Basic floating Equipment includes the Float Collar and Float Shoe: The Float Shoe contains a backpressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing. Float Collars are placed one to three joints above the Guide Shoe or Float Shoe. They provide a seat for the cement plugs, the bottom plug pumped ahead of the cement and the top plug behind the full volume of slurry. Once seated, the top plug shuts off fluid flow and prevents over-displacement of the cement. The space between the Float Shoe and the Float Collar provides a containment area to entrap the likely-contaminated fluids from the wiping action of the top cementing plug, securing the contaminated fluid away from the shoe where a strong cement bond is of primary importance. Float Collars include a backpressure valve and serve basically the same function as the Float Shoe.

API standard drill pipe Float valve is one of necessary tool for drilling, it consists of float valve sub and float valve, the main function are to prevent drill cuttings come into mud when connecting each joint and the bit bore block caused by back flow of silt. Engineered with precision and designed to regulate fluid flow, our high-quality float valves ensure optimal performance and dependable sealing. Crafted from durable materials, these valves offer superior resistance to corrosion, abrasion, and harsh operating conditions. With their innovative design and advanced functionality, float valves play a vital role in preventing backflow, maintaining pressure control, and enhancing safety in oilfield operations. Trust in our float valve solutions to optimize fluid control, increase efficiency, and achieve smooth-running operations in your oilfield projects. 1.1 Plunger-type float valves: The Model F is a plunger-type float valve that provides a positive instantaneous shut off, providing constant fluid control while drilling. The Model F is a reliable and economical selection under standard drilling operations. 1.2 Flapper-type float valves: The Model G is a flapper-type float valve that, when opened, offers an unobstructed bore through the float valve. The uniquely designed flapper closes rapidly to prevent shavings from entering the drill string when circulation stops and also assists primary BOP equipment in maintaining internal pressure control. The valve will fully open when the first joint is raised from the hole, preventing pulling wet joints.
