I. Yam khoom yog dab tsiAPI 5L
1. API5L-B pipeline steel, sib npaug rau L245 hom Wuyang Hlau thiab hlau, L245 belongs rau qis alloy series, tus nqi kuj yog siab, tus nqi ntawm cov khoom sib txawv tsis zoo ib yam, feem ntau yog siv rau cov kav dej, cov kav dej ntuj, thiab lwm yam., yog cov kav dej tsis tshua muaj siab, nws qhov kev ua tau zoo thiab 20 # seamless yeeb nkab yuav luag.
2. Cov khoom siv yogx52 qib pipeline steel yeeb nkabkab hlau, uas yog ib hom hlau nrog tshwj xeeb uas yuav tsum tau siv rau conveying roj thiab natural gas pipelines.Raws li lub thickness thiab tom qab tsim, nws muaj peev xwm ua tau los ntawm kub nruam dov zeb, rauv dov zeb los yog nruab nrab tuab phaj zeb thiab tsim rau hauv loj txoj kab uas hla steel yeeb nkab los ntawm kauv vuam los yog UOE ncaj seam vuam.
3. Seamless lossis welded steel yeeb nkab, tus qauv yogAPI 5L (pipeline yeeb nkab) PSL2yog ib qho ntawm cov qib, lwm qhov yog PSL1 nyob rau hauv kev sib piv, PSL2 yuav tsum siab tshaj PSL1API 5L yog cov yeeb nkab yeeb nkab specification formulated los ntawm American Petroleum Institute, B yog ib tug ntawm cov pipeline steel qib.
II.API5L tus qauv
1.API5L tus qauv, tus naj npawb ntawm cov pob qij txha ntawm steel PIPE thiab PIPE WLD 10 "SCH STD API5L ASTM A106 GRB seamless steel yeeb nkab nyob rau hauv tib seem yuav tsum tsis pub tshaj 50% ntawm cov kav dej. ntxuav lub qhov ntawm qhov xyaum los yog cov cua kub siab kom tshem tawm cov scum hauv lub qhov kom paub tseeb tias lub aperture (qhov aperture yuav tsum tsis pub tsawg tshaj 127cm) ua tau raws li qhov yuav tsum tau ua thiab tiv thaiv lub qhov ntsaws.
2. Cr: ≤025 Nickel Ni: ≤030 Copper Cu: ≤025 Mechanical zog: Tensile lub zog ntawm sigma b (MPa): 560 (57) los yog siab dua yield zog sigma s (MPa): 335 (34) los yog siab dua elongation delta (%) : acuity txo ntawm thaj tsam ntawm 18 ntsis (%) : 45 los yog siab dua tej yam zog Akv (J): 55 los yog siab dua tej yam toughness qhov tseem ceeb ntawm alpha kv (J / cm2).
3.API 5L tus qauv npog qhov yuav tsum tau ua ntawm cov raj xa dej steel, tshwj xeeb tshaj yog rau lub zog tensile, yield zog, chav kub cuam tshuam toughness, elongation ntawm so, thiab lwm yam. cov yeeb nkab steel, ntawm cov yeeb nkab steel dav dav tau muab faib ua cov yeeb nkab zoo tib yam thiab lub zog siab steel yeeb nkab, API 5L tus qauv kuj suav nrog cov txheej txheem tsim cov yeeb nkab steel.
III, API5Lgrb khoom yog dab tsi
1. API 5LGRB yog seamless los yogwelded steel yeeb nkab, tus qauv yog API 5L (petroleum pipeline pipeline), PSL2 yog ib qho ntawm cov qib, lwm qib yog PSL1 hauv kev sib piv, PSL2 yuav tsum siab dua PSL1API 5L yog cov yeeb nkab yeeb nkab specification tsim los ntawm American Petroleum Institute, B yog ib hom ntawm pipeline steel qib.
2.ASME SA517, ASTM A517 siab nkoj quenched thiab tempered siab zog alloy steel phaj ASME SA517 / SA517M tus qauv suav nrog: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SAG5r, SAG7rP, SA51, SA517GrPASTM A517 / A517M tus qauv suav nrog: A517GrA, .
3. Khoom sivAPI 5L PSL2txheemkauv steel yeeb nkabGrB-X70 Sab nraud txoj kab uas hla 219-3650 mm Nyob zoo, peb tau tsim cov kauv yeeb nkab rau 24 xyoo, peb vam tias yuav muaj lub sijhawm los koom tes nrog koj.
