Qhov sib txawv ntawm ERW thiab SAW steel yeeb nkab

ERW yog hluav taws xob tiv thaiv welded steel yeeb nkab, Resistance welded steel yeeb nkab tau muab faib ua kev sib pauv ntawm cov yeeb nkab steel thiab DC welded steel yeeb nkab hauv ob hom.

 

AC vuam nyob rau hauv raws li qhov sib txawv frequencies muab faib ua tsawg zaus vuam, IF vuam, vuam ntawm ultra-IF thiab high-frequency vuam.High-frequency welding yog tsuas yog siv rau zus tau tej cov nyias-walled steel yeeb nkab los yog phab ntsa thickness steel yeeb nkab, siab zaus vuam rau hauv kev sib cuag vuam thiab induction vuam.DC vuam feem ntau yog siv rau cov yeeb nkab me me.Yog li, nyob rau hauv cov nqe lus ntawm kev qhia, high-frequency welded yeeb nkab nrog rau ERW yeeb nkab yog ib tug high-frequency vuam txheej txheem los tsim ERW kav.ERW Longitudinal advanced cov khoom ua tau zoo nyob rau hauv kev lag luam roj thiab roj cia thiab kev thauj mus los, kev coj noj coj ua zoo, kev lag luam steel yeeb nkab ntau dua.

 

Pom cov kav hlau steel yog luv ntawm submerged arc vuam steel yeeb nkab, cov txheej txheem ua rau cov txheej txheem zoo heev, cov txheej txheem flux kom tiv thaiv kom tsis txhob muaj cua sov, thiab muaj cov vuam cheeb tsam.Submerged arc weld ntawm cov khoom zoo, kev ua haujlwm siab, arc thiab haus luam yeeb ob peb yam ntxwv ntawm submerged arc welded yeeb nkab yog dav siv nyob rau hauv siab hlab ntsha, yeeb nkab manufacturing, kab teeb, tsis tshua muaj siab kua, steel ua hauj lwm.Cov khoom tseem ceeb ntawm SAW steel kav LSAW Steel Pipe, Longitudinally Submerged Arc Vuam Hlau Yeeb Nkab LSAW steel yeeb nkab, nws yog kev siv submerged arc vuam ntau lawm ntawm ncaj seam steel yeeb nkab.

 

Qhov sib txawv ntawm erw thiab saw steel yeeb nkab

 

Raws li ERW steel yeeb nkab thiab SAW steel yeeb nkab nyob rau hauv cov yeeb nkab thaum lub sij hawm tsim, vuam thiab txheej txheem yog txawv, yog li ntawd ob hom steel yeeb nkab nyob rau hauv kev ua tau zoo muaj qee qhov sib txawv.

 

(1) ERW steel yeeb nkab nto zoo yog qhov zoo tshaj rau kauv submerged arc welded yeeb nkab, ERW steel yeeb nkab nto yog du, du, zoo nkauj, SAW steel yeeb nkab sab hauv thiab sab nraud weld reinforcement.

 

(2) ERW steel yeeb nkab weld defect hom yog tsawg dua qhov pom steel yeeb nkab.Pom cov yeeb nkab steel nrog cov kuab tshuaj tso, ntau hom kev tsis xws luag, ntxiv rau qhov ntim tsis xws luag, muaj cov hlau-kab ntxiab.ERW steel yeeb nkab weld tsis xws luag tsuas yog xaim-kab thiab ncaj welds, cov txheej txheem tshuaj xyuas yooj yim ua raws, thiab qhov tsis xws luag hauv qhov siab tshaj plaws ntawm kev xav ntawm, ib zaug tsis muaj implicit, ultrasonic xav txog qhov muaj zog, yooj yim rau kev ntes.

 

(3) ERW steel yeeb nkab ntsig txog pom steel yeeb nkab nyob rau hauv seem kev ntxhov siab piv yog tsawg.Txij li thaum ERW yeeb nkab deformation nyob rau hauv cov txheej txheem deformation ntau dua, ua ke tom qab sizing tiaj oval, elliptical ntsug hloov thiab caj dab, ua rau ERW yeeb nkab residual kev ntxhov siab ua me.Kev kuaj lub cev tau pom tias tib yam kev qhia tshwj xeeb, tib yam khoom siv ERW yeeb nkab tom qab incision raws cov axis, cov axial thiab transverse incisions me me txav dua li cov kauv submerged arc welded yeeb nkab.

 

(4) ERW Yeeb Nkab tag nrho kev ua tau zoo ntawm tib yam, thaum cov yeeb nkab ua tsis zoo, steel seem txiav txim siab, tso cai rau vuam.SAW steel yeeb nkab tso cai, thiab cov yeeb nkab vuam kev ua tau zoo thiab kev ua tau zoo tag nrho yog qhov tsis sib xws, vuam qhov chaw muaj kev ntxhov siab corrosion tawg.Cov kev sim qhia tau hais tias kev nyuaj siab corrosion qaug zog kuaj ERW yeeb nkab kauv submerged arc welded yeeb nkab ntev tshaj lub neej.
