SANS 1123 Carbon Steel Stainless Steel Foged Weld Neck Flange

Zogulitsa Zambiri

Chiyambi cha Zamalonda

SANS 1123 ndi muyezo wa flange woperekedwa ndi National Bureau of Standards of South Africa, womwe umaphatikizapo mitundu yosiyanasiyana ya ma flanges, ndi kuwotcherera khosi.flangesndi imodzi mwa njira zomwe zimagwiritsidwa ntchito polumikizana.

Necked butt welding flange ndi njira yolumikizira yowotcherera flange kumapeto kwa chitoliro.Amadziwika ndi khosi lozungulira kuzungulira flange, ndipo amagwiritsidwa ntchito kwambiri polumikizana ndi mapaipi othamanga kwambiri kapena otentha kwambiri.Amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana chifukwa cha kulumikizana kwake kolimba, kusindikiza bwino, komanso kunyamula mwamphamvu.

TheZithunzi za SANS 1123imatchula mitundu yosiyanasiyana ya ma flanges opangidwa ndi khosi, kuphatikizapo PN6-PN100 flanges, Type 01 flanges, Type 11 flanges, ndi Type 05 flanges.

PN6-PN100 flanges amagawidwa molingana ndi milingo yosiyanasiyana ya kukakamiza.PN6 imasonyeza kuti kupanikizika kwakukulu kwa flange ndi 6 bar, ndipo PN100 imasonyeza kuti kuthamanga kwambiri ndi 100 bar.Kusankhidwa kwa ma flange okhala ndi miyeso yosiyana siyana kuyenera kutsimikiziridwa malinga ndi momwe ntchito ikugwiritsidwira ntchito.

Khosi lozungulira la mtundu wa 01 flange ndi mainchesi a chitoliro ndizofanana, ndipo ndizoyenera kulumikizana ndi zitoliro zing'onozing'ono.Khosi lozungulira la mtundu wa 11 flange ndi bwalo limodzi lalikulu kuposa kukula kwa chitoliro, ndipo limatha kupirira kupanikizika kwambiri.Ndizoyenera kulumikiza mapaipi othamanga kwambiri.Mtundu wa 05 flange uli ndi mainchesi ofanana ndi chitoliro, koma mkati mwake ndi wokulirapo, ndikupangitsa kuti ikhale yoyenera kulumikiza zida zokhala ndi miyeso yayikulu.

Posankha akhosi welded flange, m'pofunikanso kuganizira zinthu monga kusankha flange zinthu ndi kupanga.Nthawi zambiri, zinthu za flange zimatha kukhala chitsulo cha kaboni, chitsulo chosapanga dzimbiri, chitsulo cha aloyi, ndi zina zambiri. Njira yopangira zinthu iyenera kutsata miyezo yoyenera kuonetsetsa kuti kulumikizana kuli bwino komanso chitetezo.
