Elaflex rubber expansion joints

Elaflex is an internationally recognized manufacturer of high-quality hoses, couplings, rubber expansion joints, and accessories. Elaflex rubber expansion joints (ERV) are specifically designed to compensate for pipeline movements, vibration, and thermal expansion, as well as to dampen noise and pressure surges. The products are manufactured in Germany and comply with the strictest European and international standards.

Applications

Elaflex rubber expansion joints are widely used in the following areas:

• Industrial pipelines (chemicals, hydrogen, water, steam, oil, gas)
• HVAC systems
• Power plants
• Process industry
• Shipbuilding and offshore

Advantages

• High Quality and Safety: All Elaflex rubber expansion joints are manufactured in Germany and are fully traceable. The products comply with PED, MED, ABS, RL, DNV, EN 681-2, DIN 4809, and other industry standards.
• Wide Range of Materials: Expansion joints are available in various rubber compounds (EPDM, NBR, Hypalon, Neoprene, Butyl, Viton, PTFE), suitable for different media and temperature ranges.
• Durability and Long Service Life: The joints are resistant to UV, ozone, and chemicals. Reinforced construction ensures long service life and high pressure resistance.
• Noise and Vibration Damping: Rubber expansion joints effectively dampen pipeline vibration, noise, and pressure surges.

Technical Information

A wide selection of flanges, vacuum rings, PTFE liners, tie rods, joints, vacuum rings, fire protection covers, fittings, and protective equipment enables easy installation and maintenance. Standard expansion joint lengths range from 130 to 200 mm. Sizes available from DN 30 to DN 1000; larger sizes available upon request.

Installation and Use

• Follow the manufacturer’s instructions for design, installation, and use (including maximum pressure, temperature range, and allowable movement).
• Protect expansion joints from mechanical damage and chemical splashes.
• Use only compatible flanges and accessories.
• Regular inspection and maintenance extend service life.
