TECHNICAL SCOPE OVERVIEW

Engineered for Structural Durability and Constructability

Pipe racks are the critical arteries of refineries, chemical plants, and offshore topsides, carrying high-pressure process pipelines, electrical cable trays, and utility systems. ODS specializes in pipe rack engineering that accounts for severe thermal pipe friction, anchor thrust forces, wind shielding, and longitudinal longitudinal seismic effects.

Detailed Engineering Capabilities

Multi-tier continuous and modular pipe rack structural design
Thermal anchor and friction force interaction modeling
Piping expansion loop supports and directional guides
Cable tray, instrument bridge, and battery limit gantry design
Modularization of pipe rack segments for transport and fast-track site erection
Fireproofing zone determination and load combination mapping

Typical Deliverables Issued

  • Pipe Rack Framing Layouts, Bent Elevations, and Longitudinal Bracing Plans
  • Thermal and Friction Load Application Calculation Sheets
  • Detailed Connection Designs for Bents, Splices, and Cantilevers
  • Pipe Anchor and Guide Structural Attachment Details
  • Foundation Reaction Tables with Thermal Load Cases

Frequently Asked Engineering Questions

How do you model piping thermal friction forces?

We apply directional friction coefficients (typically 0.3 for steel-on-steel, 0.1 for PTFE) coupled with anchor forces supplied by the piping stress analysis team.

Can you design modularized pipe racks that are pre-assembled off-site?

Yes, we optimize segment lengths, lifting lugs, and transport splice joints so entire rack modules can be trucked and lifted directly onto foundations.
