Vim tias kev thauj mus los hauv cov kav dej yog qhov tshwj xeeb rau kev thauj cov roj, roj, yog li ntawd, cov kav dej hauv cov roj av thiab cov roj av tau siv dav.Yav dhau los petrifaction Corporation txhua xyoo cov roj crude 120000000 T, feem ntau siv los ntawm cov kav dej;txhua xyoo kev tsim cov chav, thee, diesel 5000 lab tons, ntawm 80% nrog cov kav xa dej;petrochemical enterprise ntaus ntawv, ntaus ntawv ntawm cov kua los yog gaseous tshuaj cov ntaub ntawv kev thauj mus los yog tsuas yog los ntawm cov raj xa dej kom tiav.Yog li ntawd, petrochemical kev lag luam txhua xyoo peev kev tsim kho thiab hauv kev tsim khoom thiab kho txhua yam yuav tsum tau siv ntau cov yeeb nkab steel.Tab sis, vim hais tias ntawm petrochemical kev lag luam kev ua hauj lwm yog yus muaj los ntawm kev kub thiab siab siab, flammable thiab explosives, yog li ntawd rau kev siv ntawm steel hlab yuav tsum nruj heev.

Ncaj tsis kamwelding steel yeeb nkabkev loj hlob

Nyob rau hauv xyoo tas los no, muaj lub thoob ntiaj teb zoo seamless steel yeeb nkab los hloov tus nqi siab txoj kev loj hlob qauv, feem ntau yog vim welded yeeb nkab ntau lawm technology lossi breakthrough, manifested nyob rau hauv cov nram qab no yam:

(1) desulfurization tshuab, kom cov sulfur cov ntsiab lus ntawm cov hlau raug txo, txhim kho cov vuam zoo ntawm cov yeeb nkab steel.

(2) lub tshuab nqus tsev degassing tshuab, txhim kho lub raj dawb paug steel purity, txo cov kev suav nrog, qhov vuam seam zoo txhim kho.

(3) vim qhov sib ntxiv ntawm V, Ti, Nb thiab lwm yam tshwj xeeb, txo cov pa roj carbon sib npaug, steel toughness, lub zog thiab lwm yam khoom zoo tuaj.

(4) kev txhim kho ntawm sawb steel kub dov tshuab, nce qhov tseeb qhov tseeb, yog li cov yeeb nkab loj sib txawv yuav txo tau.

(5) kev txhim kho cov kev soj ntsuam zoo, xws li kev kuaj ultrasonic nondestructive, hydrostatic kuaj tshuab thiab lwm yam khoom siv yuav tsum tau siv, los xyuas kom meej qhov zoo ntawm cov khoom kawg.

Ncaj tsis kam vuam steel yeeb nkab siv hauv kev lag luam petrochemical

Petrochemical kev lag luam xaiv cov yeeb nkab steel vim dais lub siab, feem ntau siv hauv cov kua dej nrog seamless steel yeeb nkab.Hluav taws xob tsis kam welded yeeb nkab thiab cov kua dej nrog seamless steel yeeb nkab sib piv, muaj cov txiaj ntsig kev lag luam, feem ntau qhia hauv: tsawg peev;mechanization, automation degree yog siab;kev siv hluav taws xob tsawg (chav kub sib sau, thiab seamless steel yeeb nkab rau cua sov lossis txias kos duab molding);tus nqi ntau lawm yog tsawg, rau seamless steel raj yog li 2\/3;nruam ntau lawm, productivity siab yield thiab siab.Longitudinal welded yeeb nkab kev lag luam nyob rau hauv Tuam Tshoj pib nyob rau hauv lub 50′s, pib lig, cov txheej txheem ntau lawm thiab technology thiab tsim lub teb chaws yog muab piv, muab nyob rau hauv sib txawv loj heev.Feem ntau ntawm kev lag luam cov cuab yeej siv tshuab tsis ua haujlwm, tsis muaj qhov tsim nyog ntawm kev tshawb nrhiav, tab sis kuj ua rau qhov tsis zoo ntawm txoj siv luv luv, nqaim li raw khoom, ua rau cov khoom siv welded yeeb nkab nrog me me aperture, tsis tshua muaj peev xwm, cov khoom tsim tsis tsim nyog, welded yeeb nkab ntau lawm nyob rau hauv 80% tsuas yog siv raws li ib tug tsis tshua muaj siab kua conveying thee dej yeeb nkab, txhua yam ntawm tshwj xeeb yeeb nkab uas tsis muaj feem.Qhov no zoo ntawm cov khoom siv vuam qis thiab qib thev naus laus zis, ua rau
