Float Collar & Float Shoe – Corrosion Resistant & High-Pressure Resistant

Aluminium Alloy Float Shoe / Collar

• Features: The float requirement valve is made of drillable material, the body is constructed from 6061 aluminium alloy, and the spring is made of tin bronze.
• Standard: Thread machining and inspection comply with API 5B standards; overall performance meets API RP 10F IIIC requirements.
• Scope of application: Suitable not only for standard intermediate casings and production casings, but also for deep wells, ultra-deep wells, and special process wells. The float equipment valve can withstand pressures up to 70 MPa.

Stab-in Float Shoe/Float Collar

• Features: In float collars and float shoes, 'stab-in' specifically refers to an installation method where a stab-in connector is connected to the internal seat of the casing. This design is suitable for efficient cementing of large-diameter casings, offering advantages such as cost savings, simplified operations, and enhanced sealing performance.
• Valve body and spring materials: The float equipment valve is made of drillable materials, with the body constructed from phenolic resin and the spring made of tin bronze.
• Standard: Thread machining and inspection comply with API 5B standards; The overall performance of the float valve meets API RP 10F IIIC requirements.
• Scope of application: Suitable for single-stage cementing of large-diameter surface casings and intermediate casings, and capable of supporting a drill string weight of up to 30 tons.

Double Valve Float Shoe / Float Collar

• Features: The double valve design enhances sealing performance and functionality, making it particularly suitable for complex well conditions and demanding cementing operations.
• Valve body and spring materials: The check valve is made of drillable materials, with the body constructed from phenolic resin and the spring made of tin bronze.
• Standard: Thread machining and inspection comply with API 5B standards; The overall performance of the float valve meets API RP 10F IIIC requirements.
• Scope of application: Suitable not only for standard intermediate casings and production casings, but also for deep wells, ultra-deep wells, and special process wells.

Butt Weld Float Shoe/Float Collar

• Features: The welded end utilizes a 30° butt-weld connection. (The outer diameter of the butt weld casing collar matches that of the casing, and the upper end is beveled only, without any recess, allowing direct welding to the casing.)
• Valve body and spring materials: The check valve is made of drillable materials, with the body constructed from phenolic resin and the spring made of tin bronze.
• Standard: Thread machining and inspection comply with API 5B standards; The overall performance of the float valve meets API RP 10F IIIC requirements.
• Scope of application: Suitable for large-diameter surface casing and shallow intermediate casing ranging from 12-3/4" to 30".

Float Equipment Valve

• Overview: The valve body and piston of the float equipment valve are constructed from high-strength phenolic resin, providing excellent resistance to high temperatures, wear, oil, and corrosion. The piston ball head sealing area is coated with a rubber material that is highly resistant to high temperatures, wear, and oil, and provides strong elasticity and excellent sealing performance. The spring is made of tin bronze, offering superior wear resistance, corrosion resistance, and outstanding mechanical properties. All materials are easily drillable.
• Technical parameters: As the core component of the float collar and float shoe, its overall performance meets the requirements of API RP 10F IIIC. It can withstand a pressure of 35 MPa. It is erosion resistant and can endure temperatures up to 204 °C。 It supports a flow rate of up to 2000 L/min, and has a service life of up to 24 hours.
