Project Description

Dual Wall Threaded Drill Pipe

  • Dual wall—air travels through the annulus & tool joints

  • Cuttings exhaust through the center

  • Steel formulated, heat-treated, torqued, and welded for maximum strength

Holte Reverse Circulation Drill Pipe is a one piece, dual tube joint with no center tube connectors or o-rings to replace. We have designed and built many custom variations.  All our pipe is made of heavy wall, durable drill steel and formulated and tempered for maximum wear resistance and strength.

Prior to assembly, each joint (Pin and Box) are machined from high strength steel alloy rich in nickel, chrome and molybdenum. They are then heat treated in house in a high carbon atmosphere to approximately 1,700 degrees to develop a file hard surface and tough core. The pins and boxes are then assembled in a unique, proven manner that ensures the ultimate in strength and durability.
