Ko te tikanga o te whakatauranga karaehe o te karaehe raupapa B16: ka whakaingoatia te whakatauranga karaehe i runga i te ahotea e whakaaetia ana (8750PSI) o A105, WCB 1.1 rauemi roopu i raro i te 454°C me te whakatauranga pehanga i runga i te 60.3MP:

• P1=(10S/8750)*Pr≤Pc

P1 – whakatauranga pehanga o te flange i runga i te pāmahana, pae.
S – uara ahotea e whakaaetia ana o te papanga flange, MPa.
Pr – flange Uara akomanga.

Pc – Pae whakatauranga teitei teitei.

Mo te flange o te rauemi 150# me te ahotea whakaaetia o 100MPa, e waatea ana (10*100/8750)*150=17Bar=1.7MPa.He rite ki te ahotea whakaaetia o 150# flange, tona pehanga mahi whakaaetia ko 1.7%.

Paearu mo te whakatau i te horahanga Bolt o te flange rangatū B16:
Mo te flange me te hononga tinana takirere:

• AB *7000Psi≥Ag*Pc-> AB *120MPa≥Ag*Pg

Ab – tapahanga whiti o te raka
Te horahanga o te mata whakapiri i roto me te whanui o waho (tae atu ki te waahi mau i roto i te diameter o roto).
Pc – Koeke karaehe o te flange
Ko te kaha o te kawe o te pou kia kaua e iti iho i te whakatau ko te pehanga o roto kei roto i te diameter o waho o te mata hiri o te peeke ina he rite te taumahatanga whakaaetia ki te 120MPa.Mo te hononga flange, ko te a193b7 bolt me ​​te kaha tuku o te 105ksi (724mpa) te nuinga o te whakamahi, a ko te take haumaru o te hoahoa pou ko ns ≥ 6. Na reira, he nui ake te waahi pou o te ASME B16.5 flange i tera o ASME VIII I kore. - flange paerewa.Na te nui o te tuwhene o te raka, he maha nga wa karekau te kaha o te flange ina tatauhia kia rite ki te tauira.Engari i roto i te meka, he haumaru te flange, na reira i kii ai te tohu ko te flange kua tohua kia rite ki te paerewa flange o B16.5 kaore e taea te tatau i runga i te tauira.

Ko te tikanga o te Sch: Ko te Sch he whakapotonga o nga umper apiti mo te rahi paipa.Ko te tikanga ka whakareatia te ōwehenga o te pehanga hoahoa punaha paipa ki te taumahatanga e whakaaetia ana i te pāmahana hoahoa ki te 100 0 me te uara i muri i te whakaawhiwhi.Hei tauira, ki te 1MPa te pehanga hoahoa me te pehanga e whakaaetia ana o te paipa he 100Mpa, me whakamahi te paipa me te 1/100 100 0=10 me te> Sch.10.Mo nga paipa whanui, ko te taumahatanga e whakaaetia ana o nga rawa whanui he 100Mpa, ka taea e Sch.80 te kawe i te 8MPa, ka taea e Sch.160 te mau 16MPa, me etahi atu, he tohutoro whanui mo te whiriwhiri i te Sch.
