What requirements does B31.6 cover?

The focus of B31.6 is on the construction and inspection of process piping systems. This standard outlines the necessary guidelines and practices that should be followed to ensure safety, performance, and reliability of piping used in various processes, particularly in the chemical, petroleum, and similar industries. It includes specifications for materials, design, fabrication, inspection, and testing, ensuring that the piping systems can handle the pressures and conditions specific to industrial applications.

In contrast, the other options pertain to different aspects of piping systems or materials. For example, piping for pulp and paper is covered under different codes that specifically address the unique characteristics of that industry. Similarly, the construction of plastic piping systems is guided by standards more focused on the properties and applications of plastic materials rather than process piping. Lastly, while new piping technologies might evolve and be regulated, B31.6 specifically deals with established process piping practices rather than emerging technologies.
