Xav Tau Kev Xav Tau RauYeeb Nkab Flange Forgings(suav nrogtiv thaivthiabdov daim).
1.Qeb thiab kev xav tau ntawmZam txim(suav nrogforged thiab cov ntaub) Yuav tsum tau ntsib cov cai ntawm JB4726-4728.
2.Nominal siab PN 0.25 MP 1.0 MPA carbon hlau thiab usteneric stainlessKev muag tshuaj hlautso cai siv qib ⅰ zam txim.
3.Ntxiv rau cov kev cai hauv qab no, nominal siab ntawm PN 1.6 MPA zam rau 6.3 MPA yuav ua raws li ⅱ qib lossis theem siab ⅱKev Zam Txim Theem.
4.Hauv ib qho ntawm cov hauv qab no yuav tsum ua raws li qhov yuav tsum tau ua ntawm ⅲ thiabZam txim: (1) nominal siab pn acuity 10.0 mpaFlange Forging; (2) chromium-molybdenumKev muag tshuaj hlauNrog nominal siab pn> 4.0MPA; (3) FerriticKev muag tshuaj hlauNrog nominal siab PN> 1.6MPA thiab kev ua haujlwm kub ≤-20 ℃.

Pob pobvuam nrog caj dab, tiaj vuam nrog caj dab, Qhov (socket) vuamthiabxov flangefeem ntau yog tsim los ntawm kev zam txim lossisForging RollingCov txheej txheem.When Steel Phaj lossis Tshooj Hlau siv, cov cai hauv qab no yuav tsum tau ua kom tiav:
1.Cov phaj hlau yuav tsum tau kuaj los ntawm Ultrasonic tsis muaj kev cuam tshuam tsis xws luag;
2.Nws yuav tsum tau txiav mus rau hauv ib daim hlab ntawm cov yob raws li cov hlau, thiab welded rau hauv lub tog raj kheej ntawm lub nplhaib.Veb yuav tsum tsis txhob ncaj qha machinedflanges nrog caj dab;
3.Tag nrho nkag mus weld yuav tsum tau saws rau pob tw weld ntawm lub nplhaib;
4.Lub pob tw weld ntawm lub nplhaib yuav tsum tau kho cua sov thiab ua kom muaj kev pom kub thiab ultrasonic kom tau raws li cov chav kawm uas kuv xav tau ntawm JB4730.
