Two-way rupture disc
Published: 25 February, 2014
Pressure management specialist 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 can allow 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 said to be suitable for most customer applications. Elfab says both disc designs feature its unique non-invasive, ATEX-approved detection system, Flo-Tel, making them the only bidirectional discs on the market to benefit from reusable burst
