JIS G3444 STK500 Scaffolding Yeeb Nkab
JIS G3444 Txheem Txheej txheem cej luam
• JIS G3444 yog cov kev qhia txog kev siv tshuaj rau cov roj carbon hlau rau cov qauv kev lag luam dav dav (JIS), qhov tseeb tshaj plaws yog JIS G3444: 2015. Tus qauv no qhia txog cov tshuaj lom neeg, cov neeg kho mob txhua yam, cov kev xav tau ntawm cov yeeb nkab steel, thiab yog qhov haum rau kev tsim kho, tshuab, scaffolding thiab lwm yam qauv txheej txheem.
Stk500, yog ib qho ntawm cov qib kawm tau hais hauv cov qauv, yog lub siab carbon steel tsim rau cov khoom siv thauj khoom, tshwj xeeb tshaj yog rau cov papes.
Cov Khoom Siv Khoom
Tshuaj Muaj Tshuaj
• Pa roj carbon (c): tsawg dua lossis sib npaug rau 0. 24%
• silicon (si): tsawg dua lossis sib npaug rau 0. 35/30%
• manganese (mn): {0. 3% -1. 3%
• Phosphorus (p), leej faj (s): ob qho tsawg dua lossis sib npaug nrog 0. 04%.
Cov Khoom Siv Neeg Kho Tshuab
• Lub zog tensile: ntau dua lossis sib npaug nrog 500 MPa
• Pais lub zog: ntau dua los yog sib npaug rau 355 MPa
• elongation (Δ5): ntau dua los yog sib npaug rau 17%
• Lub Hardness (HBS): 123-321.
• Corrosion Kuj: Tsim los ntawm Annking Dub (Dub Annealing) Oxidation Txheej, nrog qee yam kev tiv thaiv corrosion.
Qhov ntev thiab kev ua kom muaj kev puas tsuaj
• Txheej txheem uas lub taub ntau lawm: feem ntau 48.6mm (txheem scaffold raj loj), lwm cov lus qhia tshwj xeeb tuaj yeem raug kho rau 610 hli.
• Daim phab ntsa tuab: Feem ntau 1. {{}}. 3 hli, kwv yees li 25% tsawg dua li ib txwm yog ib txwm muaj hlab (xws li Stk500).
• Ntev: Feem ntau 5. {8-6. 5m, txhawb nqa qhov loj loj txiav.
• Cov cai zam rau: Thia thia sab nraud 0. 5%, phab ntsa tuab ± 10%.
Daim Ntawv Thov
Scaffolding: Raws li ib tus qauv txhawb nqa ib ntus, STK500 steel yeeb nkab tseem txhim kho kev nyab xeeb thiab ua rau nws lub zog siab thiab lub zog qaim thiab lub teeb yuag.
• Kev tsim kho txhua yam: siv rau cov neeg ua tshuab thav duab, conveying tshuab thiab lwm yam ntawm cov kabmob-cov kabmob.
• Infrastructure: Railway Graneedrail, Choj Pab nyiaj thiab lwm cov duab tiv thaiv huab cua tsis kam.
• Cov phiaj xwm thoob ntiaj teb: exported rau New Zealand, Nyablaj thiab lwm qhov chaw sib txuas thiab lwm qhov chaw.
Ntau lawm thiab kuaj
• Cov Txheej Txheem Ntau Lawm: Loj zaus ncaj rau sab vuam (ERW) lossis seamless cov txheej txheem, ua ke nrog kev ua kom zoo nkauj nruj.
• Kuaj cov qauv: suav nrog X-ray kuaj, ultrasonic kuaj xyuas, ntsuas kev ua si nrog JIS G3444, EN10219, API 5L thiab lwm tus qauv thoob ntiaj teb.
Daim ntawv pov thawj yuav tsum muaj: Nyiv Jis ntawv pov thawj thiab EU PED, Singapore FPC thiab lwm yam ntawv pov thawj thoob ntiaj teb.
Piv nrog lwm cov ntaub ntawv
• Stk500 vs. STK400 / STK490:
Lub Stk500 muaj lub zog siab dua siab dua (500MPA) tshaj li lub Stk400 (400MPA) thiab Stk490 (490MPA), uas yog qhov haum rau cov khoom lag luam siab dua.
• Nrog cov yeeb nkab tsoos scaffolding: siv daim nyias nyias phab ntsa (1.8mm) los txo qhov hnyav los ntawm kev kho cua sov, cov yeeb yam tag nrho zoo dua li cov yeeb nkab steel hlau.
