Product Description 1. Non-magnetic Drill Collar 2. Standard: API Spec. & NS-1 Spec 1. Non-magnetic Drill Collar 2. Standard: API Spec. & NS-1 Spec 1. Non-magneticdrill collar is used to reduce contact area with hole so as to avoid efficiently bit sticking from Vigor drilling could supply the Drill collar according to the API Spec7-1, NS-1 standard. Description: 1. Material: 4145H/4145Hmod or Non-magnetic. 2. Standard: API7-1, NS-1. Norsok 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.
