Q355 Hot Rolled Seamless Steel Pipe

Tlhaloso e Khutšoanyane:

Pipe ea tšepe ea Q355 ke phala ea tšepe e tlase ea Sechaena e nang le matla a phahameng a sebopeho sa tšepe, e nkileng sebaka sa Q345, boima ba thepa ke 7.85 g/cm3.Ho ea ka GB / T 1591 -2018, Q355 e na le maemo a 3 a boleng: Q355B, Q355C le Q355D.

Q355 tšepe pipe ke motsoako o tlase, tšepe e matla e phahameng e sebelisoang meahong e cheselitsoeng e tšehetsang khatello ea maikutlo le meroalo e boima.Q e supa ntlha ea tlhahiso, ha palo ea 355 e bonts'a matla a eona a tlhahiso.

Litšobotsi tsa Pipe ea tšepe ea Q355

Pipe ea tšepe ea Q355 ke tšepe ea sebopeho e nang le matla a tlhahiso ea 345 MPa le matla a matla a 450 MPa.E na le ts'ebetso e tšabehang ea ts'ebetso le matla a hatellang, a ka sebelisetsoang ho etsa likepe tsa khatello e phahameng ea khase e nang le tlase ho lilithara tse 500.Q355 e boetse e na le lera le sireletsang la ho hanyetsa mafome.

Tšebeliso ea Pipe ea tšepe ea Q355

Pipe ea tšepe ea Q355 e na le thepa e ntle haholo ea mochini, ho cheseha ho hoholo, le ho hanyetsa ho hoholo ha kutu.E ka sebelisoa ho etsa le ho hlahisa litanka tsa polokelo ea peterole, likepe tse nang le khatello e phahameng, li-boilers, likepe, liteishene tsa motlakase le likarolo tse ling tse ngata tsa meralo e phahameng.

Boholo: 34mm-610mm.

WT: 3.5mm-50 limilimithara.

Sebopeho: Round.

Mofuta oa tlhahiso: Ho chesa kapa ho chesa haholo.

Bolelele: Bolelele bo le bong bo sa reroang/ Bolelele bo habeli bo sa reroang kapa joalo ka ha kopo ea 'nete ea moreki ke 12m
