1.Nqe lus nug: Cov ntsiab lus tseem ceeb ntawm LSAW Pipe, EFW Pipe, ERW Pipe, thiab HFW Pipe yog dab tsi? Lawv lub npe lus Askiv thiab Suav yog dab tsi?
1.Cov lus teb: LSAW Yeeb Nkab yog cov ntawv luv rau Longitudinal Submerged Arc Welded Yeeb Nkab, uas koom nrog kev sib sau ua ke ntawm steel sawb rau hauv cov tubular zoo ua ntej submerged arc vuam. EFW Yeeb Nkab yog ib qho luv luv rau Hluav Taws Xob Fusion Welded Yeeb Nkab, uas siv cov tshuab electrofusion vuam los tsim cov vuam seam thiab yog sub- hom siab - zaus welding. ERW Yeeb Nkab yog cov ntawv luv rau Cov Hluav Taws Xob Hluav Taws Xob Welded Yeeb Nkab, uas siv hluav taws xob tam sim no los ua kom sov cov npoo ntawm cov hlau sawb thiab siv lub siab rau vuam; Nws yog ib lub ntsiab lus dav dav rau cov txheej txheem welding. HFW Yeeb Nkab yog cov ntawv luv rau High Frequency Welded Yeeb Nkab, uas siv siab - zaus tam sim no (feem ntau siab dua 10kHz) kom ceev cov npoo ntawm cov hlau sawb mus rau lub xeev molten, ces extrudes thiab welds nws. Nws yog qhov siv dav tshaj plaws siab - hom zaus ntawm ERW txheej txheem (hauv kev lag luam tiag tiag, HFW feem ntau suav tias yog siab-kawg sub- hom ERW, nrog kev ua haujlwm zoo dua vuam thiab vuam seam precision).
2.Cov lus nug: Dab tsi yog qhov sib txawv hauv cov txheej txheem ntawm plaub hom welded kav?
2.Cov lus teb: Qhov sib txawv tseem ceeb nyob rau hauv txoj kev tsim: LSAW Yeeb Nkab siv kauv sib sau, nrog rau cov hlau sawb dov ntawm lub kaum sab xis, ua rau cov hlua khi hlua khi. Txoj kev no tuaj yeem tsim cov kav loj - txoj kab uas hla, tuab - cov kav dej. EFW Yeeb Nkab, HFW Yeeb Nkab, thiab ERW Yeeb Nkab tag nrho siv ncaj- seam forming, nrog rau tib lub pob tw pob qij txha ntawm cov hlau strip npoo, uas ua rau lub vuam seam ncaj nraim. EFW Yeeb Nkab Electrofusion Vuam qhia txog qhov zoo ntawm kev sib txuas, thaum HFW Yeeb Nkab cia siab rau cov cua kub ceev nrog siab - zaus tam sim no, ua rau nws nrawm dua li cov yeeb nkab ERW. ERW Yeeb Nkab, ntawm qhov tod tes, npog qis - mus rau nruab nrab -frequency resistance welding, muab ntau yam kev siv.
3.Question: Raws li weld seam morphology, mus rau qeb ntawm welded yeeb nkab ua LSAW Yeeb Nkab, EFW Yeeb Nkab, thiab ERW / HFW Yeeb Nkab?
3.Cov lus teb: LSAW yeeb nkab yog ib hom kauv welded yeeb nkab, nrog lub vuam seam tsim ib lub kaum ntse ntse (feem ntau 15℃-59 degree) nrog cov yeeb nkab axis. EFW yeeb nkab, ERW yeeb nkab, thiab HFW yeeb nkab yog txhua qhov ncaj seam welded kav, nrog cov vuam seam sib npaug rau cov yeeb nkab axis. Ntawm lawv, HFW yeeb nkab, raws li hom high-end ntawm ERW, ua pov thawj superior precision thiab sib xws nyob rau hauv ncaj seam txoj kev.
4.Cov lus nug: Yuav ua li cas cov khoom siv ntawm plaub hom welded kav yuav tsum tau nyob ntawm qhov siab tshaj mus rau qis tshaj? Vim li cas?
4.Cov lus teb: Qhov kev ua tau zoo tshaj plaws yog: HFW yeeb nkab > ERW yeeb nkab > EFW yeeb nkab > LSAW yeeb nkab. Lub laj thawj tseem ceeb yog qhov sib txawv ntawm kev sib sau thiab vuam sib dhos: HFW kav dej siv siab - zaus cua sov ceev + nruam ncaj seam tsim, ua tiav vuam ceev ntawm 30-60 m / min, ua rau lawv yog hom zoo tshaj plaws; Cov kav dej ERW ib txwm muaj qis dua vuam nrawm dua li HFW (feem ntau 15-40 m / min); EFW cov kav dej, nrog rau lawv cov txheej txheem electrofusion vuam uas yuav tsum tau muaj kev tswj xyuas siab tshaj qhov vuam vuam, muaj qhov nrawm ntawm ERW thiab LSAW; LSAW kav yuav tsum tau muab kauv sib sau, thiab tuab-walled kav yuav tsum tau tom qab kev kho cua sov tom qab vuam, uas ua rau ib tug ntev ntau lawm voj voog ntawm ib tug yeeb nkab thiab lub qeeb ceev (feem ntau 5-15 m / min).
5.Nqe lus nug: Dab tsi yog qhov sib txawv ntawm cov yeeb nkab txoj kab uas hla ntawm LSAW, EFW, ERW, thiab HFW kav?
5.Cov lus teb: LSAW cov kav dej muaj qhov dav dav tshaj plaws, npog cov kab loj ntawm DN400 mus rau DN3000, thiab qhov loj dua; HFW thiab ERW kav tsuas yog rau me me thiab nruab nrab txoj kab uas hla, nrog rau tus qauv ntau ntawm DN15-DN600, thiab qee cov kab ntau lawm tuaj yeem txuas mus rau DN800; EFW kav dej muaj ib tug nqaim txoj kab uas hla, concentrated nyob rau hauv nruab nrab txoj kab uas hla ntawm DN50-DN400, thiab yog haum rau precision yeeb nkab xav tau.
