Q355 Hot Rolled Seamless Simbi Pipe Featured Image

Tsanangudzo Pfupi:

Q355 simbi pombi iChinese yakaderera alloy yakakwirira simba structural simbi pombi, iyo yakatsiva Q345, zvinhu density iri 7.85 g/cm3.Maererano GB/T 1591 -2018, Q355 ine 3 mhando mazinga: Q355B, Q355C uye Q355D.

Q355 simbi pombi isimbi yakaderera, yakakwirira-yakasimba simbi inoshandiswa muzvivakwa zvakasungwa zvinotsigira kushushikana uye mitoro inorema.Iyo Q inonongedza poindi yegoho, nepo nhamba 355 inoratidza simba regoho rayo.

Hunhu hweQ355 Steel Pipe

Q355 simbi pombi isimbi yekugadzira ine goho simba re345 MPa uye tensile simba re450 MPa.Iine terrific processing performance uye compressive simba, iyo inogona kushandiswa kugadzira yakakwirira-kumanikidza gasi kumanikidza midziyo ine isingasviki 500 malita.Q355 zvakare ine dura rekudzivirira rekudzivirira ngura.

Kushandiswa kweQ355 Steel Pipe

Q355 simbi pombi ine yakanakisa mechaniki zvivakwa, yakakura weldability, uye yakakura corrosion kuramba.Inogona kushandiswa kugadzira uye kugadzira matangi ekuchengetera peturu, midziyo yekudzvanya, mabhailers, ngarava, zviteshi zvemagetsi, uye zvimwe zvakawanda zvakakura-mutoro zvikamu zvechimiro.

Saizi: 34mm-610mm.

WT: 3.5mm-50 mm.

Chimiro: Round.

Rudzi rwekugadzira: Kupisa kwakatenderedzwa kana Kupisa kwakashandiswa.

Kureba: Kureba kumwechete zvisina kurongeka / Kaviri kusarongeka kureba kana sechikumbiro chaicho chemutengi max kureba ndeye 12m

Kururamisa

Post annealing, zvinhu zvinopfuudzwa nemuchina wekutwasanudza nomwe kuti uwane kutwasanuka kwemachubhu.

Eddy current

Post kutwasanuka, chubhu yega yega inopfuudzwa nemuchina wazvino weeddy kuona kuti pane pakatsemuka uye humwe hurema.Machubhu chete anodarika eddy current anokodzera kuendesa kune vatengi.

Kupedza

Imwe neimwe chubhu inozorwa mafuta asingadzivirirwe mafuta kana kuti varnished yekudzivirira pamusoro uye corrosion inodzivirira sezvinodiwa nevatengi, imwe neimwe chubhu inovharwa nepurasitiki end caps kudzivirira kukuvadzwa mukufambisa, yekumaka uye specs zvinoiswa uye zvinhu zvagadzirira kutumirwa. .

Application

Q355 Inopisa Yakatenderedzwa Kabhoni simbi mapaipi asina musono anoiswa zvakanyanya mumudziyo wenyukireya, gasi kutakurwa, petrochemical, kuvaka ngarava uye maindasitiri ebhaira, ane hunhu hwekupokana kwakakwira kusanganiswa neakakodzera makina.
