Flanged forged steel gate valve SG41-F were used for a steam pipeline of power plant in Penang, Malaysia

Project Requirements:

The customer requires a flanged gate valve suitable for a high-pressure, high-temperature steam pipeline operating at 160 bar and 450°C. The valve must possess excellent pressure-bearing capacity and corrosion resistance. Additionally, zero leakage and a long service life are critical, so the supplier must select materials carefully to ensure optimal performance under the specified operating conditions.

Seallon`s Solutions:

● Given the demanding conditions of high-pressure and high-temperature steam, Seallon recommends using forged F5 alloy steel for the valve body, disc, and stem. Compared to cast components, forged structures offer superior strength, higher material density, and greater resistance to cracking under extreme pressure, making them especially suitable for pipelines operating at pressures up to 160 bar. F5 alloy steel also provides excellent mechanical strength and maintains stable performance at temperatures up to 450°C, making it highly suitable for high-temperature steam applications.

●To further enhance sealing performance and durability, we apply Stellite alloy surfacing on the disc and seat, which offers excellent wear resistance and effectively resists erosion and corrosion from high-temperature steam. As a result, the valve achieves zero leakage and ensures a long service life, even in harsh operating environments.
