Cov Txheej Txheem Ntau Lawm Cov Lus Qhia ntawmLSAW steel yeeb nkab
Longitudinal Submerged Arc Welded (LSAW) steel yeeb nkab yog ib qho ntawm cov khoom tseem ceeb tshaj plaws siv nyob rau hauv loj - cov kav xa dej loj, kev thauj mus los ntawm lub zog, kev tsim hluav taws xob sab nrauv, thiab kev lag luam hnyav. Ua tsaug rau nws cov khoom siv kho tshuab zoo heev, qhov tseeb qhov tseeb, thiab siab dua - cov kabmob muaj peev xwm, LSAW steel yeeb nkab tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov haujlwm uas xav tau cov kab loj loj, cov phab ntsa tuab, thiab lub neej ua haujlwm ntev.
Tsis zoo li ERW steel yeeb nkab, uas yog tsim los ntawm kub- dov steel coils, LSAW steel yeeb nkab yog tsim los ntawm siab - zoo steel phaj. Cov txheej txheem tsim khoom pib nrog kev tshuaj xyuas phaj txhawm rau txheeb xyuas cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov tseeb qhov tseeb. Tom qab ntug milling, cov hlau phaj yog maj mam tsim rau hauv cov duab cylindrical siv cov thev naus laus zis xws li JCOE lossis Roll Bending Expansion .
Sab hauv thiab sab nraud longitudinal seams yog tom qab ntawd ua tiav nrog kev siv tsis siv neeg submerged arc vuam. Thaum lub sij hawm welding, hluav taws xob arc tseem npog tag nrho los ntawm granular flux, tiv thaiv cov hlau molten los ntawm atmospheric contamination thaum ua qhov sib sib zog nqus weld nkag thiab zoo heev metallurgical zog.
Tom qab vuam, ntau lub tuam txhab ua cov tshuab txuas ntxiv txhawm rau txhim kho kev sib tw thiab txo qis kev ntxhov siab. Txhua cov yeeb nkab ua tiav tom qab ntawd ua tiav kev soj ntsuam zoo, suav nrog kev kuaj ultrasonic, kuaj hluav taws xob, ntsuas hydrostatic siab, ntsuas qhov ntev, thiab kuaj pom ua ntej xa khoom.
Cov txheej txheem kev tsim khoom zoo no ua rau LSAW steel yeeb nkab kom txaus siab rau cov qauv thoob ntiaj teb xws li API 5L, GB / T 9711, ASTM A671, ASTM A672, thiab EN specifications.

Kev sib xyaw ua ke ntawm kev tsim khoom thiab kev tswj xyuas nruj ua rau LSAW steel yeeb nkab yog ib qho ntawm cov khoom siv txhim khu kev qha rau cov haujlwm loj engineering.
Yuav ua li cas xaiv txoj cai LSAW Steel Yeeb Nkab rau ib qhov project tshwj xeeb?
Xaiv qhov tsim nyog LSAW steel yeeb nkab yuav tsum muaj ntau tshaj li qhov tsuas yog xaiv qhov tseeb txoj kab uas hla. Cov kws ua haujlwm yuav tsum ntsuas ntau yam kev ua haujlwm, suav nrog kev ua haujlwm siab, thauj nruab nrab, ib puag ncig, kev pabcuam lub neej, kev teeb tsa, thiab cov qauv siv thoob ntiaj teb.
Xaiv qhov tsim nyog Steel Qib
Cov haujlwm sib txawv xav tau cov khoom sib txawv. Cov roj thiab cov kav xa hluav taws xob feem ntau qhia API 5L qib xws li X52, X60, X65, lossis X70 nyob ntawm kev tsim siab thiab kev ua haujlwm. Tej yaam num tej yaam num yuav txais GB / T 9711 qib xws li L245 los yog L360M, thaum muaj tej chaw yuav tsum tau ASTM specifications raws li qhov project qauv.
Siab dua - qib steel muaj zog feem ntau tso cai rau cov phab ntsa nyias nyias thaum tuav lub siab ua haujlwm, pab txo qhov hnyav tag nrho thiab cov nqi thauj mus los.
Xaiv qhov loj me thiab kev tiv thaiv nto
Pipeline txoj kab uas hla thiab phab ntsa thickness ncaj qha cuam tshuam kev thauj mus los muaj peev xwm thiab kev ua haujlwm ntawm cov qauv. Loj - txoj kab uas hla xa mus rau cov kav dej feem ntau xav tau cov phab ntsa tuab dua los tiv thaiv kev ua haujlwm siab dua thiab kev thauj khoom sab nraud.
Sib txuam txheej txheej txheej nrog kev pabcuam ib puag ncig
Kev tiv thaiv corrosion yog qhov tseem ceeb sib npaug. Cov kav dej hauv av feem ntau siv Fusion Bonded Epoxy (FBE) lossis Peb - Txheej Polyethylene (3PE) txheej txheej, thaum cov khoom siv sab nrauv feem ntau hais txog Peb- Txheej Polypropylene (3PP) cov tshuab rau kev txhim kho kev tiv thaiv rau qhov kub thiab txias thiab ib puag ncig marine. Sab hauv epoxy coatings kuj tseem raug xaiv rau kev xa dej lossis kev pabcuam tshuaj lom neeg kom txo tau qhov corrosion thiab txhim kho kev khiav haujlwm.
Xaiv qhov sib xyaw ua ke ntawm cov khoom siv qib, qhov ntev, thiab txheej txheej ua kom zoo dua qub thiab txhim kho txoj kev cia siab ntawm cov kav dej thiab txuas ntxiv lub neej kev pab cuam.
Vim li cas cov khoom Specifications tseem ceeb rau loj Engineering Projects?
Cov phiaj xwm loj loj yuav tsum tau ua raws li cov kev qhia tshwj xeeb los xyuas kom muaj kev sib haum xeeb ntawm cov kav dej thiab cov txheej txheem tsim kho.
Cov ntsiab lus tseem ceeb muaj xws li sab nraud txoj kab uas hla, phab ntsa tuab, qib steel, kev tsim qauv, kev tshuaj xyuas vuam, qhov ntev ntev, thiab txheej txheej txheej. Txawm tias me me sib txawv tuaj yeem cuam tshuam rau kev vuam, kev txhim kho kev ua haujlwm, lossis kev ua haujlwm ntev ntev -.
Cov neeg tsim khoom nrog cov chaw tsim khoom muaj peev xwm tswj xyuas cov txheej txheem nruj dua thoob plaws hauv kev npaj phaj, sib sau, vuam, nthuav dav, tshuaj xyuas, txheej, thiab ntim khoom. Qhov kev sib xws no txo qhov kev pheej hmoo ntawm txoj haujlwm thaum ua kom cov khoom ruaj khov zoo thoob plaws cov khoom loj.
Rau cov haujlwm thoob ntiaj teb uas muaj ntau txhiab tons ntawm cov yeeb nkab steel, cov kev qhia tshwj xeeb ua kom yooj yim rau kev thauj mus los, kev teeb tsa, thiab kev tswj xyuas zoo thaum txo kev tsim kho qeeb.
Lub peev xwm ua tau li cas cuam tshuam rau txoj haujlwm ua tiav?
Kev xaiv tus neeg muag khoom raug yog ib qho tseem ceeb raws li kev xaiv cov khoom raug cai. Cov kav dej loj loj feem ntau xav tau ntau txhiab tons ntawm cov yeeb nkab steel xa hauv cov sijhawm tsim kho nruj. Cov neeg tsim khoom yuav tsum yog li ntawd muab cov peev txheej ruaj khov ua ke nrog kev lees paub zoo.
Tus neeg tsim khoom tsim nyog yuav tsum muaj cov cuab yeej tsim kho siab heev, tsis siv neeg submerged arc vuam tshuab, tsis yog -cov chaw kuaj kev puas tsuaj, muaj peev xwm ntsuas hydrostatic, thiab ua tiav cov kev tswj xyuas zoo. Cov ntawv pov thawj thoob ntiaj teb thiab cov kev paub dhau los ua pov thawj ntxiv kev tsim kev ntseeg siab.
Ntxiv rau qhov muaj peev xwm tsim khoom, kev txhawb nqa kev pabcuam, kev pabcuam txheej txheej, kev ntim khoom xa tawm, kev sib koom ua haujlwm logistics, thiab teb tom qab- kev pabcuam muag tag nrho ua rau ua tiav qhov haujlwm tiav.
Ntev - kev koom tes nrog cov tuam txhab muaj kev paub dhau los pab cov neeg ua haujlwm engineering txo cov kev pheej hmoo ntawm kev yuav khoom thaum txhim kho kev tsim kho.
Qhov project siv:Zambia Deep Mine Dewatering Project
Ib daim ntawv thov sawv cev ntawm LSAW steel yeeb nkab yog qhovtob mine dewatering project hauv Zambia, qhov twg Huayang Steel Pipe muab kwv yees li1,061 tons ntawm LSAW steel yeeb nkabtsim nyob rau hauvX70Mqib nrog specifications suav nrog406 × 12 mm thiab 406 × 15 mmrau ib tug ntsug mine kua system mus txog qhov tob ntawm800-1,000 m.
Qhov project xav tau cov kav dej steel muaj peev xwm tiv taus siab sab hauv, xav tau kev ua haujlwm, thiab kev pabcuam txuas ntxiv hauv qhov nyuaj mining ib puag ncig. Los ntawm kev siv thev naus laus zis JCOE, ob chav submerged arc vuam, nruj tsis- kuaj kev puas tsuaj, thiab kev tshuaj xyuas zoo, cov kav dej xa khoom tau ua tiav raws li qhov project cov kev xav tau thiab muab kev txhawb nqa txhim khu kev qha rau mine's dewatering system.
Qhov kev ua tiav no qhia tau hais tias qhov tseem ceeb ntawm kev xaiv cov qib steel tsim nyog, phab ntsa thicknesses, thiab kev tsim khoom zoo thaum tsim cov khoom siv siab -kev ua haujlwm ntawm cov kav dej.
