Pre-insulated pipe leakage detection

Monitoring the condition of the insulation of pre-insulated pipes is useful in preventing possible major damage to the pipeline which most frequently occurs due to the loss of integrity of the casing and carrier pipe. Integrity defects in the casing and carrier pipe are predominantly caused by non-compliance with installation procedures and conditions for joint fitting, material defects, a poorly designed pipeline route, or damage caused by someone else (e.g. during installation or repair of other networks).

In order to monitor the condition of the insulation within pre-insulated pipe systems, or to detect leakage and facilitate repair, we fit our Wehotherm® pre-insulated pipes with Nordic detection wires compliant with EN 14 419 as standard. Upon request, we are able to supply pipeline systems with other types of detection wires (e.g. Brandes, Hagenuk and Isotronic, etc).

We offer the following services relating to monitoring the condition of the insulation within pre-insulated pipe systems:

  • baseline reflectometry measurements for new constructions
    as a basis for subsequent measurements (baseline)
  • regular check-up measurements of pre-insulated pipes
    (recommended twice a year)
  • location of leaks to facilitate repair of pre-insulated pipes
  • training and consultation services relating to monitoring the condition of the insulation of pre-insulated pipes
