Raiseboring drill pipes are designed for fatigue resistance with the DI22 thread
Introduction:
Both High Strength and Standard Strength drill rods are designed and manufactured with an emphasis on durability, weight reduction, and serviceability. Our raise boring pipes are designed to be compatible with all of the raise drills operating around the world.
The threaded connections on the rods are cut to exacting standards and verified using precision gauges prior to leaving the factory.
The raise boring drill rods are also designed with features that contribute to long life and serviceability. Each connection is treated in process that coats the threads with protection against galling. Anti-galling protection assists in the retention of thread lubricant and the prevention of metal to metal contact. With proper care and maintenance, the threaded connections are designed to provide years of trouble-free service.
The steel used in the production of raiseboring tools is vitally important because raiseboring tools must be able to withstand tremendous loads.

DI connections
The DI22 series of threaded connections was designed and developed specifically for the raise boring industry. The tapered design of DI22 threaded connections allows for connections to be self-centered prior to engagement. Self-centering reduces the chance of cross threading or other damage during engagement. The coarse thread profile is capable of withstanding the extreme torsional and thrust loads that are applied during reaming. Properly lubricated and torqued, DI22 threaded connections will provide many years of trouble-free operation.
In recent years, the DI315 series of threaded connections was developed to meet the needs of the industry as larger, more powerful drills were designed. The unique thread profile and pitch of the DI315 threaded connections were designed to transmit higher levels of torque and thrust than the DI22 series, without the need for a drastic increase in pipe diameter.
To determine the appropriate drill rod and threaded connection to suit your rig’s capabilities for torque and thrust, consult the chart below.
The rods are also designed with features that contribute to long life and serviceability.
Each connection is treated in a kemplating process that coats the threads with protection against galling.
