S355JR yog qhov qis- alloy siab- lub zog cov qauv hlau ua raws li European tus qauv EN10025-2. Nws muaj qhov zoo weldability thiab toughness, ua rau nws tshwj xeeb tshaj yog haum rau cov qauv uas yuav tsum tau hnyav loads. Lub npe "JR" qhia tau hais tias cov hlau muaj qee qhov kev cuam tshuam toughness, ua rau nws haum rau siv nyob rau hauv qhov kub thiab txias.
S355JR Steel Pipe Basic Specifications thiab Qauv
S355JR steel kav muaj nyob rau hauv ntau yam specifications thiab qauv, feem ntau suav nrog cov hauv qab no:
1. Thickness range: Feem ntau ntawm 3mm mus rau 100mm, yoog raws li kev xav tau ntawm engineering sib txawv.
2. Qhov dav dav: Cov qauv dav dav yog 1.5 meters, 2 meters, thiab 3 meters, nrog rau kev cai dav muaj rau cov kev cai tshwj xeeb.
3. Ntev ntev: Ntev ntev li ntawm 6 meters mus rau 12 meters, ua tau raws li ntau yam kev tsim kho.
4. Kev kho saum npoo: Kub- dov, txias- dov, galvanized, thiab lwm yam kev kho mob muaj nyob rau ntawm kev thov.
Qhov kev sib txawv ntawm cov kev qhia tshwj xeeb thiab cov qauv no tso cai rau S355JR cov kav dej steel kom hloov tau yooj yim hauv ntau qhov haujlwm engineering, ua tau raws li tus kheej xav tau ntawm cov neeg siv khoom.
Cov yam ntxwv ntawm S355JR Steel Pipe
S355JR steel yeeb nkab tau ruaj ntseg qee qhov kev lag luam vim nws qhov kev ua tau zoo dua. Nws cov yam ntxwv technical muaj xws li:
1. Lub zog muaj zog: Nws lub zog tawm los yog ntau dua lossis sib npaug ntawm 355MPa, haum rau kev coj tus kheej hnyav.
2. Zoo Toughness: Nws tuav tau zoo toughness txawm nyob rau hauv qis - ib puag ncig kub, haum rau siv nyob rau hauv hnyav huab cua.
3. Muaj zog Weldability: Txawm tias welded manually los yog txiav, qhov zoo ntawm welded sib koom ua ke tuaj yeem lav.
4. Corrosion Resistance: Kev kho deg tsim nyog tuaj yeem txhim kho nws cov corrosion kuj.
