Imfuneko yoVavanyo
Uvavanyo lweHydrostatic
Umbhobho wokumelana novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld okanye umzimba wombhobho. Izihlanganisi akufuneki zivavanywe i-hydrostatic zibonelela ngamacandelo emibhobho asetyenzisiweyo avavanywe ngempumelelo.
Bend uvavanyo
Akukho zintanda ziya kwenzeka kuyo nayiphi na inxalenye yesiqwenga sovavanyo kwaye akukho kuvulwa kwe-weld kuya kwenzeka.
Uvavanyo lokucaba
Iikhrayitheriya zokwamkelwa kovavanyo lokucaba iya kuba:
- Imibhobho ye-EW D<12.750 kwi:
- X60 nge T 500in. Akusayi kubakho ukuvulwa kwe-weld phambi kokuba umgama phakathi kweepleyiti ungaphantsi kwe-66% ye-diameter yokuqala yangaphandle. Kuwo onke amabakala kunye nodonga, i-50%.
- Ngombhobho nge-D / t> 10, akuyi kubakho ukuvulwa kwe-weld ngaphambi kokuba umgama phakathi kwamacwecwe ungaphantsi kwe-30% ye-diameter yangaphambili yangaphandle.
- Ngobunye ubungakanani bhekisa kokupheleleyoAPI 5Liinkcukacha.
Uvavanyo lwempembelelo yeCVN yePSL2
Uninzi lwemibhobho yePSL2 kunye namabanga afuna i-CVN. Umbhobho ongenamthungo kufuneka uvavanywe emzimbeni. Umbhobho odityanisiweyo kufuneka uvavanywe emzimbeni, umbhobho weld kunye nendawo echaphazelekayo kubushushu. Jonga ngokupheleleyoAPI 5Liinkcukacha zetshati yobungakanani kunye namabanga kunye namaxabiso afunxayo afunekayo amandla.
