Nta thiab Qhov Zoo
Vim tias nws cov khoom siv zoo tshaj thiab cov khoom siv muag muag, cov mos mos flanges muab cov khoom ntim zoo dua rau kev tiv thaiv nruab nrab to. Mos ua ke flanges tuaj yeem nqus tau kev hloov chaw thiab kev co hauv cov yeeb nkab tshuab, thiab yog li txo kev ntxhov siab thiab kev puas tsuaj rau cov yeeb nkab system. Qhov hloov tau yooj yim flange yog siv rau txhua hom nruab nrab thiab kub, thiab tuaj yeem txaus siab qhov yuav tsum muaj ntawm kev lag luam sib txawv. Piv nrog welded flange, lub installation ntawm cov mos sib koom ua ke yog qhov yooj yim thiab tsis xav tau vuam.
Daim Ntawv Thov Kev Thov
Ntiv nplhaib hom sib koom ua ke flanges tau siv dav hauv roj av hauv roj av, tshuaj, nkoj, metallurgical thiab lwm yam kev lag luam. Tshwj xeeb tshaj yog nyob rau hauv lub chaw ua haujlwm uas yuav tsum tau ua kom loj dua rau kev hloov chaw loj, kev co thiab kub hloov pauv tau zoo, muag muag cov flangible thiab ntsuas kev ua haujlwm mos siab muag.
Dab tsi yog lub nplhaib-hom sib koom tes (RTJ)
Ring-type joint (RTJ) flanges are a variation of the raised face flange design. RTJ flanges are typically used for more severe applications, particularly for high pressure systems, and/or high temperature systems (>750⁰C / 1,382⁰f). Nws muaj peev xwm siv RTJ flanges hla txhua chav kawm siab, tab sis lawv feem ntau siv rau chav kawm 900 thiab siab dua.
Qhov sib txawv ntawm ib qho RTJ flange thiab lub ntsej muag lub ntsej muag nrov flange yog txoj kev uas foob tau. Hlau Gaskets (Hard) yog siv nrog RTJ Flanges, whilst tsa ntsej muag ntsej muag gaskets siv cov mos muag lossis ib nrab ntawm cov gaskets. Muaj peb lub nplhaib sib koom ua ke lub zog tseem ceeb, cov no yog R, RX thiab BX; Peb yuav tsom rau R hom sib koom ua ke vim tias nws yog qhov ntau tshaj plaws.
R-hom RTJ Gaskets yog cov kab ncig nrog cov duab oval lossis octagonal zoo li profile / lub cev; Lub octagonal profile tau txais cov foob zoo tshaj plaws thiab yog cov qauv tsim tshiab. Ib tug zawj yog machined rau hauv lub ntsej muag ntawm ib tug rtj flange thiab cov txuam nrog gasket yog teeb tsa rau hauv qhov zawj no. Thaum lub flange yog sib sau ua ke, ob lub ntsej muag ua ntsej muag compress lub gasket kom txog thaum nws deforms thiab ib hlau rau hlau foob yog tsim. Yog hais tias lub flange yog sib dhos kom raug, ob lub mating RTJ flanges yuav tsum tsis txhob tuaj rau hauv kev sib cuag ib leeg
RTJ Gaskets feem ntau yog tsim los ntawm cov khoom me ntsis softer tshaj li ntawm Flange. Vim tias cov ntaub ntawv gasket yog softer, nws deforms ntawm qis dua siab dua li lub flangs, qhov no ua kom lub foob ua kom cov flanging deforming ncig lub gasket.
