Rupture discs

Producer: FDC

A rupture disc is a safety diaphragm device that ruptures when the system is over-pressurised beyond critical pressure. By rupturing, the disc relieves pressure, which ultimately helps protect equipment and human life.

The rupture disc consists of a special material, has a special shape, and has no size limitations. The rupture disc has a wide range of applications, is easy to install and adjust, and the demand for this product is constantly increasing as the cost reduction effect of its use is obvious. In addition, the rupture disc is a thermal protection against high and low temperatures, specially designed to increase the durability of equipment.

Description

Rupture discs are used when pressure rises rapidly and uncontrollably, when leaks are unacceptable, when there is loss of equipment performance due to disturbing foreign matter, and under unfavourable conditions such as caustic or corrosive fluid, high and low temperatures. The rupture disc is installed on a variety of pressure vessels, pipelines, heat exchangers and furnaces in industrial plants to ensure site safety.

The main purpose of rupture discs is to ensure system safety by controlling pressure. If the set pressure limits are exceeded, the rupture disc automatically ruptures, allowing the excess pressure to be vented and preventing possible emergencies. This is particularly important in production environments where system pressures can vary and are subject to risks of overpressurisation.

The rupture disc holder locks the rupture disc in position and ensures its reliable operation.

FDC rupture discs prevent even 1% of accidents from occurring. FDC Company Limited and the ATEX CENTER explosion protection centre of expertise are your partners in industrial safety.

Disc types

FDC rupture discs are divided into different types depending on the type of rupture and technical characteristics.

  • The first type is the reversible (or reverse) type
  • It is effectively utilised under counter pressure as well as vibration and pulsation conditions.

    1. KSRBK is a specialised and patented FDC product consisting of a control disc and a sealing disc. Its parameters are easy to control and the burst pressure is accurate. This type of disc can be used in a wide range of pressure temperatures and fluid types.

    2. KSRRK has a sliding type design that is broken by a knife ring attached to the disc when the dome is rotated. The disc and knife are assembled as a single unit. This allows it to effectively resist vibrations and impulses as well as counter pressure.

    • Notched dome discs
    • KSRSF has a forward curved dome design with precisely manufactured notches that fracture under stress. This type of disc is mainly used for high pressure applications.

      • Discs with composite dome type
      • The discs are a composite dome that breaks due to a precisely manufactured cut on the top surface of the disc. It is applicable for any medium: liquid, vapour, gas and others. Since the use of Teflon as the material of this type of sealing disc gives poor resistance to high temperature, in order to make the product applicable at high temperatures, a metal seal or temperature protection device is used in this case.

        • Composite flat disc type
        • KSRO has a complex and flat structure, which is broken by a sliding part, is mounted on the upper surface of the disc and can be used by mounting on a flange without a separate holder.

Installation

The installation of the rupture disc is very simple. The rupture disc consists of a disc and a holder and is installed by inserting the disc between the top and bottom of this holder.

Secure the flange bolts and nuts by tightening them symmetrically in the order shown in the video.

When the pressure exceeds the required values, аn accident can occur at any time. If the pressure exceeds the set point, the rupture disc ruptures to relieve the pressure built up inside the unit and protect the equipment.

Each rupture disc is a disposable product and must be replaced after rupture.
