What must be done to gas piping in contact with corrosive materials?

In the context of gas piping that comes into contact with corrosive materials, it is essential that the piping is protected against corrosion. This protection is crucial because corrosive materials can lead to significant deterioration of the gas piping over time, increasing the risk of leaks or failures that could pose safety hazards.

Corrosion protection methods can include the use of coatings, such as paints or specialized corrosion-resistant materials, as well as insulation that prevents direct contact with harmful substances. The primary goal is to ensure the integrity and reliability of the piping system throughout its operational life. Since corrosion can compromise structural integrity and lead to dangerous situations, adhering to these protective measures aligns with safety best practices outlined in gas codes.

While painting or insulation may help in providing some level of protection, the focus should be on a comprehensive approach to corrosion prevention, making it vital to specifically address the potential for corrosion when evaluating gas piping exposed to harmful conditions. Protecting against corrosion is thus considered the key requirement in this scenario.
