en.Wedoany.com Reported - Elaflex's ERV series rubber expansion joints play a key role in industrial piping systems by absorbing thermal expansion, reducing vibration and noise. Their products have been applied in various media transport scenarios, from drinking water to liquefied CO₂. The series covers a size range from DN25 to DN1000, providing engineers with a consistent flexible connection solution that can be directly inserted into pipelines as removable pipe sections, simplifying installation, inspection, and maintenance processes.

Each ERV unit features a molded single-sphere rubber bellows combined with a rotating metal flange structure, enabling significant axial, lateral, and angular movement while maintaining low reaction forces and minimal resistance. Mario Iglic, Sales Manager at Elaflex Pacific, told The Australian Pipeliner that since 1956, the company's ERV rubber expansion joints have reliably performed these tasks, with their construction and quality establishing them as an international industry standard.

The product series offers a variety of rubber compounds and flange options, allowing pipeline operators to customize expansion joints based on specific requirements such as media type, temperature, and chemical resistance. The Elaflex website also features an online ERV configurator that can combine different bellows, flanges, and accessories to simulate performance and save parameters. ERV expansion joints are widely used in Australia in power stations, refineries, water treatment facilities, and fluid freight applications.

For larger sizes or customized applications, Elaflex can provide expansion joints manufactured by its group company Ditec. Ditec can produce expansion joints in circular, rectangular, oval, or other shapes, suitable for high-pressure applications up to DN5000. Both ERV and Ditec expansion joints, with their ability to handle extremely low temperatures, are used in carbon capture and storage (CCS) projects worldwide. Ditec products are more suitable for capture facilities, while the ERV series is used for transporting captured CO₂ to trucks and ships, as well as for small-diameter pipelines within facilities.

Durability is one of the core features of the ERV series. The bellows are manufactured by ContiTech exclusively for Elaflex. Iglic stated that these expansion joints have an excellent service life, with a total cost of ownership lower than comparable products on the market, making them a reliable choice for engineers and purchasers considering long-term benefits.
