– This standard establishes the material, design, fabrication, and inspection criteria to be used in manufacturing standard types of pipe hanger components. It also sets allowable stress values for materials and minimum design load ratings for rigid pipe hanger assemblies.

. While ASME codes provide the "legal" requirements for safety and pressure, they often refer to MSS standards for the specific hardware and spacing details needed to meet those requirements. For example, engineers frequently consult the Pipe Support Spacing Chart
