First, SA106B seamless steel pipe introduction
SA106B seamless steel pipe is a kind of pipe widely used in high temperature flue gas and water vapor transportation, which belongs to the ASTM standard in the United States. It has the characteristics of good corrosion resistance, heat resistance and high strength, and can work stably in high temperature and high pressure environment for a long time. SA106B seamless steel pipe using high-quality carbon steel as the main raw material, after multiple processes of processing, its specifications, size, appearance and quality are in line with international standards.
Second, high temperature flue gas and water vapor requirements for pipes
The transportation of high-temperature flue gas and water vapor has very high requirements for pipes, and the following characteristics are required:
1. High temperature tolerance: can withstand the long-term effect of high temperature smoke and water vapor, without deformation, softening and embrittlement.
2. Corrosion resistance: It can resist the corrosion of acidic, alkaline and other chemical substances to ensure the service life of the pipe.
3. High strength: with high tensile strength and yield point, it can withstand the internal pressure and external load of the pipeline.
4. Sealing: the pipe connection must have good sealing performance to prevent the leakage of high temperature smoke and water vapor.
5. Stability: The pipe must have good thermal stability and creep resistance to ensure long-term stable operation in high temperature environment.
