Visual Testing (VT) Practice Exam

A hanger assembly attached to a pipe with a pipe clamp is considered what type of attachment?

1. Class 1 component support

2. Integral attachment

3. Restraint assembly

4. Non-integral attachment

The correct answer is: Non-integral attachment

In the context of structural design and visual testing, a hanger assembly attached to a pipe with a pipe clamp is classified as a non-integral attachment. This is due to the way the hanger assembly interacts with the pipe: it provides support but does not become a permanent part of the piping system. Non-integral attachments are designed to hold or support components without being physically integrated into their structure, allowing for flexibility and ease of maintenance. A non-integral attachment can be removed without causing damage to the component being supported. This characteristic is important in both construction and maintenance environments, as it facilitates easier repairs or modifications. By contrast, integral attachments typically involve a more permanent connection and are often treated as part of the system they support. Understanding this distinction is vital for assessing the integrity and configuration of support systems in various engineering applications.
