What must piping and hose installations account for?

Piping and hose installations in CNG delivery systems must account for several critical factors to ensure safety and reliability. The correct answer emphasizes the need to consider vibration, jarring, settling, and expansion.

Vibration and jarring can result from the operation of the vehicle and the movement of the CNG itself, which may lead to wear and stress on pipes and hoses over time. If these factors are not properly accounted for in the installation design, there is a potential risk of leaks or failures, which could lead to hazardous situations.

Settling is another important factor, as pipelines may shift position or settle into place over time, particularly if installed in a manner that doesn’t accommodate ground movement or other changes. This factor is crucial in ensuring that the installations maintain their integrity throughout their operational life.

Expansion and contraction due to temperature variations also affect piping materials, particularly those that are rigid. Gas temperatures can fluctuate significantly, and if the system is not designed to accommodate these changes, it could result in undue stress on the connections or even ruptures.

Options focusing only on expansion and contraction, weight limitations, or environmental impact overlook the necessity of a comprehensive approach that addresses multiple forces acting on the installations. A full understanding of all the dynamics involved ensures that C
