Drill Collar

Features:

  1. Drill collars are manufactured from AISI 4145H modified steel, and are supplied in the "as rolled" surface finish condition. Alternative surface finishes are available.

  2. All connections are phosphate-coated or copper plated to improve resistance to corrosion.  

  3. We 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.

  4. Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.

  5. We also supply spiral drill collars.Spiral drill collars utilize spiral grooves to make mud circulate freely around the drill collar to equalize pressure and prevent a seal from forming.
