Flat Composite (DSC-FCD)
Economic solution for very low pressure applications
Flat Composite is a tension-loaded forward acting rupture disc of composite design with a unique tri-membrane construction. The Flat Composite (FCD) rupture disc offers the widest size range of any product type and acts as a reliable solution across a wide variety of process conditions especially where there is a requirement for very low burst pressures.
Widest size range for low pressures
The Flat composite design has the widest size range of any product type Elfab offer, ranging from 25mm to 800mm. Its tri-membrane construction comprises a sealing membrane with a choice of metals ranging from Stainless Steel as standard to hastelloy, Nickel, Inconel or Monel to best suit the process conditions. The Flat Composite is designed for use with Elfab’s standard forward acting rupture disc holder, also available in a wide range of corrosive resistant materials. Further benefiting from a /- 5% tolerance with a wide temperature compatibility, Flat Composites are a cost effective solution for many process conditions.
Non-fragmenting composite disc design
This non-fragmenting rupture disc design, provides enriched protection, reliability and accurate burst control to various applications. The Flat Composite is manufactured with various slotting arrangements to meet customers’ specific application requirements. Compatible with liquid, gas or vapour mediums the Flat Composite can withstand vacuum or back pressures when fitted with a vacuum support making this composite design suitable for a range of process conditions.
Cutting costs on rewiring
Flat Composite is fitted with Flo-Tel actuator as standard, and installed into Elfab’s forward-acting rupture disc holder. The flat bursting disc design is used for achieving very low burst pressures, and with Elfab’s unique, reusable, non-invasive burst detection system Flo-Tel™ , the customer will benefit from reliable burst detection in environments where other detectors may not accurately function as well as significant cost savings.
Leading the industry in advanced quality performance Elfab pride themselves in offering the highest level of quality and are accredited to a number of leading industry standards. Elfab’s rupture discs can be manufactured to ISO 4126 or ASME VIII dependent on customers’ requirements.
When used in combination Elfab’s rupture discs and detection systems can offer industry leading SIL ratings to offer customers increased safety information. Please contact our technically trained sales engineers for more information.
