Slick/Spiral Drill collarFeatures & Benefits: Pressed steel thread protectors are supplied for drill collar; Stress relief groove & bore back Box applied if needed; Hardbanding material ARNCO 100XT,ARNCO 300XT,TCS8000 applied if needed; Slip and elevator recess are machined in accordance with API7-1;
The drill collar is used between the drill pipe and the bit in the drill stem. It is used to put weight on the bit so that the bit can drill. Materials: Drill collars are manufactured from AISI 4145H modified steel, and are supplied in the "as rolled" surface finish condition. Alternative surface finishes are available. Trepanning and Heat Treatment: Drill collars are trepanned and drifted to API Spec 7-1. Full-length heat-treatment processes ensure that mechanical properties meet or exceed API Spec 7-1 requirements. A hardness range of 285-341, Brinell hardness and Charpy "V" notch minimum impact strength of 40 ft-lb at 70 F are guaranteed one inch below the surface. Traceability: Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies. Rigid Inspection Procedures: We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar. Rolling: Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation. Phosphate-coated or Copper Plating: All connections are phosphate-coated or copper plated to improve resistance to corrosion. Slip Groove, Elevator Groove and Size: Huanjie offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines. Thread Protectors: Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.
Non-Magnetic Drill Collars For well drilling NMDC The drill collars are made of modified AISI 4145H chromium molybdenum alloy steel.
