To ensure you are using the most accurate, legal, and updated guidelines, the standard should be purchased directly via authorized distributors such as the official website, ANSI , or IHS Markit .
– Companies such as Piping Technology & Products (PT&P) follow the basic designs set forth by MSS SP‑69 for the selection and application of pipe hangers and supports. For many manufacturers, SP‑69 remains the primary reference for ensuring that the supports they supply are appropriate for the intended service conditions.
A crucial element often extracted from MSS SP-69 technical documentation is the maximum recommended spacing between pipe supports. Proper spacing prevents excessive sagging (deflection) and controls bending stresses. mss sp 69 pdf
The core objective of the standard is to ensure that piping weights are safely distributed to the building structure or foundations without introducing detrimental stresses into the piping material, joints, or connected equipment (such as pumps and turbines). Key Core Objectives of the Standard

The is more than a file—it is a decision-making tool that prevents pipe failures, reduces maintenance costs, and ensures code compliance. Whether you are designing a cryogenic LNG line or retrofitting a 1950s boiler house, this standard provides the visual grammar needed to specify and install supports correctly.
Platforms such as S&P Global (formerly IHS Markit), Techstreet, ANSI, and ASTM operate licensed storefronts where you can legally purchase individual licenses or multi-user corporate subscriptions. A crucial element often extracted from MSS SP-69
Main steam lines in power generation, high-temperature refinery piping. 4. Anchors, Guides, and Restraints
– As described above, this standard tells the user how to select the right type of support and how far apart to place them.
