Product Overview

The API Standard Float Collar is an essential downhole cementing tool manufactured by Junchi (SANMON) for oil and gas well construction. This precision-engineered device is installed in the casing string to prevent backflow of cement slurry during primary cementing operations. Constructed from high-strength alloy steel (Grade L80/L80-1/N80) and featuring a high-performance plunger-type check valve with a phenolic resin core, the float collar ensures a secure and reliable seal that withstands extreme downhole conditions including high pressure, elevated temperatures, and corrosive wellbore fluids.

Designed in full compliance with API Spec 10F and API Spec 5CT standards, the float collar provides exceptional drillability with its PDC-bit friendly internal components. The threaded connections are available in BTC, LTC, STC, and premium connections to match any casing program. Every unit undergoes rigorous hydrostatic pressure testing (up to 5,000 psi differential) and dimensional inspection before shipment to guarantee field-ready reliability.

Technical Specifications

Applications

The API Standard Float Collar is widely used in the following oilfield operations:

• Primary Cementing: Prevents cement slurry backflow after displacement, ensuring complete zonal isolation in the annulus between casing and formation.

• Liner Cementing: Ideal for liner hanger systems where reliable back-pressure control is critical during cementing of production and intermediate liners.

• Stage Cementing: Works in conjunction with stage cementing collars for multi-stage cementing of long casing strings in deep wells.

• Horizontal & Deviated Wells: Designed to maintain sealing integrity even in highly deviated and horizontal wellbores.

• HPHT Wells: Suitable for high-pressure, high-temperature wells exceeding 150 deg C and 10,000 psi environments.

Advantages

• API Compliant: Fully manufactured and tested according to API Spec 10F and 5CT standards, ensuring international quality and interchangeability.

• Superior Seal Integrity: Phenolic resin plunger check valve provides exceptional sealing performance and durability under high differential pressure.

• Excellent Drillability: Internal components are formulated for rapid and efficient drill-out using PDC or roller-cone bits, minimizing rig time.

• High-Strength Construction: Alloy steel body with precision-machined threads withstands high torque, tension, and compression loads during installation and operation.

• Corrosion Resistant: Available with optional phosphate coating or nickel plating for enhanced corrosion protection in H2S and CO2 environments.

• 100% Pressure Tested: Every unit undergoes individual hydrostatic testing with certified test reports provided upon request.

• Customizable: Available with various connection types, sizes, and material grades to match specific well requirements.
