– Municipal and industrial project specifications continue to reference MSS SP‑69 directly. For example, one typical specification states: “Metal Pipe‑Hanger Installation: Comply with MSS SP‑69 and MSS SP‑89. Install hangers, supports, clamps, and attachments as required to properly support piping from the building structure”.
A sheet metal jacket that wraps around the outside of the insulation to distribute the load at the hanger point. Critical Engineering Considerations in MSS SP-69
: Ensure that the material of the stub end is compatible with the piping system it will be used in. Refer to MSS SP 69 for specified materials.
A: No. MSS SP‑58‑2009 incorporates all of the content of MSS SP‑69‑2003. However, if your project specifications or contracts specifically call out MSS SP‑69 by name, you may still need to reference it for compliance purposes.
and ASME B31.3 (Process Piping) mandate that piping systems must be properly supported to limit stresses within allowable boundaries. mss sp 69 pdf
What specific (steel, copper, PVC) are you currently designing for?
: Establishes standard rules for handling piping displacement due to dynamic loads, system vibrations, and intense thermal expansion.
The standard covers a massive range of materials beyond just steel, including plastic, glass, cast iron, and fiberglass reinforced pipe (FRP) .
MSS SP-69 is a copyrighted document, and it is crucial to use the official, updated version to ensure engineering compliance. You can purchase the . A sheet metal jacket that wraps around the
The scope of MSS SP 69 covers steel lug and wafer butterfly valves with a nominal diameter of 2 inches to 24 inches (50 mm to 600 mm). The standard applies to valves with a variety of end connections, including wafer, lug, and flanged types. The valves covered by this standard are typically used in a wide range of applications, including water treatment, chemical processing, and oil and gas production.

For engineers and specifiers selecting support systems for new projects, acquiring the current edition of MSS SP‑58 is strongly recommended, as it provides the most up‑to‑date guidance in a single consolidated volume. For those maintaining legacy systems, responding to older specifications, or conducting historical research, the original MSS SP‑69 PDF remains a legitimate and valuable resource—provided it is obtained through authorised channels.
The PDF standard outlines several critical factors for successful pipe support design. 1. Types of Pipe Hangers and Supports
