Rising qia rooj vag Valves

Peb lub qhov rooj qhib qhov rooj muaj qhov pom tseeb qhib / kaw, txhim khu kev sib khi, thiab lub cev muaj zog hlau hlau, zoo tagnrho rau kev tiv thaiv hluav taws thiab cov kav dej xa dej nrog lub sijhawm ntev -.

Ca-Kev Tiv Thaiv Hluav Taws Xob Co., Ltd yog ib qho ntawm cov tuam txhab muaj kev ntseeg siab tshaj plaws thiab cov chaw muag khoom ntawm qhov 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.

nce qia rooj vag li qub

Ntev npaum li cas qhov kev pab cuam lub neej ntawm nce qia rooj vag li qub nyob rau hauv nquag ua lag luam circulating dej systems piv rau cov dej zoo tib yam scenarios?

Nyob rau hauv cov xwm txheej zoo tib yam dej, nce qia rooj vag li qub feem ntau muaj kev pab cuam lub neej ntawm 10 mus rau 15 xyoo nrog kev tu kom zoo. Hauv kev ua haujlwm nquag ua haujlwm hauv dej, qhov kev ua neej no feem ntau luv rau 5 txog 8 xyoo, txo qis ntawm 40% mus rau 50%.

Cov laj thawj tseem ceeb yog ua kom cov khoom siv nrawm nrawm los ntawm kev qhib / kaw ntau zaus, uas ua rau qias sai sai - ntim cov chaw sib txhuam thiab lub ntsej muag sealing. Muaj cov dej ntws los kuj feem ntau nqa cov khib nyiab pov tseg, sediment, lossis cov kab corrosive, uas ua rau kom nrawm dua sealing tivthaiv yaig thiab raug qia corrosion. Kev vibration thiab siab hloov pauv hauv cov tshuab circulating ntxiv ua rau cov khoom qaug zog. Thaum kev saib xyuas tsis tu ncua (xws li qia lubrication, hloov foob, thiab tshem tawm cov khib nyiab) tuaj yeem txo qhov hnav, nws tsis tuaj yeem cuam tshuam qhov cuam tshuam ntawm kev ua haujlwm nquag thiab dej hnyav, ua rau lub neej ua haujlwm luv dua.

Dab tsi cov khoom siv kho kom zoo yog xav tau rau kev nce qia rooj vag li qub hauv kab kua qaub-alkali corrosive pipelines?

Hloov kho mus rau Corrosion-Resistant Alloy Stems

Rau cov kab mob acid-alkali ib puag ncig, hloov cov qauv carbon steel stems nrog siab- cov ntaub ntawv alloy yog qhov ua kom zoo tshaj plaws. Cov kev xaiv zoo li 316L stainless hlau los yog duplex stainless hlau muaj qhov ua haujlwm tsis zoo rau cov kua qaub thiab alkali corrosion, ua haujlwm zoo dua qub los ntawm kev tiv thaiv pitting thiab crevice corrosion. Cov alloys no tuav cov qauv kev ncaj ncees txawm tias ntev - lub sij hawm raug rau cov kab corrosive ions, txo txoj kev pheej hmoo ntawm qia embrittlement lossis tsis ua haujlwm. Thaum tus nqi pib cov khoom nce, nws txo qis txij nkawm thiab ncua lub neej ntev ntawm lub valve, ua rau tus nqi -kev xaiv zoo rau cov kav xa dej.

Surface Hardening thiab Anti-Coating Coating

Siv cov txheej tiv thaiv saum npoo rau stems tsim ib qho kev tiv thaiv kev tiv thaiv corrosive media. Cov txheej txheem zoo li thermal txau ntawm npib tsib xee-raws li alloys los yog electroless npib tsib xee plating ua ib txheej tuab, impermeable uas cais cov qia hauv paus cov ntaub ntawv los ntawm cov kab mob acids thiab alkalis. Cov txheej txheem no tiv thaiv tshuaj tua kab mob thaum tuav lub qia lub zog thiab hnav tsis kam thaum ua haujlwm. Kev tshuaj xyuas tsis tu ncua yuav tsum tau kuaj xyuas cov txheej txheej tawg lossis tev, vim tias qhov chaw puas tuaj yeem nthuav tawm cov hlau hauv qab mus rau corrosion. Qhov no optimization yog zoo tagnrho rau retrofitting li qub uas twb muaj lawm yam tsis muaj tag nrho qia hloov.

Composite Material Cladding rau Stem Protection

Cladding stems nrog corrosion-cov ntaub ntawv sib xyaw resistant muaj tus nqi- siv tau zoo rau kev hloov kho tag nrho cov hlau. Cov kev xaiv muaj xws li PTFE lossis PEEK polymer txheej, los yog cov txheej txheem ceramic siv rau lub qia nto. Cov ntaub ntawv no tshem tawm cov kua qaub-alkali daws, tiv thaiv kev sib cuag ncaj qha ntawm cov xov xwm corrosive thiab qia hlau. Lub cladding kuj txo cov kev sib txhuam ntawm qia thiab ntim, txo qis hnav thaum ua haujlwm nquag. Txawm li cas los xij, lub cladding thickness yuav tsum tau ua tib zoo tswj kom tsis txhob muaj kev cuam tshuam qia seem qhov tseeb, kom ntseeg tau tias kev ua haujlwm du valve thiab txhim khu kev qha sealing kev ua tau zoo.

Kev xaiv cov khoom raws li cov yam ntxwv nruab nrab

Kev ua kom zoo yuav tsum ua raws li cov kab mob tshwj xeeb -alkali concentrations thiab kev ua haujlwm kub. Rau cov organic acids tsis muaj zog, 304 stainless hlau yuav txaus, thaum muaj zog alkalis xav tau 316L lossis siab dua alloys. Ntawm qhov kub siab, cov ntaub ntawv zoo li Hastelloy lossis titanium muaj kev tiv thaiv corrosion zoo dua. Cov pab pawg engineering yuav tsum txheeb xyuas cov ntaub ntawv qhia txog dej kom paub cov ntsiab lus corrosive ions, tom qab ntawd xaiv cov khoom qias neeg uas phim qhov nruab nrab qhov kev ua phem. Txoj kev tsom mus rau no zam dhau - engineering (thiab cov nqi tsis tsim nyog) thaum ua kom lub qia tiv taus ntev - lub sij hawm raug rau cov kab corrosive yam tsis muaj degradation.
