A53 Welded Yeeb Nkab Tshuaj Ntsuam Xyuas
Cov khoom soj ntsuam ntawm A53 welded steel yeeb nkab muaj xws li: qhov tsis xws luag, qhov loj, qhov hnyav, tensile test, flattening test, galvanized txheej hnyav, galvanized txheej uniformity, galvanized txheej nto zoo, galvanized txheej adhesion, thiab lwm yam. rau koj qhov kev xav tau tiag tiag.
Cov kev xav tau ntawm qhov project
- Ntsis qhov xwm txheej saum npoo: Sab hauv thiab cov kav dej sab hauv ntawm A53 ERW kav, hlawv, lap vuam, thiab lwm yam tsis xws luag ntawm phab ntsa tuab tom qab sib tsoo tau raug tso cai. Cov kab mob no yuav tsum tau tshem tawm tag nrho, thiab cov phab ntsa qis dua ntawm lub vev xaib tshem tawm yuav tsum tsis txhob tsawg tshaj li cov nqi tsawg kawg nkaus los ntawm phab ntsa thickness sib txawv. Lwm qhov tsis xws luag hauv zos uas nws qhov tob tsis tshaj qhov kev sib txawv ntawm phab ntsa tuab tau tso cai.
- Lub zog tensile: Lub zog tensile ntawm A53 steel kav yuav tsum tsis txhob tsawg dua 370MPa.
- Lub zog qis zog: Qhov kev ntxhov siab tsawg kawg nkaus ntawm A53 steel yeeb nkab qauv thaum lub sij hawm yielding, ignoring lub sij hawm pib tshwm sim, yuav tsum tsis txhob tsawg tshaj li 235MPa.
- Elongation tom qab pob txha lov: tom qab cov kev ntxhov siab tau raug tshem tawm, qhov sib piv ntawm Elongation mus rau tus thawj Gauge ntev ntawm A53 cov yeeb nkab steel hlau yuav tsum tsis pub tsawg tshaj 15%.
- Flattening kev ua tau zoo: Thaum qhov kev ncua deb ntawm ob daim hlau yog 2/3 ntawm sab nraud txoj kab uas hla ntawm A53 carbon steel yeeb nkab, cov kab nrib pleb lossis cov kab nrib pleb tsis raug tso cai ntawm qhov vuam. Thaum qhov kev ncua deb ntawm ob daim hlau yog 1/3 ntawm sab nraud ntawm cov yeeb nkab steel, cov kab nrib pleb lossis cov kab nrib pleb tsis raug tso cai rau lwm qhov tshwj tsis yog cov vuam. Txuas ntxiv mus kom txog thaum cov yeeb nkab phab ntsa haum. Delamination lossis hlau overburning yog tsis tso cai thaum lub sij hawm tag nrho cov txheej txheem flattening.
- Galvanized Txheej Nyhav: Thaum ntsuas cov txheej txheej ntawm cov pa roj hmab ntawm cov yeeb nkab sab hauv thiab sab nraud ntawm cov yeeb nkab sab hauv thiab sab nraud yuav tsum tsis pub tsawg tshaj 300g / m².
- Kev sib txuam ntawm zinc txheej: A53 cov yeeb nkab ntawm A53 tsis tshwm sim tom qab tau muab raus rau hauv lub tooj liab sulfate daws rau 5 lub sijhawm sib law liag.
- Adhesion ntawm Zinc Txheej: tom qab A53 cov pa roj carbon hlau tau kuaj cov yeeb nkab tau tas li, cov qauv tsis pub muaj zinc txheej tev xim.
- Nto zoo ntawm galvanized txheej: galvanized txheej nyob rau sab hauv thiab sab nrauv ntawm A53 steel yeeb nkab yuav tsum ua kom tiav. Tsis muaj cov pob dub lossis npuas uas tsis tau coated nrog zinc raug tso cai. Cov chaw me me thiab cov zinc nodules hauv zos raug tso cai.
