(1) Uxhulumaniso lwe-node lufanelekile kwi-welding ngokuthe ngqo, kwaye akufuneki ukuba idlule kwi-node plate okanye ezinye iindawo zokudibanisa, ezigcina abasebenzi kunye nezinto eziphathekayo.

(2) Xa kuyimfuneko, ikhonkrithi inokugalelwa kumbhobho ukuze yenze inxalenye edibeneyo.

(3) Iimpawu zejometri zecandelo lombhobho zilungile, udonga lombhobho ngokuqhelekileyo luncinci, izinto zecandelo zisasazwa malunga ne-centroid, i-radius ye-gyration yecandelo likhulu, kwaye inobunzima obuqinileyo be-torsional;njengokunyanzeliswa, ukunyanzeliswa, kunye necandelo lokugoba i-bidirectional, yayo Umthamo wokuthwala uphezulu, kwaye ukuthe tye kwemibhobho eyenziwe ngokubanda kunye nokuchaneka kwemilinganiselo ye-cross-sectional ingcono kunezo ze-cross-sections ezivulekileyo ezivulekileyo.

(4) Imbonakalo intle ngakumbi, ngakumbi i-truss yombhobho eyenziwe ngamalungu ombhobho wentsimbi, akukho xhulumaniso oludityanisiweyo oludityanisiweyo, kwaye imvakalelo yanamhlanje yomelele.

(5) Ngokweempawu ze-anti-hydrodynamic, i-cross-section ye-tube ejikelezayo ingcono, kwaye umphumo womoya kunye nokuhamba kwamanzi kuyancipha kakhulu.Icandelo lombhobho loxande lifana namanye amacandelo avulekileyo kule nkalo.

(6) Imibhobho yentsimbi enobubanzi obukhulu iye yavala amacandelo anqamlezayo;xa i-avareji yobukhulu kunye ne-cross-sectional area iyafana, indawo ebonakalisiweyo malunga ne-50% ukuya kwi-60% yecandelo elivulekileyo elivulekileyo, elinenzuzo ekukhuseleni ukubola kwaye inokugcina izinto zokugqoka.
