Throwaway Holder Assembly

The Throwaway Holder Assembly is a sealed, disposable unit for use in systems where pressures do not exceed 3,000 psig (207 barg). The assembly features a rupture disc sealed between brass fittings. After relieving an overpressure condition, changeout is easily performed by replacing the entire assembly. The Throwaway Assembly can be supplied with a Standard or Composite rupture disc to accomodate various application requirements.

Throwaway units are used on gas bottles, air conditioning systems, refrigeration units, hydraulic accumulators, gas cylinders, portable compressed air systems, and laboratory equipment.

 

Specifications

Maximum Pressure:    3,000 psig (207 barg)
Maximum Temperature:     400°F (204°C)
Materials:        All Brass Components

NOTE: At the factory’s discretion, a fluoropolymer gasket may be added to the assembly.

Features

After the rupture disc is installed in the Throwaway Holder, the inlet and outlet components are permanently affixed to provide a sealed assembly. Each assembly is then inspected by a Beta Backscanner device to verify compliance to the proper rupture disc material thickness. When an overpressure condition occurs, the entire assembly can be quickly removed and replaced with a new assembly.

Options

Two units are available:
    1. A 1,000 psig (68,9 barg) design is compatible with either a Standard or Composite rupture disc, up to a maximum 1,000 psig burst pressure
    2. For higher pressures, a 3,000 psig (207 barg) unit is available. It is compatible with a Standard Rupture Disc

The Throwaway unit, with a 1/2”, 3/4” or 1” Standard or 11/16” Composite Flat Seat (FS) rupture disc, consists of three brass components:
 inlet
 holddown ring
 outlet

The inlet is available in 1/4”, 3/8”, 1/2”, 3/4” or 1” male pipe threads (MPT). The outlet component is available in various configurations to match the requirement of your application.(see Tables 15 & 16)

The maximum temperature limits of the Throwaway Holder are dependent upon the limitations of either the rupture disc or the holder. In the case of the maximum allowable temperature, use the lesser limit of the two.
