Ca-Kev Tiv Thaiv Hluav Taws Xob Co., Ltd yog ib qho ntawm cov tuam ntxhab thiab cov muag khoom ntawm flanged rooj vag valve hauv Suav teb. Txais tos rau kev lag luam wholesale kev cai ua khoom siv hluav taws xob ntawm tus nqi sib tw los ntawm peb lub hoobkas. Tiv tauj peb rau cov khoom pheej yig dua.

flanged rooj vag valves

Puas muaj cov flanged rooj vag li qub txhawb kev cai flange loj hloov kho kom tau raws li cov qauv sib txawv hauv cheeb tsam flange (piv txwv li, ASME, DIN, GB)?

Yog lawm, peb muaj flanged rooj vag li qub txhawb nqa kev cai flange loj hloov kho kom haum nrog ntau lub regional pipeline flange qauv, suav nrog ASME, DIN, thiab GB. Peb tuaj yeem tsim cov flange qhov ntev, ntsia liaj qhov rooj qauv, sealing lub ntsej muag hom (xws li tsa lub ntsej muag lossis lub ntsej muag tiaj tus), thiab kev ntsuas siab kom haum raws li qhov yuav tsum tau ua ntawm txhua tus qauv-txawm nws yog ASME B16.5 rau North American cov haujlwm, DIN 2501 rau European systems, lossis GB / T 13402 rau Suav pipelines.

Peb pab neeg ua haujlwm engineering koom tes nrog cov neeg siv khoom los tshuaj xyuas cov duab kos duab thiab cov kev qhia tshwj xeeb, ua kom muaj kev sib haum xeeb nrog cov yeeb nkab uas twb muaj lawm. Qhov kev hloov kho no tshem tawm qhov kev xav tau ntawm tus nqi ntawm -qhov chaw adapters lossis kev hloov kho, txhim kho kev txhim kho thiab txo qhov kev pheej hmoo ntawm kev xau. Thaum cov kev cai hloov kho tau ua tau, peb qhia cov neeg siv khoom kom muab cov ncauj lus kom ntxaws cov txheej txheem thiab qhov yuav tsum tau ua ua ntej txhawm rau txhim kho kev tsim khoom.

Peb cov kab ntau lawm yooj yim haum rau ob qho me me -batch kev cai xaj thiab loj - qhov kev xav tau ntawm qhov project, xa cov kev ntseeg siab, tus qauv- ua raws li li qub raws li qhov xav tau thoob ntiaj teb.

flanged rooj vag valves ---Yuav ua li cas ntxiv kev tiv thaiv kev tiv thaiv corrosion thiab dej sealing ntawm flange pob qij txha thaum flanged gate li qub siv rau hauv daim ntawv faus ntev -lub sij hawm?

Txhim kho Flange Lub ntsej muag tiv thaiv-Txheej Txheem Txheej Txheem thiab Gasket Xaiv

Rau faus flanged rooj vag li qub, thawj qhov kev ntsuas tseem ceeb yog siv ntau- txheej tiv thaiv- txheej txheej rau flange ntsej muag. Tom qab kev ntxuav thiab tshem tawm xeb tag, zinc-nplua nuj primer ua raws li epoxy hmoov txheej tsim muaj kev tiv thaiv zoo tiv thaiv av noo thiab corrosive ions. Pairing qhov no nrog siab -kev ua tau zoo gaskets-xws li EPDM lossis graphite- hom kev txhawb zog- ua kom muaj kev sib khi dej nruj. Cov gaskets no tiv thaiv cov tshuaj corrosion thiab tuav elasticity nyob rau hauv ntev -lub sij hawm siab, tiv thaiv dej nkag mus uas accelerates flange xeb. Ua ntej- kev tshuaj xyuas kev teeb tsa tshem tawm cov txheej txheem tsis xws luag lossis gasket imperfections, nteg lub hauv paus ruaj khov rau kev sib koom ua ke.

Npog sab nraud sealing nrog tiv thaiv qhwv los yog lub tes tsho

Txhawm rau cais cov flange pob qij txha los ntawm faus av thiab noo noo, qhwv tag nrho flange sib dhos nrog corrosion- cov ntaub ntawv tiv taus yog qhov tseem ceeb. Cov kev xaiv muaj xws li butyl roj hmab los tiv thaiv- daim kab xev los yog cua sov- lub tes tsho shrinkable, uas ua kom nruj rau flanges, bolts, thiab valve lub cev. Ua ntej qhwv, txhua qhov chaw yuav tsum qhuav thiab khib nyiab-dawb kom ntseeg tau tias muaj adhesion. Thaum tshav kub kub- lub tes tsho shrinkable, thaum rhuab, tsim ib txheej seamless waterproof thaiv ntsev, noo noo, thiab av paug. Qhov kev tiv thaiv lub cev no tiv thaiv cov hlau ncaj qha- av tiv tauj, txuas ntxiv qhov sib koom ua ke ntawm corrosion{10}}dawb lifespan thiab tuav ntev -lub sij hawm watertightness.

Bolt thiab Fastener Corrosion Mitigation

Bolts thiab txiv ntseej yog cov ntsiab lus sib koom ua ke yooj yim tshaj plaws, xav tau kev tiv thaiv tsom. Siv cov kub-dip galvanized lossis stainless hlau fasteners muab qhov muaj zog tiv thaiv corrosion, tsis txhob xeb uas loosens pob qij txha thiab tawg cov ntsaws ruaj ruaj. Ua ntej kev teeb tsa, siv cov tshuaj tiv thaiv- xeb roj los yog molybdenum disulfide lubricant rau bolt threads txo kev sib txhuam thiab tsim cov dej noo- cov yeeb yaj kiab tiv taus. Tom qab zawm, npog txhua lub fastener nrog yas los yog roj hmab cap sealing av thiab dej, tiv thaiv corrosion uas yuav cuam tshuam kev sib koom ua ke. Cov kauj ruam no ua kom cov bolts nyob twj ywm ua haujlwm thiab nruj rau ntau xyoo ntawm kev pabcuam faus.

Backfill thiab Surrounding Environment Optimization

Kev hloov kho cov khoom siv rov qab tsim kom muaj qhov tsis zoo corrosive microenvironment ncig flange pob qij txha. Hloov cov av ib txwm nyob nrog huv, zoo- cov av nplaum av los yog bentonite yuav txo tau cov dej noo thiab thaiv cov ions corrosive. Rau siab - thaj chaw muaj kev pheej hmoo, embedding flanges nyob rau hauv ib tug pob zeb tiv thaiv txheej los yog waterproof casing ntxiv cais lawv los ntawm cov dej hauv av. Elevating flanges me ntsis saum toj ntawm lub trench hauv qab tiv thaiv cov dej tsub zuj zuj, thaum lub sij hawm cov txheej txheem dej directs noo noo. Tom qab- kev teeb tsa, kev tshuaj xyuas ib ntus los ntawm cov ntsiab lus nkag me me ua kom pom kev ntxov ntawm corrosion los yog xau, tso cai rau kev kho raws sijhawm ua ntej tsis ua haujlwm.
