  • The Proco Style 442-BD 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. This expansion joint features two convolutions for minimal movements, higher pressure/temperature ratings, and short face-to-face opening requirements. Wherever metallic joints, lap joints, or PTFE and FEP-lined rubber expansion joints were previously used, the Proco Style 442-BD can also be used.

    Some notable features of the Proco Style 442-BD 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 a minimal cost
    • Elimination of electrolysis
    • Protection against start-up and surge forces
