Qhov tseem ceeb ntawm kev txhim kho ntev seam submerged-arc welded yeeb nkab

Tam sim no, raj xa dej yog siv rau cov roj ntev thiab roj thauj mus los. Pipeline Steel Kave uas siv nyob rau hauv ntev-nrug pipelines feem ntau suav nrogMuab Kauv Submerged Arc Welded Hlau Kavthiab ncaj seam ob npaug ib sab ntawm submerged arc welded steel kav hlau. Vim tias cov kauv submerged arc welded yeeb nkab yog ua los ntawm sawb hlau thiab nws cov phab ntsa tuab yog txwv ntawm qib steel yog txwv los ntawm kev kho cua sov ntawm cov khoom siv cua sov. Tsis tas li ntawd, muaj qee qhov tsis txaus ntseeg ntawm kauv submerged arc Welded yeeb nkab, xws li ntev weld, loj residual kev ntxhov siab thiab kev ntseeg tau ntawm Weld. Nrog rau kev nce nce rau cov roj thiab cov roj txuas ntxiv hauv cov cheeb tsam muaj ntau ntxiv thiab cov cheeb tsam uas muaj kev ntseeg siab, thiabLOJ-diamer ncaj Welded Kavyog maj mam hloov cov khoom plig welded.

Tsis ntev los no, Tuam Tshoj tab tom nce kev txhim kho cov roj thiab roj nyob rau sab hnub tuaj Suav teb chaws. Nrog rau kev txhim kho cov roj phem rau qhov tob ntawm dej hiav txwv ntawm cov hiav txwv ntawm cov rog tau tshwm sim los ntawm kev sib xyaw ua ke ntawm cov kauv welded yeeb nkab. Txhawm rau txhim kho txoj kev thauj hluav taws xob kom ua rau cov raj xa pa roj hmab los txhim kho ntawm phab ntsa tuab, cov submarine pipeline feem ntau yog kev txawj ntse ncaj Welded yeeb nkab. Yog li ntawd, piv nrog kauv welded yeeb nkab muaj cov ntaub ntawv welded, yog li ntawm cov yeeb nkab welded ntau, ncaj Welded yeeb nkab kuj tseem yog thawj qhov kev xaiv.

Machinery, kev tsim kho, kev lag luam tshuaj thiab lwm yam kev lag luam xav tau ncaj welded kav dej. Tam sim no, sab hauv lub qhov rooj valve yog machined tom qab forging kev lag luam tshuab, uas yog siv sijhawm thiab siv cov khoom siv. Yog tias tuab-walled ncaj seam Welded yeeb nkab siv, nws yuav yog ntau dua kev lag luam. Ntxiv rau, vim cov cai ntawm cov neeg kho mob ntawm kev tawm tsam, tsuas yog cov kav hlau ncaj ncees yog siv rau cov kav dej tsim tsev; Ncaj welded yeeb nkab kuj tseem yuav siv rau cov kav dej siv tshuaj.
