Pipe Hangers and Supports – Selection and Application (ANSI-approved American National Standard)

This Standard Practice was developed by a cooperative effort of representatives of the pipe hanger manufacturers. It is based on the best practice current at this time and on the collective experience of the industry. There are three companion standards – MSS SP-58 and MSS SP-89 relate to hanger materials, design, manufacture, fabrication and installation; MSS SP-127 relates to the design, selection, and application of bracing for piping systems subject to seismic – wind – dynamic loading. In addition, the MSS Technical Committee 403 has developed guidelines for pipe supports contractual relationship and on hanger terminology as covered in MSS SP-77 and MSS SP-90 respectively.
This Standard Practice presents the recommended practice for the selection and application of pipe hangers and supports for all service temperatures.
This Standard Practice has been withdrawn as an active American National Standard effective 6/06/2014. The contents of this Standard Practice is now part of ANSI/MSS SP-58-2009, which can officially be utilized and referenced in place of SP-69. The withdrawn standard will remain available from MSS as a historical document.
