Rotary Drill Rods
North Star Rotary Drill Pipe is manufactured using the highest quality 4145 HT & Quenched alloy tool joints with options of HT & Quenched alloy or hot-rolled seamless carbon tube.
Mid-Body Tube options include:
4140 Alloy: This alloy tube is applied in hard abrasive formations as a solution to slow the mid-body wear that is common in these types of geological formations. The physical characteristics, yield, tensile and HRC hardness of this alloy tube deliver a more durable, wear-resistant mid-body tube than that of standard, hot-rolled, seamless carbon tube.
ST52: This mid-body tube is typically applied in less abrasive formations. This is a hot-rolled, seamless carbon tube.
