Dilenza provides third-party inspection services in China for industrial equipment, fabrication facilities, shipyards and engineered project packages.
We match qualified inspectors to the equipment, ITP, applicable standard, supplier location and required inspection responsibility.

Inspection Coverage Across China
Manufacturers · Fabrication Facilities · Shipyards · Equipment Suppliers · Project Sites
Not sure which qualification is required? Send us the technical scope and we can review the requirement.
Industrial projects require more than a generic factory visit. Dilenza supports technical inspection at Chinese suppliers where equipment, manufacturing stages, testing, documentation and acceptance criteria must be reviewed against the agreed project scope.
Pressure Vessels · Heat Exchangers · Boilers · Columns · Process Equipment
Inspection requirements may involve fabrication stages, welding, NDT witnessing, pressure testing, dimensional verification and documentation review according to the applicable ITP.
Process Piping · Line Pipe · Valves · Fittings · Skids
Support can be structured around manufacturing milestones, testing and project-defined witness points.
Pumps · Compressors · Turbines · Mechanical Equipment · Industrial Assemblies
Inspector selection should reflect the actual mechanical equipment and agreed inspection responsibilities.
Steel Structures · Modules · Platforms · Heavy Welded Assemblies
Suitable for projects requiring welding surveillance, dimensional verification, fabrication inspection or protective coating inspection.
Vessel Structures · Ship Equipment · Offshore Modules · Marine Fabrication
China continues to strengthen major shipbuilding and marine-engineering clusters, with current industrial development concentrated across the Yangtze River Delta, Bohai Rim and Pearl River Delta.
Power Equipment · Energy Systems · Renewable Equipment · Fabricated Project Packages
Inspection can support individual manufacturing milestones or longer production programs.
For industrial procurement, inspection often needs to happen before manufacturing is complete.
Dilenza can support independent vendor inspection in China according to the client's ITP, purchase-order requirements and project specification.
Unlike generic consumer-product inspection, industrial vendor inspection may follow specific technical milestones.
Project-defined manufacturing and quality documentation can form part of the inspection scope.
Inspection attendance before work proceeds beyond defined project stages.
Witnessing manufacturing activities or testing according to the approved ITP.
Recurring technical presence throughout fabrication or production.
Inspection personnel can witness project-defined testing according to the agreed scope.
Technical attendance during defined FAT activities can be arranged where appropriate to the project.
Inspection before manufacturing completion or project-defined release stages.
Qualified welding inspection profiles for industrial fabrication, equipment manufacturing, shipbuilding and project sites.
AWS CWI · CSWIP · IWI · Project-Specific Experience
Protective coating inspection for marine, structural, energy, process-industry and fabricated equipment.
AMPP · FROSIO · BGAS-CSWIP · Project-Specific Experience
Dilenza does not approach industrial inspection as a generic factory visit.
The required profile can depend on the equipment, manufacturing process, material, applicable standard, inspection responsibilities and project-specific qualification requirements.
Location · Equipment · ITP · Standards · Qualification · Dates
We identify the technical experience and qualification required for the assignment.
Profiles can be considered based on: Certification · Equipment Experience · Industry Experience · Location · Availability
Relevant inspector profiles can be submitted for client technical assessment.
The confirmed inspector attends according to the agreed scope and schedule.
The factory defines the location. The equipment defines the expertise.
China's industrial scale means that a country page should not be organized around a single city.
Dilenza can review requirements throughout major manufacturing regions according to the actual supplier location and required technical profile.
Inspection requirements can be reviewed throughout China. Highlighted areas represent major industrial clusters, not Dilenza offices.
