我国电力工业发展概况。分析了国内高压锅炉管供需现状。对我国火力发电用高压锅炉管宏观需求进行了预测。分析了火力发电用高压锅炉管的微观特性,指出我国火力发电用高压锅炉管生产行业在新钢种开发、大直径特厚壁高压锅炉管热处理工艺以及产品性能稳定性方面,与钢管技术发达国家相比还存在着差距需要改进。
The development of electric power industry in China. The supply and demand situation of high pressure boiler tubes in China is analyzed. The macro demand of high pressure boiler tubes for thermal power generation in China is predicted. This paper analyzes the micro characteristics of high-pressure boiler tubes for thermal power generation, and points out that there is still a gap between China's high-pressure boiler tube production industry and developed countries in terms of new steel development, heat treatment process of large diameter and extra thick wall high-pressure boiler tubes, and product performance stability.
T91高压锅炉管所做的高温拉伸、持久强度、抗氧化性等试验成果,并就宝钢T91性能稳定性进行了讨论.试验表明,宝钢T91高压锅炉管性能稳定,可用于电站锅炉的制造.
The test results of T91 high pressure boiler tube, such as high temperature tensile strength, endurance strength and oxidation resistance, are discussed. The test shows that the performance of T91 high pressure boiler tube is stable and can be used in the manufacture of power station boiler.
可生产的产品品种包括油管、低中压锅炉管、高压锅炉管、流体输送用管、结构用无缝钢管等,产品规格为Ф60.0-114.3mm×4.5-12.0mm×6000-12000mm。
The products that can be produced include oil pipes, low and medium pressure boiler pipes, high pressure boiler pipes, pipes for fluid transmission, seamless steel pipes for structure, etc. the product specification is Ф 60.0-114.3mm × 4.5-12.0mm × 6000-12000mm.
