The non-magnetic drill collar is made of self-developed low-carbon stainless steel,which implements API specifications and SY/T5144 standards,and can be cold rolled on the threads,and can process double shoulder threads and other special threads.

 

Description:

1. Material: 4145H/4145Hmod or Non-magnetic.

2. Standard: API7-1, NS-1.

 

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.
