What is API 5D pipe?
API 5D pipe is a drill pipe that meets the standards of the American Petroleum Institute (API). API 5D drill pipe is mainly used for oil and gas drilling operations and is an important part of drilling equipment.
API 5D drill pipe specifications：
OD | ID | Wall Thickness | Weight | Steel Grade | Yield Strength | Tensile Strength | Thread Type |
2-3/8" | 1.25" | 0.50" | 6.65 | E-75 | 75 | 100 | NC26 |
3-1/2" | 2.50" | 0.50" | 13.3 | X-95 | 95 | 110 | NC38 |
4-1/2" | 3.25" | 0.625" | 19.5 | G-105 | 105 | 125 | NC50 |
5" | 3.875" | 0.562" | 21.9 | S-135 | 135 | 150 | NC50 |
6-5/8" | 5.50" | 0.562" | 27.7 | S-135 | 135 | 150 | NC56 |
1.Material requirements: API 5D drill pipe is usually made of high-strength alloy steel, which is heat-treated to improve its strength and toughness to ensure durability under extreme conditions.
2. Dimension tolerance: The standard specifies in detail the allowable deviations of key dimensions such as the outer diameter, wall thickness, and length of the drill pipe to ensure the accuracy of each part and avoid mismatched joints or unstable structures during use.
