Uvavanyo lwe-hydrostatic
Umbhobho omele umelane novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld okanye umzimba wombhobho. Akunyanzelekanga ukuba ii-jointers zivavanywe nge-hydrostatic ukuba nje iindawo zombhobho ezisetyenzisiweyo zivavanywe ngempumelelo.
Uvavanyo lokugoba
Akukho mifantu iya kwenzeka nakweyiphi na inxalenye yesixhobo sovavanyo kwaye akukho kuvulwa kwe-weld kuya kwenzeka.
Uvavanyo lokuthamba
Iikhrayitheriya zokwamkelwa kovavanyo lokuthamba ziya kuba zezi:
- Iipayipi ze-EW D<12.750 kwi:
- I-X60 ene-T 500in. Akuyi kubakho kuvulwa kwe-weld ngaphambi kokuba umgama phakathi kweepleyiti ube ngaphantsi kwe-66% yobubanzi bokuqala bangaphandle. Kuzo zonke iiklasi kunye nodonga, yi-50%.
- Kwipayipi ene-D/t > 10, akufuneki kubekho kuvulwa kwe-weld ngaphambi kokuba umgama phakathi kweepleyiti ube ngaphantsi kwe-30% yobubanzi bangaphandle bokuqala.
- Ukuba ufuna ezinye iisayizi, jonga i-I-API 5Liinkcukacha.
Uvavanyo lwempembelelo ye-CVN kwi-PSL2
Iipayipi ezininzi zePSL2 ezinobukhulu kunye neendidi zifuna iCVN. Iipayipi ezingenamthungo kufuneka zivavanywe emzimbeni. Iipayipi ezidityanisiweyo kufuneka zivavanywe emzimbeni, kwipayipi ezidityanisiweyo nakwindawo echaphazelekileyo bubushushu. Jonga yonke into.I-API 5Liinkcukacha zetshathi yobukhulu kunye neeklasi kunye namaxabiso amandla afunxiweyo afunekayo.
