Expansion joints are necessary in systems that convey high temperature or pressurized commodities in the form of liquid, steam or exhaust gases.

Bellows are a common type of expansion joint for a pipe system. As you probably notice, a bellows consist of a series of convolutions (ribs). The convolutions handle the internal pressures of the application. The key is the flexibility of the bellows allowing it to accept movement or changes in position of one or both ends.

  • Power Generation
  • Co-Generation, Petrochemical
  • Chemical Processing
  • Pulp Paper Manufacturing
  • Cryogenic Process
  • Pressure Vessel and heat Exchanger Fabricators
  • Heat Steam recovery Generator
  • Architect Engineering
  • Construction Engineering
  • Mechanical contractor
  • Pharmaceutical manufacturing
  • Gas Turbine, Gas Transmission
  • Ship building and Repair
  • Diesel Engine Mfg, Incineration
