Ukuhlolwa kwe-Hydrostatic
Ipayipi ukumelana nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi. Amajoyinti akudingeki ahlolwe i-hydrostatic inqobo nje uma izigaba zamapayipi ezisetshenzisiwe zihlolwe ngempumelelo.
Goba ukuhlolwa
Akukho mifantu ezokwenzeka kunoma iyiphi ingxenye yesiqeshana sokuhlola futhi akukho kuvulwa kwe-weld okuzokwenzeka.
Ukuhlolwa kokucaba
Indlela yokwamukela yokuhlolwa kokucaba izoba:
- EW amapayipi D<12.750 in:
- I-X60 ene-T 500in. Ngeke kube khona ukuvulwa kwe-weld ngaphambi kokuba ibanga phakathi kwamapuleti libe ngaphansi kwama-66% obubanzi bangaphandle bokuqala. Kuwo wonke amabanga nodonga, 50%.
- Epayipini eline-D/t> 10, akumele kuvuleke i-weld ngaphambi kokuba ibanga phakathi kwamapuleti libe ngaphansi kuka-30% we-diameter yasekuqaleni yangaphandle.
- Ukuze uthole abanye osayizi bheka ngokugcweleI-API 5Lukucaciswa.
Ukuhlolwa komthelela we-CVN kwe-PSL2
Osayizi abaningi bamapayipi e-PSL2 namabanga adinga i-CVN. Ipayipi elingenamthungo kufanele lihlolwe emzimbeni. Ipayipi elishiselwe kufanele lihlolwe emzimbeni, ukushiselwa kwamapayipi nendawo ethinteke ukushisa. Bheka ngokugcweleI-API 5Lukucaciswa kweshadi losayizi namabanga kanye namavelu wamandla amuncwa adingekayo.
