Title:
Application of MSS SP-69 in Pipe Support Selection and Installation
Abstract
This paper discusses the guidelines of MSS SP-69 – “Pipe Hangers and Supports – Selection and Application.” It outlines the standard’s classification of support types, selection criteria based on piping material and service conditions, and best practices for safe load distribution. The paper aims to assist engineers in complying with MSS SP-69 to prevent pipe sagging, stress concentration, and vibration damage.
1. Introduction
Proper pipe support is critical for the integrity of industrial and commercial piping systems. MSS SP-69 provides a standardized methodology for selecting and applying pipe hangers and supports. It complements MSS SP-58 (materials and manufacturing) and MSS SP-127 (mechanical properties).
2. Scope of MSS SP-69
MSS SP-69 covers:
3. Support Types and Identification
The standard assigns figure numbers to common support configurations (e.g., Figure 1 – Adjustable clevis hanger, Figure 10 – Roller support, Figure 24 – Sway brace). Each figure includes:
4. Selection Criteria
Engineers should consider:
5. Application Guidelines
6. Limitations

The MSS SP-69 standard, titled "Pipe Hangers and Supports – Selection and Application," is a critical industry guideline for the engineering and installation of piping systems. While historically significant, modern practitioners should note that it has been officially withdrawn as an active standard. Its technical content was fully integrated into the more comprehensive ANSI/MSS SP-58 standard starting with the 2009 edition. Core Purpose and Scope
Originally approved in 1966, the MSS SP-69 PDF served as the primary manual for the proper selection of pipe supports across all service temperatures. Its main objectives were to:
Guide Engineering Design: Assist engineers in writing job specifications for hanging and controlling the movement of piping.
Inform Erectors: Provide installation teams with details on which components (like clamps, hangers, or guides) were suitable for specific loads and environments.
Standardize Practices: Establish a "common practice" for manufacturers, users, and the general public to ensure system safety and reliability. Key Technical Sections
The standard was organized into several critical sections that detailed how to manage mechanical stress and thermal expansion in piping: ANSI/MSS SP-69-2003 - Pipe Hangers and Supports
The MSS SP-69 standard is an essential "how-to" guide for the industry, specifically focusing on the selection and application of pipe hangers and supports. While many of its core contents have been integrated into the broader MSS SP-58 standard since 2009, it remains a fundamental reference for ensuring piping systems are supported correctly under various thermal and load conditions.
