Gallagher Fluid Seals represents a number of expansion joint manufacturers, enabling us to provide an expansion joint for any piping system in any industry. The ABRA-LINE™ Rubber Expansion Joints from Garlock are meant for highly-abrasive applications.
The Garlock ABRA-LINE™ Style 4394 Rubber Expansion Joint is a multi-convoluted, lightweight expansion joint, designed for lower pressure applications that require significant amounts of movement, axially and/or laterally. Its low spring rates make it ideal for load cell, bin activator, vibrating bin, silo, and shaker boot applications. The below success story comes directly from Garlock and an application using the ABRA-LINE™ Style 4394 joints.
Expansion joints are specially engineered products inserted into a rigid piping system to do a number of jobs.
They absorb movement, relieve system strain due to thermal change, stress, pumping surges, wear, or settling, reduce mechanical noise, compensate for misalignment, and/or eliminate electrolysis between dissimilar metals.
When expansion joints are designed, applied, and installed correctly, it is not unusual to achieve a service life of 15-20 years in most industrial applications. Read on to see what our partners at Garlock had to say about troubleshooting in order to expand the life expectancy of nonmetallic expansion joints.
