True or False: If proper support is not given to a tube, it may straighten after being joined.

The statement that if proper support is not given to a tube, it may straighten after being joined, is indeed correct. Proper support is essential in ensuring the structural integrity and alignment of piping systems. When pipes or tubes are not adequately supported, they may experience stress and strain, particularly at the joints, leading to potential misalignment or straightening over time.

When joined, pipes can maintain their shape only if the support adequately distributes the weight and compensates for any external forces acting on them. If not properly supported, the weight of the pipe itself or any additional loads can cause it to sag or deform, which would ultimately result in separation or misalignment at the joints. This is a known challenge among pipe fitters and highlights the importance of proper installation techniques and support systems to maintain the intended structure and function of the piping.

Thus, the assertion that improper support can lead to issues with the integrity of the pipe alignment is fundamentally accurate, illustrating the crucial role that support plays in piping installations.
