Final answer:
The maximum allowed distance between piping supports for NPS 2 piping run horizontally is typically 10 feet.
Step-by-step explanation:
In engineering, the maximum allowed distance between piping supports for NPS 2 piping run horizontally typically follows industry standards. According to the American Society of Mechanical Engineers (ASME) B31.1 Power Piping Code, the maximum spacing for NPS 2 piping run horizontally is 10 feet (or 3.05 meters). This specification is essential for ensuring structural integrity, minimizing sag, and preventing undue stress on the piping system, thus contributing to the overall safety and reliability of the engineering infrastructure. Complying with such standards is fundamental in the design and installation phases to guarantee the longevity and efficiency of piping systems within various engineering applications.
