Drill Pipe

DRILLMAX® drill pipes accommodate different applications performed by water well drillers across the country. Designed as part of the whole system — drill rig and tooling — there are primary drill pipe sizes and drill pipe weights for each specific DRILLMAX® water well rig. However, the drill pipes are engineered to be able to be used on any rig in the DRILLMAX® line.

Higher-grade material for the mid-body strengthens drill pipes for increased durability. Engineers also added a stress-relief groove where pin end meets body of drill pipes for additional durabilty. The radius spreads the load on the drill pipes to increase fatigue life of pipe. Higher hardness tool joints also facilitate longer wear life.

Several drill pipes are lighter weight than legacy versions for less weight and wear on the rig.
