What installation considerations should be made for piping and hoses?

The correct choice highlights the importance of addressing the physical dynamics that affect piping and hoses during installation. Provisions for expansion, contraction, jarring vibration, and settling are critical because these factors can significantly impact the integrity and safety of the installation over time.

Materials, such as piping and hoses, naturally expand and contract with temperature changes. If these movements are not accommodated, it can lead to stress points that may cause leaks or damage. Additionally, jarring vibrations from the surrounding equipment or environment can lead to wear and tear or even failure of the connections, resulting in hazardous situations, especially in systems handling compressed natural gas.

Settling of the support structures can also affect the alignment and support of piping systems. If the installations do not provide for potential settling, it could lead to misalignment or stress that may result in leaks or ruptures in the hose or piping.

In contrast, being tightly secured can be beneficial; however, it must be done while allowing for the necessary movement. Installing at any angle without considering these factors might not provide a safe or functional system. Similarly, rigid installations without considering flexibility could lead to failures on a significantly higher scale, where the system's reliability is compromised.
