Do you know which types of flanges are included in BS4504?

Ukusebenzisa umgangatho we-BS4504, kukhoipleyitiiiflange, weld intamo flanges, tyibilika kwiiflange, iflange enemisonto kwayeiflange eyimfama, njl. Malunga nezi ntlobo zeeflange, ziya kuzisa uxinzelelo lwazo oluthile kunye nezinye iinkcukacha I-Plate Flanges (Code101)

I-Plate uhlobo lwe-flange ye-welding flange (i-chemical standard HG20592, i-standard standard ye-GB / T9119 yesizwe, i-JB / T81 yoomatshini): kulula ukuyifumana imathiriyeli, kulula ukuyenza, ixabiso eliphantsi kunye nokusetyenziswa okubanzi.Nangona kunjalo, ukuqina kwayo kubi kakhulu, ngoko ayinakusetyenziselwa ukubonelela kunye nemfuno, iinkqubo zemibhobho yenkqubo yeekhemikhali ezinokutsha kunye neziqhushumbisi.Ezi nkqubo zifuna ugqabhuko-dubulo kunye ne-vacuum ephezulu, kwaye ziyingozi kakhulu.Uhlobo lomphezulu wokutywina lusicaba kunye ne-convex.

I-flange ene-threaded yi-flange e-non-welded, edityaniswe kumbhobho odibeneyo ngokucubungula umngxuma ongaphakathi we-flange kwintambo yombhobho.Xa kuthelekiswa neflange ye-welding flat okanye i-butt welding flange, i-flange ene-threaded ineempawu zofakelo olufanelekileyo kunye nokugcinwa, kwaye ingasetyenziselwa imibhobho engavumeli ukuwelda intsimi.I-alloy steel flange inamandla okwaneleyo, kodwa akukho lula ukuyidibanisa, okanye ukusebenza kwe-welding ayilungile, i-flange ene-threaded nayo inokukhethwa.Nangona kunjalo, xa iqondo lokushisa lombhobho litshintsha ngokukhawuleza okanye iqondo lokushisa liphezulu kune-260 ° C kodwa lingaphantsi kwe-45 ° C, kucetyiswa ukuba ungasebenzisi i-flange ene-threaded ukuphepha ukuvuza.

Isigqubuthelo seflange sikwabizwa ngokuba yi-blind flange, ipleyiti eyimfama.Le yiflange engenamngxuma phakathi, esetyenziselwa ukutywina iplagi yombhobho.Lo msebenzi uyafana nalowo wekhonkco elidityanisiweyo kunye nekhonkco lombhobho ophothiweyo.Umahluko kukuba i-flange eyimfama kunye ne-threaded pipe cap ingasuswa nanini na, kodwa intloko ye-welding ayikwazi ukususwa.Kukho iintlobo ezininzi zeendawo zokutywina, ezibandakanya i-flat, i-convex, i-concave kunye ne-convex, i-tenon kunye ne-groove surfaces kunye nemiphezulu yokudibanisa i-annular.

Iiflange ezisemgangathweni zaseMelika zizinto ezidibanisa iipayipi kwimibhobho kunye neziphelo zemibhobho.Iiflange ze-butt-welded eziqhelekileyo zaseMelika zenziwe kwaye zenziwe ngeendlela ezimbini.I-American standard butt welding flange inokohlulwa ibe yi-welding standard ye-American butt welding flange kunye ne-non-necked American standard butt welding flange ngokwemiqathango yentamo yayo.I-American butt welding flange iquka iipleyiti ezimbini zeflange kunye neegasket zeflange.Iiwasha zeflange zibotshelelwa kunye ukuze kugqitywe uqhagamshelo.I-Flange esemgangathweni yaseMelika inemingxuma, kwaye iibholiti zidibanisa iiflange ezimbini ngokuqinileyo.I-flange ivalwe nge-gasket.
