Description

Rubber Bellow with Floating Flange – Flexible Expansion Joints

Overview

Rubber bellows with floating  flanges feature a rubber body with separate metal flanges that are not bonded to the rubber. The floating flange design allows for easier installation on existing piping systems, compensates for angular misalignment and simplifies replacement. Ideal for retrofit applications and installations where precise alignment is difficult.

Features

  • Rubber body with floating flanges
  • Flanges can rotate and adjust during installation
  • Single arch or double arch configurations
  • EPDM, natural rubber or nitrile compounds
  • Optional control rods and tie rods
  • Vacuum ring support for suction applications
  • Pressure tested before shipment

Applications

  • HVAC retrofit and replacement projects
  • Pump connections (suction and discharge)
  • Existing piping requiring flexible joints
  • Applications with angular misalignment
  • Maintenance and repair installations
  • Cooling tower and condenser water lines
  • Chilled water distribution piping
  • Industrial water and process piping
  • Fire sprinkler and fire fighting systems

Technical Specifications

  • Rubber Material: EPDM (water), Nitrile NBR (oil), Neoprene
  • Flange Standards: ANSI 150#, BS10 PN10/PN16, BS4504
  • Size Range: DN32 (1¼”) to DN600 (24″)
  • Pressure Rating: Up to 25 bar depending on size and construction

Advantages of Floating Flanges

  • Easier installation – flanges adjust to piping
  • Compensates for angular misalignment
  • Ideal for retrofit and replacement work
  • No need for precise pipe alignment
  • Simplifies field installation
  • Reduces installation time and labor
  • Allows for future piping adjustments

Benefits

  • Easy installation without precise alignment
  • Absorbs thermal expansion in piping
  • Reduces pump vibration transmission
  • Compensates for piping misalignment and settlement
  • Protects equipment from piping stress
  • Cost-effective flexibility solution
  • Suitable for retrofit and repair work
  • Long service life with proper installation
  • Easy to replace without pipe cutting
