Flexibility in Your Rigid Piping Systems With Abra-Line
Garlock ABRA-LINE ™ rubber expansion joints offer superior performance, reliability and service life in your plant.
The ABRA-LINE™ family of products was developed for highly abrasive applications typically found in the power generation, fertilizer, mining and chemical industries. These may include flue gas desulphurization systems, phosphate mining, dry bulk power transfer systems, tailings and slurry applications. Their proprietary urethane formula was designed to reduce wear and extend service life.
Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:
- Absorb movement
- Improve thermal stability
- Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
- Reduce mechanical noise
- Compensate for misalignment
- Eliminate electrolysis between dissimilar metals
Garlock Style 404
Style 404 Expansion Joints are specially designed for full vacuum abrasive service applications. The tube material is a proprietary urethane formulation. Style 404 can be constructed as a single or multiple arch design. It can also connect pipe f langes in concentric or eccentric tapers, to join piping of unequal diameters.
Design of Garlock ABRA Expansion Joints
- Tube - Proprietary urethane formula for abrasive applications- Abrupt filled arch configuration provides maximum movement, and pressure and vacuum resistance in slurry application
- Body- Composite fabric construction with welded, treated metal body rings for dimensional stability and pressure/vacuum resistance
- Cover- Wide selection of elastomers available which are resistant to oxidation
