Expansion Joints are mainly used in Pipelines to Offset Vibrations or Movements from Equipment, Thermal Movements or any other movements in the line. Basic movements could be Axial, Angular or Lateral and Joints are available in Rubber and Stainless steel based on the medium. Typical applications would be Commercial and Residential Chilled water pipelines.

Flexible connectors are used to absorb thermal and seismic movement, absorbing hydraulic shock, provide vibration and noise dampening, ease installation and correct minor misalignments of piping and components. They come in a variety of sizes, materials, and connection ends for numerous applications. The inner hose is an annular design, an annular hose is better suited for pump connections as it can better sustain torsion stress due to longitudinal expansion from rises in pressure. Metal wire braid on a hose assembly restrains against hose elongation under higher pressures and acts to dampen vibration. Abrasion resistance is also increased by a heavy braid. Optimal braid coverage will contain the core under pressure and reduce the possibility of twisting and squirming.

The use of threaded metal connectors for an application like pumps, compressors and other mechanical equipment can enhance the overall operation of a system. They have the advantages of –

  • Longer service life
  • Increased pressure capacity
  • Greater fatigue resistance due to flex
  • Increased temperature capacity of media
  • Greater protection of the annular hose
  • Acceptance of thermal expansion

Flanged flexible connectors are used for connecting pipes and equipment where flanged ends are preferred. They are recommended to compensate for vibration, thermal growth, motion, misalignment, and pressure stress and noise reduction in piping. Applicable fluids include water, sea water, steam, acids, alkaline, oils, etc.

Features –

  • Reduces stress
  • Normal mechanical equipment vibrations are reduced at the connector
  • High pipe vibration noise is greatly reduced
  • Eliminates shelf life problems and allows operation at elevated temperatures
  • Excellent protection for adjacent piping and equipment

Tied Flanged Flexible Connectors are designed to be installed onto vibrating equipment to reduce the transmission of noise and vibration to the attached pipeline system. They are designed for use when the system pressure, temperature or flow media is unsuitable for the use of rubber pump flexible connectors. All stainless steel to wetted parts with loose swivel plated carbon steel flanges.

Suitable application areas - HVAC Systems, Air Compressors, Plumbing Systems, Pumps, Hot Air Pipelines, Chemical Factories, Industrial Factories, Marine Applications.
