Taw qhia rau Shandong Kungang Kauv Pipe
Cov kauv yeeb nkab yog tsim los ntawm dov qis-carbon carbon structural steel los yog low-alloy structural steel sawb mus rau hauv ib lub raj dawb paug raws li ib tug tej yam helical lub kaum sab xis (hu ua lub kaum sab xis), thiab ces welding cov yeeb nkab seams. Nws tuaj yeem ua tau nrog ib txoj hlua nqaim Steel ua cov kab loj loj steel kav. Nws cov lus qhia tshwj xeeb yog qhia los ntawm sab nraud * phab ntsa thickness. Cov yeeb nkab welded yuav tsum xyuas kom meej tias qhov kev ntsuam xyuas hydraulic, lub zog tensile ntawm cov vuam thiab qhov txias bending kev ua tau zoo yuav tsum ua raws li cov kev cai.
Nyob rau hauv cov nqe lus ntawm welding txheej txheem, welding txoj kev ntawm kauv welded yeeb nkab thiab ncaj seam steel yeeb nkab yog tib yam, tab sis ncaj seam welded yeeb nkab yuav inevitably muaj ntau T-zoo li tus welds, yog li qhov tshwm sim ntawm vuam tsis xws luag kuj yog heev nce, thiab cov welding residue ntawm T-shaped welds Qhov kev ntxhov siab yog loj, thiab cov hlau weld feem ntau yog nyob rau hauv peb-dimensional kev nyuaj siab lub xeev, uas ua rau kom muaj peev xwm ntawm cov kab nrib pleb. Ntxiv mus, raws li cov kev cai ntawm submerged arc vuam, txhua qhov vuam yuav tsum muaj qhov pib arc thiab qhov chaw tua hluav taws, tab sis txhua qhov ncaj seam welded yeeb nkab tsis tuaj yeem ua tau raws li qhov xwm txheej no thaum vuam lub voj voog, yog li yuav muaj ntau qhov vuam tsis xws luag.
siv
Kauv kav dej yog siv nyob rau hauv dej engineering engineering, petrochemical kev lag luam, tshuaj lom neeg kev lag luam, hluav taws xob fais fab kev lag luam, ua liaj ua teb irrigation, thiab kev tsim kho hauv nroog. Nws yog ib qho ntawm nees nkaum cov khoom tseem ceeb tsim los ntawm peb lub teb chaws. Rau kev thauj mus los ua kua: dej, dej ntws, dej phwj kho engineering, av nkos, kev thauj mus los hauv dej hiav txwv. Rau kev thauj mus los roj: roj, nkev, roj av kua roj. Rau lub hom phiaj: raws li piling kav thiab txuas hniav; cov kav dej rau wharves, txoj kev, lub tsev tsim, marine piling kav, thiab lwm yam.
Cov Qauv Khoom
Kauv seam submerged arc welded steel yeeb nkab SY5036-83 rau kev thauj mus los ntawm cov kua dej yog siv rau cov roj thiab cov kav dej; kauv seam siab zaus welded steel yeeb nkab SY5038-83 rau kev thauj mus los ntawm cov kua dej yog welded los ntawm kev siv ntau zaus lap vuam. Kauv seam high-frequency welded steel kav rau kev thauj mus los ntawm cov kua dej. Cov yeeb nkab steel muaj lub zog muaj peev xwm, zoo plasticity, thiab yooj yim rau vuam thiab ua; Lub kauv seam submerged arc welded steel yeeb nkab SY5037-83 rau kev thauj mus los ntawm cov dej tsis tshua muaj siab yog tsim los ntawm ob sab tsis siv neeg submerged arc vuam lossis ib sab vuam rau dej, roj, Submerged arc welded steel kav rau kev xa cov dej tsis tshua muaj siab. xws li cua thiab chav.
Feem ntau siv cov qauv rau cov kav hlau kav dej feem ntau muab faib ua: SY / T5037-2000 (tus qauv kev tswj hwm, tseem hu ua spiral seam submerged arc welded steel kav rau cov kav dej zoo tib yam), GB / T9711.1-1997 (tus qauv hauv tebchaws, thiab Lub npe hu ua roj thiab roj kev lag luam tsheb thauj mus los steel kav) Thawj feem ntawm kev xa khoom cov txheej txheem: A-qib steel yeeb nkab (GB / T9711.2 B-qib steel yeeb nkab nrog cov kev cai nruj), API-5L (American Petroleum Institute, kuj hu ua pipeline steel yeeb nkab; uas muab faib ua ob theem: PSL1 thiab PSL2), SY/T5040-92 (kauv submerged arc welded steel yeeb nkab rau pawg).
