Kev tsim khoom
- Billet cua sov- Round steel billets yog rhuab nyob rau hauv ib tug teb rauv rau ib tug uniform dov kub.
- Piercing- Lub pob hluav taws kub yog pierced los ntawm nws qhov chaw siv lub pob zeb tho (Mannesmann txheej txheem) los tsim lub plhaub hollow.
- Elongating / Rolling- Lub plhaub hollow yog elongated thiab txo mus rau lub hom phiaj txheej kab thiab phab ntsa thickness siv ib tug sib dhos zeb, ntsaws zeb, los yog nruam mandrel zeb.
- Qhov loj me / txo- Lub tshuab sizing coj cov yeeb nkab mus rau qhov kawg qhov ntev ntev.
- Txias- Cov kav dej yog cua-tso rau ntawm lub txaj txias kom txo tau qhov kev ntxhov siab sab hauv maj mam.
- Kev kho cua sov (raws li xav tau)- Normalizing, quenching & tempering, los yog annealing yog siv nyob ntawm seb cov qib thiab cov cuab yeej cuab tam yuav tsum tau ua.
- Straightening, txiav & xaus tiav- Cov kav dej yog straightened, txiav kom ntev, thiab beveled los yog threaded rau ib qho kev txiav txim.
- Kev tshuaj xyuas & kuaj- Dimensional check, ultrasonic test (UT), hydrostatic testing, and mechanical property testing (tensile, yield, elongation, impact) ua ntej xa khoom.

Tag nrho daim ntawv pov thawj zeb xeem (MTC) ua raws li EN 10204 3.1 yog muab nrog rau txhua qhov khoom xa tuaj, thiab 3.2 ntawv pov thawj muaj nyob rau ntawm kev thov.
Vim li cas thiaj xaiv Kub Rolled Seamless Yeeb Nkab
- Tsis muaj weld seam- tshem tawm cov ntsiab lus tsis muaj zog rau ERW / welded yeeb nkab, txo qhov kev pheej hmoo ntawm seam tsis ua hauj lwm nyob rau hauv siab los yog cyclic loading.
- Siab siab thiab kub kam rau ua- zoo haum rau siab -siab gas kis, boiler, thiab siab -kub txheej txheem piping.
- Ntau hom phab ntsa thickness faibntawm cov ntsuas hnyav dua piv rau cov yeeb nkab txias seamless (CDS), ntawm tus nqi pheej yig dua rau cov kab loj dua.
- Kev tiv thaiv zoo dua rau kev khoov thiab torsional kev nyuaj siab, ua rau nws yog ib qho kev xaiv rau kev siv cov txheej txheem thiab tshuab.
Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog qhov txawv ntawm kub dov seamless yeeb nkab thiab txias kos seamless yeeb nkab?
A: Kub dov yeeb nkab yog tsim los ntawm qhov kub thiab txias thiab feem ntau yog siv rau cov kab loj loj thiab cov phab ntsa hnyav dua, nrog tus nqi pheej yig dua ib tuj. Cold drawn seamless (CDS) yeeb nkab yog ua tiav nyob rau hauv chav tsev kub tom qab kub dov, muab nruj dua dimension kam rau ua, ib tug smoother nto tiav, thiab zoo mechanical zog - tab sis feem ntau nyob rau hauv me me qhov ntau thiab tsawg thiab ntawm tus nqi siab dua. Xaiv kub dov thaum loj OD / hnyav phab ntsa thiab tus nqi efficiency tseem ceeb tshaj; xaiv txias kos thaum precision kam rau ua thiab nto tiav yog qhov tseem ceeb.
Q: Cov yeeb nkab kub dov seamless puas tuaj yeem siv rau siab - cov kav dej siab?
A: Yog. Qib xws li API 5L X42–X65 tshwj xeeb yog tsim los rau kev pabcuam roj thiab roj. Qib raug thiab phab ntsa tuab yuav tsum raug xaiv raws li qhov tsim kev ntsuas siab rau koj cov kav dej, tsis yog qhov loj ntawm cov yeeb nkab nominal.
Q: Qhov kev txiav txim yam tsawg kawg nkaus (MOQ) yog dab tsi?
A: MOQ txawv ntawm qhov loj thiab qib, txij li cov mills feem ntau khiav ntau lawm hauv batch. Qhov ntau thiab tsawg hauv Tshuag yuav muaj tsawg lossis tsis muaj MOQ, thaum tsis yog - qhov loj me lossis qib feem ntau xav tau qhov tsawg kawg nkaus tonnage los teem caij ua haujlwm. Hu rau peb nrog koj qhov kev xav tau tshwj xeeb rau qhov tseeb MOQ thiab lub sijhawm ua haujlwm.
Q: Kuv yuav ua li cas thiaj paub tias cov phab ntsa thickness (s teem sij hawm) kuv xav tau?
A: Phab ntsa thickness yuav tsum tau txiav txim los ntawm koj tus kws tsim qauv tsim raws li qhov yuav tsum tau muaj kev ntsuas siab, kev ua haujlwm kub, thiab cov qauv tsim qauv (xws li ASME B31.3, B31.8). Raws li tus neeg muag khoom, peb tuaj yeem paub meej tias lub sijhawm twg muaj nyob rau hauv Tshuag rau OD thiab qib, tab sis lub siab tsim kev suav nws tus kheej yuav tsum yog los ntawm koj qhov project engineering team lossis ib tus neeg thib peb tsim nyog.
