What must be done to protect underground and aboveground piping?

Protecting piping, both underground and aboveground, from corrosion is essential for ensuring the integrity and longevity of the systems that transport compressed natural gas (CNG). Corrosion can weaken the material, leading to leaks, failures, and potentially hazardous situations. This is particularly critical for CNG systems, where the risk of leaks can pose significant safety and environmental threats.

Corrosion protection can come in the form of various methods, including the application of protective coatings, cathodic protection systems, and regular inspections. These strategies help extend the lifespan of the pipes and maintain safe operations.

While painting and insulation may provide some degree of protection, they primarily serve different purposes. Painting can help prevent corrosion but is not the sole method of corrosion protection. Insulation, on the other hand, is used to manage temperature and reduce energy losses rather than directly addressing corrosion issues. The idea that piping does not require protection is misleading, as all piping systems are susceptible to environmental factors that can lead to corrosion.

Overall, focusing on corrosion protection is a fundamental aspect of maintaining both underground and aboveground piping systems in CNG operations.
