Kufotokozera Kwachidule:
Q355 zitsulo chitoliro ndi Chinese otsika aloyi mkulu mphamvu structural zitsulo chitoliro, amene m'malo Q345, kachulukidwe zakuthupi ndi 7.85 g/cm3.Malinga ndi GB/T 1591 -2018, Q355 ili ndi magawo atatu apamwamba: Q355B, Q355C ndi Q355D.
Chitoliro chachitsulo cha Q355 ndi aloyi otsika, chitsulo champhamvu kwambiri chomwe chimagwiritsidwa ntchito muzinthu zowotcherera zomwe zimathandizira kupsinjika ndi katundu wolemetsa.Q imatchula zokolola, pamene nambala 355 imasonyeza mphamvu zake zokolola.
Makhalidwe a Q355 Steel Pipe
Q355 zitsulo chitoliro ndi structural zitsulo ndi mphamvu zokolola za 345 MPa ndi kumakoka mphamvu 450 MPa.Ili ndi magwiridwe antchito owopsa komanso mphamvu zopondereza, zomwe zitha kugwiritsidwa ntchito popanga zombo zothamanga kwambiri zamagesi okhala ndi malita osakwana 500.Q355 imakhalanso ndi gawo loteteza la dzimbiri.
Kugwiritsa ntchito Chitoliro chachitsulo cha Q355
Chitoliro chachitsulo cha Q355 chili ndi zida zabwino zamakina, kutsekemera kwakukulu, komanso kukana kwa dzimbiri.Itha kugwiritsidwa ntchito kupanga ndi kupanga akasinja osungira mafuta, zotengera zothamanga kwambiri, ma boilers, zombo, malo opangira magetsi, ndi zina zambiri zonyamula katundu wambiri.
Kukula: 34mm-610mm.
WT: 3.5mm-50mm
Maonekedwe: Chozungulira.
Mtundu wopanga: Kutentha kotentha kapena Kutentha kwambiri.
Utali: Utali umodzi mwachisawawa / Kawiri mwachisawawa kutalika kapena ngati kasitomala akufunadi kutalika kwake ndi 12m
