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.
