Industrial Piping Engineering Workflow
Use this workflow to move from operating conditions and piping geometry into a technically complete product selection or RFQ. Flexible metal hose, expansion joints, compensators, seismic loops, guides, anchors, and supports should be selected from the actual service conditions—not from nominal size or product category alone.
1. Define the Service Conditions
- Pipe or hose nominal size, schedule, and material.
- Normal, design, and upset pressure and temperature.
- Process media, corrosion, cleaning, and compatibility requirements.
- Installed geometry, available envelope, and equipment connections.
- Movement type: vibration, axial, lateral, angular, seismic, or installation flexibility.
- Cycle frequency, expected service cycles, transients, and startup/shutdown conditions.
2. Establish the Engineering Inputs
- Metal Hose Pressure Derating Calculator for temperature-adjusted pressure review using validated base data.
- Pipe Thermal Expansion Calculator for preliminary pipe growth.
- Thermal Expansion & Offset Calculator for movement and preliminary hose geometry.
- Metal Hose Length & Bend Radius Calculator for lateral offset/live-length review.
- Velocity & Pressure Drop Calculator where flow conditions affect selection.
- Seismic Piping Data by ZIP Code for preliminary site-based seismic inputs.

3. Choose the Product Family
- Metal Hose Assemblies for supported flexible connections, vibration, offset, and fluid-transfer applications.
- Expansion Joints for application-specific piping movement.
- Pipe Compensators for controlled axial thermal movement.
- Seismic V-Loops for seismic and multi-axis movement.
- Pipe Guides & Slides and Anchor Clamps for controlled movement systems.
4. Verify Pressure, Movement & Installation
The selected product must be checked as a complete assembly. For metal hose, confirm hose series, braid count, fitting materials, welds, pressure, temperature, media, bend radius, live length, cycling, and installation geometry. For expansion systems, coordinate the expansion device with anchors, guides, supports, pressure thrust, spring force, and equipment loads.
Use Metal Hose Working Pressure & Temperature Selection, Pipe Guide Layout Review, and Advanced Piping System Review where applicable.
5. Prepare Specifications & Documentation
Use the Metal Hose Assembly Specification Guide and Division 23 Flexible Piping Specification Resource to define materials, dimensions, operating conditions, testing, tagging, MTRs, submittals, and project-specific documentation before production release.
6. Submit a Complete RFQ
Include product type, size, overall length, end connections, materials, pressure, temperature, media, movement, cycle requirements, quantity, documentation requirements, required ship date, and drawings. For piping systems, identify anchors, guides, supports, equipment connections, and the intended movement path.
