Q345B Square Tube

ityhubhu yesikwere ye-Q345B, ityhubhu yesikwere ye-16Mn, ityhubhu yesikwere ye-Q345B, ityhubhu yesikwere, ityhubhu yesikwere, ityhubhu yesikwere esingenamthungo, ityhubhu yesikwere yentsimbi, ityhubhu yesikwere esikwere, ityhubhu ye-q345b yesikwere, ityhubhu etyebileyo enodonga, ityhubhu ye-Q345C yesikwere, isikwere sensimbi engenasici. Imibhobho yentsimbi yoxande, imibhobho yentsimbi enoxande engenamthungo kunye nezinye iimveliso zemibhobho yesikwere.

I-Q345B ityhubhu yesikwere iveliswa ngokwemigangatho yesizwe ye-GBT 6728-2002 epholileyo epholileyo yecandelo lentsimbi yobukhulu, imilo, ubunzima kunye nokuphambuka okuvumelekileyo kwesakhiwo.Yenziwe ngentsimbi ye-Q345B yentsimbi emva kokulungiswa kunye nokuqengqeleka.I-tube ye-square ye-Q345B yenziwe ngezinto ze-Q345B (i-alloy ephantsi), ehluke kakhulu kwi-tube yesikwere eqhelekileyo kwizinto ezibonakalayo (Q195, Q215, Q235).Ngokuqhelekileyo, i-Q345B strip steel (i-alloy ephantsi) ayipakishwanga., I-Flattened, i-crimped, i-welded ukwenza i-tube ejikelezayo, kwaye emva koko ifakwe kwi-tube yesikwere ukusuka kwiphubhu ejikelezayo kwaye inqunyulwe ubude obufunekayo.Ubude obuqhelekileyo buziimitha ezi-6, kwaye inani elikhulu leemitha ezili-12 linokucutshungulwa ngokweemfuno zabathengi.Ngokubanzi, ubungakanani obuncinci bungamaqhekeza angama-50 kwipakethi nganye, kwaye ubungakanani obukhulu bungamaqhekeza ama-4 kwaye ubunzima bulawulwa malunga neetoni ezi-3.Iityhubhu ze-Q345B ubukhulu becala ziyi-80MM * 80MM-500MM * 500MM kwiinkcukacha ezinkulu kwisitokhwe, kwaye ubukhulu yi-3MM-16MM.
