Q235B Longitudinal HighFrequency Welded Steel Yeeb Nkab
Q235B Longitudinal High - zaus} zaus welded steel yeeb nkab khoom lus qhia
Q235B Longitudinal High - zaus welded steel yeeb nkab {3 ces txiav rau hauv welded steel kav ntawm qhov yuav tsum tau ntev. Cov khoom no siv cov tawv nqaij daim tawv thiab cov nyhuv sib thooj ntawm lub xeev siab dua mus rau qhov ua tiav ntawm kev ua haujlwm ntawm cov hlau ua kom sov, ua tiav cov qauv weld txuas ntxiv. Nws cov txiaj ntsig lub zog tsis pub tsawg dua 235MPA, thiab nws cov pa loj} {8} Kev tsim kho thaj chaw, siab thiab qhov tseeb siab. Nws yog dav siv nyob rau hauv qis - Kev siv cov dej hluav taws xob kom siab, kev txhawb nqa cov qauv kev tsim kho, thiab kev tsim cov tshuab kev tsim dav. Cov khoom no conforms rau GB / T 3091 tus qauv thiab tuaj yeem kho nrog kub- daph muaj kev kho raws li qhov yuav tsum tau ua ntawm cov kev cai pabcuam.
Cov Khoom Siv Neeg Kho Tshuab
| Qhov ntsuas tau ua tiav | Cov Qauv Yuav Tsum Tau | Kev ntsuas ntsuas qhov tseem ceeb |
|---|---|---|
| Yield zog (RP0.2) | Ntau dua los yog sib npaug rau 235 MPa | 255 ~ 310 MPa |
| Lub zog tensile (RM) | 375 ~ 500 MPA | 390 ~ 460 MPa |
| Elongation tom qab pob txha lov (a) | Ntau dua los yog sib npaug rau 20% | 25% ~ 35% |
| Plhaw kev kuaj | Compressed rau h =2 / 3D, tsis muaj kab nrib pleb pom. | Tsim nyog. |
| Weld Lub Zog | Tsis qis dua li cov khoom siv hauv paus. | Sib npaug los yog me ntsis siab dua hauv lub zog tshaj li cov khoom siv hauv paus. |
Kev kho deg ntawm Q235b Longitudinal welded siab - zaus watded steel kav
Cov kev kho deg ntawm q235b ntev welded siab - zaus} NTIM}- dip galvanizing txheej txheem. Cov txheej txheem suav nrog cov kauj ruam pretreaticated xws li alkaline degreasing, hydrochloric acid pickling, raws li los ntawm kub}}- 460 degree. Qhov kawg no ua ib qho txheej txheej ua tiav rau saum npoo av, muaj cov zinc {{}}}} Ick txheej thiab ib txheej huv si zinc txheej. This treatment ensures that the zinc coating on the steel pipe surface is no less than 275g/㎡ (standard requirement), with uniform thickness and strong adhesion, effectively resisting atmospheric corrosion and electrochemical corrosion, and significantly extending service life. Tsis tas li ntawd, kev tawm tsam txhim kho xws li eposion kev kho xws li epoxy resin electrostatic txau lossis polyethylene txheej yuav siv tau raws li xav tau. Cov txheej txheej no muab kev tiv thaiv ntev dua rau cov kav hlau loj los ntawm kev tiv thaiv kab mob Cathodic ntawm lub cev.
Txog Peb
Gnee Steel pab pawg yog feem ntau nrog nyob rau hauv thoob ntiaj teb kev lag luam export, muaj 18 xyoo kev paub hauv daim teb no. Peb cov khoom siv hlau hluav taws xob ua haujlwm (Welded Steel kav, kauv cov kav dej ncaj, thiab cov kab ke, thiab muaj cov neeg tau txais txiaj ntsig zoo nkauj.
