API 5DP specifies the delivery specifications for the three product specification levels (PSL1, PLS2 and PLS3) of the steel drill pipe for pipe end thickening and drill pipe butt fusion for oil and gas drilling and production operations in the oil and gas industry.
OCTG Steel Drill Pipe for oil well drilling. Drill pipe is characterized by thin wall, light weight per unit length, mainly to provide mud channel, transmission of tension and torque.
API 5DP drill pipe has many specifications, the common ones are 2 3/8 inches, 2 7/8 inches, 3 1/2 inches, 4 inches, 4 1/2 inches, 5 inches, 5-1/2 inches, etc.
Drill pipe is a steel pipe with a ribbed tail, used to connect the surface equipment of the drilling rig to the drilling and grinding equipment or bottom hole device at the bottom of the drilling well. Common connector types include NC26, NC31, etc. These connectors are also made in accordance with API 5DP specifications. In addition, the steel grades of drill pipes are divided into R780, E75, etc. Different steel grades have different tensile strength and bending strength. The length of drill pipe generally ranges from 6 meters to 12 meters. The specific length can be selected according to the well depth and operation needs.
