Project Description

Holte RC Drill Pipe

Holte Reverse Circulation Drill Pipe

As an early proponent of reverse circulation (RC) drilling Holte has remained dedicated to developing new ways to continually improve RC pipe design and manufacturing techniques.

Holte’s standard reverse circulation dual wall pipe allows for air to move through the annulus between the center tube and outer pipe, while the cuttings flow up freely through the center. Additional jetting pipes can also be added to our dual wall design within the annulus to give added control of air distribution and cutting retrieval for underwater drilling or deep holes.

Simplicity and Durability

Our expertise in understanding materials and the strains placed on them during drilling derives from our years of manufacturing and working in the field alongside the customer. Today, Holte’s design centers on simplicity and durability. Precision machined and heat treated tool joints are assembled under careful supervision using a unique, proven technique that uses heavy wall, durable drill steel formulated and tempered for maximum wear resistance and strength. Our design does not use center tube connectors or complicated inner barrel suspension systems so you never need to worry about costly repairs and downtime in the field. In fact, Holte’s design allows the center tube to be a single, continuous piece of drill steel that it threaded on both ends. Prior to welding the outer pipe to the joints we carefully torque the inner pipe into the machined joint, creating additional strength unmatched by any other drill pipe on the market.

Complete Drilling Systems

Reverse circulation drilling requires all the components to be carefully matched in order to fully realize the benefits of this style of drilling and drill pipe sizing is critical to success. For this reason Holte is proud to offer everything from rig to bit, including custom top head drives specifically designed and outfitted for reverse circulation drilling.
