Pipe spool fabrication

Carbon steel, stainless steel and specialty alloy pipe spools for U.S. process piping projects, with inspection and documentation to your specification.

Stainless piping spools supported on a fabrication rack

Rigid Welding fabricates pipe spools from project drawings and isometrics, bringing pipe, fittings and flanges together into assemblies ready for the next stage of installation. We work in carbon steel, stainless steel and specialty alloys. The applicable ASME B31 requirements, welding procedures, inspection scope and documentation are reviewed against your project specification before fabrication.

What we deliver

  • Process piping spools and prefabricated piping modules
  • Carbon steel, stainless steel and specialty alloy piping
  • Welding procedures and personnel qualified under ASME Section IX
  • Material traceability, weld records and inspection documentation
  • NDE coordination and pressure testing to the agreed inspection plan

Define the spool package

A spool package needs more than an overall pipe route. Identify the individual assemblies, connection points and drawing revisions so the fabrication scope can be compared against your installation plan. State which materials and components you will supply and which you want included in the quotation. If drawings are still being developed, identify the open dimensions or design decisions when you submit them.

  • Isometrics or fabrication drawings with spool numbers and revision status
  • Pipe sizes, schedules, material grades, fitting details and flange specifications
  • Quantities, connection details and dimensions that control field fit-up
  • Applicable piping code, project specifications and required delivery date

Plan inspection and records before welding

The required examination and testing depend on the piping code and your project specification. Include the inspection and test plan with your RFQ where available, including witness or hold points and any customer review requirements. This lets the quotation account for the required inspections and records before production starts.

  • Material traceability and required material records
  • Welding procedure requirements, weld identification and weld records
  • NDE methods and extent specified for the project
  • Pressure test requirements and the final manufacturing data package

Coordinate fabrication with installation

Tell us how the spools fit into your wider piping package. Flag field-weld connections, mating equipment and any dimensions that need confirmation before release. Include the delivery destination and whether the order has multiple delivery stages. We review these requirements with the drawings and confirm the quoted scope and schedule with your team. For piping supplied as part of a framed assembly, our process skid fabrication service covers the related module and equipment-frame scope.

FAQ

Questions about pipe spool fabrication

Don’t see yours? Call 818-669-9999.

What should I upload for a pipe spool fabrication quote?

Upload the current isometrics or fabrication drawings and include quantities, pipe sizes and schedules, material grades, applicable project specifications, inspection requirements and the required delivery date. Note any dimensions or design decisions that are still open.

Can you fabricate stainless steel and carbon steel pipe spools?

Yes. Our process piping capabilities include stainless steel, carbon steel and specialty alloys. Include the required grades, pipe schedule and service requirements so we can review the material and welding scope for your package.

Are inspection and pressure testing included in every spool quote?

The examination and testing scope is defined by the applicable code, project specification and agreed inspection plan. Include your requirements with the RFQ so the quotation identifies the testing, records and review points included.

Can you help when fabrication drawings are incomplete?

Our engineering capabilities include construction drawings, material selection and joint design. Send the information you have and identify the gaps so we can review what engineering work is needed before fabrication.
