Elastomeric Seal Joint Performance Flexible Sealing Solutions for High-Movement Industrial Systems

Written by

When movement magnitude exceeds conventional expansion joint capacity engineers encounter complex conditions involving multi-directional displacement under unpredictable patterns. 

Standard metallic and fabric expansion joints are designed for predictable axial thermal expansion, while HVAC ductwork water treatment pipelines and marine installations can experience horizontal movement, vertical displacement and angular rotation simultaneously during seismic events. 

Zepco LLC engineered elastomeric seal joints to address these high-movement challenges. These joints serve as specialists in flexibility and sealing integrity under extreme conditions.

Understanding the Movement Profile

High-movement industrial systems require a precise understanding of movement types magnitudes and combination patterns. Selecting an elastomeric seal joint begins with a detailed movement assessment.

Axial Compression and Extension

Axial movement occurs along the connection axis due to thermal expansion equipment growth or pressure changes. Typical magnitudes range from half an inch to six inches. 

Elastomeric seal joints accommodate this through single-arch designs capable of two inches and multi-arch configurations reaching six inches without stress concentration or buckling. They provide tens of thousands of movement cycles. Applications include long duct runs, high-temperature piping and equipment with thermal growth.

Lateral Offset

Lateral displacement moves side to side perpendicular to the connection axis and arises from building drift seismic events and foundation settlement. Magnitudes can reach eight inches. Elastomeric materials deform laterally while maintaining uniform stress distribution. 

Multi-arch designs increase lateral capacity while accommodating simultaneous axial movement. Applications include ducts crossing building expansion joints, settling structures and marine installations.

Angular Rotation

Angular rotation results from differential settling structural rotation or equipment misalignment and can range from one degree to fifteen degrees. Elastomeric seal joints compress on one side and extend on the other maintaining seal integrity throughout the angular range. This makes them suitable for bridge deck connections, rotating equipment and structures experiencing complex movement.

Combined Multi-Plane Displacement

Many systems undergo simultaneous axial lateral and angular displacement. A building expansion joint during a seismic event can experience three inches lateral two inches axial five degrees angular movement along with one inch daily thermal cycling. 

Metallic joints rated for axial movement experience stress under these conditions, and fabric joints endure attachment stress at angular points. Elastomeric seal joints manage all movement components independently, distributing stress evenly and maintaining sealing performance.

Performance Envelope Balancing Flexibility with Operating Conditions

Elastomeric seal joints excel in flexibility while operating within well-defined environmental and pressure limits.

Pressure capability ranges from five to fifteen PSI in standard designs, twenty-five to forty PSI in reinforced variants and up to sixty PSI in specialized constructions. They balance flexibility with moderate pressure applications where ductwork and low-pressure process piping benefit from movement accommodation. 

Temperature ranges depend on material selection. EPDM performs between minus forty and three hundred degrees Fahrenheit, Neoprene between minus forty and two hundred fifty degrees, Nitrile between minus thirty and two hundred fifty degrees, Viton between minus twenty and four hundred degrees and Silicone between minus sixty-five and four hundred fifty degrees. 

These ranges suit ambient to moderate industrial processes. Chemical compatibility allows material choices for water steam acid oils, fuels solvents and other industrial fluids. Environmental durability includes UV ozone weather and abrasion resistance tailored to outdoor marine and coastal conditions.

Elastomeric seal joints provide high movement capability with moderate pressure temperature and chemical exposure making them effective where flexibility and long-term sealing performance are critical.
