Vim li cas Txoj Kev Xaiv Ncaj Nraim Hlau Thawj qhov kev xaiv rau cov roj thiab roj thauj?
Ncaj seam steel yeeb tau dhau los ua qhov kev xaiv thawj zaug vim tias nws muaj peev xwm weld zoo (x80 style bearing muaj peev xwm ua tau zoo tshaj 15mpa). Piv nrog kauv welded kav dej, nws welds yog luv thiab qhov tshwm sim ntawm kev tsis xws luag yog tsawg. Daim ntawv sau npe qub steel hlau los ntawm API 5L PSL2 tuaj yeem ua tau raws li cov kev xav tau ntawm cov acidic ib puag ncig. Tsis tas li ntawd, cov duab geometric qhov tseeb ntawm ncaj seam kav kav yog siab dua, uas yooj yim rau sab xaib taub qab vuam. Hauv cov phiaj xwm xws li "East-East-East-East-East Rauv Submerged Arc Welded Kav (LSAWW) rau ntau tshaj 70%.
Yuav ua li cas xaiv ncaj seam steel kav hauv tsev qauv qauv?
Q355B Ncaj Seam Welded kav yog ib txwm siv hauv tsev cov qauv hlau. Lawv cov txiaj ntsig lub zog yog ntau dua los yog sib npaug rau 355MPA thiab lawv muaj seismic zoo heev. Square thiab duab plaub fab feem ntau yog siv rau kab thiab kab teeb. Tom qab khoov txias, lawv yuav tsum tau annealed los tshem tawm kev ntxhov siab. Nyob rau hauv cov tsev siab nce, cov kab uas muaj ntau-ntsa ncaj ncaj ncaj rau ntawm cov kav dej ncaj Hluav taws retardant txheej thiab galvanizing yog cov qauv kev tiv thaiv xeb rau cov kav dej.
Cov Kev Tshwj Xeeb Rau Ncaj Seam Steel Kav Hauv Cov Haujlwm Conservancy?
Cov dej num hauv cov dej num yuav tsum muaj cov kav hlau loj kom tsis txhob muaj kev phom sij thiab cov microster sab hauv yog cov tfeed tar lossis txoj hlua khi nrog cov cement cug. Kev Kuaj Siab Siab yuav tsum xeem dhau GB \/ T 3091 Cov Khoom Siv Siab Dej Siab, thiab cov khoom siv Q235b yog xaiv thaum ua haujlwm siab tsawg dua lossis sib npaug ntawm 2.5mpa. Cov kav dej steel rau cov dej sib txawv yuav tsum txiav txim siab tsis zoo lub siab, thiab lub nplhaib tsis ncaj ncees yuav tsum muaj ntau dua lossis sib npaug rau 8knon \/ M².
Vim li cas cov tsheb tuam ntxhab siv cov khoom lag luam nyias-walled ncaj ncaj rau seam welded kav?
Lub phab ntsa tuab ntawm ncaj seam kav rau cov chasab thiab tso pa tawm yog tsuas yog 1.} Mm, thiab cov txheej txheem ERW yog siv los xyuas kom meej lub tiaj tiaj ntawm WELD. Cov ntaub ntawv feem ntau yog 4 {0 9l stainless hlau (cov tshuab kub siab oxidation) lossis dp600 qhov hnyav (30% qhov hnyav txo). Qhov kev nkag siab ntev ntev yuav tsum tau tswj tsis pub dhau ± 0.1mm kom zam dhau kev cuam tshuam los sib dhos. Laser Welded kav tau siv nyob rau hauv lub zog hluav taws xob me me ntim cov txheej txheem.
Dab tsi yog cov kev txwv ntawm ncaj seam steel kav hauv cov khoom siv tshuaj lom neeg?
Txawm hais tias 316L ncaj cov yeeb nkab yog kua qaub thiab alkali resistant, haastelloy C276 yuav tsum tau siv rau hauv cov khoom siv hluav taws xob hydrofric acid ua haujlwm. Kev siab siab tau txais yuav tsum tau forged raws li tag nrho, vim hais tias lub hoop kev nyuaj siab ntawm ncaj seam kav yog tsuas 80% ntawm cov kav dej seamless. Thaum qhov kub tshaj 450 degree, Tp347h Austenitic Stainless hlau yuav tsum siv thiab daws kho.
