Seamless steel yeeb nkab (SMLS) feem ntau yog dov los ntawm cov pa roj carbon zoo tib yam thiab cov hlau alloy steel, feem ntau tsim, feem ntau yog siv los thauj cov yeeb nkab lossis cov khoom siv.
Cov pa roj carbon steel raj muaj qee qhov nyiaj ntawm carbon, silicon thiab manganese.
Nws tsis muaj lwm yam alloying ntsiab. Cov ntsiab lus silicon feem ntau tsis ntau tshaj 0.40%. Txhawm rau kom ntseeg tau cov tshuaj muaj pes tsawg leeg ntawm cov hlau thiab cov khoom siv kho tshuab, peb yuav tsum tswj cov ntsiab lus sulfur thiab phosphorus cov ntsiab lus hauv qab 0.035%. Ua li no peb tuaj yeem tsim cov pa roj carbon steel yeeb nkab zoo.
Carbon steel yeeb nkab classification
Tsawg carbon steel raj, cov ntsiab lus carbon tsawg dua li ntawm 0.25%. Lub siab tsim yog tsawg dua 10mpa rau cov roj, roj thiab roj, thiab kev tshaj tawm pej xeem.
Nruab nrab carbon steel shank, carbon cov ntsiab lus ntawm 0.25 ~ 0.60%, xws li 35 thiab 45 steel;
High carbon steel tube, cov ntsiab lus carbon ntau dua 0.60%. Hom hlau no feem ntau tsis siv rau hauv kev tsim cov yeeb nkab steel.
Cov txiaj ntsig ntawm carbon steel yeeb nkab
Cov yeeb nkab carbon steel cia siab rau kev hloov kho cov ntsiab lus ntawm cov pa roj carbon monoxide kom txuas ntxiv ntxiv dag zog rau cov khoom siv ntawm cov pa roj carbon steel yeeb nkab, yog li tsim cov yeeb nkab carbon steel sib txawv, uas tau txiav txim siab raws li cov ntsiab lus carbon.
Qee qhov tuaj yeem siv rau hauv kev tsim cov khoom siv tshuab thiab cov qauv tsim thiab kev sib kis cov kav dej, thiab lwm yam. Kuj tseem siv tau rau hauv kev ua liaj ua teb irrigation thiab dej txuag engineering, ntau yam kev siv.
Qhov sib txawv ntawm carbon steel kav thiab seamless steel yeeb nkab
1, Kub dov seamless steel yeeb nkab yog tsim los ntawm txoj kev drilling yam tsis muaj vuam kab. Qee lub sij hawm kom tau txais cov duab sib xws thiab qhov loj me.yuav tsum tau ntxiv rau hauv ib lub raj hauv kev ua haujlwm kub tom qab ua haujlwm txias. Round, square, tiaj tus, thiab lwm yam.
2, Seamless steel yeeb nkab yog cov yeeb nkab feem ntau siv hauv petrochemical ntau lawm. Tab sis cov yeeb nkab carbon steel siv ntau dua.
