Ukunyamezelana

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 kuvulwa kwe-weld phambi kokuba umgama phakathi kweepleyiti ungaphantsi kwe-66% ye-diameter yangaphandle yokuqala. 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 kwi-API 5L epheleleyo.

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 kwi-API 5L epheleleyo yenkcazo yetshathi yobungakanani kunye namabanga kunye namaxabiso afunekayo afunxa amandla.
