This document serves as a comprehensive guide for engineers, designers, and contractors to properly select and apply various types of hangers and supports for piping systems. It ensures that the chosen components can handle the load, temperature, and service conditions of the pipe. Core Purpose of MSS SP-69 The primary objectives of the SP-69 standard are to:

One of the most referenced parts of the standard is the maximum recommended spacing between pipe supports.Proper spacing prevents excessive sagging and controls structural bending stress.The spacing depends on: It ensures that the chosen components can handle

MSS SP 69 covers the dimensions, material, and testing requirements for socket welding stub ends. These fittings are used in piping systems to provide a means of connecting pipes, valves, and other equipment. The standard ensures that stub ends are manufactured and tested to meet specific performance criteria, ensuring reliability and safety in their applications.
