True or False: Two things that must be considered when tacking two pipe sections together are maintaining a gap and keeping the two pipes straight.

The assertion is true because when tacking two pipe sections together, maintaining a gap is essential to ensure proper alignment and facilitate the subsequent welding process. A small gap allows for heat distribution during welding and helps prevent issues like warping or distortion caused by the intense heat.

Additionally, keeping the two pipes straight is crucial for alignment. Misalignment can lead to mechanical stresses on the joints, which might compromise the integrity of the piping system once it is fully assembled. Proper alignment ensures that the flow through the pipes is not obstructed, which is vital in ensuring efficiency in fluid transport and minimizing pressure drops.

Thus, both maintaining a gap and ensuring the pipes are straight are fundamental practices in pipe fitting to ensure that the joint is structurally sound and functionally effective.
