Raws li tus kws tshaj lij ntawm cov yeeb nkab steel yeeb nkab fittings, Chengdu Shushengtai Steel Co., Ltd. hais txog qhov tseem ceeb ntawm kev daws teeb meem zoo thiab kev tiv thaiv kev saib xyuas kom ntev - lub sij hawm kev ntseeg siab thiab kev ua haujlwm zoo. Cov teeb meem tshwm sim xws li corrosion, sib koom ua ke, thiab ntws tawm - cuam tshuam txog kev ua haujlwm tsis zoo tuaj yeem cuam tshuam rau kev nyab xeeb thiab kev tsim khoom yog tias tsis kho kom raug. Cov hauv qab no qhia txog cov teeb meem tseem ceeb, cov hauv paus hauv paus, thiab cov kev ntsuas kho kom raug.
1. Corrosion-Cov teeb meem cuam tshuam
Deg corrosion yog ib qho kev sib tw ntau tshaj plaws hauv cov kav dej stainless hlau. Nws feem ntau yog tshwm sim los ntawm chloride infiltration, kev kho saum npoo tsis raug, lossis kev kis kab mob thaum lub sijhawm teeb tsa. Nyob rau tib lub sijhawm, cov xwm txheej no tuaj yeem ua rau pitting, crevice corrosion, lossis hauv zos rusting, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj av noo los yog ntsev.
Txhawm rau tiv thaiv corrosion, nws yog ib qho tseem ceeb rau:
· Xaiv cov qib stainless hlau tsim nyog (xws li, 316L rau chloride-ib puag ncig nplua nuj).
· Ua kom zoo passivation thiab nto tiav los kho cov txheej txheem chromium oxide tiv thaiv.
· Zam kom tsis txhob muaj kab mob los ntawm cov cuab yeej hlau los yog cov khoom thaum lub sij hawm tsim thiab teeb tsa.
· Kev tshuaj xyuas tsis tu ncua thiab tshuaj ntxuav tu pab tswj kev tiv thaiv corrosion thiab ua rau lub neej ntev.
2. Stress Corrosion Cracking (SCC)
Nyob rau hauv siab -kev nyuaj siab los yog corrosive ib puag ncig, kev nyuaj siab corrosion tawg tuaj yeem tshwm sim, tshwj xeeb tshaj yog nyob rau hauv fittings raug tensile stress thiab chlorides. Qhov teeb meem no muaj ntau dua nyob rau hauv siab - kub lossis cyclic siab siv. Thaum pib, SCC tuaj yeem nthuav tawm sai sai, cuam tshuam cov neeg kho tshuab kev ncaj ncees ntawm qhov haum.
Txhawm rau tiv thaiv SCC, engineers yuav tsum:
· Txo cov neeg kho tshuab kev ntxhov siab los ntawm kev tsim kev txhawb nqa thiab kev nthuav dav ntxiv.
· Ua kom muaj kev ntxhov siab-kev kho mob los yog hloov cov khoom siv rau cov hlau uas tiv taus ntau dua.
· Khaws cov kev ua haujlwm ruaj khov thiab tsis txhob muaj qhov kub thiab txias tam sim ntawd.
3. Kev sib koom ua ke thiab foob tsis ua haujlwm
Kev sib koom ua ke feem ntau yog tshwm sim los ntawm cov txheej txheem kev teeb tsa tsis raug, kev sib txuas tsis tiav, lossis cov khoom siv gasket puas hauv flanged kev sib txuas. Leaks tsis tsuas yog txo cov kev ua haujlwm ntawm lub cev tab sis kuj tuaj yeem ua rau muaj kev nyab xeeb tseem ceeb thiab kev pheej hmoo ib puag ncig.
Kev kho thiab kev tiv thaiv muaj xws li:
· Ua kom muaj kev sib raug zoo ntawm fittings ua ntej vuam los yog zawm.
· Siv cov txheej txheem vuam tsim nyog (WPS) thiab tswj cov cua sov kom tsim nyog kom ua tiav kev nkag mus rau tag nrho.
· Xaiv cov khoom siv gasket uas haum rau kev ua haujlwm kub, siab, thiab tshuaj lom neeg raug.
· Kev ntsuas siab niaj hnub tom qab kev teeb tsa yog qhov tseem ceeb rau kev txheeb xyuas kev sib koom ua ke ua ntej kev ua haujlwm.
4. Flow-Cov teeb meem kev ua tau zoo
Kev ua haujlwm tsis zoo xws li kev kub ntxhov, kev poob siab, lossis kev txwv tsis pub khiav tuaj yeem tshwm sim los ntawm kev xaiv tsis raug, kev tsis zoo sab hauv, lossis kev tsim qauv tsis zoo. Cov xwm txheej no tuaj yeem ua rau muaj zog hnav, kev co, thiab txo kev ua haujlwm.
Txhawm rau daws cov teeb meem ntws, nws raug nquahu kom:
· Siv precision-engineered fittings nrog du sab hauv nto kom txo tau kev sib txhuam.
· Optimize yeeb nkab routing thiab haum geometry kom tswj cov dej tsis tu ncua.
· Ua qhov ntsuas dej ntws thiab ntsuas kev ntsuas siab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhaws, nws, nws raug nquahu kom siv nws yuav tsum ua tib zoo saib xyuas cov khoom siv ntawm cov khoom siv hydraulic.
