheem sib txawv: Hauv lub teb chaws tus qauv GB / T9711, qee cov kav dej nrog cov lus qhia zoo sib xws thiab kev ua tau zoo kuj tuaj yeem siv los ua cov kav dej sib npaug ntawm API 5L X52 rau qee qhov, tab sis yuav muaj qee qhov sib txawv ntawm cov ntsiab lus xws li tshuaj lom neeg muaj pes tsawg leeg thiab mechanical zog.
Raws li cov qauv ntawm lwm lub teb chaws lossis cheeb tsam
Qee cov European txheem steel kav: xws li qee cov qib steel hauv EN 10208-2, uas zoo ib yam li API 5L X52 hais txog lub zog, tawv, corrosion kuj, thiab lwm yam, tuaj yeem siv los ua cov khoom sib npaug hauv qee cov kav dej thoob ntiaj teb. raws li cov kev xav tau tshwj xeeb, tab sis cov ncauj lus kom ntxaws kev sib piv thiab kev ntsuam xyuas yog xav tau hauv cov ntawv thov tiag tiag.
