S355JR SSAW steel yeeb nkab yog dab tsi?
Qib zog ntawmS355JR SSAW steel yeeb nkabyog: yam tsawg kawg nkaus yield zog 355 MPa, yam tsawg kawg nkaus tensile zog 470-630 MPa, thiab phab ntsa thickness ntau ntawm 3 hli mus rau 16 hli.
Dab tsi yog qhov tso cai qhov sib txawv ntawm S355JR SSAW steel yeeb nkab?
RauS355JR SSAW steel yeeb nkab, permissible dimensional deviations feem ntau suav nrog phab ntsa thickness kam rau ua, qhov tsawg kawg nkaus phab ntsa thickness yuav tsum tsis pub tshaj 12.5% ntawm cov teev nominal phab ntsa thickness. Sab nraud txoj kab uas hla feem ntau tsis pub tshaj ± 1% ntawm cov txheej txheem sab nraud.
Dab tsi yog cov kauj ruam tseem ceeb ntawm S355JR SSAW kauv welded yeeb nkab?
Kauv welded yeeb nkab (SSAW / SAWH), kuj hu uakauv steel yeeb nkab: Tsawg- carbon steel lossis qis- alloy steel sawb yog dov rau hauv cov yeeb nkab khoob ntawm ib qho helix lub kaum sab xis (lub kaum sab xis), thiab tom qab ntawd cov yeeb nkab seam yog welded ua ke. Nws ua rau kev tsim cov loj - txoj kab uas hla steel kav los ntawm nqaim steel strips.
Dab tsi yog qhov zoo ntawm S355JR SSAW kauv welded yeeb nkab?
Customizable qhov ntau thiab tsawg kom tau raws li cov qauv tsim nyog rau txoj kab uas hla, phab ntsa thickness, thiab ntev; lub zog siab dua vim yog ob npaug - txheej vuam ua ib lub voj voog ncig ntawm cov yeeb nkab; superior pressure resistance, stress resistance, thiab kev sib txhuam tsis kam. Lub kauv band ho txhim kho lub zog ntawm cov qauv, nrog lub siab tsis kam 25% siab dua cov kav dej ntev ntev thiab ERW kav.
Nyob rau hauv tej yaam num engineering yog S355JR SSAW kauv welded yeeb nkab feem ntau siv?
S355JR SSAW kauv welded yeeb nkabyog dav siv nyob rau hauv cov roj thiab roj tsheb thauj mus los, kev siv dej thiab cov kav dej, cov txheej txheem engineering, thiab cov haujlwm ua haujlwm xws li tshuaj lom neeg thiab cua sov. Nws kuj tseem siv rau hauv pawg hauv paus engineering thiab hluav taws xob engineering rau cov kav xa dej.
