API 5L GR.B SSAW Yeeb Nkab

API 5L GRB kauv welded yeeb nkab yog cov qauv tshwj xeeb rau cov kav hlau uas tsim los ntawm American Petroleum Institute. Feem ntau, API 5L GRB kauv welded kav tau tsim los daws cov kev txwv ntawm API 5L GRB ncaj seam welded kav. Vim muaj kev txwv kev siv tshuab, cov kav dej ncaj seam welded tsis tuaj yeem tsim nyob rau hauv loj diameters. Yog li ntawd, kauv vuam yog siv los tsim cov kab loj API 5L welded kav rau kev thauj mus los ntev. Feem ntau, API 5L GRB muab kauv welded kav muaj txoj kab uas hla tshaj 508mm. GNEE Group yog tus kws tshaj lij ntawm cov kav dej welded. Yog tias koj xav tau API 5L GRB kauv welded kav, thov koj xav tiv tauj peb.

Kev sib piv tus qauv zoo rau API 5L GRB Kauv Pipes

1. PSL2 Cov Qauv Zoo yog siab dua PSL1
Ob theem kev qhia tshwj xeeb, PSL1 thiab PSL2, sib txawv tsis yog hauv kev tshuaj xyuas tab sis kuj tseem muaj cov tshuaj lom neeg thiab cov khoom siv kho tshuab. Yog li ntawd, thaum txiav txim raws li API 5L, daim ntawv cog lus yuav tsum qhia cov khoom specification theem, piv txwv li, PSL1 los yog PSL2, ntxiv rau cov kev ntsuas ib txwm muaj xws li loj thiab steel qib. PSL2 muaj qhov yuav tsum tau nruj dua li PSL1 hais txog cov tshuaj muaj pes tsawg leeg, tensile zog, cuam tshuam lub zog, thiab tsis muaj kev puas tsuaj.

2. Cov kev xav tau ntawm kev ua tau zoo
PSL1 tsis tas yuav muaj kev cuam tshuam kev ua haujlwm. Rau PSL2, tag nrho cov qib steel tshwj tsis yog X80 yuav tsum muaj tag nrho-loj cuam tshuam lub zog (Akv) nruab nrab tus nqi ntawm 0 degree : longitudinal Ntau dua lossis sib npaug rau 41J, transverse Ntau dua lossis sib npaug rau 27J. Rau X80 steel qib, tag nrho-loj cuam tshuam lub zog nruab nrab tus nqi ntawm 0 degree: longitudinal Ntau dua lossis sib npaug rau 101J, transverse Ntau dua lossis sib npaug rau 68J.

3. Kev Ntsuas Hydrostatic thiab Kev Ntsuas Tsis Zoo
Txhua API 5L GRB kab yeeb nkab yuav tsum tau kuaj xyuas hydrostatic. Tus qauv tsis tso cai rau kev sim tsis muaj kev puas tsuaj los hloov kev sim hydrostatic, uas yog qhov sib txawv ntawm API cov qauv thiab cov qauv Suav. PSL1 tsis tas yuav tsum tau kuaj tsis muaj kev puas tsuaj, qhov PSL2 yuav tsum tau kuaj tsis muaj kev puas tsuaj rau txhua cov yeeb nkab.
