What is Rupture Disk?
Overpressure and vacuum is feature of virtually every production process. If the pressure rises above or falls below the specified limits, major damage to plant components may result. The consequences are production standstills and serious commercial losses. A reliable and fast reacting pressure relief system is therefore essential to protect the plant in case the pressure rises above or falls below these limits.

Rupture discs are non-reclosing safety devices with precisely defined breaking points. They usually are full metal elements of nickel, nickel-based materials or stainless steel.to know more read the more details.

What is a rupture disk? 

Overpressure and vacuum is feature of virtually every production process. If the pressure rises above or falls below the specified limits, major damage to plant components may result. The consequences are production standstills and serious commercial losses. that's why a rupture disk has been used.in fact a reliable and fast reacting pressure relief system is therefore essential to protect the plant in case the pressure rises above or falls below these limits. we use rupture disk brust pressure to avoid these damages.

Rupture discs are non-reclosing safety devices with precisely defined breaking points. They usually are full metal elements of nickel, nickel-based materials or stainless steel.

Rupture Disks are essentially used in processes with low to high pressures, high operating temperatures and considerable pressure oscillations. The scoring is located on the atmosphere side of the rupture disc, while the process facing side has a smooth finish so that adherence of the medium is prevented.

Rupture Disk Installation

Rupture disks installation can be  alone or in combination with other types of devices. Once blown, rupture disks do not reseat; thus, the entire contents of the upstream process equipment will be vented. In KARAJET, Our rupture discs are mounted in the holder directly between standard flanges according to EN 1092 or ASME B.16.5

 Rupture discs are used for their superior properties for example in reactors, pressure vessels and gas cylinders either as sole pressure protection or in combination with a safety valve 

Purposes of Rupture Disks

If we want to talk about the Rupture Disk function we could express that If the pressure exceeds the permissible range during the process, the rupture disc ruptures. Thus the pressure can be released immediately 

Rupture Disk Holder

The holder Assembly is available in nominal sizes ranging from 1″ through 36″ for installation between ASME class companion flanges. Standard materials for the holder include 316 stainless steel, carbon steel, Alloy 400 and Alloy C276.

The flexibility of our holder assembly enables employment of various rupture disc types and burst pressures. Thus, the type of rupture disc can be changed rather than substituting the entire holder.

PRIMARY RELIEF


If used for primary relief, the rupture disk is the only device utilized for pressure relief. As such, it has the advantages of being leak tight, an instantaneous response time, minimum pressure drop, lowest cost, very high re-liability, and minimum maintenance. It has the disadvantage that it must be replaced after each rupture occurrence, and allows venting until system pressure equals downstream pressure.

 

SECONDARY RELIEF


When used in a secondary relief capacity, the rupture disk provides a backup vent to a primary relief device, usually a Relief valve. Its purpose here is usually to provide additional protection against an unlikely but possible major event that would exceed the capacity .of the primary relief device
