Siv BS4504 tus qauv, muajphajflanges, weld caj dab flanges, plam ntawm flanges, threaded flange thiabqhov muag tsis pom flange, thiab lwm yam. Txog cov hom flanges, yuav qhia lawv qhov tshwj xeeb qhov siab thiab lwm yam ntsiab lus Phaj Flanges (Code 101)
Phaj hom ca vuam flange (chemical standard HG20592, teb chaws standard GB/T9119, mechanical JB/T81): yooj yim kom tau cov ntaub ntawv, yooj yim rau siv, tsis tshua muaj nqi thiab dav siv. Txawm li cas los xij, nws cov rigidity yog qhov tsis zoo, yog li nws tsis tuaj yeem siv rau hauv cov khoom siv thiab kev thov, cov nplaim hluav taws kub thiab tawg cov txheej txheem piping tshuab. Cov tshuab no xav tau kev tawg thiab lub tshuab nqus tsev siab dua, thiab yog qhov txaus ntshai heev. Hom sealing nto yog tiaj thiab convex.
Threaded flange yog ib qho uas tsis yog-welded flange, uas yog txuas nrog cov yeeb nkab threaded los ntawm kev ua lub puab qhov ntawm flange rau hauv cov yeeb nkab xov. Piv nrog cov vuam flange los yog lub taub qab vuam flange, threaded flange muaj cov yam ntxwv ntawm kev yooj yim installation thiab txij nkawm, thiab tuaj yeem siv rau cov kav dej uas tsis tso cai rau qhov chaw vuam. Alloy steel flange muaj lub zog txaus, tab sis nws tsis yooj yim rau vuam, lossis qhov kev ua haujlwm vuam tsis zoo, threaded flange kuj tuaj yeem xaiv. Txawm li cas los xij, thaum cov yeeb nkab kub hloov pauv sai lossis qhov kub siab tshaj 260 ° C tab sis qis dua - 45 ° C, nws raug nquahu kom tsis txhob siv threaded flange kom tsis txhob to.
Flange npog tseem hu ua dig muag flange, dig muag phaj. Qhov no yog flange tsis muaj qhov nyob nruab nrab, uas yog siv los kaw cov yeeb nkab ntsaws. Qhov kev ua haujlwm no yog tib yam li cov welded sib koom ua ke thiab threaded yeeb nkab cap. Qhov txawv yog tias qhov muag tsis pom flange thiab threaded yeeb nkab cap tuaj yeem raug tshem tawm txhua lub sijhawm, tab sis lub taub hau vuam tsis tuaj yeem raug tshem tawm. Muaj ntau hom sealing nto, xws li tiaj tus, convex, concave thiab convex, tenon thiab zawj nto thiab annular kev twb kev txuas.
American standard flanges yog cov khoom uas txuas cov kav dej rau cov kav dej thiab cov yeeb nkab kawg. American standard butt-welded flanges yog forged thiab cam khwb cia nyob rau hauv ob txoj kev. American standard butt welding flange tuaj yeem muab faib ua American standard butt welding flange thiab non-cecked American standard butt welding flange raws li nws lub caj dab. American standard butt vuam flange muaj ob lub phaj flange thiab flange gaskets. Flange washers yog bolted ua ke kom tiav kev sib txuas. American standard flange muaj qhov, thiab bolts txuas ob flanges nruj nreem. Lub flange yog kaw nrog gasket.
