In the 6th webinar in our ongoing series, we will begin our review of different pipe support elements, concentrating primarily on rigid supports. We'll take a look at a variety of support elements ranging from stock catalog items to completely customized parts. Learn which factors of the piping stress analysis have an impact on the overall design and cost. Also, see how adjustability can be incorporated into the design to accommodate for on-site discrepancies.

  • 5. Introduction Designers Pipe Support Integration Designers Designers Structural PipingEffective coordination between designers of multipledisciplines is necessary during the planning stages. Flow Chart Product of that coordination will be seen during erection and subsequently throughout the plant operation.
  • 6. Introduction Why Pipe Supports ?  Support piping system loads  Restrain or guide our piping system elements  Permit movement of our piping system  Transmit pipe loads to structural members  Prevent heat transfer to the surrounding structure
  • 7. Introduction Key Pipe Support Requirements All pipe supports should be designed to:  Limit piping stresses to acceptable Code standards  Prevent leakage at pipe joints  Limit excessive thrusts and moments on connected equipment  Limit excessive stresses in supporting or restraining elements  Eliminate resonance with imposed or fluid-induced vibrations  Eliminate interference with thermal expansion and contraction in the piping system  Maintain engagement during all phases of operation  Reduce excessive piping sag in piping requiring drainage slope  Minimize excessive distortion or sag of piping subject to creep under conditions of repeated thermal cycling  Limit excessive heat flow, exposing supporting elements to temperature extremes outside their design limits
  • 8. Introduction Other Pipe Support Standards ASME B31.1 Power Piping ASME B31.3 Process Piping MSS SP-58 Pipe Hangers and Supports – MSS SP-69 ANSI/MSS Edition Pipe Hangers and Supports MSS SP-77 Guidelines for Pipe Support Contractual Relationships MSS SP-89 Pipe Hangers and Supports – MSS SP-90 Guidelines on Terminology for Pipe Hangers and Supports
  • 9. Introduction Major factors which impact the overall design and cost of supports include:  Operating Conditions  Loads  Movements  Temperatures  Standard vs. Custom  Material  Dimensions / Sizing  Adjustability  Built-in  As added feature
  • 10. Support Styles & Functions Guidelines to Consider:  Primary support function  Support location  Dependent upon existing steel / foundation  Location of critical equipment (valves, fittings, instrumentation)  Available pipe attachment points (straight-run preferred)  Necessity for supplementary function  Ability to utilize supports during inspections, maintenance and shut-downs  Need for adjustability
  • 11. Rigid Support Applications General Guidelines Load Supporting Limited deflection Attachment PointSpace Requirements Deflection Pipe Load
  • 12. Rigid Support Applications Base Mounted Supports  Guiding  Anchoring  Load Supporting Guide or Anchor Base Mounted ShoeStructural Steel
  • 13. General Support Styles Suspended Supports Auxiliary Steel  Rigid Components  Limited DeflectionStructural Steel Trapeze Style Support High Temperature Yoke Clamp
  • 14. Support Styles & Functions General Rigid Supports – Anchors Characteristics • Restrict movement in all directions • Provide a fixed point against deflection and rotation • Either welded configuration or bolted configuration
  • 15. Support Styles & Functions General Rigid Supports – Guides Characteristics • Confine movement in one or two directions • Used to direct deflection of piping system • Either welded configuration or bolted configuration • Primarily fabricated from structural steel shapes
  • 16. Support Styles & Functions General Rigid Supports – Load Bearing Characteristics • Intended to support pipe load in vertical direction • Accommodates lateral and axial deflections • Max. 4 degrees swing for suspended style • Can be designed for a combinations of loads (operating load, wind load, seismic load, snow load, etc.)
  • 17. Support Design Influences Rigid Supports: Load Required load carrying capacity has a direct impact on the size of support components. 6" Width Required 22,400 lb. Load 80,000 lb. Load 14" Width Required

  • 27. Support Design Influences Rigid Supports: Adjustability Feature Hold-down with Wedge Elevated Pipe Shoe- Supports Clamp Supports
  • 28. Rigid Support Design Guidelines Use standard components as much as possible Build in adjustability to easily accommodate site discrepancies Develop sub assemblies that can be included to produce additional functions
  • 29. Next Webinar Session:August 22, 2012Session 7: Influences on Pipe Support Design – Spring SupportsPart 7 of our continuous Piping Design Series will focus on resilient support elements includingvariable, constant, and big ton springs. We will review the operating conditions that help you to definethe ideal pipe support for your application. See how standard pipe support hardware can be used inconjunction with stock spring components to design entire pipe support assemblies. Discover how tomodify standard spring elements to fit unusual configurations in a piping system.If you have any questions, comments or suggestions, please email usat enews@pipingtech.com
