LSAW carbon steel yeeb nkab tau ib txwm cuam tshuam nrog kev sib kis ntawm roj thiab roj, tab sis nws cov yam ntxwv ntawm kev ua tau zoo ua rau nws sib npaug ntawm qhov hnyav -cov dej num xws li txuas hniav, chaw nres nkoj, siab- cov tsev nce siab, cov nroj tsuag muaj kev lag luam, thiab loj -cov vaj tse loj. Tsis zoo li cov kab me me welded kav,LSAW carbon steel yeeb nkabyog tsim los ntawm steel phaj los ntawm JCOE los yog UOE txoj kev ua raws li submerged arc vuam, ua rau lub cheeb loj, tuab phab ntsa khoom nrog zoo heev dimension stability thiab load- bearing muaj peev xwm. Thaum soj ntsuam los ntawm cov qauv kev tsim vaj tsev pom es tsis yog lub kaum sab xis kev thauj mus los nkaus xwb, LSAW carbon steel yeeb nkab qhia tau zoo tshwj xeeb hauv kev ua haujlwm ntawm lub zog, buckling tsis kam, thiab fabrication adaptability.
Geometric thiab Mechanical yam ntxwv
Loj Txoj kab uas hla thiab tuab phab ntsa muaj peev xwm
Ib qho ntawm cov yam ntxwv ntawm LSAW carbon steel yeeb nkab yog nws lub peev xwm ua kom tiav cov kab loj loj nrog cov phab ntsa tuab heev thaum tswj xyuas nruj. Cov kws tsim qauv tsim qauv feem ntau xav tau cov tubular cov tswv cuab uas tuaj yeem tiv taus axial compression, khoov lub sijhawm, thiab kev sib xyaw ua ke. Txoj kab hla- ntu ntawm cov yeeb nkab carbon steel faib cov kev ntxhov siab sib npaug, txo qhov kev ntxhov siab piv rau qhib - ntu kab teeb.
Vim tias LSAW manufacturing cia siab rau cov phaj hnyav dua li cov coil, phab ntsa tuab tuaj yeem nce ntxiv yam tsis muaj kev cuam tshuam qhov kev ncaj ncees. Qhov no tso cai rau cov neeg tsim qauv xaiv cov qib siab - lub zog xws li API 5L X65 lossis X70 rau cov qauv siv uas xav tau ob qho tib si lub zog thiab ductility. Nyob rau hauv kev sib piv nrog dov H-beams los yog lub thawv seem, tubular carbon steel yeeb nkab muaj kev txhim kho torsional rigidity thiab zoo nkauj yooj yim, tshwj xeeb tshaj yog nyob rau hauv raug architectural lug.
Cov lus hauv qab no qhia txog qhov dav dav ntawm LSAW carbon steel yeeb nkab siv hauv cov haujlwm ua haujlwm.
| Parameter | Hom kab mob | Cov yam ntxwv muaj feem xyuam |
|---|---|---|
| Sab nraud txoj kab uas hla | 406-1626 hli | Haum rau cov kab loj thiab pawg |
| Phab ntsa Thickness | 8mm-40 hli | Txhawb siab axial thiab dabtsi yog khoov loads |
