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 customersâ?? 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.

Product details of API Spec 7-1 standards Drilling Rig Square Kelly and Hexagonal Kelly for Sale Kelly is the drive part of whole drill string, it transmit the torsional energy from the rotary table to the in the bottom of the hole. The precision-machined kelly is a heavy square or hexagonal steel bar supported by the swivel through the rotary table and connected to the first joint of drill pipe in the drill string. Our kelly has been approved by the NS-1 certification. Straightness is the key manufacturing process. Straightness is checked before, during and after each machning operation. Flats are precision-milled to API and NS-1 specifications. All milling is performed on specially designed rigid kelly mills.Each kelly is furnished with a pressed steel thread protectors. Features of Kelly They are made of AISI 4142H-4145H forged or rolled alloy structural steel. Quenching plus tempering thermal treatment will be conducted over the whole length. Its Brinell hardness can reach 285-341 on the basis of such thermal treatment. Charpy impact energy: 54J. The formulated process can ensure that the misalignment of the hole reaches the standard wall thickness. When ordering the Kelly please specify: 1. kelly type(square or hexagonal) 2. nominal size and overall length 3. upper and lower connection
