    What is 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).

     

    How to Work with Drilling Pipe

    The drilling tool is connected drill rod for transferring power. The drill string is usually part are: drill, drill collars, drilling pipe, stabilizers, special connectors and Kelly. The basic role of the drill string are: (1)control the drill bit; (2) imposed WOB; (3) transmission of power; (4) transporting drilling fluid; (5) special operations: extrusion of cement, handling underground accidents.

     

    Drilling pipe is trailing with screw thread for connecting the drilling rig located at the bottom of surface drilling equipment and mill equipment or bottom outlet device. The purpose is to drill the drilling mud delivered to the drill bit, and drill with the increase, decrease or rotating bottom outlet means. Drill pipes must be able to withstand great external pressure, twisting, bending and vibration. In the mining and oil and gas refining process, the drill pipe can be used multiple times.

    API 5DP specification is under the jurisdiction of the API Committee on Standardization ofTubular Goods. The purpose of this specification is to provide standards for drill pipe suitable for use in drilling and producing operations. 

    SPECIAL PROCESSES of API 5DP Specification for Drill Pipe Special Processes are the final operations which are performed during pipe manufacturing that affect attribute compliance required in this document (except chemistry and dimensions). The applicable special processes are heat treatment, nondestructive testing, and, if applicable, cold finishing
