Pipe Spool Fabrication

What a pipe spool is, and why it is fabricated off site

A pipe spool is a prefabricated assembly of pipe, fittings and flanges, built to an isometric drawing and shipped as one piece. Building it in a shop instead of in the field changes three things:

• Weld quality is controlled. Position welding in a fabrication bay beats overhead welding on a scaffold, and automated processes become available.
• Testing happens before the spool ships. Hydro and pneumatic testing in the shop finds a problem while it is still cheap to fix.
• Field time collapses. Site work reduces to setting, bolting and tying in, which is the expensive part of the schedule.

Materials and scope we fabricate

• Carbon and stainless steel piping, to the pipe classes your specification calls for
• Modular piping skids and modular data center skids, assembled and tested as units
• Water infrastructure piping
• Environmentally sensitive piping, where containment and documentation matter
• Instrumentation and tubing, installed with the spool rather than after it
• Launcher and receiver assemblies, and valve modifications

The shop and the equipment behind the welds

Our fabrication facility covers 700,000 square feet across 88 acres and is served directly by the Rochester and Southern short line railroad, so oversized assemblies leave by rail rather than being cut down to fit a truck.

The equipment decides what we can hold to tolerance: a PythonX CNC plasma cutting system, a Ficep Gemini plate processor, Ficep Gemini HPE, CNC tube benders, and sub arc and automated welders. Automated welding matters on spool work because repeatability is what keeps a large package consistent from the first joint to the last.

Welding codes and certifications

Pipe spool fabrication is a documentation exercise as much as a welding one. Ask any fabricator to name their stamps before you send drawings. Ours are:

• ASME “U”, “S” and “PP” stamps, with NBIC “R” for repairs
• API 1104 for pipeline welding
• AWS D1.1 and D1.5 for structural and bridge welding
• AISC Fracture Critical and AISC Bridge Fabricator, Advanced
• DOT certified in New York, North Carolina, Pennsylvania and Massachusetts

Process piping design follows the ASME B31 family, and our welders qualify to the procedures those codes require.

Testing, coating and what ships

A spool that arrives untested is a spool you will test on site, at site rates. We self-perform hydro and pneumatic testing, torquing and tensioning, tubing and instrumentation, mechanical detailing, and painting and coating with NACE certified painters and blasters. Spools ship tested, coated and marked against the isometric they were built from.

Fabrication and installation from one contractor

Most fabricators hand off at the loading dock. We carry the scope through mechanical installation, including millwright services for the rotating equipment the piping connects to, across oil and gas and power generation and data centers.

That single line of accountability is the argument for using a fabricator who also installs. When a spool does not fit, there is nobody to blame and therefore nobody to wait for.

What to ask a pipe spool fabricator

Which stamps do you hold? ASME and NBIC are verifiable. Ask for the certificate numbers.

Do you test before shipping, and who pays if it fails on site? The answer tells you where the risk actually sits.

Can you install what you fabricate? A fabricator who cannot install is a fabricator whose errors become your schedule problem.
