API 5L X42 Steel Yeeb Nkab

Nrog rau txoj kev loj hlob ntawm cov yeeb nkab steel phaj technology thiab kev vam meej ntawm cov yeeb nkab txoj kev thiab vuam tshuab, daim ntawv thov Scope ntawm cov yeeb nkab welding kav yog maj expanding, tshwj xeeb tshaj yog cov zoo ntawm vuam kav nyob rau hauv lub loj-gauge ntau yog brighter thiab ntub dej, ua ke nrog cov nqi yam. , welding kav tau nyob hauv txoj haujlwm tseem ceeb hauv cov kav dej, txwv txoj kev loj hlob ntawm seamless stainless hlau kav. Xyoo 2004, cov yeeb nkab seamless ntau lawm yog kwv yees li 400000 tons, thiab qib steel suav nrog x42 - 70. ntau yam yog onshore pipelines thiab subsea pipelines.

microalloy cua sov, tus nqi tsim khoom ntawm stainless hlau seamless kav yog ho siab dua li cov kav hlau welded, thiab nrog rau cov qib steel nce, xws li cov pa roj carbon sib npaug kev txwv ntawm cov yeeb nkab steel siab tshaj x80, cov pa seamless steel yeeb nkab txheej txheem nyuaj. kom tau raws li cov neeg siv khoom xav tau; Txhua 12cr1mov alloy yeeb nkab ntau lawm cog yog nqa tawm kev tshawb fawb ua hauj lwm los txhim kho corrosion kuj ntawm nws cov kav dej thiab stabilizing kev siv nyob rau hauv qis thiab kub ib puag ncig.
