FEDP thred Drill Pipe

1. 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). 

2. Drill pipe is designed to allow the introduction of a drilling fluid or air to the bit and to provide the mechanism to transfer energy developed by the drill motor to the bit. 

3. Our Drill Pipe comes in all Grades; Grade "D", "E", "X", "G", "S". Our Tool Joints are manufactured to API Standards. Break-Out Flats and/or Break-Out Lugs are offered in many different configurations, from OEM to custom design.  

4. The correct selection of drill pipe, in most instances, determine how successful you are and what options you have as far as depth, bore hole size, and push and pull down ability.    

5. The selection of drill pipe is one of the most important decisions mainly due to cost and rig capability.   

Below is a breakdown of what the most popular drill pipes are and their benefits.
