What type of plates are utilized to shield piping from damage in concealed areas?

Shield plates are specifically designed to protect piping and other mechanical components from physical damage, particularly in concealed or hard-to-reach areas. These plates act as barriers that prevent potential impacts from objects or materials that may be introduced during construction, maintenance, or operational activities. The main purpose of shield plates is to enhance the durability and reliability of piping systems, ensuring they are less vulnerable to accidental damage that could lead to leaks or failures.

While other options like air intake screens, fire-resistant panels, and flame barriers serve important safety and protective functions in specific contexts, they do not fulfill the same purpose as shield plates. Air intake screens are designed primarily to filter and protect air handling systems from debris. Fire-resistant panels are used to contain fire and prevent its spread, while flame barriers focus on stopping the transmission of flames between areas. These alternatives address different concerns and would not be suitable for the specific task of shielding piping in concealed locations from damage.
