New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

Which type of fitting is known for strength in branch connections?

1. Stub-in

2. Weld outlet

3. Flanged fitting

4. Compression fitting

The correct answer is: Weld outlet

The correct answer is that the weld outlet fitting is recognized for its strength in branch connections. Weld outlet fittings are specifically designed to provide robust and durable connections where a branch pipe is welded to the main pipe. The welding process creates a strong, permanent bond that enhances the overall structural integrity and pressure handling capabilities of the piping system. This makes weld outlet fittings particularly beneficial in applications that require high strength, such as in industrial and commercial settings. Other types of fittings, such as stub-in, flanged, and compression fittings, serve different purposes but may not provide the same level of strength and durability at branch connections. Stub-in fittings are often used for making connections where a stub pipe is inserted into a main line; however, they may not offer the same strength as a welded connection. Flanged fittings are typically used for easy assembly and disassembly and are not inherently as strong at branch connections as weld fittings. Compression fittings, while effective for joining pipes without welding, rely on mechanical force to create a seal and are generally not as strong in high-pressure or critical applications compared to welded connections.
