Hot Inspection Service

Hot Inspection Service

Is there an issue with your high temperature fixed equipment, but you can’t see the cause, or the exact site? We designed and developed Cetek’s Lancescope™ heater inspection tool for just this situation. It allows to undertake a high temperature furnace inspection to determine the scope of the problem, often avoiding an expensive shut down of the heater.

Cetek’s Lancescope™ system provides real-time, close-up or wide-angle views of virtually any area inside a fired heater, or other high temperature equipment while it is still operating. The hot inspection system uses a state-of-the-art digital camera system, which provides clear, detailed images of problem areas up to 3000°F (1650°C). The furnace inspection system can be inserted into openings as small as 2.75” (7cm) and reach up to 30ft (10m). In applications below 1000°F (540°C), the heater inspection system provides illumination via a high temperature light source for optimum clarity.

Benefits of the Lancescope™ Hot Furnace Inspection Process

  • Performed while unit is in operation
  • Provides insight for production availability
  • Identifies damage in early stages
  • Reduces maintenance costs
  • Minimizes repair down time
  • Maximizes production

The Lancescope™ technology is supplemented by a complete infrared thermography analysis, temperature tests, and emissivity measurements.
Infrared Thermography – we employ infrared technology to inspect furnace process tube surfaces to primarily identify the degree of oxidation and scale formation.

Thorough inspection provides data needed for other Hot-tek on-line services.
