Uvavanyo lwe-hydrostatic
Umbhobho wokumelana novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-wel okanye umzimba wombhobho. Amajoyine akufuneki ukuba avavanywe i-hydrostatic ukubonelela ngamacandelo emibhobho esetyenzisiweyo avavanywa ngempumelelo.
Uvavanyo lwe-Bend
Akukho zibuko ziya kwenzeka nakweyiphi na inxalenye yesiqwenga sovavanyo kwaye akukho kuvulwa kwe-weld.
Uvavanyo lokungafihli
Iikhrayitheriya zokwamkelwa kovavanyo lokuthambeka luya kuba:
- Imibhobho ye-eW d <12.750 kwi:
- I-X60 nge-t00in. Akuyi kubakho kuvulwa kwe-weld ngaphambi komgama phakathi kweepleyiti zingaphantsi kwe-66% yedaya lentsusa. Kuwo onke amabakala nodonga, iipesenti ezingama-50.
- Ngombhobho nge-D / T> 10, Akuyi kubakho kuvulwa kwe-weld ngaphambi komgama phakathi kweepleyiti zingaphantsi kwe-30% yobubanzi bayo bangaphandle.
- Obunye ubukhulu bhekisa ngokupheleleyoAPI 5Lukucaciswa.
Uvavanyo lwempembelelo ye-CVN ye-PSL2
Uninzi lwemibhobho ye-PSL2 ye-PSL2 kunye namaBanga afunekayo kwi-CVN. Umbhobho ongenamthungo uza kuvavanywa emzimbeni. Imibhobho ye-Welding iya kuvavanywa emzimbeni, i-well ye-pipe kunye nendawo echaphazelekayo yobushushu. Bhekisa ngokupheleleyoAPI 5LUkucaciswa kwetshathi yobukhulu kunye namabakala kwaye kuyafuneka amaxabiso anexabiso lamandla.
