Drill Collars Dealers

Drill Collars (Slick and Spiral) are processed from AISI 4145 H Chromium Molybdenum Alloy Steel and are fully heat treated to a Brinell Hardness range of 285-341 BHN and have a minimum Charpy V-notch Impact strength of 40 ft-lbs. at 70° F and a minimum elongation of 13%. The mechanical properties meet or exceed API 7-1 requirements. The physical properties are guaranteed one inch below the surface at ambient room temperature. Mechanical Properties (4145 H Chromium Molybdenum Alloy Steel) Drill Collar OD (in.)Minimum Yield Strength (psi)Minimum Tensile Strength (psi)Minimum Hardness(BHN) 3 1/8 to 6 7/8 110,000 140,000 285 7 to 11 100,000 135,000 285 Drill Collars are precision trepanned to close bore tolerance and all bores are drifted to API 7-1. The connections are cut on CNC Machines. All API connections comply with dimensional requirements specified in API 7-1 and guidelines presented in API RP 7G. Spiral Drill Collars:To avoid differential pressure sticking in the hole, the surface of drill collars can be provided with three spiral grooves reducing the contact area with the wall of the hole. The spiral grooves let mud circulate freely around the Drill Collar to equalize pressure and prevent a seal from forming. Loss of weight is approximately 4%, compared to Slick Drill Collars. API Stress Relief Features and API Bore Back Box decrease the frequency of fatigue failures by improving the bending strength of pin and box connections, thereby, reducing high stress concentrations. Stress relief features are machined in compliance with API 7-1. Connections NC23, NC 26 (2 3/8 IF) and NC 31 (2 7/8 IF) do not have sufficient metal to accommodate stress relief features. Slip and Elevator recesses improve handling efficiency and safety. The upper radius of the elevator recess is cold-rolled. Slip and Elevator recesses can be used together or separately. Slip and Elevator Recesses are machined in compliance with API RP 7G guidelines. On enquiries and orders, please specify:Outside Diameter, Bore, Length, Connection Size and Type, API Stress Relief Features on Pin and Box ends, Slick or Spiral, Hard banding (band location and width), Slip or Elevator Recesses, Pressed or Cast Steel Thread Protectors, and any special features. Quality Control:Drill Collars are inspected to comply with API standards. The inspections include visual dimensional checks as well as Ultrasonic Inspection on each bar over its full length and section. Thread Profile, Lead, Taper, Pitch and Gage Standoff are 100% inspected on each Drill Collar to all applicable API Specifications and recorded.

Drill Collar Slip are having multi segment design to give a full wrap around the diameter of Drill Collars having an API Taper of 4 inch per feet on the diameter fitted with Circular Buttons and up right handles, have extra back support to ensure sufficient strength & support to the inserts of various sizes. It is general practice to use Safety Clamps while handling Drill Collars so the top surface of these slips are designed flat to ensure smooth fitting of the safety clamp.

The wiper is made from 2 symmetrical halves which both have a flexible wiper insert that can accommodate different size drill pipes and drill collars. The operator simply wraps the tool around the drill pipe or drill collar and locks it into place using the magnetic locks at the opening. Should the stress on the tool exceed the calibrated safe operating stress, the magnetic lock will open up to ensure safety of the operator and those nearby.

• Brand Name: Molygraph
• Model Number: THREAD COMPOUND EF

Benefits: 1. contains copper flakes, non-metallic and environment friendly blend of natural, inorganic ep & aw additives that provide superior lubrication 2. excessive circumferential is prevented by increasing the co-efficient of friction under compressive forces. 3. ep additives provide protection against galling and seizing and help in easy breakout 4. contains no lead and zinc 5. protects against rust & corrosion 6. aluminum complex thickener provides brushability and stability over a wide temperature range. 7. excellent frictional characteristics help to tighten the connections at desired stress levels. 8. service rating: (-) 18°c [0°f] to (+) 230°c [446°f]. Applications: 1. for lubrication of jack up rig leg racks and pinions. 2. for lubrication of drill pipes, collars, tools and jacking system. 3. for horizontal drilling machines.
