ERW, SSAW thiab LSAW yog peb qhov kev tsim khoom tseem ceeb rau cov kav hlau welded, txhua tus muaj nws tus kheej lub zog hauv kev lag luam xws li roj thiab roj tsheb thauj mus los thiab kev tsim kho hauv nroog. Cov lus hauv qab no tuaj yeem pab koj nkag siab qhov sib txawv tseem ceeb ntawm lawv.
| Yam ntxwv | ERW (Ncaj Seam siab-frequency Resistance Welded Pipe), | SSAW (kauv submerged Arc Welded yeeb nkab) | LSAW (Straight Seam Submerged Arc Welded Pipe) |
| Cov txheej txheem tseem ceeb | Siab - zaus tam sim no heats ntug ntawm lub raj khoob thiab ces extrudes thiab welds nws | Hlau strips txuas ntxiv dov ntawm ib qho helix Lub kaum sab xis thiab welded los ntawm submerged arc vuam ntawm ob sab | Ib daim hlau hlau yog nias rau hauv cov duab, thiab muab ob npaug rau -sab submerged arc vuam yog saws thiab txoj kab uas hla tau nthuav dav |

| Qhov txiaj ntsig loj |
Lub weld seam yog luv luv, nrog qhov siab qhov tseeb, cov phab ntsa tuab tuab thiab zoo nto zoo |
Tib qhov tshwj xeeb ntawm steel sawb yog siv los tsim ntau yam yeeb nkab diameters nrog cov khoom siv siab.

Weld zoo yog qhov zoo tshaj plaws, nrog lub siab muaj zog -cov kabmob muaj peev xwm thiab qhov tseeb geometric qhov ntev |
| Cov kev txwv loj |
Peb tsuas tuaj yeem tsim nyias- cov kav dej ntawm qhov nruab nrab thiab me me, thiab tej zaum yuav muaj qhov tsis xws luag hauv thaj chaw vuam |
Lub weld seam yog ntev thiab yooj yim rau vuam tsis xws luag, nrog cov tsis zoo geometric dimensional raug. | Cov nqi ntau lawm thiab cov cuab yeej siv loj loj |
| Tej daim ntawv thov |
Cov me me thiab nruab nrab- cov kav dej loj loj rau cov pa hauv nroog, cov roj av thiab cov khoom siv roj ua kom zoo, thiab lwm yam |
Kev siv dej hauv nroog, cua sov tes hauj lwm, qis- kev thauj mus los ntawm cov dej siab, thiab lwm yam. | Cov cheeb tsam tseem ceeb xws li ntev - nrug siab - cov kav dej siab thiab cov pa roj, thaj chaw txias, thiab cov kav dej hauv qab |
💡 Xaiv cov yeeb nkab steel raws li qhov xav tau
Tom qab nkag siab lawv qhov sib txawv, hauv cov haujlwm tiag tiag, koj tuaj yeem ntsuas thiab xaiv los ntawm cov hauv qab no:
• Yeeb nkab txoj kab uas hla thiab phab ntsa thickness:
Thaum loj - txoj kab uas hla thiab tuab - cov kav dej yog xav tau, qhov kev xaiv tseem ceeb ntawm SSAW thiab LSAW. Yog tias qhov kev xav tau siab heev tau muab tso rau ntawm qhov siab thiab kev nyab xeeb, LSAW yuav tsum raug xaiv. Yog tias siv rau hauv cov xwm txheej uas tsis tshua muaj siab xws li cov kua dej thiab qhov cua, SSAW muaj qhov zoo dua tus nqi. Rau txoj kab nruab nrab thiab me me thiab nyias - cov kav dej, ERW yog qhov kev xaiv zoo thiab kev lag luam.
• Conveyed nruab nrab thiab siab:
Thaum xa khoom siab -siab, flammable, explosive los yog toxic media (xws li natural gas, crude oil), tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas nyuaj rau tswj, LSAW nrog lub siab tshaj plaws weld zoo yuav tsum tau muab qhov tseem ceeb. Rau qis - cov kua dej siab xws li dej thiab cua, SSAW thiab ERW tuaj yeem ua tau raws li qhov yuav tsum tau ua.
• Tus nqi thiab qhov project pob nyiaj siv:
Raws li lub hauv paus ntawm kev ua raws li cov kev cai, ERW feem ntau muaj cov nqi zoo tshaj plaws, ua raws li SSAW, thiab LSAW muaj peev txheej siab tshaj plaws.
• Chaw nyob thiab ib puag ncig:
Rau cov cheeb tsam dhau los ntawm Chav Kawm 1 thiab Chav Kawm 2 xws li qhov siab- thaj chaw siab txias, thaj chaw hauv qab dej lossis thaj chaw muaj neeg nyob, cov qauv tsim feem ntau qhia txog kev siv LSAW.
