Kev nkag siab txog qhov sib txawv ntawm cov mag thiab cov hlau tsis yog hlau yog qhov tseem ceeb hauv kev lag luam roj thiab roj. Kev xaiv cov hlau zoo rau ntau daim ntawv thov yog qhov tseem ceeb kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv thiab cov qauv. Ntawm ntau hom hlau siv, cov hlau tsis sib nqus (tsis yog-mag) thiab hlau nplaum (mag) hlau ua lub luag haujlwm tseem ceeb. Qhov kev tshaj tawm blog no yog lub hom phiaj los ua kom pom qhov sib txawv ntawm cov hlau tsis yog mag thiab mag, lawv cov yam ntxwv, kev siv, nrog rau qhov zoo thiab qhov tsis zoo ntawm kev siv txhua yam hauv cov roj thiab roj.
Dab tsi yog Cov Hlau Tsis-Magnetic?
Cov khoom uas tsis muaj cov khoom sib nqus thiab tsis nyiam cov hlau nplaum yog hu ua "cov hlau tsis muaj hlau nplaum". Cov hlau no muaj nuj nqis heev rau lawv cov kev tiv thaiv corrosion zoo heev thiab hluav taws xob conductivity, ua rau lawv haum rau ntau yam roj thiab roj siv. Cov hlau tsis muaj hlau muaj xws li:
Carbon Steel: Siv dav siv cov hlau tsis-mag hauv kev lag luam roj thiab roj vim nws pheej yig, lub zog, thiab ntau yam. Nws yog siv nyob rau hauv pipelines, cia tso tsheb hlau luam, structural Cheebtsam, thiab lub qhov dej. Thaum cov hlau tsis muaj zog rau corrosion, qhov no tuaj yeem txo los ntawm kev tiv thaiv txheej los yog inhibitors, piv txwv li.
Stainless hlau: Renowned rau nws superior corrosion kuj, durability, thiab aesthetic thov. Offshore platforms feem ntau siv stainless hlau los cuam tshuam nrog hnyav ib puag ncig, piping systems, thiab li qub. Stainless hlau alloys, xws li 316 thiab 304, yog qhov zoo dua rau lawv cov kev tiv thaiv corrosion thiab kub-kub siv.
Duplex Stainless Hlau: Muab cov yam ntxwv xav tau ntawm ob qho tib si austenitic thiab ferritic stainless hlau. Nws nthuav tawm lub zog zoo heev, tiv thaiv corrosion thiab kev ntxhov siab corrosion tawg, ua rau nws tsim nyog rau cov kav dej hauv qab dej, cov khoom siv hluav taws xob, thiab cov khoom siv siab.
Dab tsi yog Magnetic Metals?
unsurprisingly, sib nqus hlau feature magnetic zog thiab yog li ntawd attracted rau hlau nplaum. Hauv qee qhov kev siv roj thiab roj, cov khoom sib nqus no yog qhov zoo. Feem ntau siv mag hlau yog raws li nram no:
Carbon Steel (Magnetic): Cov hlau tsis tu ncua, tsis zoo li cov hlau tsis muaj steel, muaj cov khoom sib nqus. Sib nqus carbon steel pom cov ntawv thov hauv cov khoom siv drilling, cov cuab yeej downhole, thiab cov ntsuas dej sib nqus. Nws yog tus nqi-zoo thiab yooj yim muaj, ua rau nws nyiam xaiv rau qee yam cuab yeej.
Nickel-Based Alloys: Nickel-based alloys, suav nrog Inconel thiab Monel, yog mag hlau renowned rau lawv tshwj xeeb tsis kam mus rau huab cua kub, corrosion, thiab mechanical stress. Cov hlau no yog siv rau hauv cov li qub, cov khoom siv hluav taws xob sib hloov, thiab cov khoom raug cuam tshuam rau qhov chaw corrosive.
Pros thiab Cons ntawm Mag thiab Non-Mag Hlau
Kev xaiv ntawm hom hlau yog nyob ntawm cov kev cai tshwj xeeb thiab kev txiav txim siab. Koj yuav tsum xav txog ntau qhov zoo thiab qhov tsis zoo rau txhua qhov kev siv.
Tsis-Mag Metals:
Pros:
Zoo heev corrosion kuj, zoo tagnrho rau hnyav ib puag ncig.
Siab zog thiab durability.
Zoo hluav taws xob conductivity.
Muaj nyob rau hauv ntau qib thiab cov ntawv.
Cons:
Thaum muab piv rau lawv cov sib nqus sib nqus, cov hlau tsis-mag yuav kim dua
Tej yam uas tsis yog-mag hlau yuav tsum tau ntxiv cov txheej tiv thaiv los yog inhibitors los tiv thaiv corrosion.
Mag Hlau:
Pros:
Cov khoom sib nqus muaj txiaj ntsig zoo rau qee yam kev siv xws li magnetic flowmeter.
Nqi-zoo thiab yooj yim muaj.
Tsim nyog rau cov ntawv thov uas cov khoom sib nqus xav tau.
Cons:
Cov hlau nplaum hlau nplaum tuaj yeem ua rau muaj kev tiv thaiv corrosion tsawg dua piv rau cov hlau tsis muaj hlau.
Kev txwv tsis pub muaj qee yam alloys lossis qib.
Hauv kev xaus, cov hlau tsis sib nqus, xws li carbon steel, stainless hlau, thiab duplex stainless hlau, muaj kev tiv thaiv corrosion zoo heev thiab kav ntev. Ntawm qhov tod tes, cov hlau nplaum sib nqus, nrog rau qee yam carbon steels thiab nickel-based. Kev nkag siab txog qhov sib txawv ntawm cov hlau yog qhov tseem ceeb rau kev xaiv cov khoom tsim nyog hauv kev lag luam roj thiab roj.
