1. Nqe Lus Nug: ERW yeeb nkab yog dab tsi, thiab nws txawv li cas ntawm seamless lossis LSAW kav?
Teb:ERW stands rau Electric Resistance Welded yeeb nkab. Qhov sib txawv tseem ceeb yog nyob rau hauv cov txheej txheem tsim khoom thiab muaj qhov sib txuas ntawm cov seam. ERW cov kav dej yog tsim los ntawm lub tiaj tus steel sawb (skelp) uas yog txias - ua rau hauv cov duab cylindrical thiab tom qab ntawd dhau los ntawm cov electrodes uas siv high- zaus hluav taws xob tam sim no los ua kom sov cov npoo, uas tom qab ntawd forged ua ke nyob rau hauv siab los tsim ib tug longitudinal weld. Tsis zoo li cov kav dej seamless, uas tsis muaj seam, ERW kav dej muaj qhov sib txawv weld seam. Piv rau LSAW (Longitudinal Submerged Arc Welded) cov kav dej, uas feem ntau yog siv rau cov kab uas loj dua thiab cov phab ntsa tuab uas tsim los ntawm cov txheej txheem UOE, ERW feem ntau yog tus nqi ntau dua - siv tau rau me me mus rau nruab nrab diameters thiab muaj qhov zoo ntawm qhov ntev.
2. Nqe Lus Nug: Dab tsi yog tus qauv kab thiab phab ntsa thickness ranges rau koj ERW steel kav?
Teb:Peb ERW steel yeeb nkab ntau lawm yog ntau yam. Peb feem ntau tsim cov kav dej nrog lub taub sab nraud (OD) xws li 1/2 nti (21.3 hli) txog 24 ntiv (609.6 hli). Txawm li cas los xij, nyob ntawm qhov tshwj xeeb zeb, peb tuaj yeem ua raws li 36 ntiv tes rau cov haujlwm tshwj xeeb. Phab ntsa tuab (WT) tuaj yeem nyob ntawm Teem sijhawm 10 (kwv yees . 2.11 hli) mus txog Teem sijhawm 80 thiab dhau mus, nce mus txog 25.4 hli (1 nti). Peb pom zoo kom sab laj peb cov ntaub ntawv qhia txog kev sib xyaw ua ke, vim tias kev tsim khoom yog nyob ntawm qhov tshwj xeeb D / t piv.
3. Lo lus nug: Dab tsi yog cov qib steel siv rau kev tsim cov kav dej ERW, tshwj xeeb tshaj yog rau kev siv roj thiab roj?
Teb:Rau cov qauv siv dav dav, peb feem ntau siv ASTM A36 lossis ASTM A500 Qib B / C. Rau kev siv cov yeeb nkab kab hauv cov roj thiab roj, peb cov qib thov feem ntau yog API 5L B, X42, X46, X52, X56, X60, thiab X70. Rau txhua yam thiab siab tubing, peb siv ASTM A513 lossis ASTM A178 qib. Peb tseem tuaj yeem muab cov kav dej raws li EN 10219 tus qauv (S235, S355) rau cov khw hauv European.
4. Lo lus nug: Koj puas tuaj yeem piav qhia qhov txawv ntawm ERW thiab HFW (High-Frequency Welding) kav? Puas muaj qhov txawv?
Teb:Qhov no yog ib lo lus nug zoo heev. Thaum feem ntau siv sib hloov hauv kev lag luam, muaj qhov sib txawv me ntsis. ERW (Electric Resistance Welding) yog hom dav dav. HFW (High-Vuam zaus) yog ib hom txheej txheem ERW. Hauv cov mills niaj hnub no, HFW siv 100,000 Hz lossis siab dua yog tus qauv vim tias nws ua rau qhov nqaim Heat Affected Zone (HAZ), muaj zog weld, thiab cov seam huv dua. Yog li, xyaum hais lus, thaum peb xa mus rau "ERW yeeb nkab" hnub no, peb yuav luag ib txwm hais txog "HFW yeeb nkab." Peb cov khoom siv nruj me ntsis siv lub siab - zaus induction vuam txoj kev rau superior zoo.
5. Lo lus nug: Ntev npaum li cas rau ERW kav dej? Koj puas muab qhov ntev ntev lossis ntev ntev?
Teb:Peb muab ob qho tib si. Tus qauv kev coj ua yog muab cov kav dej hauv "Random Lengths," feem ntau yog li ntawm 5 txog 7 meters (kwv yees . 20 ft) lossis 11 txog 13 meters (kwv yees . 40 ft). Txawm li cas los xij, peb nkag siab tag nrho tias qhov project- cov kev cai tshwj xeeb xav tau qhov tseeb. Yog li ntawd, peb tau nruab los muab "Tshaj / Random" ntev, lossis peb tuaj yeem ua tiav qhov kawg- txiav cov kev pabcuam kom ua tau raws li koj qhov ntev npaum li cas (piv txwv li, 6 meters lossis 12 meters raws nraim) raws li koj cov lus qhia.
