FW-Fernwärme

Service

Certified. Traceable. Reliable.

“FW Service supports projects throughout all phases of pipeline construction — from technical design to commissioning and ongoing operational support. The focus is on technically tailored solutions for district heating, industry and energy systems. Planning, examination, evacuation, leak detection and renovation are project-specific and tailored to the respective system requirements.”

Technical Dimensioning

  • Plant-specific execution planning
  • Static calculations for pipes
  • Heat and pressure loss calculations
  • Determination of insulation thicknesses and casing pipe diameters
  • Optimisation of temperature-induced linear expansion
  • Dimensioning of leak detection systems
  • Dimensioning of trace heating and vacuum systems

Thermal Pre-Stressing

  • Planning and implementation of thermal pre-stressing
  • Dimensioning for operation without  a compensator
  • Also applicable to preinsulated pipelines

Site Supervision

  • Determine quality management and inspection scope
  • Coordination with planners, developers and clients
  • Documentation of the systems
  • Supervision of prefabrication and on-site processes
  • Radiographic examination

Leak Detection

  • Localisation of leaks in district heating networks
  • Detection of moisture in the ring space
  • Mobile measurement technology for existing and new installations
  • Support with damage analysis and network assessment
  • Documentation of measurement results and damaged areas
  • Support with maintenance and renovation

Evacuation

  • Evacuation of SIS pipe systems prior to commissioning
  • Leak-tightness test of the casing pipe during evacuation
  • Evacuation of the ring space to ≤ 1 mbar
  • Mobile vacuum pump systems for use on construction sites
  • Pressure and condition monitoring of the ring space
  • Project-specific dimensioning and support for the vacuum sections

Renovation

  • Analysis and assessment of existing networks
  • Renovation of district heating pipelines
  • Planning and implementation of cathodic corrosion protection systems
  • Retrospective optimisation of existing systems
