低中壓鍋爐用電焊鋼管的質(zhì)量分析

Quality Analysis of Electric Welded Steel Pipe for Low/Medium Pressure Boiler Service

摘要: 通過對哈爾濱鋼管廠所生產(chǎn)的低中壓鍋爐用電焊鋼管,在材料質(zhì)量、幾何尺寸、常溫及高溫性質(zhì)、金相組織、實用加工性等方面的試驗,結(jié)合相關(guān)標(biāo)準(zhǔn)進行綜合分析與比較。結(jié)果表明:該廠生產(chǎn)的低中壓鍋爐用電焊鋼管的各項性能優(yōu)于或達到GB 3087-1999和YB 4102-2000標(biāo)準(zhǔn)規(guī)定的指標(biāo),鋼管焊縫與母材均有良好的加工性,鋼管的高溫性能滿足電站鍋爐的質(zhì)量要求。

Abstract: Based on relevant tests and applicable standard, comprehensive analysis and comparison relating to the electric welded steel tube for low/medium pressure boiler service are made in terms of material quality, geometric dimension performance under ambient/elevated temperatures, metallographic structure and workability, etc., showing that all the performance/property target values of the said welded tube produced by Harbin Steel Tube Plant have been up to or even better than the requirements as specified in GB 3087-1999 and YB 4102-2000, particularly the good workability both of the weld seam and the base metal and the tube's hi-temperature performance which meets the quality requirements as set for the thermal power plant boiler.
