Qhov cuam tshuam ntawm Kev Kho Mob ntawm Stainless Hlau Fittings thiab Flanges
Taw qhia:
Cov neeg tsim khoom ntawm stainless hlau fittings thiab flanges yuav tsum xav txog cov nqi tsim khoom thaum tseem hais txog yam cuam tshuam txog kev tiv thaiv corrosion thiab khoom zoo. Nws tau raug pom tias qee lub tuam txhab tsis siv cov kev kho mob thaum lub sij hawm tsim cov fittings, tsuas yog nyob rau polishing, txhaj tshuaj blasting, thiab lwm txoj hauv kev los zais qhov tsis xws luag thiab qhov tsis zoo. Txoj hauv kev no tuaj yeem ua rau muaj kev pheej hmoo mus ntev thiab teeb meem mus tas li hauv kev siv tau ntawm stainless hlau fittings thiab flanges. Hauv tsab xov xwm no, peb tshawb nrhiav qhov tseem ceeb ntawm kev daws teeb meem hauv cov txheej txheem tsim khoom, tsom mus rau nws qhov cuam tshuam rau stainless hlau fittings thiab flanges.
Cov yam ntxwv ntawm Kev Kho Mob rau Stainless Hlau:
Stainless hlau yog ib hom hlau tshwj xeeb uas muaj cov ntsiab lus alloying xws li nickel thiab chromium. Kev kho cua sov txheej txheem rau stainless hlau txawv ntawm cov qauv hlau.
1. Tsawg Thermal Conductivity: Stainless hlau muaj cov thermal conductivity qis dua piv rau carbon steel. Nyob rau hauv chav tsev kub, nws thermal conductivity tsuas yog 27% ntawm carbon steel. Lub thermal conductivity ntawm stainless hlau maj mam evens tawm nrog nce kub. Yog li ntawd, thaum cua sov stainless hlau ntawm qhov kub thiab txias, cov txheej txheem cua sov yuav tsum maj mam ua.
2. Carbide Txhaum Cai: Kev daws teeb meem ntawm austenitic stainless hlau suav nrog cua sov nws mus txog 1100 degree. Qhov kub no inhibits qhov tsim ntawm carbides, thiab ceev ceev txias rau chav tsev kub tom qab oversaturates carbon, ho txhim khu lub stainless hlau corrosion kuj.
3. Kev tiv thaiv los ntawm Gases: Thaum lub sij hawm kho cov txheej txheem, cov fittings yog tiv thaiv los ntawm gases xws li hydrogen (H2). Qhov kev tiv thaiv no tiv thaiv kev tsim cov nplaum hlau oxide rau ntawm cov hlau tsis huv, ib yam khoom uas tuaj yeem cuam tshuam cov khoom siv ncaj ncees.
Peb Lub Ntsiab Tseem Ceeb ntawm Kev Kho Mob Stainless Hlau:
Qhov zoo ntawm cov tshuaj kho nyob rau hauv cov txheej txheem tsim khoom muaj feem cuam tshuam rau corrosion kuj, nto tiav, thiab kev ua haujlwm ntawm stainless hlau fittings. Yog li ntawd, cov txheej txheem kev kho cua sov rau stainless hlau plays lub luag haujlwm tseem ceeb hauv kev tsim cov hlau stainless fittings.
1. Kev Kho Mob Kub Kub: Cov tshuaj kho qhov kub thiab txias rau stainless hlau yuav tsum tau khaws cia nyob rau hauv thaj tsam ntawm 950-1150 degree kom ua tiav cov nyhuv softening. Qhov no txo cov hardness ntawm stainless hlau kom qis dua 220 HV, ua tau raws li qhov yuav tsum tau ua kom zoo rau cov kav dej. Yog tias qhov ntsuas kub tsis tswj tau zoo, ntau yam tsis zoo yuav tshwm sim.
2. Lub Sijhawm Kho Mob: Cov txheej txheem cua sov hauv austenitic stainless hlau txo cov ntsiab lus ferrite seem hauv cov hlau thaum lub sijhawm cua sov nce. Kev kho mob rau stainless hlau fittings yuav tsum tau tswj nyob ib ncig ntawm 1050 degree kom saturate carbon thiab txhim khu corrosion kuj. Cov cua txias sai sai hauv cov huab cua puag ncig ces solidifies cov tshuaj kho nyhuv.
3. Kev kho tus nqi thiab tuav: Stainless hlau muaj cov thermal conductivity tsawg, uas ua rau qeeb cua sov dissipation. Yog li ntawd, thaum cua sov stainless hlau ntawm qhov kub thiab txias, cov txheej txheem cua sov yuav tsum maj mam. Cov cua kub ntau dhau tuaj yeem ua rau deformation, yog li nws yog ib qho tseem ceeb los tswj cov cua kub hauv ib qho chaw. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau lub sijhawm tuav. Piv txwv li, thaum cua sov 316L steel nyob ib ncig ntawm 1100 degree nrog ncua sij hawm tuav, cov seem ferrite cov ntsiab lus tsis tu ncua txo.
