3. Socket Weld Thermowells: Lub qhov (socket weld thermowells) muaj lub qhov (socket) ntawm ib kawg, uas tuaj yeem welded rau hauv cov txheej txheem yeeb nkab lossis lub nkoj. Hom thermowell no muab kev sib txuas kom nruj thiab tsis muaj paug.
4. Weld-in Thermowells: Cov thermowells no tau muab tso rau hauv cov txheej txheem nkoj lossis cov yeeb nkab thiab tom qab ntawd welded ncaj qha los muab kev txhim kho ruaj khov thiab ruaj ntseg. Weld-in thermowells feem ntau yog siv rau hauv cov ntawv thov siab.
5. Sanitary Thermowells: Sanitary Thermowells yog tsim tshwj xeeb rau kev tu cev, xws li zaub mov thiab tshuaj lag luam. Lawv ua kom lub ntsej muag du, tsis muaj crevices lossis hnab ris, kom huv si yooj yim thiab tiv thaiv kev sib kis.
6. Vanstone Thermowells: Vanstone thermowells muaj kev sib cais tsim thiab siv thaum qhov chaw teeb tsa raug txwv. Lawv tuaj yeem nkag tau yooj yim ntawm ob lub flanges yam tsis tas yuav tsum muaj cov fittings ntxiv.
Cov khoom siv rau Thermowells
Kev xaiv cov khoom siv rau cov thermowells nyob ntawm cov txheej txheem txheej txheem, nrog rau qhov kub thiab txias, siab, thiab qhov xwm txheej ntawm cov txheej txheem xov xwm. Qee cov khoom siv siv rau cov thermowells muaj xws li:
1. Stainless Hlau: Stainless hlau thermowells muab kev tiv thaiv zoo rau corrosion thiab kub kub. Lawv tau siv dav hauv ntau yam kev lag luam, suav nrog tshuaj lom neeg, petrochemical, thiab tsim hluav taws xob.
2. Brass: Brass thermowells yog tus nqi tsim nyog thiab tsim nyog rau kev siv qis qis. Txawm li cas los xij, lawv yuav tsis zoo tagnrho rau qhov chaw corrosive.
3. Carbon Steel: Carbon steel thermowells muab lub zog zoo heev thiab kev cuam tshuam tsis zoo. Lawv feem ntau yog siv rau hauv cov ntawv thov kev lag luam.
4. Inconel thiab Hastelloy: Cov alloys ua tau zoo no yog siv nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig uas stainless hlau yuav tsis txaus.
Kev siv ntawm Thermowells
Thermowells pom cov ntawv thov hauv ntau qhov kev lag luam uas ntsuas qhov ntsuas kub yog qhov tseem ceeb. Qee cov ntawv thov siv xws li:
1. Roj thiab Roj: Thermowells tau siv dav hauv kev lag luam roj thiab roj rau kev ntsuas kub hauv cov kav dej, cov chaw tsim khoom, cov chaw tawm sab nrauv, thiab cov tso tsheb hlau luam.
2. Tshuaj thiab Petrochemical: Hauv cov nroj tsuag tshuaj thiab petrochemical, cov thermowells yog siv los saib xyuas qhov kub thiab txias hauv reactors, kab distillation, thiab cov hlab ntsha.
3. Kev Tsim Hluav Taws Xob: Thermowells ua lub luag haujlwm tseem ceeb hauv cov nroj tsuag tsim hluav taws xob, uas lawv siv rau kev ntsuas kub hauv boilers, turbines, condensers, thiab heat exchangers.
4. Khoom noj khoom haus thiab dej haus: Cov thermowells huv huv yog siv hauv kev lag luam khoom noj thiab dej haus kom ntseeg tau tias muaj kev tswj xyuas qhov kub thiab txias thaum lub sij hawm tsim khoom thiab khaws cov khoom puas tsuaj.
