“Piping is the largest threat to plant safety due to the large number of joints that are spread over the entire facility.” This fact means that finding and cutting down on risks and hazards while planning out the piping is important. This practice is known as safety in design and encompasses the selection of proper materials, manufacturing, and efforts to improve the productivity of a plant.
One important element of safety in design are the proper selection of materials to protect against system failures caused by a variety of things. Erosion and corrosion mechanisms that the system will be in contact with should be accounted for. Previous experience with similar operating systems should be referenced. Limitation of the pipe material must be considered as well. For instance, non-metallic piping may be more susceptible to things like ultraviolet light, vibration, temperature, and a variety of other concerns that would be less concerning with metallic piping.
