Welded Steel Tubes

Hom hlau no feem ntau yog smelted nyob rau hauv lub converter los yog qhib-hearth rauv. Nws cov ntaub ntawv tseem ceeb yog molten hlau thiab seem hlau. Cov sulfur thiab phosphorus cov ntsiab lus nyob rau hauv cov hlau yog siab dua li ntawm high-zoo carbon structural steel. Feem ntau, sulfur tsawg dua lossis sib npaug rau 0.050% thiab phosphorus tsawg dua lossis sib npaug li 0.045%. Cov ntsiab lus ntawm lwm cov hlau alloy tau coj mus rau hauv cov hlau los ntawm cov khoom siv raw, xws li chromium, npib tsib xee, thiab tooj liab, feem ntau tsis tshaj 0.30%.

Carbon steel yeeb nkab yog ib tug kauv seam steel yeeb nkab ua los ntawm steel kauj, extruded nyob rau hauv chav tsev kub thiab welded los ntawm tsis siv neeg ob-xaim submerged arc vuam txheej txheem. Lub kauv steel yeeb nkab pub cov sawb mus rau hauv lub welded yeeb nkab chav tsev, thiab tom qab tau dov los ntawm ntau lub chais, lub sawb yog maj dov los ua ib tug round tube billet nrog ib tug qhib qhov sib txawv, thiab ob kawg ntawm lub weld yog flush.

Me me txoj kab uas hla carbon steel welded yeeb nkab adopts ncaj seam vuam, thiab loj txoj kab uas hla welded yeeb nkab adopts kauv vuam. Raws li cov ntaub ntawv sib txawv thiab kev siv, nws tau muab faib ua welded steel yeeb nkab rau kev thauj mus los hauv kuv cov kua dej, galvanized welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab, thiab hluav taws xob welded steel yeeb nkab rau siv conveyor cov menyuam.

Q215 welded yeeb nkab yog siv los thauj cov kua dej tsawg. Feem ntau, welded kav yog ua los ntawm Q195A, Q215A, thiab Q235A steel. Lwm cov hlau me me uas yooj yim rau vuam tuaj yeem siv tau. Cov kav hlau yuav tsum tau ua dej siab, khoov, flattening thiab lwm yam kev ntsuam xyuas, thiab muaj qee qhov kev xav tau rau qhov zoo. Feem ntau, qhov ntev ntawm kev xa khoom yog 4-10m, thiab qhov ntev ruaj khov (lossis ntau qhov ntev) kev xa khoom feem ntau yuav tsum tau. Cov specifications ntawm welded kav yog qhia nyob rau hauv nominal txoj kab uas hla (mm los yog nti). Lub nominal txoj kab uas hla txawv ntawm qhov tseeb txoj kab uas hla. Raws li cov txheej txheem phab ntsa thickness, welded kav tau muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab. Cov kav hlau yog muab faib ua threaded thiab tsis yog xov raws li daim ntawv ntawm cov yeeb nkab kawg.
