Ukuhlolwa kwe-hydrostatic
Ipayipi elimelana nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo wokushisela noma umzimba wepayipi. Ama-jointer akudingeki ahlolwe nge-hydrostatic uma nje izingxenye zepayipi ezisetshenzisiwe zihlolwe ngempumelelo.
Ukuhlolwa kokugoba
Akukho mifantu okumelwe ivele kunoma iyiphi ingxenye yengxenye yokuhlola futhi akukho kuvulwa kwe-weld okumelwe kwenzeke.
Ukuhlolwa kokuthamba
Izindlela zokwamukelwa kokuhlolwa kokuthambekela kufanele zibe:
- Amapayipi e-EW D<12.750 in:
- I-X60 ene-T 500in. Akumelwe kube nokuvulwa kwe-weld ngaphambi kokuba ibanga eliphakathi kwamapuleti libe ngaphansi kuka-66% wobubanzi bangaphandle bokuqala. Kuzo zonke izinhlobo nodonga, 50%.
- Kumapayipi ane-D/t > 10, akufanele kube nokuvulwa kwe-weld ngaphambi kokuba ibanga eliphakathi kwamapuleti libe ngaphansi kuka-30% wobubanzi bangaphandle bokuqala.
- Ukuze uthole amanye amasayizi bheka okugcweleI-API 5Limininingwane.
Ukuhlolwa komthelela we-CVN kwe-PSL2
Amapayipi amaningi e-PSL2 osayizi kanye namazinga adinga i-CVN. Amapayipi angenamthungo kufanele ahlolwe emzimbeni. Amapayipi ahlanganisiwe kufanele ahlolwe emzimbeni, endaweni yokushisela amapayipi kanye nendawo ethinteke ukushisa. Bheka okugcweleI-API 5Limininingwane yeshadi lobukhulu namabanga kanye namanani wamandla adingekayo.
