Question: 1 / 400

How should pipe ends be aligned before fitting?

True to 90 degrees

Aligning pipe ends true to 90 degrees before fitting is crucial because it ensures a proper, square joint, which is essential for both strength and functionality in the finished assembly. This alignment helps achieve uniform gaps and allows for the even distribution of heat during the brazing process, leading to a strong, reliable bond. A 90-degree alignment minimizes the risk of stresses or leaks that could arise from misaligned fittings, ensuring that the assembly can withstand operational pressures and stresses.

In contrast, other alignment angles, such as 45 degrees or irregular arrangements, compromise the integrity of the joint. Curving pipe ends may seem to better accommodate misalignment, but this can also lead to weak joints and difficulty in maintaining consistent brazing conditions. Overall, maintaining a true 90-degree alignment is the best practice for achieving high-quality, durable connections in piping systems.
