Nto Kho: Tsis ua tiav, pleev xim, roj, galvanzation, 3pe, fbe coated ......

Txheej txheem tsim khoom:

JIS G3466 kav hlau tuaj yeem tsim los ntawm vuam (piv txwv li vuam, tsis siv neeg arc vuam) los yog seamless cov txheej txheem. Kev kho cua sov tsis yog feem ntau ua.

Qhov loj me thiab kev ua kom ntev:

(Shs) square raj loj Ntau: 20 × 20 hli {2}} × × 350 mm, phab ntsa thickness 1.2 hli {6}}. 5 hli.

(RHS) Rectangular Raj loj ntau: 30 × 20 hli {2}} × × × 200 hli, phab ntsa {6} mm.

Qhov seem ntev:

Kev kam yog ± 1.5 mm thaum lub sab ntev yog tsawg dua lossis sib npaug rau 100 mm, kev ua siab ntev yog ± 1.5% thaum sab ntev yog> 100 mm.

Kev khwv nyiaj txiag thiab lub zog zoo dua:

Piv rau cov tawv hlau, JIS G3466 steel yeeb nkab muaj tib txoj kev khoov thiab torsional lub zog thiab yog sib zog hauv qhov hnyav, ua rau nws muaj cov khoom siv nyiaj txiag.

Daim ntawv thov

Cov kav hlau steel raws li tau hais tseg hauv Jis G3466 feem ntau yog siv rau cov hom phiaj dav dav, suav nrog tab sis tsis txwv rau cov ntawv thov hauv qab no:

Kev tsim kho thiab Civil engineering:

JIS G3466 Cov kav hlau hlau feem ntau yog siv hauv kev tsim qauv hauv tsev, txuas hniav, muaj nroj tsuag, cov qauv kev txhawb nqa ntawm cov tsev siab, thiab lwm yam.

Tshuab thiab khoom siv tsim khoom:

Nws tuaj yeem siv los tsim cov thav ntawv, txhawb nqa thiab lwm cov txheej txheem txheej txheem ntawm cov tshuab thiab khoom siv.

Cuab Yeej Siv Hauv Qhov Av:

Nws tseem dav siv nyob rau hauv cov av infrastructure-ntsig txog teb, xws li Guardrivail, Choj pawg thiab lwm yam xwm txheej.

Tubrog Nkoj Thiab Automotive Qhov:

Cov qauv hlau txheem hlau kuj tseem siv tau rau hauv kev tsim cov nkoj ntawm cov qauv sab hauv cov qauv thiab chaw tsheb.

Lwm Yam Siv:

Xws li kev txhawb nqa ntawm cov khoom siv hnub ci, cov ntsuas ntawm cov vaj tse steel qauv, thiab lwm yam.

JIS G3466 HOLLOW PIPES

Qhov Zoo

JIS G3466 Hlau Yeeb (Jis G3466 Txheem Hlau Hlau) muaj cov hauv qab no txawv ntawm lwm cov hlau:

Siab zog &

Zoo tougnness

JIS G3466 Txheem Hlau Hlau tau muab faib ua STKR400 thiab STKR490 Qeb Qeb Ob, feem ntau, muaj zog sib txawv thiab kev sib txawv. Lub zog tensile thiab tawm lub zog ntawm stkr400 yog ntau dua los yog sib npaug nrog 400 MPa thiab ntau dua lossis sib npaug. Lub zog tensile ntawm stkr490 yog ntau dua los yog sib npaug rau 490 MPa, thiab cov txiaj ntsig lub zog yog ntau dua lossis sib npaug rau 325 MPa. Lub zog no siab thiab kev ua kom nruj ua rau nws zoo nyob rau hauv cov ntawv thov cov ntawv thov.

Siab sab downensional qhov tseeb

Cov kav dej ntawm cov qauv no ua tau zoo nyob rau hauv cov nqe lus ntawm qhov tseeb raug. Piv txwv li, thaum ib sab ntev yog tsawg dua los yog sib npaug rau 100 hli, lub siab ntev tsuas yog ± 1.5 hli; Thaum sab ntev yog> 100 mm, lub thev naus laus zis yog ± 1.5%. Qhov kev tswj hwm qhov ntsuas tau zoo tshaj plaws ua rau nws kom tau zoo dua ua tau raws cov qauv tsim qauv thiab kev tsim khoom lag luam.

Thoob ntiaj teb cov qauv sib xyaw

JIS G3466 Cov kav kav kav muaj qee cov qauv thoob ntiaj teb (xws li}}, en {}, en}}

Zoo Weldability

JIS G3466 cov yeeb nkab steel muaj cov qauv zoo heev weldability, tshwj xeeb tshaj yog stkr400 qib uas yog qhov zoo tagnrho rau cov txheej txheem vuam. Qhov no ua rau nws yoog tau yooj yim thiab txuag tau thaum tsim thiab teeb tsa.

Kev khwv nyiaj txiag thiab lub teeb ci ntsa iab

Piv rau cov tawv hlau, JIS G3466 steel yeeb nkab muab lub zog tib yam thaum tau sib dua, ua nws cov khoom siv nyiaj txiag. Qhov no tsis tsuas yog txo cov nqi thauj khoom thiab cov nqi nruab, tab sis kuj txo cov khoom siv uas siv.

Ntau yam kev tsim khoom lag luam

Cov kav dej txheem tuaj yeem tsim los ntawm ntau yam txheej txheem, suav nrog hluav taws xob vuam, tsis siv neeg arc vuam, lossis cov txheej txheem seamless. Cov hau kev tsim khoom lag luam no ua rau nws tau ua kom tau raws li cov xwm txheej sib txawv thiab cov neeg siv khoom xav tau.

Corrosion tsis kam thiab Deg Kho

JIS G3466 kav hlau tuaj yeem yog galvanized raws li cov neeg siv khoom, yog li txhim kho lawv cov corrosion tsis kam. Qhov no muab nws lub neej pabcuam kom zoo dua nyob rau hauv cov chaw ntub lossis kev xeb ib puag ncig.

Ntau yam ntawm cov ntawv thov

Vim nws lub zog siab, qhov chaw raug cai thiab kev ua haujlwm zoo, JIS G3466 Cov Khoom Siv Hlau, kev tsim khoom lag luam, thauj khoom, nkoj xa khoom thiab lwm daim teb.
