Hluav taws xob Resistance Welded (ERW) steel kav, tseem hu ua siab - zaus hluav taws xob tsis kam welded ncaj seam steel kav, yog ib hom khoom siv dav siv welded steel yeeb nkab khoom. Nrog rau qhov zoo xws li qhov siab qhov tseeb, ruaj khov weld zoo, thiab kev ua haujlwm siab, ERW steel kav tau siv dav hauv cov kav dej hauv nroog, kev tsim vaj tsev, kev tsim khoom, roj thiab roj tsheb thauj mus los, thiab lwm yam. Txawm li cas los xij, hauv kev yuav khoom tiag tiag, ERW steel kav los ntawm cov tuam txhab sib txawv thiab nrog cov txheej txheem sib txawv tseem muaj qhov sib txawv ntawm qhov zoo thiab kev siv tau. Yuav ua li cas rau kev tshawb fawb xaiv ERW steel kav yog qhov teeb meem tseem ceeb uas cov koom haum engineering thiab cov neeg yuav khoom yuav tsum tsom rau.
Kab lus no tau txheeb xyuas cov ntsiab lus tseem ceeb ntawm ERW steel yeeb nkab xaiv raws li kev siv engineering.
1. Qhia meej txog Engineering Lub Hom Phiaj ua thawj kauj ruam
Ua ntej yuav ERW steel kav, nws yog ib qho tsim nyog yuav tsum xub txheeb xyuas cov kev pabcuam tshwj xeeb ntawm cov kav dej. Cov hom phiaj sib txawv muaj cov ntsiab lus sib txawv rau cov yeeb nkab ua haujlwm, piv txwv li:
Rau kev siv dej, dej ntws, lossis kev sib kis ntawm cov kua dej dav dav, kev saib xyuas ntau dua yog them rau qhov ruaj khov ntawm qhov ntev thiab weld compactness.
Rau cov txheej txheem los yog kev txhawb nqa lub hom phiaj, lub hom phiaj yog nyob rau ntawm lub zog tawm los thiab tag nrho rigidity.
Rau cov roj, roj, lossis kev thauj mus los nruab nrab, siab-cov kabmob muaj peev xwm thiab vuam seam kev cia siab yuav tsum yog qhov tseem ceeb.
ERW steel kav yog feem ntau haum rau nruab nrab - txoj kab uas hla me me, txuas ntxiv - qhov project ntev uas yuav tsum tau muaj qhov sib xws. Kev nthuav qhia lub hom phiaj pab txhawb qhov tsim nyog xaiv ntawm qib steel, phab ntsa tuab, thiab cov qauv ua tiav hauv cov kauj ruam tom ntej.
2. Tsim nyog xaiv cov qauv ua tiav thiab qib steel
ERW steel kav tuaj yeem siv ntau yam qauv hauv tsev thiab thoob ntiaj teb, suav nrog:
- Txuj: ASTM A53, ASTM A500
- API 5L
- EN 10219, EN 10217
- GB / T 9711, GB / T 3091, thiab lwm yam.
Cov qauv sib txawv muaj cov kev cai meej ntawm cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev tshuaj xyuas cov kav dej steel. Thaum lub sij hawm kev yuav khoom, cov ntaub ntawv tsim lossis cov kev qhia tshwj xeeb yuav tsum tau siv los ua lub hauv paus kom tsis txhob muaj qhov txaus ntshai txaus ntshai vim yog cov qauv tsis sib haum.
Nyob rau hauv cov nqe lus ntawm kev xaiv qib steel, tag nrho xav txog kev tsim siab, kev khiav hauj lwm ib puag ncig, thiab kev nyab xeeb, thiab tsis txhob ua qhov muag tsis pom kev nrhiav cov qib siab steel kom nce nqi tsis tsim nyog.
3. Tsom ntsoov rau Raw Material Steel Strip Stability
ERW steel kavsiv kub- dov steel strips raws li cov khoom siv tseem ceeb, thiab lawv cov kev ruaj ntseg zoo muaj feem cuam tshuam rau cov kav hlau ua tiav. Cov ntsiab lus tseem ceeb rau kev tsom mus rau thaum lub sijhawm yuav khoom muaj xws li:
Seb lub steel sawb yog los ntawm ib tug ruaj khov steel zeb
Tsawg qhov hloov pauv hauv cov tshuaj muaj pes tsawg leeg
Seb lub yield zog thiab elongation ua tau raws li tus qauv yuav tsum tau
Muaj daim ntawv pov thawj raw khoom zoo
High- zoo ERW steel kav feem ntau yog siv tshwj xeeb pipeline steel los yog structural steel strips thiab coj nruj re- tshuaj xyuas thaum nkag los xyuas kom meej stability thaum vuam thiab sib sau.
4. Vuam txheej txheem thiab Weld zoo tswj
Cov txheej txheem tseem ceeb ntawmERW steel kavnyob rau hauv siab - zaus hluav taws xob kuj welding, thiab weld zoo ncaj qha txiav txim siab kev pabcuam kev nyab xeeb ntawm cov kav dej. Mature ERW vuam txheej txheem yuav tsum muaj cov yam ntxwv hauv qab no:
ruaj khov tswj ntawm vuam kub thiab siab
Tag nrho thiab nruam weld fusion
Uniform qauv hauv cheeb tsam weld
Tsis pom qhov tsis muaj fusion lossis overheating teeb meem
Thaum lub sijhawm yuav khoom, tsom ntsoov rau seb cov chaw tsim khoom puas siv cov cuab yeej siv siab tshaj - vuam zaus thiab tau ua tiav ntawm -kab vuam xyuas thiab cov txheej txheem tshuaj xyuas tom ntej.
5. WeldSeamKev tshuaj xyuas thiab kev soj ntsuam tag nrho cov yeeb nkab tsis tuaj yeem uaSaib tsis taus
Tsim nyog ERW steel kav tsis yog tsuas yog nyob rau hauv cov txheej txheem tswj tab sis kuj nyob rau hauv lub systematic kev soj ntsuam xyuas kom zoo. Cov khoom tshuaj ntsuam xyuas muaj xws li:
Weld ultrasonic kuaj
Eddy kev sim tam sim no
Kev ntsuam xyuas hydrostatic
Dimensional thiab tsos tshuaj xyuas
Rau cov haujlwm uas yuav tsum muaj kev nyab xeeb siab, nws raug nquahu kom ua ntej cov khoom lag luam nrog cov kev soj ntsuam zoo sib xws, ua tiav cov ntaub ntawv tshuaj xyuas, thiab kev taug qab, uas tseem yog lub hauv paus tseem ceeb rau kev txiav txim siab ntawm cov neeg tsim khoom kev tshaj lij.
6. Dimensional raug thiabQhov tshwm simZooKev soj ntsuam
Ib qho txiaj ntsig tseem ceeb ntawm ERW steel kav yog lawv qhov zoo sib xws, tab sis qhov no yog premised ntawm cov cuab yeej tsim nyog thiab cov txheej txheem tswj. Thaum muab khoom, tsom rau:
Kev ruaj ntseg ntawm sab nraud thiab phab ntsa thickness
Ovality tswj
Cov yeeb nkab ncaj
Cov yeeb nkab kawg bevel thiab kawg lub ntsej muag zoo
Kev tswj qhov ntev zoo tsis tsuas yog ua kom yooj yim ntawm - qhov chaw teeb tsa tab sis kuj txo cov nqi ua haujlwm thiab rov ua haujlwm dua.
7. Kev Tiv Thaiv -Cov Cai Tiv Thaiv Kev Tiv Thaiv thiab Kev Txhawb Nqa Tom Qab
Nyob rau hauv feem ntau cov haujlwm, ERW steel kav feem ntau xav tau los tiv thaiv- kev kho corrosion, xws li txheej, sab hauv / sab nraud los tiv thaiv- xeb, lossis txheej txheej tshwj xeeb. Thaum yuav khoom, xyuas seb cov chaw tsim khoom puas tuaj yeem muab:
Txhawb kev tiv thaiv- kev pabcuam corrosion
Kev tswj xyuas ib txwm muaj los tiv thaiv - cov txheej txheem corrosion thiab cov yeeb nkab steel zoo
Anti- kev tshuaj xyuas corrosion thiab kev lees paub
Cov neeg tsim khoom nrog kev tsim khoom sib xyaw ua ke thiab tiv thaiv- muaj peev xwm tiv thaiv corrosion feem ntau yog qhov muaj txiaj ntsig zoo rau kev tswj hwm qhov kev ua tiav tag nrho.
8. Kev Ntsuas Kev Ntsuas Tus Nqi thiab Ntev -Tsev Nqi
Nqe sib txawv ntawmERW steel kavHauv kev ua lag luam feem ntau yog los ntawm cov hauv qab no:
Qhov sib txawv ntawm qib raw khoom
Variations nyob rau hauv vuam thiab soj ntsuam kev nqis peev
Qhov sib txawv ntawm qhov nruj ntawm kev siv tus qauv
Qhov sib txawv ntawm cov kev tswj xyuas zoo
Hauv kev txiav txim siab ntawm kev yuav khoom, tsis txhob siv tus nqi qis raws li kev xaiv ib leeg; Hloov chaw, tsom mus rau qhov khoom ntev - lub sijhawm ruaj khov thiab qhov kev pheej hmoo tswj kev muaj peev xwm.
Xaus
Kev yuav ERW steel kav tsis yog tsuas yog hais txog kev sib piv cov lus qhia tshwj xeeb; nws yog qhov kev txiav txim siab dav dav- ua cov txheej txheem uas sib txuas cov kev xav tau ntawm engineering, txheej txheem tsim khoom, thiab kev tswj xyuas kom zoo. Tsuas yog los ntawm kev nkag siab tag nrho cov kev npaj siv, cov qauv siv tau, cov khoom siv raw, vuam seam zoo, thiab kev sim tshuab tuaj yeem xaiv ERW steel yeeb nkab khoom uas tsim nyog rau qhov project.
