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.
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.
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.
