Lub ntsiab lus ntawm kev lag luam hluav taws xob, tshwj xeeb tshaj yog nyob deb ntawm cov roj pipeline tsim los txhawb kev txhim kho cov kav dej loj LSAW, kev ua lag luam tam sim no, kev lag luam hauv tsev thiab txawv teb chaws hauv kev xav tau ntawm cov kav dej thiab cov roj av los ntawm kwv yees li 8 lab T, cov khoom lag luam xyoo 1100 lab t. , kev sib tw ua lag luam ntau dua, kev txhim kho yav tom ntej ntawm txoj kab ncaj nraim submerged arc welded yeeb nkab:
1, nyob rau hauv cov nqe lus ntawm av-siv raj, ib leeg-tube roj ntim mus txog 50 billion m3 / ib theem, txoj kab uas hla 1422mm, steel qib X80, roj siab 12MPa.
2, nyob rau hauv cov yeeb nkab dej hiav txwv sib txuas, los tsim cov roj av sib sib zog nqus (qhov tob ntawm 1500m saum toj no) cov kab kev taw qhia; marine lug mus rau high-strength yeeb nkab, loj phab ntsa thickness ntawm txoj kev loj hlob, piv txwv li φ610mm × 31.8mm X65 steel qib specifications.
3, hauv kev tswj hwm kev lag luam, kev sib koom ua ke lub raj phaj (Steelmaking - Nruam Casting - dov phaj - yeeb nkab) yog ib qho qauv, ntau tshaj li cov yeeb nkab tom qab nrog cov kab ntau lawm hauv Nyiv, Is Nrias teb, Tuam Tshoj Baoshan Iron thiab Steel Co., Ltd., Zhangjiagang Shagang Jinzhou pipeline Co., Tangshan Hlau thiab steel Group Co., Ltd. thiab lwm yam.
4, qib high-qib qauv raj nkag mus rau hauv kev ua lag luam. Ib qho teeb meem tseem ceeb ntawm LSAW yeeb nkab kev lag luam nyob rau hauv kev tsim kho cov kab ntau lawm cov cuab yeej teeb tsa yuav tsum yog qhov teeb meem tseem ceeb thaum koj teeb tsa kev teeb tsa yuav tsum tau txiav txim siab ua ntej qhov kev xav tau vuam, xws li preheating ua ntej cov khoom siv vuam, cua sov los yog pov tseg. kauj ruam yog tsim nyog; Nyob rau tib lub sijhawm, maj mam qhia txog lub network thiab kev tswj cov ntaub ntawv.
5, hauv kev lag luam, ntxiv rau cov roj thiab roj, muaj kev thauj mus los slurry; mechanical qauv raj, lawv yuav tsum tau txuas ntxiv mus siv nyob rau hauv lub tshav pob ntawm thermal hwj chim, nuclear fais fab nroj tsuag, hydropower, lub zog, shipbuilding, tshuaj thiab lwm yam kav dej, thiab xyuam xim rau cov khoom diversification Personalise.
6, thiab kev txhim kho los tiv thaiv HIC Resistance rau deformation raj, muaj peev xwm hloov tau thiab txhim khu kev xa cov kua qaub roj yeeb nkab nyob rau hauv cov xwm txheej tsis zoo (xav av, av qeeg, av qeeg) rooj plaub tiv thaiv kev puas tsuaj rau sab nraud.
