Frequently Asked Questions
What sizes are available?
These expansion joints are available from DN25 to DN600, covering nominal bore sizes from 1 to 24 inches. Custom sizes may be produced on request by contacting our technical team.
Can these expansion joints be used in seawater applications?
Yes, the rubber bellow is available in EPDM or Neoprene compounds that provide excellent resistance to seawater and are specifically recommended for marine environments. For oil or fuel applications, NBR material should be selected.
Are the flanges drilled to DIN standard?
The flanges are manufactured to DIN 2576 (EN 1092-1) standard, ensuring a perfect match to standard PN10 or PN16 flange dimensions. Custom drilling patterns can also be accommodated upon request.
What is the maximum operating temperature and pressure?
Standard joints are rated up to PN16 and can operate within -10°C to +100°C. For higher pressures or extreme temperatures, reinforced options with stainless steel rings are available, but these should be confirmed based on your specific system requirements.
