IRIS Inspection

We at Global Boiler Aalborg are able to conduct inspections using the Internal Rotary Inspection System (IRIS) technique. An IRIS inspection is a very accurate inspection method where it’s possible to measure wall thickness down to 0.1mm accuracy. The accuracy achieved is dependent on the cleanliness and the dimensions of the tube measured. This can create a 3D image of the defects found during the inspection and give a detailed profile of the defect and its depth. 

The inspection can be done in both ferromagnetic and non-ferromagnetic tubes.  To ensure a precise inspection, a cleaning of the tubes might be necessary beforehand.

Valve Overhaul

We do overhaul on most sizes of globe valves and assist in replacing valve spare parts for your boiler system. Additionally, we also do replacement of major welded valves such as main steam valves for turbine vessels. 

The main benefits of giving your valves an overhaul and keeping them in good operating conditions are: 

  • Improving your boiler plant’s efficiency and safety by ensuring your valves are functioning correctly and have no leaks or restrictions of water or steam.  
  • Extended lifespan by regularly maintaining your valves parts and reducing corrosion. 
  • Reduced downtime by detecting defects before they cause major malfunction. 
  • Saving operational costs by reducing the overall cost associated with your boiler’s operation as it reduces the need for more extensive and expensive repairs. 

We are able to do overhaul on most sizes of globe valves and assist in replacing valve spare parts for your boiler system. And for larger boilers we are as well experienced in replacing major welded valves like main steam valves for turbine vessels.
