International Standards:

  • ASME B16.9(U.S. Standard):Class 150, 300
  • EN 1092-1(European Standard): PN6 to PN16.
  • JIS B2312(Japanese Industrial Standard):5K to 16K
  • GOST 12815-80(Russian/CIS Standard): 0.1 MPa to 0.6 MPa
  • SABS 1123(South African Standard): PN6 to PN16.
  • DIN 8603 : PN6 to PN16.
  • BS 6121(British Standard): PN6 to PN16.

 

Pros:

  • ​Vibration Damping​​: Absorbs mechanical vibrations from pumps, compressors, or engines.
  • ​Thermal Expansion Compensation​​: Accommodates pipe movement due to temperature changes.
  • ​Misalignment Tolerance​​: Corrects minor installation offsets without stressing the system.
  • ​Noise Reduction​​: Minimizes fluid-induced noise in pipelines.
  • ​Easy Installation​​: Simplifies assembly in hard-to-reach or complex layouts.

Cons:

  • ​Pressure Limitations​​: Typically limited to ​​PN16/Class 150​​; unsuitable for high-pressure systems.
  • ​Material Degradation​​: Rubber/elastomer parts degrade under UV, high temperatures (>80°C), or aggressive chemicals.
  • ​Reduced Flow Efficiency​​: Bellows or flexible liners may create turbulence or pressure drops.
  • ​Maintenance Requirements​​: Periodic replacement of flexible elements due to wear.
  • ​Cost​​: Higher initial cost compared to rigid flanges.

Description

A ​​Flexible Joint Flange​​ (or ​​Flange-Mounted Expansion Joint​​) is a type of flange assembly integrated with a flexible element (e.g., rubber, PTFE, or metal bellows) to absorb vibrations, thermal expansion, or misalignment in piping systems. It combines the sealing capability of a flange with the flexibility of a compensator, ideal for systems exposed to movement or stress.
