Proco Style 440-BE

The Proco Style 440-BE Molded Expansion Joints can be used for corrosive applications that are found in industries such as chemical-petrochemical, industrial process piping systems, power generation plants, pulp/paper plants, water and wastewater sewage, and pollution control systems. Wherever metallic joints, lap joints, or PTFE and FEP-lined rubber expansion joints were previously used, the Proco Style 440-BE can also be used.

Some notable features of the Proco Style 440 BE include:

  • Absorption of pipe-wall and fluid-borne noise
  • Reduction of system stress and strain
  • Isolation of mechanical vibration and motion
  • Superior “Flex Life” and strength
  • Tested force pound and spring rate tables
  • Coated flanges and factory set limit bolts
  • Chemical service capability at minimal cost
  • Elimination of electrolysis
  • Protection against start up and surge forces

For more information about the features and benefits of the Proco Style 440 BE, download our brochure.
