- Expansion joint & Flexible joint
Style FA311 (Type FA-CB)
A flange adapter designed to absorb expansion.
A double-pipe, sliding-type expansion joint consisting of a socket slightly larger than the main pipe with a flanged connection, a spigot pipe inserted into the socket and connected to the main pipe, a specially shaped rubber ring with an automatic sealing mechanism to seal the gap between the two pipes, a housing to retain the rubber ring, and bolts that fasten the split housing together.
It is designed for an operating pressure of up to 1 MPa. Performance and specifications can be tailored to suit specific operating conditions.
| Available Sizes | 80A–2400A *Other sizes are also available upon request.* |
|---|---|
| Operating Pressure | Operating Pressure: 1.0 MPa (10 kgf/cm²) Test Pressure: 1.5 MPa (15 kgf/cm²) |
| Material | Housing: FCD450, etc. Bolts/Nuts: SS400, etc. Spigot Pipe/Socket Pipe: SS400, etc. Rubber: SBR, etc. |
| Coating | Internal/External Surfaces: Liquid epoxy resin coating for water supply Bolts/Nuts: Hot-dip galvanized *Other coating options are also available upon request.* |
