Ob qhov hluav taws xob tiv thaiv welded (ERW) thiab seamless (SMLS) steel yeeb nkab raug siv rau ntau xyoo lawm; Nyob rau tib lub sijhawm, cov txheej txheem siv los tsim txhua tus tau nce qib. Yog li qhov twg zoo dua?
1. Manufacturing welded yeeb nkab
Welded yeeb nkab pib tawm raws li ib tug ntev, coiled ribbon ntawm steel hu ua ib tug skelp. Cov pob txha raug txiav mus rau qhov xav tau ntev, ua rau ib daim ntawv tiaj tus. Qhov dav ntawm daim ntawv luv luv yuav dhau los ua cov yeeb nkab sab nraud, ib qho txiaj ntsig uas tuaj yeem siv los suav nws qhov kawg sab nraud txoj kab uas hla.
Cov nplooj ntawv duab plaub yog pub los ntawm lub tshuab dov uas curls ntev ntev mus rau ib leeg, tsim ib lub tog raj kheej. Nyob rau hauv cov txheej txheem ERW, high-frequency hluav taws xob tam sim no dhau ntawm cov npoo, ua rau lawv yaj thiab fuse ua ke.
Ib qho zoo ntawm ERW yeeb nkab yog tias tsis muaj fusion hlau siv thiab vuam seam tsis tuaj yeem pom lossis hnov. Qhov ntawd tsis pom zoo rau ob chav submerged arc vuam (DSAW), uas tawm tom qab ib qho pom tseeb weld hlaws uas yuav tsum tau muab tshem tawm nyob ntawm daim ntawv thov.
Welded yeeb nkab tsim cov txheej txheem tau txhim kho ntau xyoo. Tej zaum qhov kev nce qib tseem ceeb tshaj plaws yog qhov hloov mus rau qhov hluav taws xob ntau zaus rau vuam. Ua ntej xyoo 1970s, cov khoom siv hluav taws xob tsawg tau siv. Weld seams uas tsim los ntawm tsawg zaus ERW yog feem ntau ua rau corrosion thiab seam tsis ua hauj lwm.
Feem ntau welded yeeb nkab hom xav tau kev kho cua sov tom qab tsim khoom.
2. Kev tsim cov yeeb nkab seamless
Seamless piping pib raws li cov khoom cylindrical hunk ntawm steel hu ua billet. Thaum tseem kub, billets yog pierced los ntawm qhov chaw nrog ib tug mandrel. Cov kauj ruam tom ntej yog dov thiab ncab lub hollow billet. Lub billet yog precisely dov thiab ncab kom txog thaum nws ua tau raws li qhov ntev, txoj kab uas hla thiab phab ntsa thickness raws li teev los ntawm cov neeg muas zaub txiav txim.
Qee hom yeeb nkab seamless harden li lawv tau tsim, yog li kev kho cua sov tom qab kev tsim khoom tsis tas yuav tsum tau ua. Lwm tus xav tau kev kho cua sov. Nrog rau qhov tshwj xeeb ntawm cov yeeb nkab seamless koj tab tom txiav txim siab los kawm seb nws yuav xav tau kev kho cua sov.
3. Keeb kwm kev xav thiab siv rooj plaub rau welded vs. seamless steel yeeb nkab
ERW thiab seamless steel piping muaj nyob ua lwm txoj hauv kev niaj hnub no vim muaj keeb kwm kev xav.
Feem ntau, welded yeeb nkab tau suav hais tias yog qhov tsis muaj zog vim nws suav nrog lub vuam seam. Seamless yeeb nkab tsis muaj qhov pom qhov tsis zoo no thiab tau pom tias muaj kev nyab xeeb dua. Txawm hais tias nws muaj tseeb tias cov yeeb nkab welded muaj xws li cov seam uas ua rau nws qhov kev xav tsis muaj zog, cov txheej txheem tsim khoom thiab cov txheej txheem kev ruaj ntseg zoo txhua tus tau txhim kho mus rau qhov uas cov yeeb nkab welded yuav ua tau raws li qhov xav tau thaum nws qhov siab tsis dhau. Txawm hais tias qhov zoo dua yog qhov tseeb, qhov kev thuam ntawm seamless piping yog tias cov txheej txheem dov thiab ncab ua rau cov phab ntsa tsis sib xws piv rau cov tuab tuab ntawm cov ntawv hlau uas tau tsim los rau vuam.
Cov qauv kev lag luam uas tswj hwm kev tsim khoom thiab kev qhia tshwj xeeb ntawm ERW thiab seamless steel yeeb nkab tseem cuam tshuam cov kev xav. Piv txwv li, seamless piping yog yuav tsum tau rau ntau lub siab-siab, high-temperature daim ntaub ntawv nyob rau hauv cov roj & roj, hluav taws xob tsim thiab tshuaj industries. Welded piping (uas feem ntau pheej yig dua los tsim thiab dav dav) tau teev tseg thoob plaws txhua qhov kev lag luam ntev npaum li qhov ntsuas kub, siab thiab lwm yam kev pabcuam tsis pub dhau qhov ntsuas tau sau tseg hauv cov qauv siv tau.
Hauv kev siv cov qauv, tsis muaj qhov sib txawv ntawm kev ua haujlwm ntawm ERW thiab seamless steel yeeb nkab. Txawm hais tias ob qho tib si tuaj yeem teev sib hloov pauv tau, nws yuav tsis muaj txiaj ntsig los qhia txog seamless thaum pheej yig dua welded yeeb nkab ua haujlwm zoo sib npaug.
