1.Nqe lus nug: Dab tsi yog daim ntawv thov tseem ceeb rau LSAW Yeeb Nkab, EFW Yeeb Nkab, ERW Yeeb Nkab, thiab HFW Yeeb Nkab?
1.Cov lus teb: LSAW Yeeb Nkab: Feem ntau siv rau ntev - cov roj thiab cov kav dej, qhov loj - cov kav dej hauv nroog thiab cov kav dej, cov hauv paus ntug dej hiav txwv, thiab cov qauv choj; haum rau loj - txoj kab uas hla, tuab- phab ntsa, thiab siab - kev siv siab.
EFW Yeeb Nkab: Feem ntau siv rau kev thauj cov kua dej, cov khoom siv, cov roj tsheb, thiab cov cuab yeej siv kho mob; haum rau me me - mus rau - nruab nrab txoj kab uas hla, nyias-walled, thiab siab - daim ntawv thov precision.
ERW Yeeb Nkab: Feem ntau yog siv rau kev siv dej dav dav thiab kev tso dej, tsim kev txhawb nqa, qis - roj xa hluav taws xob, thiab kev ua liaj ua teb dej; haum rau nruab nrab - mus rau - tsis tshua muaj siab thiab dav siv.
HFW Yeeb Nkab: Feem ntau yog siv rau cov roj drilling thiab cov kav dej ntau lawm, siab -cov pa xa hluav taws xob, kev hloov pauv seamless yeeb nkab, thiab cov tshuab hluav taws xob hauv tsheb; haum rau nruab nrab-rau-siab siab, siab-precision, thiab siab- siv zog.
2.Nqe lus nug: Vim li cas LSAW Pipe nyiam tshaj ERW/HFW Yeeb Nkab rau ntev -cov roj thiab roj kav?
2.Cov lus teb: Muaj peb lub laj thawj tseem ceeb: Ua ntej, LSAW cov kav dej tuaj yeem tsim ** txoj kab uas hla loj (DN400 thiab siab dua) thiab tuab -walled (16mm thiab siab dua)** cov kav dej, ua tau raws li qhov yuav tsum tau ua ntawm cov kav dej ntev - deb. ERW/HFW kav yog ib qho nyuaj rau tsim rau ultra- loj diameters thiab phab ntsa thicknesses. Qhov thib ob, cov kauv vuam ntawm LSAW cov kav dej tuaj yeem faib cov kev ntxhov siab ntawm cov raj xa dej, muab kev tiv thaiv zoo rau axial nro thiab dabtsi yog khoov deformation, thiab hloov mus rau cov kev hloov hauv av thaum lub sij hawm tso dej. Thib peb, submerged arc vuam txheej txheem ntawm LSAW cov kav dej yog qhov paub tab, nrog rau qhov siab vuam qhov tsis pom kev hla tus nqi, thiab nws qhov kev ua tau zoo tuaj yeem ua kom zoo dua los ntawm kev kho cua sov tom qab kom tau raws li kev nyab xeeb thiab kev ntseeg siab ntawm cov kav dej ntev -. Hauv qhov sib piv, qhov ncaj seam weld ntawm ERW/HFW cov kav dej yog qhov ua rau muaj kev ntxhov siab nyob rau hauv loj - txoj kab uas hla, tuab - cov ntawv siv phab ntsa.
3.Cov lus nug: Vim li cas EFW cov kav dej nyiam rau cov roj tsheb thiab cov kav dej hauv tsev tub yees?
3.Cov lus teb: Cov ntsiab lus zoo ntawm EFW kav dej yog plaub npaug: Ua ntej, EFW kav dej muaj cov phab ntsa tuab (2.0-8.0mm) nrog lub thickness sib txawv ntawm tsawg dua los yog sib npaug rau ± 0.1mm, ua tau raws li qhov kev tswj xyuas qhov tseeb ntawm cov kav dej tsheb thiab cov kav dej tub yees. Second, EFW pipes have highly dense welds, free of pinholes and cracks, providing excellent sealing and preventing fluid leakage. Thib peb, EFW cov kav dej tuaj yeem tsim tau siv high-precision steel strips, nrog me me sab nraud txoj kab uas hla (tsawg dua los yog sib npaug rau ± 0.2mm), yoog rau qhov chaw sib cog lus hauv cov khoom siv. Plaub, kev tshawb nrhiav qhov tsis zoo hauv online tuaj yeem ua tiav thaum lub sijhawm EFW yeeb nkab tsim cov txheej txheem, tso cai rau kev taug qab ntawm cov vuam zoo rau txhua cov yeeb nkab thiab txo qhov kev pheej hmoo ntawm cov khoom siv tsis ua haujlwm.
4.Cov lus nug: Dab tsi yog qhov sib txawv ntawm daim ntawv thov scenarios ntawm ERW kav thiab HFW kav hauv kev tsim kho engineering?
4.Cov lus teb: ERW cov kav dej feem ntau yog siv rau hauv kev tsim kho vaj tse rau cov kav dej dav dav thiab cov kav dej, cov kav dej saffolding steel, cov kav dej txhawb nqa, thiab sab nrauv phab ntsa formwork txhawb nqa. Lawv tsim nyog rau qis- siab, tsis yog- qhov tseeb load- cov xwm txheej, nrog tus nqi qis thiab tus nqi siab - ua tau zoo. HFW cov kav dej feem ntau yog siv rau hauv kev tsim kho vaj tse rau cov hluav taws tua hluav taws hauv cov tsev siab - nce siab, nruab nrab cua txias condensate kav, elevator qhia rail kav, thiab kab hlau rhuav phab ntsa cov kav dej. Lawv haum rau nruab nrab-siab siab, siab-precision, thiab siab{11}}lub zog scenarios. Txawm hais tias tus nqi siab dua me ntsis, lawv tuaj yeem txhim kho kev nyab xeeb thiab kav ntev ntawm lub tsev ua haujlwm.
5.Nrhiav: Dab tsi yog qhov kev txwv ntawm LSAW kav, EFW kav, ERW kav, thiab HFW kav dej hauv marine engineering?
5.Cov lus teb: LSAW Yeeb Nkab: Cov tub ntxhais welded yeeb nkab rau marine engineering, siv nyob rau hauv offshore platform pawg hauv paus thiab subsea roj pipelines. Txawm li cas los xij, nws cov kev txwv muaj xws li hnyav hnyav, tus nqi thauj mus los siab, thiab xav tau kev hnyav ntxiv -lub luag haujlwm tiv thaiv- xeb txheej (xws li peb- txheej polyethylene coatings) nyob rau hauv qhov tob heev corrosive - hiav txwv ib puag ncig, ua rau kev tsim kho nyuaj. EFW Yeeb Nkab: Siv tsuas yog rau me me - nplai seawater desalination cov kav dej thiab cov kav dej pabcuam rau cov chaw nyob ze ntug dej hiav txwv hauv marine engineering. Nws cov kev txwv muaj xws li nyias phab ntsa tuab thiab tsis zoo siab tsis kam, ua rau nws tsis haum rau siab -siab tob- hiav txwv scenarios. ERW Yeeb Nkab: Siv rau cov kav dej ntiav dej ze ze thiab cov kav dej hiav txwv marine wharf. Nws cov kev txwv muaj xws li tsis muaj zog tiv thaiv dej hiav txwv corrosion thiab xav tau kev saib xyuas tsis tu ncua. HFW Yeeb Nkab: Siv rau cov kav dej kom zoo rau kev sib sib zog nqus - cov cuab yeej tshawb nrhiav dej hiav txwv thiab cov kav dej tiv thaiv kab mob rau cov ntug dej hiav txwv. Nws cov kev txwv suav nrog qhov loj tsis txaus - txoj kab uas hla ntau lawm thiab qhov xav tau rau kev tswj xyuas nruj ntawm txheej adhesion nyob rau hauv tob - hiav txwv ib puag ncig.
