Power Generation Welding & Coating Inspection
Third-party welding and protective coating inspection for power plants, piping, boilers, fabricated equipment, structural steel and supporting systems.
Dilenza provides qualified welding and coating inspectors for power-generation projects at manufacturers, fabrication shops, construction sites and operating facilities worldwide.
Inspector profiles are selected according to the equipment, materials, applicable standards, project phase, location and required duration.
Inspection for Power Generation Projects
Power-generation projects combine different technical systems and operating conditions.
A boiler manufacturer may require welding surveillance throughout fabrication. Structural steel and external equipment may require coating inspection during surface preparation and application. Shutdown work may require temporary inspectors for repairs, testing and final verification.
Dilenza structures inspection around the actual project requirement.
