Which two types of Nonel tubing are available, and for what purposes are they typically used?

• A. Plain for deep holes; XT for general applications
• B. Plain for adverse conditions; XT for shallow holes
• C. Plain for general applications; XT for deep holes and adverse conditions
• D. Plain for wet conditions; XT for normal conditions

Answer: (C)

The correct answer is based on the specific functionalities of each type of Nonel tubing. The plain tubing is designed for general applications, making it versatile and suitable for a variety of scenarios. Its simplicity allows for reliable performance in standard conditions where there are no extreme environmental factors or specific challenges presented.

On the other hand, XT tubing is specially engineered to handle deep holes and adverse conditions. This type of tubing features additional enhancements to withstand the pressures and challenges encountered in more demanding situations such as increased depths or harsher environmental factors. By being designed for these conditions, XT tubing provides greater safety and effectiveness in environments that require more robust solutions.

This distinction between the two types of tubing is crucial for ensuring that the appropriate materials are used based on the mining context, which is a key responsibility for a shift boss in maintaining operational safety and efficiency.
