Flanged forged steel globe valve SGL41-F were used for a steam pipeline of power plant in Ekaterinburg, Russia

Project Requirements:

The customer requires a flanged globe valve suitable for a steam pipeline operating at 180°C. The valve must withstand prolonged exposure to high temperatures while offering superior corrosion resistance. Zero leakage and long service life should be considered, so the supplier is responsible for selecting appropriate materials to ensure optimal performance based on the working medium and temperature conditions.

Seallon`s Solutions:

● Seallon recommends a A105 body, which has high strength and thermal resistance and performs well in high-temperature steam environments.

● The valve disc and stem are made of SS316L, which provides excellent corrosion resistance and high-temperature stability. This ensures long-term reliability in demanding operational conditions.

● We also apply Stellite surfacing welding on the disc and seat, which can effectively improves wear resistance and corrosion resistance. It can ensure valve’s sealing and durability to reach zero leakage and long service life.
