New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

True or False: Weld outlets create a branch connection that is weaker than a stub-in connection.

1. True

2. False

3. Not applicable

4. Depends on the application

The correct answer is: False

Weld outlets are designed to provide strong and reliable branch connections. They involve the welding of a fitting onto the main pipe, which creates a strong, durable junction capable of withstanding significant pressure and stresses. This method of connection tends to enhance the overall integrity of the piping system. In contrast, a stub-in connection typically involves inserting a smaller pipe into a larger pipe without the additional support that a weld can provide. While stub-ins can work well in certain applications, they may not achieve the same level of structural strength as weld outlets, particularly in high-stress environments. Therefore, stating that weld outlets create a branch connection that is weaker than a stub-in connection is incorrect, as weld outlets are typically considered to provide superior strength and durability.
