ASME SA182 F316L Tube Sheet rau Kub Exchanger
Tso lus
ASME SA182 F316L Tubesheet yog dab tsi?
ASME SA182 F316L tubesheet yog cov khoom tseem ceeb, feem ntau yog cov phaj tuab nrog cov qhov tho qhov tseeb, ua los ntawm qis -carbon (L) 316 stainless hlau, ua raws li tus qauv ASTM A182. Nws yog haum rau siab - kub / siab - ib puag ncig siab thiab feem ntau yog siv hauv cov khoom siv hluav taws xob los txhawb cov raj, cov kua dej sib cais, thiab muab kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv corrosive ib puag ncig xws li petrochemical lossis marine daim ntaub ntawv. ASME SA182 F316L tubesheets peb muab yog cov feem ntau siv cov khoom siv hluav taws xob sib hloov hauv cov refineries thiab cov nroj tsuag tshuaj loj.

Hom sib pauv
Xaiv hom kub exchanger.
U-Tube tsuas muaj ib daim ntawv xwb. Cov hlab yog khoov rau hauv daim ntawv ntawm "U". Cov pob khoom tuaj yeem raug tshem tawm rau kev saib xyuas, tab sis sab hauv ntawm lub raj yog qhov nyuaj dua los ntxuav vim yog khoov.
Tsau muaj ob lub tubesheets uas tau kho ntawm txhua qhov kawg ntawm kev sib hloov thiab txuas rau ib leeg los ntawm cov raj ncaj. Ob lub tubesheets nyob ruaj ruaj, yog li qhov sib txawv thermal expansion tuaj yeem txhim kho ntawm lub plhaub thiab cov hlab. Ib qho kev sib koom ua ke yog qee zaum yuav tsum tau nqus cov thermal loj hlob. Koj yuav tsum xaiv ib hom kev ruaj khov ntawm tubesheet exchanger los ua cov ntsiab lus txheeb xyuas ntawm cov pob qij txha expansion.
Floating muaj ib tug tubesheet uas yog tsau (stationary) thiab ib tug uas yog dawb txav. Raws li ib tug tubesheetntab,txhua qhov sib txawv thermal expansion ntawm lub plhaub thiab cov hlab yog absorbed. Cov khoom sib pauv no yog cov khoom siv ntau yam thiab tseem kim tshaj plaws. Cov raj kuj tuaj yeem ntxuav tau yooj yim piv rau U- tube exchangers.
Daim ntawv thov tseem ceeb ntawm ASTM A182 F316L Tubesheets
Kev lag luam tshuaj lom neeg thiab petrochemical: Ntau yam khoom siv hluav taws xob sib txawv, cov condensers, thiab cov reactors siv los daws cov xov xwm corrosive xws li acids, alkalis, thiab ntsev.
Marine engineering: Seawater desalination nroj tsuag, nkoj tshav kub exchangers, thiab offshore platform cua txias tshuab.
Pharmaceutical thiab zaub mov kev lag luam: Cov txheej txheem cov cuab yeej xav tau cov khoom siv siab heev purity thiab corrosion kuj.
Kev lag luam hluav taws xob Nuclear: Cov tshuab ua kom txias thiab cov khoom siv hluav taws xob hloov pauv rau cov khoom tsis yog -nuclear.
Pulp thiab ntawv kev lag luam: tuav corrosive tshuaj tov.
ASTM A182 F316L cov ntaub ntawv raj tau ruaj ntseg ntim rau hauv cov dej noo- pov thawj yas qhwv, nrog kev tiv thaiv ntxiv los ntawm cov ntoo crates lossis steel thav duab los tiv thaiv kev puas tsuaj thaum thauj khoom thiab xyuas kom muaj kev nyab xeeb.
