Shop-Fabricated and Field-Fabricated Process Piping
Overview Process piping systems are built using two primary fabrication strategies: shop fabrication and field fabrication. Each approach has distinct advantages, limitations, and best-use scenarios. Selecting the correct approach depends on project scale, site conditions, schedule, quality requirements, cost targets, and safety constraints.
Shop Fabricated Process Piping Definition Shop fabrication is the construction and assembly of piping components in a controlled fabrication facility (shop) prior to delivery and installation at the site. It includes cutting, welding, fitting, support assembly, testing, coating, and preassembly of spools and modules.
Advantages
Controlled environment: Better quality control, consistent welding conditions, protection from weather, and reduced contamination.
Higher productivity: Skilled crews, dedicated equipment, and repetitive tasks increase efficiency and throughput.
Improved quality and code compliance: Easier inspection, radiography, hydrostatic testing, and documentation.
Reduced site labor and congestion: Minimizes on-site welding, scaffolding, and hot work.
Shorter site schedule: Preassembly allows faster installation and commissioning.
Safer work conditions: Fewer field hot-work operations and less exposure to site hazards.
Better logistics for complex modules: Piping racks, headers, and skids can be delivered as larger preassembled units.
Typical Applications
Repetitive spools and piping runs (chemical, refinery, and process plants)
Skid-mounted process modules
High-spec systems needing strict quality control (high-pressure, hazardous services)
Best Practices
Complete accurate 3D models and isometrics prior to shop fabrication.
Perform site surveys and mock-ups to confirm clearances and interfaces.
Plan spools for transportable sizes and include field weld joints for tie-ins.
Coordinate coatings, insulation, and pre-testing before shipment.
Maintain traceability and QA documentation for each spool.
Field-Fabricated Process Piping Definition Field fabrication is the assembly, cutting, welding, threading and installation of piping at the project site. This includes final fit-up, welding to equipment or existing systems, supports and hangers installation, and final testing in place.
Advantages
Flexibility: Can adapt to as-built conditions, late changes, and complex site constraints.
No transport size limits: Large assemblies or long runs can be fabricated in place.
Lower initial coordination required: Useful when detailed shop drawings are not available.
Better for confined or inaccessible piping runs where preassembly would be impractical.
Typical Applications
Final tie-ins to equipment and existing systems
Long runs in congested or fixed infrastructure
Large bore piping that cannot be transported easily
Late-design changes and repair/retrofit work
Best Practices
Use pre-installation site surveys and establish clear as-built baselines.
Implement rigorous welding procedures, qualified welding personnel, and field QC plans.
Provide adequate shelter for weather-sensitive work and proper lighting for night operations.
Sequence field welding to minimize rework and interferences.
Maintain detailed NDE/inspection records and ensure traceability for materials and welders.
Hybrid Approaches Many projects use a hybrid approach, maximizing shop fabrication where feasible and relying on field fabrication for tie-ins, large assemblies, or adaptive needs. Typical hybrid strategies include:
Shop-fabricate spools sized for transport; finish tie-ins and final welding in the field.
Deliver preinsulated or pre-coated spools needing minimal on-site finishing.
Use modular skids built in shop; connect utilities and piping in the field.
Prefabricate supports and hanger assemblies in shop and install on site.
Selection Criteria Consider these factors when deciding between shop and field fabrication:
Project schedule and site labor availability
Transport logistics and lifting capacity
Complexity and repeatability of piping spools
Quality requirements and inspection regime
