Drill Pipe Premium Tensile Chart
Drill Pipe Premium Tensile, Grades & Mechanical Specification
The Drill Pipe Premium Tensile, Grades and Mechanical Specification Chart is useful for determining the physical dimensions and mechanical properties of the drill pipe. Such physical dimensions include size, length, wall thickness, thread configuration, and diameter. The mechanical property tells about the grade and the strength range for each grade. Knowing the drill pipe specs can help a petroleum engineer or technician properly select a drill pipe, know the standards, and conduct a successful drill.

Drill Pipe Premium Tensile Chart Details
The table shows the following specifications of the drill pipe:
Specification sheet
It details the pipe body specs such as the outer diameter, wall thickness (in), nominal ID, tensile strength (lbs), torsional strength (ft-lbs.), burst capacity (pounds per square inch), and collapse capacity (psi). The sheet also shows the detailed specs of the tubular assembly (the proper design, selection and installation of tubing string), connection, and elevator shoulder.
Outside diameter (OD)
Specified in inches or a fraction of an inch, the OD is the distance between the top to bottom, right to left from the pipe’s outer edges.
Grade
This defines the minimum yield strength and tensile strength which are both measured in pounds per square inch. It also provides the required specs for the properties of the material.
As shown in the table of Tensile and Mechanical Specification of Drill Pipe premium, each grade has its own yield strength. Such grade specification can indicate the suitability of each drill pipe grade. For instance, Grade E is used in medium deep wells from 10, 000 to 15, 000 feet.
The higher the steel grade, the less resistant it is to the corrosion caused by hydrogen sulfide or H2S. On the other hand, the higher the drill pipe strength (anti-extrusion strength, tensile strength, yield strength, and anti-extrusion strength), the higher the steel grade.
Grades S, X and G constitute the high strength drill pipe grades. To calculate the yield strength in pounds, one must know the cross-sectional area via the drill pipe classes. The table of Drill Pipe Premium Grades, Tensile and Mechanical Specification also shows the following grades:
- G-105: Minimum yield strength is 105000 psi
- S-135: Minimum yield strength is 135000 psi
- E-75: Minimum yield strength is 75000 psi
- X-95: Minimum yield strength is 95000 psi
Range
It classifies the length of each drill pipe joint based on the American Petroleum Institute’s specs; the API range constitutes 1 (length in feet: 18-22), 2 (27-30) and 3 (38-45).
Wall
It specifies the wall thickness of drill pipe measured in inches.
Nominal
This refers to the pipe body weight per unit length.
Adjusted
It refers to the weight per foot of pipe that includes the upset (the thickened wall on the tube ends) without the tool joint based on 29.4 ft length.
Tool Joint or TJ
It is a threaded joint of drill pipe; it is differentiated by the pin or the male threaded connection and the female threaded connection known as the box.
Tool Joint Internal Diameter TJ ID (in)
It specifies the internal diameter of the tool joint; the torsional strength ratio establishes the tool joint OD and ID
Tube Outside Diameter TJ OD
It refers to the distance between the inner wall either from right to left or top to bottom.
Tool Joint Yield (ft-lbs)
It is measured in feet and pounds. It describes the torsional strength of the tool joint.
Premium Tube Tensile (lbs)
This describes the strength of premium tubes whenever a tensile stress is applied, up to the point that the tube reaches its structural failure or breaking.
