Insert pipe expansion joints between sections of pipe in your system to reduce stress on pipes and lengthen the life of your system. They have a flexible center section that keeps the pipe connected when there is movement or misalignment between pipes, and they also absorb noise and vibration in the line from pumps and other machinery.
Choose from single-sphere expansion and double-sphere expansion joints. Single-sphere are the most common type of expansion joint and are typically used to absorb axial movements such as compression and expansion. Double-sphere expansion joints can compensate for axial, lateral, and angular movements in a pipe system, such as those caused by earthquakes, foundation settling, or temperature changes.
EPDM (ethylene propylene diene monomer) rubber is resistant to damage from water, abrasion, weather, and ozone, making EPDM pipe expansion joints well suited for use in outdoor applications and HVAC, industrial piping, water, and waste water systems.
With good resistance to sunlight, fuels, ozone, and oxidation, neoprene is a versatile rubber-like material that remains flexible over a wide temperature range and is suitable for outdoor use. Use these expansion joints in HVAC, petrochemical, industrial piping, waste water, and pollution control applications.
PTFE (polytetrafluoroethylene) resists damage when exposed to high temperatures and chemicals, making PTFE expansion joints a good choice for applications in tough environments such as chemical plants and water plants.
