Product covers both positive and negative pressure relief
Elfab has developed a two-way rupture disc to prevent vessel damage under vacuum or from overpressure.
Customers who previously relied on separate rupture discs for positive and negative pressure relief can now use this disc alone to fulfil the same protective function via a single installation point. This allows customers to safeguard their application while significantly reducing costs.
Available in non-fragmenting composite or graphite designs, and compatible with liquid, gas and vapour, the two-way disc is suitable for most customer applications. Both disc designs feature Elfab’s unique non-invasive, ATEX-approved detection system, Flo-Tel™, making them the only bidirectional discs on the market to benefit from reusable burst detection. Instant burst indication is critical to many process applications while the detection system’s reusable nature enables customers to make further cost savings.
The composite design is supplied in stainless steel as standard but a wide range of other materials can also be provided. The graphite disc is non-torque sensitive and needs no holder, instead fitting directly between flanges. Both can be installed between a variety of flange arrangements, depending on specific application requirements.
