​Stainless Steel Exhaust Bellows & Expansion Joints

Picture
Diesel  Expansion Joint (DEJ)
 
  • Exhaust bellows are used for absorbing  thermal  expansion  in exhaust,  gas ducting and low pressure  systems 
  • Standard  assemblies with flanges, weld ends or a combination of both
  • Pressure thrust  will be transmitted onto  pipeline. Correct anchoring  and guiding must be used
  • Internal flow liners for eliminating velocity and flow problems fitted as standard
  • Standard  working pressure  is 100 kPa 
  • Standard diameters up to 5000  mm are available on request
