Our drill pipe is used in most rotary drilling operations (shallow and deep). API drill pipe are fabricated by various API certified manufacturers around the world, principally for use in the drilling of deep wells for the recovery of oil and natural gas. API drill pipe size is denoted by the outside diameter of the pipe body and its associated nominal (pipe body) weight per unit length. The nominal weight per unit length defines the wall thickness and the inside diameter. The lengths of drill pipe elements called pipe body and tool joints, When tool joints (box and pin) are added to a pipe body the average actual weight per unit length of the drill pipe element is increased above the pipe body nominal weight per unit length. API drill pipe is also classified by API material (steel) grade. The API material grade designations and respective standards normally decide minimum yield, maximum yield, and minimum tensile strength of the steel grade. The actual steel used to produce the various API grades for drill pipe fabrication is one of the AISI grade classifications of steel produced in US steel mills. For an AISI grade of steel to be used to fabricate drill pipe of a particular API grade the AISI grade must satisfy the minimum and maximum specification.
