Pou yon Flange Joint Klas 300 Lap dapre estanda ASME B16.5, isit la se dimansyon apwoksimatif yo an pous pou gwosè komen:
Gwosè tiyo nominal (NPS):Ranje soti nan 1/2 pous (DN 15) a 24 pous (DN 600) ak pi gwo.
Dyamèt deyò (OD):OD a varye ak NPS. Pa egzanp, OD yon bride 1/2-pous apeprè 4.25 pous, pandan y ap OD yon bride {24-pous anviwon 35.50 pous.
Dyamèt twou (BD):Dyamèt twou nan yon bride jwenti jwenti matche ak dyamèt anndan an (ID) nan tiyo a kote li tache. Li se tipikman menm jan ak gwosè tiyo nominal (NPS).
Epesè (T):Epesè bride jwenti a se relativman inifòm epi anjeneral koresponn ak epesè tiyo li itilize a.
Dyamèt mwaye (HD):Dyamèt mwaye a nan yon bride jwenti se tipikman pi gwo pase OD a pou pèmèt pou fasil Fitting sou tiyo a.
Longè an jeneral nan sant (LTH):Dimansyon sa a, ki se distans ki soti nan fas a nan bride a nan fen mwaye a, tou ogmante ak gwosè a nan bride la.
Epesè bride:Epesè bride a varye selon klas presyon an.
Dimansyon sa yo se apwoksimatif epi yo ka varye yon ti kras depann sou manifakti a ak kondisyon espesifik. Li esansyèl pou konsilte estanda ASME B16.5 oswa espesifikasyon manifakti a pou dimansyon egzak pou yon gwosè bride espesifik jwenti.
