MSD rotary drill pipes are listed by O.D., wall thickness, tube weight, recommended connection, and suggested bit size range to support drill-string selection and technical confirmation.
MSD rotary drill pipes are available with O.D. options from 4" to 13 3/8" (101.6 to 340 mm). The current table compares wall thickness, tube weight, recommended API REG, API IF, or BECO connections, and suggested bit size ranges from 4 5/8" through 17 1/2" for technical confirmation of the required configuration.

Read MoreRotary drill pipes, also described as rotary drilling pipes or rotary drill rods for relevant requirements, are selected as part of a rotary drill string. This page covers pipe configurations listed by O.D., wall thickness, tube weight, recommended connection, and suggested bit size range.
Rotary drill pipes should not be selected as DTH drill pipes. Bit subs, adapters, stabilizers, and rotary bits are separate drill-string components with their own specifications. Their details may still be required when confirming how a rotary drill pipe will connect within an existing or new assembly.
Begin with the required pipe O.D. and compare the wall-thickness and tube-weight options shown for that size. The current specifications cover O.D. options from 4" to 13 3/8" and present both metric and imperial values, allowing the required configuration to be checked without relying on a nominal product name alone.
Each listed configuration also includes a recommended connection and a suggested bit size range. These fields should be reviewed together with the required hole or bit size and the existing rotary drilling system. A suggested range in the table supports selection review but does not by itself confirm compatibility with every drill string or rig.
The current rotary drill pipe specifications include API REG, API IF, and BECO connection options depending on the listed pipe configuration. The selected connection must correspond to the mating component in the drill string. The same pipe O.D. does not confirm that two pipes have the same connection or can be interchanged.
Before ordering, check the pipe connection against the rotary head or rig-side connection and the adjoining bit sub or adapter. The tricone bit, stabilizer, and other components should be considered only as parts of the same matching review. If a change in connection is required, the relevant sub or adapter arrangement should be confirmed separately rather than assumed from pipe size.
For mining and rotary blasthole requirements, or for an explicitly specified rotary water-well requirement, the application name alone does not determine the pipe configuration. Confirm the pipe O.D., wall thickness, tube weight, recommended connection, suggested bit size range, rig information, and complete rotary drill-string arrangement.
For replacement rotary drill pipes, provide the existing pipe markings, measured O.D., wall thickness, connection details, photographs, and drawings where available. This information helps distinguish the required rotary pipe or rod from products that may have a similar nominal size but a different connection or system purpose.
For technical confirmation and quotation, provide the required pipe O.D., wall thickness, connection, suggested or current bit size, rig model or rotary-head connection, mating drill-string component information, drilling application, and quantity. For a replacement request, also send the current pipe markings, dimensions, photographs, drawings, or a sample reference where available.
MSD can review the supplied information against the configurations published on this page and identify any connection or drill-string details that require separate confirmation before an order is finalized.
