Pipeline twj yog yog ua los ntawm cov ntaub ntawv hauv qab no:
- Nrum Hlau:Qhov no yog ib qho khoom siv. Cam khwb cia hlau muaj cov tshuaj tiv thaiv corrosion zoo heev thiab tshuab zog, yog qhov pheej yig, thiab haum rau kev tawm xov xwm xws li cov dej muaj kev lag luam. Txawm li cas los xij, nws yog hnyav, ua rau nws haum tsis haum rau cov ntawv thov uas qhov hnyav yog qhov kev txhawj xeeb.
- Tus Hlau Stainless:Cov twj tso kua mis stainless hlau muaj cov tshuaj tiv thaiv corrosion zoo heev thiab tiv taus kev tawm tsam los ntawm ntau yam tshuaj. Lawv tau dav siv nyob rau hauv cov tshuaj lom neeg thiab cov khoom lag luam los tshaj tawm ntau yam xov xwm corrosive. Cov ntaub ntawv uas muaj xws li 304 thiab 316 Lub 56 Stainless hlau muab ntau dua cov chaw uas muaj zog xws li chloride ions.
- Yas Khoom:Cov no suav nrog polypropylene (pp) thiab polyvinyl chloride (PVC). Cov twj tso kua mis yas ua hluav taws xob thiab kev xeb {1} {{{1} {tsis muaj kua thiab alkalis, thaum tseem ua tau qis- tus nqi. Txawm li cas los xij, cov plastics yog tsis muaj zog thiab tsis kub {{{tiv thaiv, ua rau lawv feem ntau haum rau kev xa tawm tsawg {{{{{
- Bronze:Bronze muaj kev hnav khaub ncaws zoo nkauj thiab feem ntau siv rau kev tshaj tawm xov xwm uas muaj cov khoom siv thiab dej phwj. Nws kuj tseem muaj lub zog kho tshuab thiab tuaj yeem tiv taus qee qhov kev ntsuas thiab hnav.
- Titanium:Titanium yog qhov siab - Kev ua haujlwm corrosion tsis kam, kev ua tau zoo heev txawm tias muaj cov acids tsis tshua muaj zog thiab cov hauv paus. However, it is expensive and is generally only used in applications where corrosion resistance is extremely demanding and cost-effective.
Cov ntaub ntawv sib txawv yog tsim nyog rau ib puag ncig ua haujlwm sib txawv thiab xov xwm. Thaum xaiv cov raj xa dej, nws yog ib qho tseem ceeb kom txiav txim siab cov khoom tsim nyog raws li cov kev thov ua kom ntseeg tau thiab muaj peev xwm.
