LSAW Tubeyog ib tug longitudinally welded steel yeeb nkab tsim siv submerged arc vuam tshuab.
LSAW steel kav yog tus cwj pwm los ntawm longitudinal welds khiav tag nrho ntev ntawm cov yeeb nkab, uas protrude los ntawm sab hauv thiab sab nrauv ntawm cov yeeb nkab.
Qhov zoo ntawm LSAW steel yeeb nkab yog tias nws tuaj yeem muab cov kav dej loj, tuab-walled, thiab cov kav dej siab.

Hauv cov ntsiab lus yooj yim, lubLSAWCov txheej txheem ntau lawm yuav tsum tau curling steel daim hlau rau hauv lub raj zoo thiab tom qab ntawd siv submerged arc vuam los txuas cov npoo ntawm cov hlau phaj ua ke los tsim cov yeeb nkab steel.
Tom ntej no, peb yuav coj koj los ntawm cov kauj ruam tseem ceeb hauv kev tsim cov LSAW steel kav, muab rau koj kom paub meej txog cov txheej txheem.
1. Phaj tshuaj xyuas thiab txiav: Raws li cov qauv kev siv cov yeeb nkab steel thiab qhov yuav tsum tau muaj, cov phaj tsim nyog yuav raug txiav rau qhov ntau thiab tsawg.
2. Ntug milling: Cov txheej txheem ntawm ntug ntawm cov yeeb nkab steel los tsim cov duab tsim nyog rau vuam, xws li V puab.Cov kauj ruam no yog qhov tseem ceeb rau qhov zoo ntawm qhov vuam.
3. kev tsim: Peb lub tuam txhab siv cov txheej txheem JCOE tsim, uas cov hlau phaj yog tsim rau hauv ib qho kev nruam tubular qauv los ntawm rollers thiab xovxwm.
4.Vuam: Nyob rau hauv lub longitudinal seam ntawm cov qauv tubular, submerged arc vuam yog ua los fuse cov npoo ntawm cov hlau phaj los tsim cov yeeb nkab steel.Qhov no yog kauj ruam tseem ceeb tshaj plaws nyob rau hauv tag nrho cov txheej txheem.
5. Kev tshuaj xyuas: Ntau qhov kev tshuaj xyuas, suav nrog 100% kev kuaj tsis muaj kev puas tsuaj thiab kev sim hydrostatic xau ntawm cov kav hlau, xyuas kom meej tias cov khoom tiav tiav raws li cov qauv yuav tsum tau ua.
Hauv cov txheej txheem tsim khoom tiag tiag ntawm LSAW steel kav, ntxiv rau cov txheej txheem tseem ceeb uas tau hais los saum toj no, muaj ntau lwm yam zoo thiab nyuaj.Cov kauj ruam no yuav tsum tau muaj kev tswj xyuas kom meej thiab kev soj ntsuam nruj kom paub tseeb tias cov kav dej zoo LSAW steel uas ua tau raws li cov qauv.
1. Ua tau zoo heev: LSAW steel kav feem ntau siv nyob rau hauv high-temperature thiab high-pressure ua hauj lwm ib puag ncig.Nrog rau cov txheej txheem tsim nyog, cov kav dej no tuaj yeem tswj hwm kev ua tau zoo txawm tias nyob rau hauv huab cua huab cua thiab nyuaj geological tej yam kev mob.
2. Vuam zoo: Hauv kev tsim khoom ntawm LSAW, lubOb-sided submerged arc vuam (DSAW)txheej txheem yog siv.Cov txheej txheem no ua kom ntseeg tau tias cov vuam tau nkag mus tag nrho, yog li ua tiav cov txheej txheem vuam zoo.Lub vuam yog sib xws thiab zoo ib yam, ntxiv dag zog rau tag nrho cov kev ua tau zoo thiab kev ntseeg siab ntawm cov yeeb nkab steel.
3. Loj txoj kab uas hla tuab-walled steel yeeb nkab:
| Cov ntawv luv | Lub npe | Sab nraud | Phab ntsa Thickness |
| SSAW (HSAW, SAWH) | Spiral Submerged Arc Vuam | 200-3500 hli | 5-25 hli |
| LSAW (SAWL) | Longitudinal Submerged Arc Vuam | 350-1500 hli | 8-80 hli |
| ERW | Hluav taws xob Resistance Welded | 20-660 hli | 2-20 hli |
| SMLS | Seamless | 13.1-660 hli | 2-100 hli |
Raws li tuaj yeem pom los ntawm kev sib piv loj ntawm cov khoom saum toj no, LSAW steel kav muaj qhov zoo tshaj plaws hauv kev tsim cov kav dej loj-ntev tuab-walled steel kav, ua tau raws li cov kev xav tau ntawm cov phiaj xwm loj thiab cov ntawv thov kev lag luam.
4. Siv dav: LSAW steel kav yog dav siv nyob rau hauv cov roj thiab roj kis tau tus mob, structural engineering, choj kev tsim kho, thiab lwm yam teb uas yuav tsum tau high-lub zog steel kav vim lawv siab zog thiab kev ua tau zoo heev.

Ntxiv nrog rau cov qauv ntawm cov yeeb nkab steel uas tau teev tseg saum toj no, cov khoom siv thiab cov qauv ntawm cov hlau phaj, xws li SS400, kuj tseem koom nrog kev tsim cov yeeb nkab steel siv cov txheej txheem LSAW.Lawv tsis muaj npe nyob ntawm no.
Sab hauv thiab sab nrauv ntawm LSAW steel kav feem ntau coated kom haum rau qhov chaw ua haujlwm sib txawv.
Cov txheej txheem no tuaj yeem yog cov txheej tiv thaiv ib ntus lossis cov txheej txheem ntev los tiv thaiv corrosion.Hom txheej txheej muaj xws lipleev xim, galvanization, 3 LPE, FBE,TPEP, epoxy coal tar, lwm.
Cov coatings no zoo tiv thaiv cov kav hlau los ntawm corrosion, ncua lawv lub neej kev pab cuam, thiab xyuas kom lawv ruaj khov thiab kev ntseeg siab nyob rau hauv ntau yam kev mob ib puag ncig.
LSAW steel yeeb nkab yog cov khoom siv tseem ceeb.Txhawm rau kom ntseeg tau tias nws txoj kev sib raug zoo hauv kev lag luam hauv lub tebchaws thiab cheeb tsam sib txawv, LSAW steel yeeb nkab yuav tsum tau txais cov ntaub ntawv pov thawj ntau ntxiv thaum importing thiab xa tawm.Cov feem ntau suav nrogAPI 5L ntawv pov thawj,ISO 9001 ntawv pov thawj,ISO 19001 Daim Ntawv Pov Thawj ntawv pov thawj, ISO 14001 ntawv pov thawj,thiab ISO 45001 ntawv pov thawj.
