Structural Steel Pipe
The dongosolo zitsulo chitoliro ali otentha - adagulung'undisa zitsulo chubu ndi welded zitsulo chubu. The seamless zitsulo chubu kwa dongosolo lagawidwa mitundu iwiri molingana ndi makonzedwe a "msokonezo chubu chitsulo dongosolo" (GB / t8162-2008) : otentha anagubuduza (kugudubuzika otentha) extrusion, kukulitsa) ndi kujambula kozizira (kugudubuza) .The awiri akunja otentha adagulung'undisa zitsulo chitoliro ndi 32-630mm ndi makulidwe khoma ndi 2.5-75mm.Kunja kwa chitoliro chachitsulo chozizira ndi 5-200mm ndipo makulidwe a khoma ndi 2.5-12mm.Welded zitsulo chitoliro amapangidwa ndi mbale zitsulo kapena zitsulo Mzere pambuyo crimping ndi kupanga, amene akhoza kugawidwa molunjika welded zitsulo chitoliro ndi ozungulira welded zitsulo chitoliro. -12.7mm motero, zomwe zimagwirizana ndi zomwe GB / t3793-2008. The welded zitsulo chitoliro kwa otsika-anzanu madzimadzi kayendedwe amatchedwanso wamba welded chitoliro, amene amadziwika kuti clark chitoliro.Mafotokozedwewo amafotokozedwa mu mm wa m'mimba mwake mwadzina, zomwe ziyenera kutsata zomwe GB/ t3091-2008 zoyendera zamadzimadzi otsika.
