API 5L siv rau dab tsi?
ANSI / API 5L qhia txog kev tsim khoom ntawm ob theem khoom (PSL1 thiab PSL2) ntawmseamless thiab welded steel yeeb nkab rau kev siv cov kav dej hauv kev thauj mus los ntawm cov roj av thiab cov nkev.
Puas yog API 5L carbon steel?
API 5L cov kav dej yogcarbon steel kav siv rau cov roj thiab roj xa mus. Lawv suav nrog cov kav dej tsim hauv seamless thiab welded (ERW, SAW). Cov qib suav nrog API 5L Qib B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore thiab qaub cov kev pabcuam.
Puas yog API 5L zoo ib yam li A106?
Cov tshuaj muaj pes tsawg leeg ntawm ob qhov ntau thiab tsawg sib txawv ntawm cov pa roj carbon feem pua.ASTM A106 yeeb nkab tsuas muaj cov pa roj carbon, thaum API 5L yeeb nkab tuaj yeem muaj cov pa roj carbon thiab alloy hlau sib xyaw.. ASTM A106 yeeb nkab muaj cov ntsiab lus siab tshaj plaws ntawm 0.25% thiab qhov siab tshaj plaws manganese cov ntsiab lus ntawm 0.27%.
Qhov kub siab tshaj plaws rau API 5L yog dab tsi?
Tsawg kub ntau yam: API 5L PSL2 yeeb nkab yog tsim los rau kev ua haujlwm siab tshaj plaws ntawm120 ° F (49 ° F). Rau cov ntawv thov kub dua, cov khoom siv los yog siab dua - cov kav dej yuav tsim nyog.
Ntev npaum li cas rau API 5L?
Kwv yees ntev yuav tsum tau xa nyob rau hauv ib tug tolerance ntawm+/- 500 hli (+/- 20 nti). Qhov ntev ntev ntawm API 5L steel kab yeeb nkab yog tsim los ntawm 6 m, 8 m, 9 m, 10 m thiab 12 m. Qhov ntev kuj tuaj yeem kho raws li cov kev xav tau tshwj xeeb.
