Seamless steel yeeb nkabe yog ib tug ntev steel sawb nrog ib tug hollow cross-section thiab tsis muaj seams nyob ib ncig ntawm. Vim nws qhov tshwj xeeb ntawm nws cov txheej txheem tsim khoom, nws muaj lub zog siab thiab zoo siab ua haujlwm. Lub seamless steel kav qhia lub sij hawm no muaj xws li ob yam ntaub ntawv thiab specifications: 15CrMoG qib, specification 325 × 14 thiab12Cr1MoVGqib, specification 325 × 10.

Cov yam ntxwv thiab kev siv ntawm15 CrMoGcev steel
15CrMoG yog chromium-molybdenum alloy steel, cov tshuaj tseem ceeb ntawm cov khoom siv xws li carbon (C), chromium (Cr), molybdenum (Mo), thiab lwm yam. Cov khoom siv no muaj lub zog siab, zoo oxidation tsis kam thiab kub tsis kam, tshwj xeeb tshaj yog nyob rau hauv kub thiab kub siab. Tsis tas li ntawd, 15CrMoG kuj muaj cov vuam zoo thiab kev ua haujlwm zoo.

Siv
Seamless steel kav ua los ntawm 15CrMoG yog tsuas yog siv rau kev kub siab thiab siab siab cov kav dej thiab cov khoom siv, thiab tau siv dav hauv cov teb hauv qab no:

Kev lag luam fais fab: boiler superheaters, reheaters, headers thiab cov kav dej loj hauv thermal fais fab nroj tsuag.
Kev lag luam tshuaj: piping systems rau high-temperature reactors nyob rau hauv cov khoom siv tshuaj.
Petroleum kev lag luam: high-temperature pipelines thiab tshav kub exchangers nyob rau hauv refineries.
Cov yeeb nkab steel no tuaj yeem tswj tau cov khoom zoo heev ntawm qhov kub thiab txias, thiab tshwj xeeb tshaj yog haum rau kev ua haujlwm ntev ntawm 500 ° C thiab 580 ° C.
Cov yam ntxwv thiab kev siv ntawm 12Cr1MoVG steel kav
12Cr1MoVG yog ib qho zoo chromium-molybdenum-vanadium alloy hlau uas muaj zog, zoo creep kuj, thiab muaj zog corrosion thiab oxidation kuj. Piv nrog rau 15CrMoG, nws ntxiv me me ntawm vanadium (V), uas ntxiv txhim kho nws qhov kub thiab txias tsis kam.
Siv
Seamless steel kav ua los ntawm 12Cr1MoVG feem ntau siv nyob rau hauv high-temperature thiab high-pressure ib puag ncig, thiab lawv daim ntawv thov ntau yam xws li:
Lub zog teb: high-temperature superheaters, reheaters thiab pipelines hauv thermal fais fab nroj tsuag thiab nuclear fais fab nroj tsuag.
Petrochemical kev lag luam: high-temperature thiab high-pressure chemical khoom thiab pipelines.
Boiler manufacturing: manufacturing high-pressure boiler raj rau cov khoom siv nrog kev ua haujlwm siab dua.
Cov yeeb nkab steel no yog tsim rau kev siv mus sij hawm ntev ntawm kev ua haujlwm kub tshaj 570 ° C thiab muaj zog heev creep kuj thiab ductility.
Lub 15CrMoG steel yeeb nkab nrog ib tug specification ntawm 325 × 14 thiab 12Cr1MoVG steel yeeb nkab nrog ib tug specification ntawm 325 × 10 muaj lawv tus kheej tsom. Ob leeg yog cov kav dej seamless steel yeeb nkab thiab tau siv dav hauv kev lag luam kub thiab siab siab xws li lub zog, petrochemicals, thiab tshuaj lom neeg. Nyob ntawm kev siv ib puag ncig, cov neeg siv tuaj yeem xaiv cov khoom siv hlau zoo dua kom tau raws li qhov xav tau ntau lawm.
