The Non-Rotating Float Collar is designed to provide reliable back-pressure prevention during cementing operations. Attached at the end of the casing string, it prevents cement slurry from flowing back into the casing. The collar features an advanced anti-rotation mechanism, enhancing drill-out performance and ensuring a secure and efficient cementing process.
Constructed with high-quality materials, the valve is made of rubber and polymers with excellent tensile strength, ensuring durability under demanding wellbore conditions. The internal components are easily drillable, facilitating seamless operations. Available in single or double valve configurations, the float collar meets diverse application requirements.
The Non-Rotating Float Collar is designed to meet rigorous industry standards, making it a dependable choice for challenging wellbore environments.
The EOT Conventional Float Collar is engineered to ensure reliable performance in cementing operations across vertical, horizontal, and deviated wells. Equipped with a plunger valve as standard, this float collar prevents slurry backflow and allows for maximum circulation rates.
Constructed from seamless casing-grade steel, the float collar can be manufactured in a variety of steel grades, including K-55, L-80, N-80, C-95, T-95, and P-110. Its valve system comprises high-strength polymer materials with natural rubber coating on a phenolic base, ensuring durability and resistance to harsh wellbore conditions. Encased in a high-pressure cement mixture, the valve offers dependable performance while being fully drillable.
The EOT Conventional Float Collar is the ideal solution for consistent and efficient cementing operations, offering robust performance in a wide range of well environments.
