Boiler steel pipes are high-temperature and high-pressure resistant seamless steel tubes designed for steam, gas, and fluid transmission in boilers and heat exchangers. With tensile strength typically between 410 and 640 MPa and excellent oxidation resistance up to 450 °C, they ensure reliable performance in power plants, pressure vessels, and thermal systems.

Surface Treatment Methods of Boiler Steel Pipe
• Hot Rolling: Produces a dense oxide layer and enhances the pipe's strength and durability for high-temperature applications.
• Cold Rolling: Improves surface finish and dimensional accuracy, providing a smoother and more uniform appearance.
• Polishing: Removes surface imperfections and enhances corrosion and wear resistance.
• Pickling Surface: Involves acid cleaning to eliminate oxide scales and rust, leaving a clean, metallic surface.
• Smooth Surface: Offers excellent resistance to corrosion and oxidation, suitable for demanding boiler environments.
