Ngokuqhelekileyo banobude obumalunga neemitha ezi-6 ubude.Xa uyala umbhobho, umsebenzisi kufuneka alinganise i-diameter yangaphandle nangaphakathi yombhobho.Ukuba ubukhulu bodonga bubalulekile, umbhobho unokuyalelwa nge-OD kunye nodonga okanye i-ID kunye nodonga.
Ngokwesiseko sensimbi ephezulu ye-carbon structural, ipayipi yensimbi ye-hydraulic yongezwa ngokufanelekileyo kunye nenye okanye ngaphezulu kwezinto ezixutywayo zokuphucula amandla, ukuqina kunye nokuqina kwentsimbi.
Uhlobo lombhobho we-hydraulic steel ngokuqhelekileyo olwenziwa ngokucinywa kufuneka lubekwe phantsi konyango lokushisa kweekhemikhali kunye nokuqina kobushushu bomhlaba.Xa kuthelekiswa nomgangatho ophezulu we-carbon structural steel, insimbi yolwakhiwo ineempawu ezilungileyo zoomatshini, kwaye ubukhulu becala iqengqeleke ibe yintsimbi engqukuva, yesikwere, nesicaba, eyinxalenye ebalulekileyo yolwakhiwo loomatshini okanye oomatshini.Kodwa ukuxhathisa ukunxiba kunye nokusika ukuchasana kungcono kakhulu kunentsimbi engenasici.
Zimbini iindidi zamabakala ezinto eziphathekayo, i-ST52.4 kunye ne-ST37.4.I-ST52.2 yityhubhu yamandla aphezulu, oku kuthetha ukuba inoxinzelelo oluphezulu oluvumelekileyo lokusebenza ngokunciphisa ubukhulu bodonga lwetyhubhu kunye neziphumo kubunzima benkqubo ephantsi.
