Industrial Manufacturing Inspection Services

Independent inspection across fabrication, assembly, welding, coating, dimensional verification, documentation, testing, FAT, supplier surveillance and final inspection for manufactured industrial equipment.

Industrial manufacturers work across different materials, fabrication processes, standards and client requirements.

Dilenza provides qualified inspectors at manufacturers, suppliers and fabrication facilities worldwide, covering welding and coating inspection alongside dimensional verification, documentation review, test witnessing, FAT attendance and final inspection.

Inspector profiles are selected according to the equipment, manufacturing process, applicable standards, technical scope, location and required inspection duration.

Inspection at Industrial Manufacturers

Manufacturing inspection should follow the product and fabrication process.

One supplier may require inspection at a single final hold point.

Another may require recurring welding and coating surveillance throughout several months of production.

Vendor Inspection at Fabrication Facilities

Industrial projects frequently purchase equipment from manufacturers located away from the final project site.

Third-party inspection gives the client technical visibility while the equipment is still being produced.

A typical manufacturing sequence may involve:

  1. 01Material Receipt
  2. 02Fabrication
  3. 03Fit-Up
  4. 04Welding
  5. 05NDT
  6. 06Dimensional Inspection
  7. 07Coating
  8. 08Testing
  9. 09Final Inspection
  10. 10Documentation

Inspection can be organized around specific ITP points or maintained through recurring or resident coverage.

Final verification

FAT & Final Manufacturing Inspection

Where assigned, inspectors can support final manufacturing stages such as:

  • Final visual inspection
  • Dimensional verification
  • Documentation review
  • Functional or project-specific test witnessing
  • Factory Acceptance Test witnessing
  • Coating final inspection
  • Punch-list follow-up
  • Pre-shipment inspection

The exact FAT or release responsibility must always be defined by the project.
