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
MSS SP-69 does not cover:
7. Conclusion
Following MSS SP-69 reduces piping fatigue, leakage risks, and costly rework. It should be used alongside ASME B31.1/B31.3 and MSS SP-58 for a complete support design.
8. References
If you need a specific academic format (IEEE, ASME, or APA), or want to include equations for support spacing or spring selection, let me know and I can extend the draft accordingly. For actual table data or figures, you must purchase or access the standard legally through MSS.
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.
