Stainless hlau flange lub tshuab nqus tsev foob

Muaj cov roj hmab ntsaws ruaj ruaj, hlau ntsaws ruaj ruaj thiab cov kua nplaum sib nqus. Ntawm lawv, cov ntsaws ruaj ruaj hlau tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub tshuab nqus tsev siab, tab sis lawv muaj qhov tsis zoo hauv qab no: cov hlau ntsaws ruaj ruaj tsis zoo elasticity, yuav tsum muaj kev sib khi zoo, tsis muaj kev rov siv dua, thiab yuav tsum muaj siab roughness thiab qhov tseeb ntawm flange sealing nto thiab riam npoo. . , Lub thermal expansion coefficient ntawm lub nplhaib sealing thiab cov khoom flange yog qhov sib txawv heev, uas yog ib qho yooj yim ua rau lub zos deformation thiab ua rau huab cua to.

Cov yeeb nkab fittings muaj ob qhov zoo tshaj plaws:

Thawj yog tias nws tuaj yeem hloov qee yam khoom siv, thiab sib zog dua li cov khoom siv, castings, thiab forged structural qhov chaw, txuag cov ntaub ntawv; Qhov thib ob yog tias nws tuaj yeem txuag cov txheej txheem, txiv neej-teev, thiab txo cov nqi ua haujlwm piv nrog cov khoom siv machined.

Nkag siab qhov zoo ntawm kev kub siab txo cov yeeb nkab fittings

Qhov zoo ntawm cov yeeb nkab reducer high-pressure yeeb nkab fittings yuav tsum tau raws li qhov yuav tsum tau ntawm lub teb chaws tus qauv tam sim no "Steel Butt Welded Seamless Yeeb Fittings" GB / T 12459-2005, thiab lub roundness ntawm lub reducer yuav tsum tsis txhob ntau tshaj 1. feem pua ​​​​ntawm sab nraud txoj kab uas hla ntawm qhov kawg, thiab qhov tso cai sib txawv Nws yog ± 3 hli; qhov tso cai sib txawv ntawm tus reducer loj yuav tsum ua tau raws li qhov yuav tsum tau muaj ntawm Table 4.2.2-3.

Muaj ntau ntau hom kev kub siab txo cov yeeb nkab fittings, tab sis dab tsi yog hom tseem ceeb? Peb feem ntau tuaj yeem ntsib nrog lawv hauv lub neej niaj hnub. Kev siv cov yeeb nkab fittings loj heev, thiab muaj ntau hom yeeb nkab fittings. Cov yeeb nkab yog qhov tsim nyog raw khoom rau cov yeeb nkab fittings. Txawm li cas los xij, muaj ntau txoj hauv kev rau cov yeeb nkab fittings, tsuav yog nws yog cov txheej txheem ua tshuab, nws tuaj yeem siv tau.

Lub caj dab flanges tau muab faib ua caj dab tiaj vuam flanges thiab nruj pob tw vuam flanges

Lub taub qab vuam flange kev twb kev txuas yog tsim los ntawm 1 gasket, 2 taub qab vuam flanges thiab ob peb bolts thiab ceev. Cov yeeb nkab txoj kab uas hla thiab phab ntsa tuab ntawm qhov sib koom kawg ntawm lub taub qab vuam flange yog tib yam li cov yeeb nkab yuav tsum tau welded, thiab ob lub kav dej yog welded ua ke. Thaum lub thickness ntawm lub caj dab taub qab vuam flange tshaj lub thickness ntawm lub taub qab-welded steel yeeb nkab los ntawm ntau tshaj 1 hli, lub flange Qhov ncaj seem yuav tsum tau thinned nyob rau hauv lub puab txoj kab uas hla, thiab txoj kab nqes ntawm lub thinned seem. yuav tsum tsawg dua los yog sib npaug rau 1: 3.
