Proco Style 440-BD Molded Expansion Joints

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 a minimal cost

Elimination of electrolysis

Protection against start-up and surge forces
