Ngaba uyazi ukuba zeziphi iintlobo zeeflange ezifakwe kwi-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 kumbi kakhulu, ngoko ke 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 usicaba kunye ne-convex.

I-flange ene-threaded yi-flange e-non-welded, edityaniswe kumbhobho odibeneyo ngokucubungula umngxuma ongaphakathi we-flange kwintambo yombhobho. Xa kuthelekiswa ne-flange ye-welding flat okanye i-butt welding flange, i-flange ene-threaded ineempawu zofakelo olufanelekileyo kunye nokugcinwa, kwaye ingasetyenziselwa imibhobho engavumeli i-welding yentsimi. I-alloy steel flange inamandla okwaneleyo, kodwa akukho lula ukuyidibanisa, okanye ukusebenza kwe-welding ayilungile, i-flange ene-threaded nayo inokukhethwa. Nangona kunjalo, xa ubushushu bombhobho butshintsha ngokukhawuleza okanye ubushushu bungaphezulu kwama-260 ° C kodwa bungaphantsi kwe-45 ° C, kuyacetyiswa 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 naleyo yodibaniso oludityanisiweyo kunye nomphetho wombhobho odityanisiweyo. 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 ineepleyiti 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.
