Drill Pipe
Drill pipe, is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).
DCDMA W-Design Drill Rod – Available from Roschen Group limited with threaded, field-replaceable couplings.
The rods that took the next step from A, N-3 & N-4 Series are still manufactured to the rigid specifications set forth by the DCDMA.
When ordering, match the thread type with your required length.
