Non-magnetic Cable Check Valve
Product Description:
The non-magnetic cable check valve is a complementary device used in directional drilling processes. It serves multiple functions including signal transmission, delivering power media to bottom hole motors, preventing gas outbursts and backflow of power media, and transferring torque from the drill rig. This valve is primarily designed for use with long-range (up to 1000 meters) directional drilling rigs.
Product Features:
Integrated Structure: The joint and rod body are integrally formed and undergo comprehensive tempering treatment to enhance durability.
High Tensile and Torsional Strength: With a tensile strength ≥1035 MPa and yield strength ≥965 MPa.
Excellent Toughness: Offers toughness comparable to 135-grade steel.
Good Sealing Performance: Ensures stable signal transmission under pressures up to 10 MPa.
Applications:
The non-magnetic cable check valve is mainly used in conjunction with center-through cable drill pipes to ensure reliable operation in complex drilling environments.
