Drill Pipe

|

 Product Description -- 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).

  Product Application 

1. Torque Transmission: Drill pipes are designed to transfer drilling torque over long distances, often spanning several miles, from the drilling rig’s surface down to the drill bit.

2. Fluid Circulation: A drill pipe serves as a conduit for drilling fluid, also known as ‘drilling mud’, allowing it to flow down from the surface and back up the wellbore. Drilling fluid is crucial for cooling the drill bit, carrying cuttings to the surface, and maintaining pressure in the well.
