Seamless Pipe Performance in High-Temperature Applications
Date:2025-03-21View:212Tags:seamless pipe manufacturers,api 5l pipe,lsaw pipe
High-temperature seamless pipes must withstand thermal expansion, oxidation, and creep deformation over extended periods.
Key Materials for High-Temperature Seamless Pipes:
-
A335 P91 (Modified 9Cr-1Mo Steel): High creep resistance, used in boiler tubes.
-
Inconel 625: Superior oxidation resistance, applied in gas turbine exhaust systems.
-
Hastelloy C-276: Handles extreme acidic environments in high temperatures.
Challenges of High-Temperature Service:
-
Carburization: Carbon diffusion can lead to brittle pipe structures.
-
Thermal Fatigue: Repeated heating/cooling cycles cause microcracking.
-
Grain Growth: At extreme temperatures, microstructure coarsening reduces strength.
Applications:
-
Superheater tubes in power plants.
-
Catalytic reforming reactors in petrochemical industries.
