Product Description
1）A Float Shoe is a critical downhole tool installed at the bottom of a casing string during oil and gas well construction. It guides the casing into the wellbore while preventing backflow of drilling fluids or cement slurry via a built-in check valve mechanism. Designed to meet API 5CT/5B/10D, ISO 10427 standards, float shoes ensure efficient cementing operations, enhance wellbore integrity, and reduce risks of casing collapse or fluid migration.

Comment & FAQ
1. How does a float shoe differ from a float collar?
A: A float shoe is installed at the casing bottom, while a float collar is placed higher up. Both include check valves, but the shoe has a guiding nose.
2. Can float shoes be reused?
A: No – they are typically single-use due to cement hardening and valve damage post-operation.
3. What materials are best for sour gas wells?
A: Duplex steel or CRAs with NACE MR0175 certification to resist H₂S corrosion.
4. How to verify valve functionality before installation?
A: Perform pressure testing (e.g., 1.5x working pressure) and inspect for leaks.
5. Are custom sizes available for non-API casing?
A: Yes – manufacturers can tailor OD, ID, and valve configurations to project needs.

Key Features Durable Construction
Made from high-strength alloy steel, composite materials, or corrosion-resistant alloys (CRAs) for harsh environments.
Cementing Ports
Strategically placed ports enable uniform cement displacement behind the casing.
Guide Nose
Streamlined shape reduces drag and facilitates smooth casing run-in, especially in deviated or horizontal wells.
API Compliance
Manufactured to API 5CT/5B specifications for dimensional accuracy and pressure integrity.
