Product Overview
Ncaj seam welded steel yeeb nkab yog cov yeeb nkab steel tsim nrog ib leeg weld seam khiav tag nrho ntev ntawm cov yeeb nkab nyob rau hauv txoj kab ncaj nraim, tig mus rau cov yeeb nkab axis - as opposed to kauv (helical) welded yeeb nkab, qhov twg seam wraps nyob ib ncig ntawm lub yeeb nkab lub cev ntawm lub kaum sab xis. "Straight seam welded" yog ib hom kev tsim khoom ntau dua li ib qho khoom lag luam: nyob ntawm txoj kab uas hla thiab phab ntsa thickness, nws yog tsim los ntawm ib qho ntawm ob txoj kev sib txawv:
- ERW (Electric Resistance Welded) ncaj seam yeeb nkab- siv rau me me mus rau nruab nrab txoj kab uas hla (feem ntau mus txog ~ 660mm), qhov twg steel kauj yog dov - ua rau ib tug cylindrical zoo thiab cov seam yog koom nrog siab - zaus hluav taws xob kuj welding, tsis muaj ntxiv muab tub lim hlau.
- LSAW (Longitudinal Submerged Arc Welded) ncaj seam yeeb nkab- siv rau nruab nrab mus rau loj diameters, qhov twg steel phaj yog txias - tsim (JCOE txheej txheem) los yog khoov (UOE txheej txheem) rau hauv ib lub tog raj kheej thiab cov seam yog welded nrog submerged arc vuam, siv muab tub lim, feem ntau nrog ib tug sab hauv thiab sab nraud weld pass.
Ob txheej txheem tsim cov yeeb nkab ncaj nraim, thiab ob qho tib si raug tsim los ua lwm txoj hauv kev rau cov kav hlau txuas (SSAW), uas feem ntau pheej yig dua rau nruab nrab - mus rau - txoj kab uas hla loj tab sis muaj qhov ntev tag nrho cov vuam seam ntev ntawm ib cov yeeb nkab thiab ib qho helical seam geometry uas qee cov qauv thiab cov ntawv thov siab qhia tawm.

Ncaj Seam vs Kauv Seam Pipe
Ib qho kev tsis meej pem ntau zaus rau cov neeg yuav khoom yog xaiv ntawm cov seam ncaj thiab kauv seam yeeb nkab ntawm cov kab sib tshooj (kwv yees li 406mm-1420mm, qhov twg ob qho tib si feem ntau muaj). Qhov sib txawv tseem ceeb uas cuam tshuam rau kev xaiv:
- Seam ntev thiab kuaj lub nra: Ib txoj kab ncaj nraim muaj ib txoj hlua khi rau ib txoj hlua ntev; ib tug kauv yeeb nkab ntawm tib qhov ntev muaj ib tug ntev npaum li cas tag nrho seam (vim txoj kev helical), lub ntsiab lus ntau dua tag nrho weld ntev los soj ntsuam, txawm tias niaj hnub automated UT feem ntau offsets qhov no hauv kev xyaum.
- Cov khoom tawm los ntawm phaj / coil: Kauv cov yeeb nkab tuaj yeem tsim los ntawm txoj kab dav dav dav ntawm ib txoj kab uas muab, qee zaum txhim kho cov khoom tawm los; ncaj seam LSAW yeeb nkab feem ntau xav tau cov phaj dav sib txuam ze rau ntawm txoj kab uas hla tiav.
- Roundness thiab tawm - ntawm -ovality: Ncaj seam LSAW yeeb nkab, tshwj xeeb tshaj yog tom qab kev nthuav dav, feem ntau ua tiav qhov kev sib tw nruj dua, uas tseem ceeb rau nruj - haum daim ntawv thov xws li piling thiab flange kev sib txuas.
- Kev lag luam convention los ntawm daim ntawv thov: Ntev-ntaus cov roj thiab cov roj xa mus rau cov kav dej feem ntau qhia ncaj nraim seam LSAW yeeb nkab rau API 5L, thaum cov dej xa mus thiab cov txheej txheem piling feem ntau lees txais ncaj nraim los yog kauv seam nyob ntawm qhov project specification thiab cov khoom siv hauv cheeb tsam.
Vim li cas thiaj xaiv Ncaj Seam Welded Yeeb Nkab
- Simplified, linear soj ntsuam txoj kev: Ib qho ncaj ncaj weld seam yog yooj yim rau kev taug qab thiab tshuaj xyuas tag nrho nrog automated ultrasonic kuaj (UT) cov tshuab piv rau qhov tsis tu ncua rotating helical seam.
- Predictable mechanical zog raws seam: Vim hais tias cov seam tsis qhwv ib ncig ntawm cov yeeb nkab ncig, ncaj seam yeeb nkab feem ntau qhia tau zoo ib yam hoop -kev taw qhia txhua yam khoom, uas qee qhov kev xav tau thiab cov qauv txheej txheem nyiam.
- Kev txhawb dav dav: Ncaj seam yeeb nkab (ob leeg ERW thiab LSAW) yog hais ncaj qha nyob rau hauv feem ntau cov qauv thoob ntiaj teb loj - API 5L, ASTM, EN, thiab ASME - simplifying specification thiab hla- ciam teb kev yuav khoom.
- Zoo dua rau qhov tseem ceeb - cov kav xa dej: Rau kev pabcuam qaub, siab -siab, lossis cov kav dej tawm sab nraud, ncaj seam LSAW yeeb nkab nrog ob -sided SAW vuam thiab puv -ntev UT / RT yog qhov kev tsim kho ntau dua rau qhov siab tshaj plaws weld kev ntseeg tau.
FAQ
Q: Puas ncaj seam welded yeeb nkab muaj zog dua kauv welded yeeb nkab?
A: Tsis yog los ntawm - lub zog nyob ntawm cov qib steel thiab phab ntsa thickness ntau dua li seam geometry. Txawm li cas los xij, ncaj seam yeeb nkab feem ntau muaj ntau qhov kev kwv yees thiab zoo li hoop- kev taw qhia cov cuab yeej cuab tam, uas yog vim li cas nws thiaj li nyiam rau siab - siab thiab tseem ceeb - cov kav dej.
Q: Qhov txawv ntawm ERW thiab LSAW ncaj seam yeeb nkab yog dab tsi?
A: ERW yeeb nkab yog tsim los ntawm coil siv siab - zaus kuj welding yam tsis muaj muab tub lim hlau, haum rau me me diameters thiab ntau lawm. LSAW yeeb nkab yog tsim los ntawm cov phaj siv submerged arc vuam nrog cov xaim xaim, haum rau cov kab loj dua thiab cov phab ntsa hnyav dua, feem ntau nrog ob sab hauv thiab sab nraud weld hla.
Q: Puas tuaj yeem ncaj seam welded yeeb nkab siv rau siab -siab gas pipelines?
A: Yog - ncaj seam LSAW yeeb nkab tsim rau API 5L nrog ob -sided SAW vuam thiab tag nrho -ntev NDT yog tus qauv tsim rau siab - roj thiab roj xa mus kav.
Q: Yuav ua li cas yog lub weld seam ntawm ncaj seam yeeb nkab tshuaj xyuas?
A: Cov qauv kev coj ua yog 100% ultrasonic kuaj (UT) raws qhov ntev seam ntev, nrog rau kev kuaj hluav taws xob (RT) feem ntau teev tias yog ib qho ntxiv lossis qhov chaw- kuaj xyuas qhov tseem ceeb lossis siab - kev pabcuam siab.
