Butt welded reducer yog ib qho ntawm cov yeeb nkab reducer, cov yeeb nkab reducer tseem hu ua lub taub hau loj thiab me me yog ib qho ntawm cov yeeb nkab fittings, siv rau kev sib txuas ntawm ob txoj kab sib txawv. Raws li cov duab sib txawv, nws tuaj yeem muab faib ua RC concentric reducer thiab RE eccentric reducer.
Reducer, tseem hu ua lub taub hau loj thiab me, yog ib qho ntawm cov yeeb nkab fittings, siv hauv kev tsim cov kav dej rau kev sib txuas ntawm ob txoj kab sib txawv, raws li cov duab sib txawv tuaj yeem muab faib ua RC concentric reducer thiab RE eccentric reducer. Txo / sizing lub taub hau yog ib hom yeeb nkab fittings siv rau cov yeeb nkab txoj kab uas hla, feem ntau cov txheej txheem siv yog txo txoj kab uas hla nias, expansion nias los yog txoj kab uas hla txo ntxiv txoj kab uas hla expansion nias, thiab stamping kuj yuav siv tau rau ib co me me txo cov yeeb nkab specifications.
Reducers tuaj yeem muab faib ua carbon steel raws li cov khoom siv: (20#, A3, Q235, Q235A, Q235B, 20G, 16Mn, Q345, Q345R, ASTM A234WPB, ASTM A105, thiab lwm yam); Tus Hlau Stainless: (304, 304L, s30408, s31608, {} cr164, 91CR21, 022cr17NI12 , thiab lwm yam); Alloy steel: (16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910, 15CrMo, 12Cr2Mo1, A335P22, St45.8/III., A10bB, thiab lwm yam); Cov hlau tshwj xeeb: (TP310S, 904L, Incoloy800, Incoloy825, Incoloy600, Incoloy625, thiab lwm yam); Duplex stainless hlau: (F51, S31803, S2205, F53, 2507, S32750, F55, 2607, S32760, thiab lwm yam).

Butt weld reducer daim ntawv thov: Thaum tus nqi ntws ntawm cov kua hauv cov kav dej hloov pauv, xws li nce lossis txo qis, thiab cov kev xav tau ntawm cov dej ntws tsis hloov ntau, cov yeeb nkab reducer yuav tsum tau siv; Nyob rau hauv lub twj tso kua mis inlet, kom tsis txhob cavitation, yuav tsum tau ib tug reducer raj; Nyob rau hauv kev sib tshuam nrog cov twj paj nruag, xws li cov ntsuas ntws thiab cov tswj valve, txhawm rau koom tes nrog kev sib tshuam ntawm cov twj paj nruag, nws tseem yuav tsum tau siv lub reducer. Tam sim no, feem ntau ntawm cov kav dej sib txuas yuav tsum tau siv lub taub hau reducer, feem ntau yog siv hauv roj av, tshuaj lom neeg, roj, nkev, cov kav dej, cov tshuab hydraulic, thiab lwm yam.
