New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

The composition of plastic metal pipe results in what key properties?

1. Heavyweight and flexibility

2. Durability and strength

3. Cost-effectiveness and lightness

4. Heat resistance and insulation

The correct answer is: Durability and strength

The composition of plastic metal pipe, often consisting of materials such as polyvinyl chloride (PVC) or polyethylene, provides essential properties that are highly valued in various applications. One of the standout characteristics is durability, as these plastic metal pipes can withstand various environmental factors, including corrosion and chemical exposure, which might degrade traditional metal pipes over time. This durability ensures a longer service life and reduced maintenance needs. Additionally, plastic metal pipes are designed with high strength relative to their weight. This strength allows them to handle significant pressure and mechanical stress without failure, making them suitable for a range of plumbing and industrial applications. The combination of these attributes—durability and strength—enables plastic metal pipes to perform reliably while minimizing the risks of leaks or fractures that can occur in other types of piping materials. In contrast, other options may emphasize characteristics that are less relevant to the properties of plastic metal pipes, such as weight or specific thermal properties. These factors do not accurately capture the critical benefits these pipes offer, making durability and strength the most fitting choice.
