FAQ (Cov lus nug nquag nug)
Q1: Qhov txawv ntawm PSL1 thiab PSL2 ntawm API 5L yeeb nkab yog dab tsi?
PSL2 yog qib hwm ntawm API 5L kab yeeb nkab nrog cov kev cai nruj dua li PSL1. Nws siv cov kev txwv sab sauv thiab qis dua rau kev tawm los thiab lub zog tensile, txwv qhov tawm los -tensile ratio nyob rau hauv 0.93, mandates qis-kub Charpy cuam tshuam kev ntsuam xyuas, thiab muaj kev tswj nruj dua carbon, sulfur, phosphorus thiab lwm yam impurity hais. PSL2 cov kav dej muaj kev nyab xeeb dua, tawv thiab ua haujlwm ntev, haum rau siab -siab, sab nraud thiab qhov tseem ceeb ntev- cov kav dej txuas mus, thaum PSL1 tsuas yog rau cov pa qis- siab cov kav dej.
Q2: Dab tsi yog SAWL longitudinal welded yeeb nkab, thiab dab tsi yog nws qhov zoo dua SSAW kauv yeeb nkab?
SAWL yog hais txog longitudinal submerged arc welded yeeb nkab, nrog ncaj weld seam raws cov yeeb nkab lub cev. Piv nrog rau SSAW kauv welded yeeb nkab, SAWL yeeb nkab muaj luv dua thiab zoo dua weld seams, qis vuam residual kev nyuaj siab, siab dua qhov tseeb, zoo dua siab tsis kam thiab qaug zog. Nws yog qhov tsim nyog rau qib siab - qib, siab - siab thiab ntev - deb ntawm cov phiaj xwm tseem ceeb ntawm cov kav dej, nrog rau kev nyab xeeb tag nrho.
Q3: Cov kev ua haujlwm zoo li cas yog X65 thiab X70 qib haum rau feem?
X65 PSL2 yog qhov tsim nyog rau nruab nrab thiab siab - cov pa roj thiab cov pa xa hluav taws xob, cov kav dej hauv nroog loj thiab cov kav dej petrochemical uas muaj kev ua haujlwm ruaj khov. X70 PSL2 muaj cov txiaj ntsig zoo dua thiab lub zog tensile, siv tau rau ntev - nrug hla- lub teb chaws cov kav dej, cov kav dej hauv dej hiav txwv, thiab siab - cov phiaj xwm xa mus rau hauv qhov nyuaj thiab hnyav geological ib puag ncig, uas yog qib tseem ceeb rau cov loj - cov phiaj xwm xa hluav taws xob.
