Hluav taws xob Resistance Welded kav yog dav siv nyob rau hauv niaj hnub industrial piping systems vim lawv ruaj khov qhov tseeb, cov txheej txheem ntau lawm, thiab zoo ib yam weld zoo. Piv nrog rau lwm yam welded yeeb nkab hom, ERW kav dej tuav ib qho tseem ceeb nyob rau hauv me me thiab nruab nrab txoj kab uas hla carbon steel yeeb nkab lag luam. Lawv qhov loj me, lub peev xwm ntawm phab ntsa tuab, thiab cov yam ntxwv ntawm vuam seam ua rau lawv haum rau kev sib kis ntawm cov dej, kev tsim vaj tsev, kev tsim kho tshuab, thiab cov khoom siv hluav taws xob.
Kev nkag siab txog qhov tsis sib xws thiab cov yam ntxwv ntawm cov kav dej ERW yog qhov tseem ceeb rau cov kws tshaj lij thiab cov kws tshaj lij kev muag khoom. Tsis zoo li sab nraud txoj kab uas hla, phab ntsa thickness, roundness kam rau ua, thiab weld seam configuration ncaj qha cuam tshuam rau pipeline kev ua tau zoo, installation efficiency, thiab kev pab lub neej.
Dimensional Range ntawmERW Carbon Steel Yeeb Nkab
Sab nraum txoj kab uas hla
Sab nraud txoj kab uas hla ntawm ERW carbon steel kav yog txiav txim siab feem ntau los ntawm cov khoom tsim thiab sawb steel dav siv thaum tsim khoom. Hauv cov kab ntau lawm, ERW cov kav dej npog ib txoj kab uas hla ntawm kwv yees li 21.3 hli mus txog 660 hli. Cov kab me me feem ntau yog siv rau hauv cov khoom siv kho tshuab, cov kav dej, thiab cov kav dej hauv tsev, thaum cov kab nruab nrab yog dav siv hauv cov roj thiab roj tsheb thauj mus los thiab cov kav dej sib txuas.
Nyob rau hauv cov txheej txheem thoob ntiaj teb cov kav dej xws li API 5L thiab ASTM A53, ERW kav dej feem ntau yog muab rau hauv cov yeeb nkab nominal qhov ntau thiab tsawg los ntawm NPS 1/2 txog NPS 24. Qhov no suav nrog feem ntau ntawm cov ntawv thov kev lag luam uas yuav tsum tau muaj kev kub siab thiab kev tswj kom zoo ib yam.
Qhov kom zoo dua ntawm ERW cov kav dej hauv cov kab no nyob rau hauv lawv cov kev ua haujlwm siab thiab cov phab ntsa tuab kuj zoo sib xws piv nrog qee cov kav welded kav.
Phab ntsa Thickness Muaj peev xwm
Phab ntsa thickness yog lwm qhov tseem ceeb ntawm qhov ntsuas qhov cuam tshuam rau lub siab ua haujlwm thiab lub zog ntawm cov qauv. ERW yeeb nkab phab ntsa thickness feem ntau yog tsim los ntawm kwv yees li 2.0 hli mus rau ib ncig ntawm 20 hli nyob ntawm txoj kab uas hla thiab tsim muaj peev xwm ntawm cov kab ntau lawm.
Rau nyias- cov kav dej phab ntsa siv hauv cov khoom siv kho tshuab thiab cov kev pabcuam hauv tsev, thickness yuav qis dua 4 hli. Nyob rau hauv cov roj thiab cov kav xa hluav taws xob, cov phab ntsa tuab ntawm 8 hli thiab 16 hli feem ntau tau teev tseg kom ntseeg tau tias muaj peev xwm txaus thiab kev nyab xeeb.
Kev sib raug zoo ntawm txoj kab uas hla thiab phab ntsa tuab yuav tsum ua raws li cov qauv txheej txheem xws li cov sij hawm sib cais lossis teev cov kev zam rau zeb. Cov lus hauv qab no qhia txog qhov dav dav dav rau ERW kav dej.
| Parameter | Hom kab mob | Kev thov Sector |
|---|---|---|
| Sab nraud txoj kab uas hla | 21.3 hli - 660 hli | Industrial pipelines, kev tsim kho |
| Phab ntsa Thickness | 2.0mm-20 hli | Kev tsim qauv thiab kev pabcuam siab |
| Nominal Pipe Loj | NPS 1/2 – NPS 24 | Roj, roj, xa dej |
| Ntev | 6 m - 12 m txheem | Pipeline installation |
Cov qhov loj me no qhia tau tias yog vim li cas ERW kav dej ua lag luam nyob nruab nrab thiab me me.
Cov yam ntxwv ntawm tus yam ntxwv ntawmERW Cov kav dej
Weld Seam Tsim
Lub ntsiab lus tseem ceeb ntawm ERW cov kav dej yog qhov ntev ntawm vuam seam tsim los ntawm siab - zaus hluav taws xob tsis kam vuam. Thaum lub sij hawm tsim khoom, ib tug hlau sawb yog nce mus rau hauv ib tug cylindrical zoo. High- zaus tam sim no dhau ntawm cov npoo ntawm cov sawb, ua kom muaj cua sov vim hluav taws xob tsis kam. Thaum cov npoo rhuab raug nias ua ke los ntawm nyem cov menyuam, ib qho khoom siv - xeev weld seam yog tsim.
Tsis zoo li arc vuam txheej txheem siv nyob rau hauv lwm yam yeeb nkab hom, ERW vuam tsis xav tau ntxiv muab tub lim hlau. Qhov tshwm sim weld seam yog nqaim thiab zoo ib yam, nrog rau qhov kub me me - thaj tsam cuam tshuam. Qhov no pab txhawb kom ruaj khov mechanical zog raws lub cev yeeb nkab.
Niaj hnub nimno ERW manufacturing kab kuj muaj xws li hauv internet weld seam soj ntsuam tshuab xws li ultrasonic los yog eddy kev kuaj tam sim no los xyuas kom meej weld kev ncaj ncees.
Roundness thiab Dimensional Control
Roundness yog ib qho tseem ceeb parameter rau pipeline sib dhos thiab kev siv cov txheej txheem. Vim tias ERW cov kav dej tau tsim los ntawm cov hlau tsis tu ncua uas siv ntau txoj kev sib tw, cov kav dej feem ntau pom muaj qhov zoo sib xws thiab qhov sib xws.
Lub roundness kam rau ua yog feem ntau tswj nyob rau hauv li ntawm 0.5 feem pua ntawm lub nominal sab nraud txoj kab uas hla nyob ntawm seb tus qauv siv thiab cov yeeb nkab loj. Qhov sib npaug sib npaug tso cai rau kev sib txuas yooj yim dua thaum lub sijhawm teeb tsa cov kav dej thiab txhim kho cov khoom xa tawm hauv cov qauv txheej txheem.
Precision sizing units ntawm qhov kawg ntawm txoj kab sib txuas ntxiv refine cov yeeb nkab txoj kab uas hla thiab roundness ua ntej txiav thiab ua tiav cov haujlwm. Qhov kev tswj xyuas qhov ntsuas no yog ib qho ntawm cov laj thawj ERW cov kav dej tau siv dav hauv kev tsim vaj tsev thiab kev tsim khoom siv tshuab.Piv nrog LSAW thiab SSAW Pipes
Txoj kab uas hla muaj peev xwm sib txawv
Thaum ERW kav kav khw me thiab nruab nrab txoj kab uas hla, lwm yam welded yeeb nkab hom xws li longitudinal submerged arc welded kav thiab muab kauv submerged arc welded kav yuav tsum tau loj txoj kab uas hla.
LSAW yeeb nkab feem ntau yog tsim los ntawm steel phaj es tsis yog sawb, tso cai rau zus tau tej cov diameters loj, feem ntau yog li ntawm kwv yees li 406 hli mus rau 1422 hli los yog loj dua rau tej yaam num tshwj xeeb.
SSAW yeeb nkab tuaj yeem ncav cuag ntau dua diameters vim nws txoj kev muab kauv. Los ntawm kev kho lub kaum sab xis, SSAW cov kav dej tuaj yeem ua tau nyob rau hauv txoj kab uas hla tshaj 2000 hli, ua rau lawv haum rau cov kav dej loj loj thiab cov qauv hauv ntug dej hiav txwv.
Phab ntsa Thickness sib txawv
Phab ntsa thickness muaj peev xwm kuj txawv ntawm cov yeeb nkab hom. Vim tias cov kav dej LSAW yog tsim los ntawm cov phaj tuab tuab, lawv cov phab ntsa tuab tuaj yeem tshaj 40 hli rau siab - cov kav xa dej siab. SSAW kav feem ntau txhawb phab ntsa thickness ntawm 6 hli thiab 25 hli nyob ntawm daim ntawv thov.
ERW kav, nyob rau hauv sib piv, feem ntau nyob twj ywm nyob rau hauv nruab nrab thickness ntau vim hais tias ntawm txoj kev strips txwv. Cov lus hauv qab no qhia txog qhov sib txawv ntawm qhov sib txawv.
| Hom yeeb nkab | Hom kab uas hla | Hom Phab Ntsa Thickness | Kev tsim khoom siv |
|---|---|---|---|
| ERW | 21.3-660 hli | 2-20 hli | Hlau strip |
| LSAW | 406-1422 hli | 8-40 hli | Hlau phaj |
| SSAW | 219-2500 hli | 6-25 hli | Hlau kauj |
Qhov kev sib piv no qhia tau hais tias yuav ua li cas txhua txoj kev tsim khoom lag luam tsom mus rau qhov sib txawv ntawm cov raj xa dej.
Engineering Advantages ntawm ERW Pipes
Vim lawv qhov loj me me thiab qhov sib txawv me me weld seam, ERW kav dej tau zoo haum rau cov ntawv thov uas tsis sib xws geometry thiab kev ua haujlwm zoo ib yam yog qhov tseem ceeb. Kev lag luam xws li kev tsim kho, kev faib roj thiab roj, kev thauj mus los hauv dej, thiab kev siv tshuab siv hluav taws xob muaj kev vam khom rau cov kav dej ERW rau cov laj thawj no.
Cov txheej txheem tsim tau zoo kuj ua rau cov nqi tsim khoom sib tw thiab kev xa khoom luv luv piv nrog qee cov phaj hnyav welded kav. Hauv ntau lub raj xa dej, ERW cov kav dej muab qhov zoo sib npaug ntawm cov qauv kev ntseeg tau thiab kev ua haujlwm ntawm kev lag luam.
Xaus
ERW carbon steel kav muaj qhov zoo- qhov sib npaug ntawm qhov sib npaug thiab cov qauv kev ruaj ntseg rau ntau daim ntawv thov kev lag luam. Lawv sab nraud txoj kab uas hla feem ntau yog li ntawm 21.3 hli mus rau 660 hli nrog phab ntsa tuab ntawm 2 hli thiab 20 hli, ua rau lawv zoo tagnrho rau cov kav dej me me thiab nruab nrab. High- zaus vuam tshuab ua kom qhov nqaim thiab txhim khu kev qha longitudinal seam, thaum cov cuab yeej sib sau ua ke tswj xyuas qhov zoo sib xws thiab qhov tseeb.
Piv nrog LSAW thiab SSAW kav, ERW kav dej tsom rau kev ua tau zoo thiab qhov tseeb nyob rau hauv qhov nruab nrab txoj kab uas hla, thaum lwm txoj kev vuam ua rau cov kav dej loj thiab tuab dua. Los ntawm kev nkag siab txog qhov sib txawv ntawm qhov sib txawv thiab cov qauv tsim, cov kws tsim qauv tuaj yeem xaiv cov yeeb nkab uas tsim nyog tshaj plaws rau cov haujlwm tshwj xeeb engineering thiab cov haujlwm ua haujlwm.
