316 stainless hlau tshav kub exchanger
Dab tsi yog 316 cov cua kub exchanger raj?
Qib 316 cov raj yog qhov tseem ceeb ntawm cov kabmob qib.Nws tau ntxiv molybdenum uas muaj cov khoom zoo dua corrosion uas siab dua piv rau lwm hom qib.Nws pom zoo corrosion kuj nyob rau hauv ib puag ncig chloride.Nws tuaj yeem ua tau zoo heev welded thiab tsim tau yooj yim.Kev thauj mus los ntawm qib yog yooj yim raws li nws tau ntim zoo hauv cov ntoo crates thiab pallets.
Qib 316 muaj cov ntsiab lus xws li Cr, Ni, Si, Mn, thiab C. Nws kuj muaj cov khoom siv kho tshuab zoo dua vim muaj zog, elongation, yielding zog, thiab tensile zog.Cov credit rau lub cev muaj zog mus rau qhov zoo dua elastic modulus, ntom, thermal conductivity, hluav taws xob resistivity, thiab txhais tau tias thermal expansion.
Raws li qib posse lub siab corrosion kuj, nws tuaj yeem tiv taus kub hauv cov xov xwm tawv corrosive.Thaum raug crevice corrosion thiab pitting corrosion, nws muaj peev xwm tiv taus sov chloride ib puag ncig.Qhov kev ntxhov siab corrosion cracking muaj peev xwm nyob ib ncig ntawm 60 degree C tuaj yeem ua haujlwm los ntawm cov hlab.
Ntxiv rau qhov no, nws kuj muaj cov cua kub tsis kam, lub raj tuaj yeem ua haujlwm zoo hauv qhov kub thiab txias ntawm 870 ° C. Hauv kev pabcuam txuas ntxiv, lub raj tuaj yeem tiv taus qhov kub ntawm li 925 ° C. Lub zog ua rau nws yog cov khoom lag luam zoo tshaj plaws. uas tuaj yeem tiv taus ob qho tib si cov txheej txheem siab nrog rau qhov kub thiab txias.Nws tuaj yeem raug kho cua sov ntawm 1010-1120 ° C.
Lub vuam ntawm lub tshav kub exchanger raj yuav ua tau los ntawm muab tub lim hlau.Nws tau txhim kho machining thiab txo tus nqi ntawm cov cuab yeej hnav thaum ua haujlwm.
Test thiab cov ntaub ntawv
Qhov kev sim ua ntawm Stainless Steel 316 Heat Exchanger Tubes yog qhov kev sim flaring, micro / macro test, thib peb-tog soj ntsuam, thiab hardness test.
Cov ntaub ntawv muab yog daim ntawv xa nyiaj ua lag luam, daim ntawv lav, daim ntawv qhia tshwj xeeb, daim ntawv pov thawj fumigation, thiab daim ntawv ntim khoom.
