Functional engineering application
The 2 Inch (DN50) Single Sphere Rubber Expansion Joint is an economical and compact flexible pipe connector designed to isolate pump vibration, absorb thermal pipe growth, and reduce noise in industrial piping systems. Formed from high-grade EPDM rubber reinforced with nylon cord and steel wire beads, this single-arch joint connects directly to pump suction and discharge flanges, preventing vibration transmission into rigid boiler headers and building structures. Supplied with floating 2" PN16 carbon steel flanges rated for 16 Bar operating pressure and temperatures up to 110°C.
Compact 2" (DN50) PN16 single sphere EPDM rubber expansion joint with galvanized flanges for pump vibration dampening & thermal expansion.
