DISTRICT HEATING EXPANSION JOINTS

 

District heating pipelines are mainly exposed to temperature expansions caused by temperature fluctuations as a result of a system start-up
or predisposed operating conditions. Depending on the purpose district heating expansion joints can be divided into two main categories:

  • District heating expansion joints for multiple usage
  • One-step expansion joints

Both types are specifically developed for district heating applications and are suitable for ground-surface and underground pipeline systems. Belman offers standard as well as customised solutions.

DIMENSION & DESIGN

District heating expansion joints are available in sizes DN 80 – 1200 in all materials.
Other sizes and designs are designed and manufactured as cost-efficient customised solutions based on customer specifications
and drawings.
