System solutions for reliable connections in plant engineering and construction.
Corrosive fluids, large movements, vibrations and a wide variety of pressure levels as well as extreme temperatures: The one who is responsible for plant engineering or equipment design must take many factors into consideration.
Customised solutions are essential in industrial engineering because of individual design criteria. High quality expansion joints supplied by Frenzelit are as practical as they are cost effective.
Available styles:
• Sealing surface with steel reinforcement for floating
flanges
• Back up bars with groves according to DIN PN 10/16
or ANSI 150lb
• Full face elastomer flanges with fabric reinforcement
• Back up bars with shoulder
• Male and female threads for size DN 15 - 80 mm
• Tie-rods
• Special tie rods for Lateral Expansion Joints
• Additional PTFE lining
• Vacuum supporting rings / spiral supports

Structural Engineering
Application areas for rubber compensators: Structural engineering
Rubber compensators are often used in structural installations, e.g. in air-conditioning and heating technology, for pressure booster systems and for drinking water supply systems. A special design is available for heating technology; it can be used at temperatures up to 130°C and is subject to self-monitoring to DIN 4809 as controlled by the German technical inspection agency.
