Fabricated Pipe and Pipe Fitting Manufacturing

NAICS 332996 · Fabricated Metal Product Manufacturing · SBA size standard: 550 employees

Fabricated pipe and pipe fitting manufacturers take custom specifications for cut, bent, welded and threaded pipe assemblies used in industrial, commercial and municipal projects. For a shop that receives drawings for pipe spools, manifolds, elbows and fittings, the specialists turn incoming orders into cut lists and weld schedules, track raw pipe and fittings inventory, schedule shop and field work, generate pressure-test and inspection packets, and keep material traceability and welder qualification records. Welding procedures, material certifications and code stamps remain with the welders and quality control personnel.

Workflows

Order and drawing intake

Starts when: A customer sends a purchase order with drawings or specifications

  1. Capture the project name, drawing revisions, pipe sizes, schedules, materials and quantities
  2. Verify the order against approved product list and shop capabilities
  3. Confirm delivery or installation date against current shop backlog
  4. Create a job folder with all drawings and specifications
  5. Draft acknowledgment and request for any missing information

Watch for: Drawings must be the latest revision and any changes flagged; Special materials or coatings must be identified immediately

Cut list and bill of materials creation

Starts when: After order acknowledgment and drawing approval

  1. Explode the isometric or spool drawings into a detailed cut list by length and quantity
  2. Add allowances for weld preparation and fit-up
  3. Generate bill of materials for pipe, fittings, flanges and consumables
  4. Cross-reference with current inventory and flag shortages
  5. Output cut sheets for saws and CNC equipment

Watch for: Pipe lengths must account for precise end-prep and weld gaps; Material heat numbers must be assigned from available stock

Shop fabrication scheduling

Starts when: After cut list approval and material availability confirmed

  1. Sequence spools by delivery priority and welding process
  2. Assign welding stations, positions and qualified welders
  3. Build a daily and weekly shop schedule with milestones for fit-up, weld, test and coat
  4. Coordinate with coating and inspection steps
  5. Update schedule when customer changes delivery dates

Watch for: Weld procedure and position restrictions limit station availability; Backlog visibility needed for new order quoting

Material purchasing and inventory

Starts when: Weekly and when cut list shows shortages

  1. Calculate total material needs from active and forecasted jobs
  2. Subtract current inventory with correct heat numbers and certifications
  3. Draft purchase orders for pipe, fittings, flanges and weld wire
  4. Track incoming material against certifications and test reports
  5. Maintain minimum stock for common sizes and emergency orders

Watch for: Mill test reports and material certifications required before use; Pipe and fittings often purchased in mill quantities with long lead times

Welding and quality documentation

Starts when: Daily during fabrication and on milestone completion

  1. Generate welder assignment sheets with qualified procedures
  2. Create weld maps showing joint locations and process
  3. Log welders, dates, filler materials and inspection results
  4. Prepare traveler packets with MTRs, weld maps and test reports
  5. Track welder qualification expiration dates

Watch for: Full traceability from raw material to finished spool required; Different codes apply depending on service

Testing, inspection and release

Starts when: After welding completion and before shipment

  1. Schedule hydrostatic, pneumatic or NDE tests per specification
  2. Draft test procedures and data sheets for approval
  3. Compile inspection and test reports into release packet
  4. Coordinate third-party inspector visits and sign-offs
  5. Generate final documentation package for customer

Watch for: Test pressures and hold times dictated by code and specification; Repairs require retesting and updated documentation

Shipping and field coordination

Starts when: After final inspection and customer release

  1. Group spools by delivery location and sequence
  2. Draft packing lists, bills of lading and shipping tags
  3. Schedule truck or rail transport with required permits
  4. Draft delivery notifications and site readiness requests
  5. Record delivery confirmation and any damage

Watch for: Large spools may require oversize load permits and escorts; Pipe must be protected from damage during transit

Permit and regulatory paperwork

Starts when: On project start and at each milestone

  1. Generate required permit applications for shop and field work
  2. Track inspection and approval dates from local authorities
  3. Maintain logs of welder qualifications and procedure qualifications
  4. Prepare renewal reminders for licenses and certifications
  5. Compile daily safety and compliance checklists

Watch for: Requirements vary by jurisdiction and project type; All filings and approvals are reviewed by the quality manager
