HT Subsurface Safety Valve
HT subsurface safety valve is a tubing retrievable non-elastomer flapper valve designed for high-temperature thermal production wells. The safety valve was developed using an advanced metal-to-metal seal with enhanced reliability and long life. High-temperature resistant material is used as dynamic piston seal material and 718 or 13cr high-temperature stainless steel is used as body material to ensure overall reliability for working in hostile well environments with temperature rated at 350°C( upper limit of 380°C).
