Question

Which ONE of the following options is CORRECT in relation to the standard drill pipe?

• A. Nominal weight is equal to the actual weight.
• B. Nominal weight is less than the actual weight.
• C. Nominal weight is greater than the actual weight.
• D. Nominal weight is twice the actual weight.

Hint:

When dealing with standard drill pipes, be aware that the nominal weight is typically lower than the actual weight due to manufacturing differences and material density.

Answer 1

The Correct Option is B

The nominal weight of a drill pipe is the weight specified by the manufacturer and is usually based on a standardized measurement. However, the actual weight of the drill pipe is typically slightly higher than the nominal weight due to manufacturing tolerances and the material's actual density. Therefore, the nominal weight is usually less than the actual weight.
- Option (B) is correct because the nominal weight is generally less than the actual weight of the drill pipe.
- Option (A) is incorrect because the nominal and actual weights are not the same.
- Option (C) and Option (D) are incorrect because the nominal weight is not greater than the actual weight.
Thus, the correct answer is option (B).
