2FZ Double-gate Blowout Preventer

Structural features:Multi-layer gate design: usually has two layers of gates, semi-sealed and fully sealed, such as 2SFZ18-35 double gate blowout preventer, the upper layer is a semi-sealed gate sealant core assembly, and the lower layer is a fully sealed gate sealant core assembly, which can respectively deal with the two situations of oil pipes in the well and empty wells to achieve well sealing and blowout prevention.Main components are made of excellent materials: The main components are forged with alloy steel and heat-treated, with high strength. The surface is plated with nickel-phosphorus, which is corrosion-resistant, oil-resistant, acid-resistant and alkali-resistant, and can extend the service life.Side door and sealing assembly: The side door structure facilitates the installation, maintenance and replacement of the gate. At the same time, the sealing assembly between the components ensures the sealing of the blowout preventer under high-pressure environment, preventing lea…
