Float Valve Sub is an important tool in petroleum exploration and drilling engineering. The float valve sub is connected at upper part of drill bit, the float valve assembly in sub is near the bit connecting thread and the float valve sub also can be necessary position of drill string. The main application is,when connect with single piece pipe, to prevent mud coming in, mud up returning and blocking hole. When blowout takes place,blowout in drill string will be avoided because nozzle is closed automatically by valve cap for float valve assembly .
When ordering please specify:

A. Slick Drill Collar
Note: Drill collar is mainly used to provide bit weight to drill bit so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. The Drill collar are manufactured strictly from API Spec7-1 and SY5411 standard.
B. Spiral Drill Collar
Note: Spiral drill collar is used to reduce contact area with hole so as to avoid efficiently bit sticking from diffirential pressure. The drill collars are manufactired strictly according to API Spec7-1 and Standard SY5144
C. Spiral Drill Collar With Elevator Groove And Slip Groove
Note: Elevator groove and slip groove made on box thread face of slick drill collar or spiral drill collar can be used as lifting sub and safety slip when trip out. The technical parameters for elevator groove and slip groove is as per API SPEC7-1. Hardbanding is optional at customers' requests.
D. Non-magnetic Drill Collar
The as cold rooled finish on both ID and OD surface with unique technical process strengthen the structure and ensures the tools with optimal resistance to stress,corrosion,cracking and the mechanical performance is greatly enganced.
