The floating valve features a Super Germet (“SG”) valve that blocks the reverse flow of liquid

Complies with API RP 10F, Category IIIC standards for fatigue strength, pressure, and temperature applicable to equipment with a check valve

Ensures operability in wellbore conditions with any inclination angle

Tolerates 24-hour fluid pumping with calcareous additives

Valve design contains no steel components, allowing for drilling with PDC bits

Can be manufactured with various types of connection threads, including TMK UP premium connections

General Description

SDT Float Equipment namely Float Shoe and Float Collars are used to guide the casing to set in the hole which ensures the quality of cementing. Float equipment from SDT is generally used in the lower section of the well to help decrease strain on the derrick while directing casing past edges and bog zones in the open hole.

The float shoe and float collar manufactured by SDT use the spring driven float valves and are very reliable. The material used for float shoe is drillable with any bit type. Float Collar is run in a casing assembly, usually several joints above the Float Shoe. It serves as an extra back pressure valve sealing against pressures from blow while running the assembly and after the cementing job.

Features & Benefits

All the oil filed sizes available (custom sizes made upon request)

Float collar & shoe is supplied with valve providing sure seal and API RP 10F CATEGORY IIIC qualified

Available in all casing grades with API and Premium threads

Guide shoes drillable material cab be concrete, high-performance polymer or aluminum

Float equipment’s are drillable with any drill bit type

Float collar and plugs are made with anti-rotational design

Designed with maximum industry delta P

Double valve design is available

Cementing stage collars of all sizes available

Protects casing - cementing pressures are confined to the drill pipes in a squeeze job
