1.Ntiaj teb: Dab tsi yog cov txheej txheem tseem ceeb ntawm LSAW Yeeb Nkab? Cov kauj ruam tseem ceeb yog dab tsi?
1.Cov lus teb: Cov txheej txheem tseem ceeb: Hlau strip tshuaj xyuas thiab qib → Kauv txoj kev (dov cov hlau sawb mus rau hauv cov kav raj siv lub tshuab tsim) → Submerged arc welding (ib txhij submerged arc vuam ntawm sab hauv thiab sab nraud welds) → Weld soj ntsuam (UT / RT) → Txoj kab uas hla kev kho (kho qhov siab) welding kev nyuaj siab nyob rau hauv tuab - cov kav dej muaj phab ntsa) → Hydrostatic kuaj → Nto los tiv thaiv - kev kho corrosion → tiav cov khoom kuaj thiab ntim. Cov kauj ruam tseem ceeb: Kauv txoj kev tsim (txiav txim siab cov yeeb nkab txoj kab uas hla thiab vuam lub kaum ntse ntse), submerged arc vuam (txiav txim siab vuam zoo), txoj kab uas hla expansion thiab kho cua sov (optimizing yeeb nkab qhov ntev thiab kev ua tau zoo).
2.Cov lus nug: Dab tsi yog qhov txawv ntawm HFW Yeeb Nkab thiab cov txheej txheem ERW Yeeb Nkab ib txwm?
2.Cov lus teb: Muaj peb qhov sib txawv ntawm qhov tseem ceeb: Ua ntej, qhov vuam fais fab. HFW Yeeb Nkab siv lub siab- zaus induction fais fab mov (10-100kHz), ua rau cua kub ceev (txog 1000℃/ s), thaum cov ERW yeeb nkab ib txwm siv ntau zaus los yog nruab nrab-frequency power sources, ua rau qeeb cua sov. Qhov thib ob, txoj kev tsim. HFW Yeeb Nkab siv txuas ncaj qha- seam forming ua ke nrog ib txhij high-frequency induction cua sov, ua rau muaj kev ua haujlwm siab. Traditional ERW Yeeb Nkab siv segmented forming ua raws li kev vuam, uas tsis tshua muaj txiaj ntsig. Thib peb, weld seam kev kho mob. HFW Yeeb Nkab tso cai rau online weld seam smoothing tom qab vuam, txo qhov roughness. Ib txwm ERW Yeeb Nkab xav tau kev ua haujlwm offline, ua rau tsis txaus siab.
3.Nqe: Dab tsi yog qhov tshwj xeeb ntawm cov txheej txheem electrofusion vuam rau EFW Yeeb Nkab? Yuav ua li cas nws txawv ntawm qhov zoo tib yam welding?
3.Cov lus teb: Qhov tshwj xeeb electrofusion vuam txheej txheem ntawm EFW Yeeb Nkab: Nws siv qhov qis -voltage, siab -tam sim no electrofusion tshav kub qhov chaw los ua kom sov ntawm ntug ntawm cov hlau strip mus rau lub xeev molten, thiab tom qab ntawd ua tiav seamless fusion los ntawm extrusion rollers. Tsis xav tau flux thaum lub sij hawm vuam txheej txheem, thiab lub vuam yog ib tug ntshiab hlau fusion qauv. Qhov sib txawv ntawm qhov zoo tib yam tsis kam vuam (ERW): ERW ncaj qha tshav kub ntawm ntug ntawm cov hlau sawb nrog rau tam sim no, tso siab rau cov cua sov uas tsim los ntawm kev sib cuag rau vuam. Nws yuav tsum tau tswj cov zaus tam sim no thiab lub siab, thiab nws yooj yim rau vuam tsis xws luag vim kev sib cuag tsis zoo. EFW Yeeb Nkab siv cov khoom siv hluav taws xob los tswj qhov loj ntawm lub pas dej molten, uas ua rau lub vuam tsis muaj slag inclusions lossis porosity defects. Lub fusion ceev kuj tseem yog 30% sai dua li cov vuam zoo tib yam, ua rau nws tsim nyog rau cov kav dej precision.
4.Cov lus nug: Yuav ua li cas cov nqi tsim khoom ntawm plaub hom welded kav yuav tsum tau nyob ntawm qhov siab tshaj mus rau qis tshaj? Dab tsi yog qhov tseem ceeb cuam tshuam?
4.Cov lus teb: Cov nqi tsim khoom: LSAW Yeeb Nkab> HFW Yeeb Nkab> EFW Yeeb Nkab> ERW Yeeb Nkab. Yam tseem ceeb cuam tshuam: Ua ntej, cov cuab yeej siv nyiaj txiag. Cov khoom siv kauv, submerged arc vuam cov cuab yeej, thiab cov khoom siv kho cua sov rau LSAW cov kav dej muaj tus nqi siab tshaj plaws, ua raws li qhov siab - cov khoom siv hluav taws xob ntau zaus rau HFW cov kav dej, tom qab ntawd cov khoom siv electrofusion precision rau EFW kav, nrog cov khoom siv ERW cov kav dej ib txwm muaj tus nqi qis tshaj. Thib ob, kev siv hluav taws xob. LSAW yeeb nkab kev kho cua sov thiab submerged arc vuam muaj zog noj. HFW yeeb nkab siab- zaus cua sov siv hluav taws xob tsawg dua li LSAW, EFW yeeb nkab siv zog yog nruab nrab, thiab ERW yeeb nkab zog noj yog qhov qis tshaj. Thib peb, cov khoom poob. Vim yog kev sib sau ua ke, LSAW cov kav dej muaj tus nqi siv steel ntawm kwv yees li 85%, HFW / ERW kav kwv yees li 95%, thiab EFW kav dej kwv yees li 92%, ntxiv cuam tshuam cov nqi.
5.Nqe lus nug: Dab tsi yog qhov sib txawv ntawm cov nqi tsim khoom ntawm LSAW kav, EFW kav, ERW kav, thiab HFW kav? (Nqa DN200, 6mm phab ntsa thickness ua piv txwv)
5.Cov lus teb: Raws li kev lag luam tus nqi nruab nrab hauv xyoo 2026, tus nqi tsev (RMB / meter) ntawm DN200 welded yeeb nkab nrog phab ntsa thickness ntawm 6 hli yog raws li nram no: LSAW Yeeb Nkab: kwv yees li RMB 120-150, feem ntau yog vim tus nqi siab ntawm tuab -cov ntaub ntawv raw khoom thiab kev kho cua sov; HFW Yeeb Nkab: kwv yees li RMB 90-110, nrog rau kev siv hluav taws xob siab ntawm high{11}} cov khoom siv zaus thiab feem ntau ntawm cov nqi ntawm cov khoom siv high-end; EFW Yeeb Nkab: kwv yees li RMB 75-90, nrog me ntsis siab dua raw khoom poob vim yog kev ua tiav; ERW Yeeb Nkab: kwv yees li RMB 60-80, nrog cov khoom siv qis tshaj plaws thiab cov nqi hluav taws xob, muab tus nqi siab tshaj plaws. Qhov sib txawv tseem ceeb yog los ntawm peb yam: kev siv cov khoom siv raw, kev siv hluav taws xob, thiab cov khoom siv depreciation.
