District Heating NDT

District Heating NDT Services

​

In district heating systems, reliable and safe operation is crucial for maintaining energy efficiency and delivering uninterrupted service. Our specialised Non-Destructive Testing (NDT) services for district heating are designed to ensure the structural integrity and safety of these systems, helping to identify potential issues before they lead to costly or hazardous failures.

What is District Heating?

 

District Heating is a system in which water is heated at a central location and distributed through a network of highly insulated pipes to provide heating to homes, businesses, and public buildings. This approach is highly efficient, allowing a single system to serve multiple users across a wider area.

Is District Heating New?

 

While District Heating isn’t new—it dates back to ancient times, with Romans using similar methods to heat their baths—modern systems have evolved significantly. Today, new, efficient district heating systems are being installed across the UK, with approximately half a million connections already in place.

NDT Methods for District Heating Systems

 

The most effective way to inspect district heating pipework combines Phased Array Ultrasonic Testing (PAUT) and Magnetic Particle Inspection (MPI). This combination provides a comprehensive inspection of the weld root, body, and cap, making it possible to identify any defects in the weld or heat-affected zones.

​​

  • Phased Array Ultrasonic Testing (PAUT): An advanced ultrasonic method that creates detailed images of the pipe’s internal structure, PAUT is particularly effective for inspecting the weld root and detecting internal flaws.

  • Ultrasonic Testing (UT): Provides a reliable means of detecting wall thinning, corrosion, and other internal defects that can compromise the integrity of district heating pipes.

  • Magnetic Particle Inspection (MPI): Ideal for identifying surface and near-surface cracks in ferromagnetic materials, MPI helps detect flaws that could pose serious issues if left unaddressed.
