3. Dab tsi yog qhov sib thooj Suav tus qauv qib rau ASTM A501 welded carbon steel structural yeeb nkab, thiab dab tsi yog qhov txawv ntawm kev siv cov qauv?
Teb: ASTM A501 welded carbon steel qauv yeeb nkab sib haum rau GB / T 6728 Q235A welded structural yeeb nkab hauv Suav qauv. Nyob rau hauv cov nqe lus ntawm cov qauv siv, ob qho tib si siv rau lub hom phiaj dav dav, tab sis muaj qhov sib txawv: ASTM A501 feem ntau yog siv rau welded cov yam ntxwv xws li thav ntawv, kev txhawb nqa thiab brackets, tsis muaj qhov yuav tsum tau muaj kev cuam tshuam toughness, thiab lub zog tensile yam tsawg kawg nkaus yog 330 MPa, lub zog yield tsis tsawg dua 18 MPa; GB / T 6728 Q235A muaj tib yam khoom siv raws li ASTM A501, tab sis nws yog siv ntau dua hauv kev tsim hluav taws xob hauv tsev, xws li kev cob qhia me me, lub tsev ib ntus thiab lwm yam xwm txheej. Qhov txawv yog tias Q235A muaj cov kev cai nruj dua ntawm qhov zoo ntawm cov yeeb nkab, thaum ASTM A501 muaj cov kev xav tau hloov pauv ntau dua ntawm cov yeeb nkab formability, uas yog tsim rau kev tsim cov txheej txheem nyuaj.
4. Yam Suav tus qauv welded yeeb nkab qib twg sib haum rau ASTM A135 Qib B welded yeeb nkab, thiab lawv qhov sib txawv ntawm kev thauj mus los yog dab tsi?
Teb: ASTM A135 Qib B welded yeeb nkab (carbon steel welded yeeb nkab rau roj kis tau tus mob) sib raug rau GB / T 3091 Q235B welded yeeb nkab hauv Suav qauv. Hais txog kev ua haujlwm ntawm kev thauj mus los ntawm cov kua dej, ob qho tib si yog siv rau kev thauj mus los ntawm cov pa roj tsawg, tab sis muaj qhov sib txawv: ASTM A135 Qib B muaj cov kev cai nruj ntawm cov cua nruj ntawm cov yeeb nkab, thiab cov vuam yuav tsum dhau qhov kev ntsuas nruj kom tsis txhob muaj cua nkag, uas yog tsim rau cov pa roj carbon monoxide, coal gas thiab lwm yam roj xa mus kav; GB / T 3091 Q235B kuj tseem muaj huab cua nruj, tab sis tus qauv ntsuas qis dua me ntsis ntawm ASTM A135 Qib B, thiab feem ntau siv hauv cov kav dej hauv nroog hauv nroog thiab cov kav dej hauv nroog. Tsis tas li ntawd, ASTM A135 Qib B muaj qhov yuav tsum tau ua ntau dua rau cov vuam seam lub zog tensile, uas yog tsim nyog rau ntev -ntaub kis tau tus mob ceg.
5. Dab tsi yog qhov kev sib raug zoo ntawm API 5L X60 welded yeeb nkab thiab Tuam Tshoj tus qauv welded yeeb nkab, thiab lawv cov txiaj ntsig zoo li cas hauv kev siab - roj thiab roj tsheb thauj mus los?
Teb: API 5L X60 welded yeeb nkab sib haum rau GB / T 9711.1 L485 welded yeeb nkab hauv Suav qauv. Ob leeg muaj qhov zoo tshaj plaws nyob rau hauv siab - siab roj thiab roj tsheb thauj mus los: API 5L X60 muaj lub zog tensile yam tsawg kawg nkaus ntawm 600 MPa, lub zog tawm los ntawm 415 MPa, siab zog, zoo toughness thiab corrosion kuj, uas tuaj yeem tiv taus siab (txog 14 MPa) thiab txo cov phab ntsa thickness ntawm cov yeeb nkab, yog li txo tus nqi ntawm kev tsim kho; GB/T 9711.1 L485 muaj qhov tseem ceeb tib yam khoom siv raws li API 5L X60 (lub zog tensile 570-720 MPa, yield zog Ntau dua los yog sib npaug rau 485 MPa), thiab yog optimized rau hauv tsev siab - siab roj thiab roj tsheb thauj mus los, nrog zoo weldability, 1 cycle stability {9} ntawm ntev -kab raj xa dej. Tsis tas li ntawd, ob qho tib si ua tau raws li cov qauv thoob ntiaj teb, ua kom muaj kev sib hloov ntawm cov kav dej hauv kev hla ciam teb roj thiab cov dej num.
