Carbon Steel vs. stainless hlau flanges: uas xaiv?
Thaum xaiv cov flanges rau koj cov pas dej piping, xaiv cov khoom muaj yog tseem ceeb los ua kom muaj kev cia siab, thiab lub zog. Ob ntawm cov ntaub ntawv nquag siv hauv flanges yogCov Hlau HlauthiabStainless hlauCov. Ntawm no yog qhov sib piv ntawm ob los pab koj txiav txim siab uas yog qhov zoo tshaj rau koj daim ntawv thov tshwj xeeb.
1. Cov khoom siv muaj pes tsawg
Cov Hlau Hlau: Tsim feem feem ntau ntawm cov hlau thiab carbon, carbon hlau yog cov khoom siv ntau yam. Nws kuj tseem tuaj yeem muaj cov nqi me me ntawm lwm cov khoom xws li manganese, silicon, thiab tooj.
Stainless hlau: Ua nrog tsawg kawg ntawm 10.5% chromium, stainless hlau yog cov tiv taus corrosion. Nws tseem muaj cov ntsiab lus xws li Nickel, Molybdenum, thiab qee zaum titanium, uas txhim kho nws lub zog, tsis kam, thiab txhua yam kav.
2. Lub zog thiab durability
Cov Hlau Hlau: Carbon Steel Flanges muaj lub zog siab tensile lub zog, ua rau lawv zoo tshaj rau cov kab ke uas ua haujlwm nyob rau hauv kev kub siab. Txawm li cas los xij, cov pa roj carbon hlau yog qub rau corrosion thaum raug rau noo noo thiab oxygen, uas tuaj yeem txo nws lossis pleev xim.
Stainless hlau: Stainless hlau flanges yog qhov zoo dua nyob rau hauv corrosion tsis kam, ua rau lawv zoo tagnrho rau kev siv nyob rau hauv cov chaw ib puag ncig uas raug rau cov chaw ib puag ncig, tshuaj lom neeg, lossis huab cua sov. Lawv tswj lawv lub zog thiab kev ncaj ncees txawm nyob hauv ib puag ncig hnyav.
3. Corrosion Kuj
Cov Hlau Hlau: Ib qho ntawm qhov loj tshaj plaws ntawm cov roj carbon steel yog nws qhov ntxim nyiam rau kev xeb, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog cov tshuaj siab siab los yog thaum raug tshuaj lom neeg zoo li cov kua qaub. Txhawm rau tawm tsam qhov no, cov hlau siv hluav taws xob yuav xav tau cov txheej txheej lossis kev saib xyuas tas li.
Stainless hlau: Stainless hlau paub zoo nyob rau hauv corrosion tsis kam vim cov chromium cov ntsiab lus, uas ua cov txheej oxide tiv thaiv uas tiv thaiv xeb. Nws yog qhov tsim nyog tshwj xeeb rau ib puag ncig hnyav xws li cov tubrog nkoj, tshuaj lom neeg, thiab ua zaub mov noj.
4. Kub tsis kam
Cov Hlau Hlau: Cov pa roj carbon steel yog feem ntau haum rau cov ntawv thov ntawm qis dua rau qhov kub thiab txias (mus txog 400 degree). Kev kub siab tuaj yeem ua rau cov hlau ua kom tsis muaj zog lossis poob nws cov qauv txheej txheem kev ntseeg.
Stainless hlau: Stainless hlau tuaj yeem tiv taus qhov kub thiab txias (nce txog 800 degree lossis ntau nyob ntawm qib). Nws yog qhov zoo rau cov ntawv thov kub siab xws li kev hloov pauv cua sov, boilers, thiab cov tshuab raug rau cov xwm txheej huab.
5. Nqi
Cov Hlau Hlau: Cov pa roj carbon steel flanges feem ntau yog tus nqi ntau dua li cov hlau stainless. Yog tias qhov peev txheej yog qhov kev txhawj xeeb thawj thiab cov ntawv thov tsis koom nrog cov chaw muaj kev ruaj ntseg, cov hlau tuaj yeem yog qhov kev xaiv zoo.
Stainless hlau: Stainless cov hlau flanges yuav kim kim dua vim yog cov nqi siab dua ntawm cov ntaub ntawv raw thiab cov txheej txheem ua haujlwm nyuaj. Txawm li cas los xij, lawv cov kev siv taus ntev thiab ntev los tiv taus corrosion tuaj yeem ua rau lawv muaj txiaj ntsig kev nqis peev rau cov ntawv thov siab lossis tseem ceeb.
6. Txij Nkawm thiab Ntev
Cov Hlau Hlau: Xav tau kev saib xyuas ntau dua thiab saib xyuas, tshwj xeeb tshaj plaws hauv kev xeb ib puag ncig. Tej zaum yuav tsum muaj cov tsho tiv no, lossis lwm hom kev tiv thaiv corrosion yuav xav tau los txuas nws lub neej kev pabcuam.
Stainless hlau: Stainless hlau flanges yog tsawg-saib xyuas vim tias lawv ib txwm tiv taus corrosion. Lawv txoj kev ua kom ntev ua rau lawv zoo tshaj rau cov ntawv thov ntev hauv kev xav tau ib puag ncig.
7. Kev thov
Cov Hlau Hlau: Zoo tagnrho rau cov ntawv thov kev lag luam dav dav zoo liDej Pipelines, Roj & Roj, Chav, thiab kev tsim kho. Nws yog siv thaum corrosion kuj tsis yog qhov tseem ceeb tshaj plaws.
Stainless hlau: Zoo tshaj plaws rau cov ntawv thov uas xav tsis kam rau corrosion thiab tshav kub, xws liMarine ib puag ncig, kev ua yeeb yam, khoom noj thiab dej haus ntau lawm, thiabKws muag khoom lag luam.
8. Qhov hnyav
Cov Hlau Hlau: Cov pa roj carbon hlau yog denser thiab hnyav dua piv rau cov hlau stainless, uas tuaj yeem yog qhov kev txiav txim siab hauv cov ntawv thov uas muaj kev txhawj xeeb.
Stainless hlau: Stainless cov hlau yog sib dua thiab muaj txiaj ntsig zoo dua qub-rau-qhov hnyav piv, uas tuaj yeem muaj txiaj ntsig zoo rau cov ntawv siv hnyav, tshwj xeeb hauv cov ntawv thov hnyav.
