Hauv kev lag luam thoob ntiaj teb cov hlau thiab cov kav dej, xaiv txoj kev tsim cov yeeb nkab zoo tshaj plaws yog qhov kev txiav txim siab tseem ceeb uas cuam tshuam ncaj qha rau kev nyab xeeb, pob nyiaj siv, thiab kev ua haujlwm ntev ntawm kev tsim kho vaj tse. Ntawm ntau hom welded steel raj, peb ua lag luam: Longitudinal Submerged Arc Welded (LSAW steel yeeb nkab), Hluav taws xob Resistance Welded (
ERW steel yeeb nkab), thiab Kauv Submerged Arc Welded (SSAW) yeeb nkab.
Kev nkag siab txog qhov sib txawv ntawm cov qauv, txheej txheem tsim khoom, thiab cov ciam teb sib txawv ntawm cov kav dej no yog qhov tseem ceeb rau cov kws tshaj lij thiab cov neeg tswj xyuas kev yuav khoom thoob ntiaj teb. Raws li ib tug premier thoob ntiaj teb manufacturers,Hebei Huayang Steel Yeeb Nkab Co., Ltd.tshwj xeeb hauv kev tsim sab saum toj -tierLSAW steel yeeb nkabthiab
ERW steel yeeb nkabkev daws teeb meem engineered kom tau raws li qhov nruj tshaj plaws thoob ntiaj teb specifications.
Cov lus qhia ntxaws ntxaws no muab cov lus qhia hauv - qhov tob tob thiab kev sib piv ntawm peb lub raj xa dej no, qhia tias vim li cas LSAW thiab ERW yog qhov kev xaiv zoo tshaj plaws rau kev lag luam tseem ceeb niaj hnub no.
1. Sib sib zog nqus dhia mus rau hauv peb Cov Yeeb Nkab Tsim Tshuab
Txhawm rau nkag siab txog lawv qhov kev ua tau zoo sib txawv, peb yuav tsum ua ntej txheeb xyuas seb txhua hom yeeb nkab yog tsim thiab welded li cas.
Longitudinal Submerged Arc Welded (LSAW steel yeeb nkab)
Ib LSAW steel yeeb nkabyog tsim los siv hnyav, ib daim hlau hlau ua raw khoom. Lub phaj tau dhau los ua qhov txias txias- txheej txheem tsim- xws li JCOE (J-ing, C-ing, O-ing, thiab E-ing) lossis UOE cov txheej txheem- thiab tom qab tau koom nrog ob -sided submerged arc (AWDS). Lub ntsiab yam ntxwv ntawm LSAW yog nws txoj kab ncaj nraim weld seam thiab nws ncej-weld tag nrho txias expansion, uas txo cov kev ntxhov siab sab hauv thiab lav zoo geometric roundness.
Hluav taws xob Resistance Welded (ERW steel yeeb nkab)
IbERW steel yeeb nkabyog tsim los ntawm txias- ua kom kub tsis tu ncua- dov steel coils rau hauv cov duab cylindrical. Tsis zoo li submerged arc vuam, lub longitudinal seam ntawm ib qho
ERW steel yeeb nkabtau koom nrog siv high- zaus hluav taws xob tam sim no ($HFW$). Cov txheej txheem no tsim cov khoom siv- xeev forge weld yam tsis tau ntxiv cov khoom siv hlau. Qhov tshwm sim ntawm seam yog sib xyaw ua ke, sib xws, thiab tshaj tawm -weld heat-kho (PWHT) kom phim cov microstructure ntawm niam txiv hlau phaj.
Kauv Submerged Arc Welded (SSAW) Pipe
SSAW cov kav dej yog tsim los ntawm dov qis- carbon structural steel sawb los yog qis- alloy structural steel sawb rau hauv cov yeeb nkab dawb paug ntawm qee lub kaum sab xis (lub kaum sab xis), thiab tom qab ntawd vuam cov yeeb nkab seam. Txoj kev vuam tseem yog submerged arc vuam, tab sis cov seam khiav spirally nyob ib ncig ntawm lub raj lub cev.
2. Kev sib piv: Vim li cas LSAW thiab ERW ua tau zoo SSAW hauv cov ntawv thov tseem ceeb
Thaum configuring siab -pressure zog pipelines los yog hnyav structural ncej,LSAW steel yeeb nkabthiab
ERW steel yeeb nkabmuab qhov zoo ntawm engineering zoo dua kauv welded kav.
Qauv & Engineering Metrics
* Seam Length: LSAW / ERW (luv, Ncaj) vs. SSAW (Long, kauv)
* Phab ntsa Gages: LSAW (Ultra-Thick, mus txog 50mm+) vs. ERW/SSAW (Thin-Medium)
* Precision: ERW / LSAW (Zoo heev OOR / WT) vs. SSAW (Moderate)
* Kev Nyab Xeeb Kev Nyuaj Siab: LSAW (Lowest ntawm Expansion) vs. SSAW (Hloov Residual)
Weld Seam Length thiab Stress Distribution
Weld seam ntawm ib tug ncaj longitudinal yeeb nkab (LSAW steel yeeb nkabthiab
ERW steel yeeb nkab) yog luv luv dua li ntawm cov kav dej kauv. Ib qho luv luv weld seam ib txwm txo qis qhov tshwm sim ntawm vuam tsis xws luag, suav nrog, lossis micro- tawg. Tsis tas li ntawd, cov kav dej muab kauv muaj ntau ntau- cov kev taw qhia cov kev ntxhov siab nyob rau hauv lawv cov kauv seams, ua rau lawv tsis tshua muaj kev txaus siab rau qhov tsis zoo, siab - ib puag ncig siab.
Dimensional Accuracy thiab Geometric Tolerance
Niaj hnubERW steel yeeb nkabkab xa tawm tshwj xeeb concentricity, uniform phab ntsa thickness, thiab meej txheej kab (OD) tolerances vim tsis tu ncua txias- dov. Ib yam li ntawd, mechanical txias expansion theem nyob rau hauv
LSAW steel yeeb nkabkev tsim khoom kom ntseeg tau tias tsawg heev tawm - ntawm - roundness (OOR). Qhov kev ua tau zoo no ua kom yooj yim dua, kev nyab xeeb ntawm kev sib tw thiab vuam piv rau SSAW lwm txoj hauv kev.
Phab ntsa Thickness thiab loj txoj kab uas hla
Thaum ERW steel yeeb nkab yog tus nqi tshwj xeeb -zoo rau me me- mus rau - nruab nrab diameters thiab txheem phab ntsa ntsuas,
LSAW steel yeeb nkabyuav siv sij hawm dhau rau qhov hnyav heev - lub luag haujlwm xav tau. LSAW thev naus laus zis tuaj yeem siv zog ua haujlwm sab nraud ntawm 16 mus rau 60 ntiv tes thiab phab ntsa tuab tshaj 50 hli - muaj peev xwm ua kom cov kauj txuas txuas ntxiv -raws li cov kav dej (ERW thiab SSAW) tsuas tuaj yeem ncav cuag.
