Process equipment protection

Rupture discs and pressure relief

Supply of rupture discs, holders and relief assemblies for pressure vessels, piping and process equipment. Selection follows the actual fluid, operating conditions and arrangements for handling the released medium.

Operating context

The whole application matters.

A rupture disc opens a relief path under specified conditions and is replaced after activation. The range includes conventional domed, flat and reverse buckling discs, designs with defined opening lines and graphite versions. A suitable holder, connection and interface with the protected equipment form part of the solution. Pressure cycling, vacuum, backpressure and corrosion also influence the choice.

Scope of the solution

  • Conventional domed, flat and reverse buckling rupture discs with corresponding holders.
  • Graphite and other material options selected for chemical and thermal conditions.
  • Round or rectangular relief elements for individually assessed bulk solids applications.
  • Replacement discs and interfaces with safety valves and relief piping.

Engineering priorities

From operating need to design.

01

Operating conditions and activation

The nominal disc rating alone is insufficient. Selection considers temperature at activation, normal pressure fluctuations and the margin between operating conditions and the required response. Mixtures require information about phase and possible composition changes.

02

Disc, holder and discharge path

The disc and holder form a matched assembly. Geometry, orientation, materials, seals and opening clearance need review. The design also considers backpressure, downstream piping and arrangements for routing the released medium.

03

Standalone protection or a valve assembly

Suitable designs can isolate a safety valve from process fluid. The complete assembly needs assessment, including the space between the disc and valve, its monitoring and its effect on relief performance. Components are not interchangeable by default.

Before engineering

Inputs that matter.

  • Fluid, phase, composition, and normal and abnormal pressure and temperature conditions.
  • Required activation conditions, cycling, vacuum, backpressure and relief scenario data.
  • Connection dimensions, existing assembly details, material requirements and discharge arrangements.

Agreed with the proposal

Outputs and acceptance.

  • Technical specification of the disc, holder and connection for agreed conditions.
  • Installation, identification and replacement information for supplied components.
  • An interface schedule and the information needed to verify the complete protective function.

The actual scope and acceptance criteria depend on the application and contract.

Before we start

Questions that shape the project.

Can one disc be used with different fluids?

Only after checking the application. Fluid phase, chemical compatibility, temperature and possible fragmentation all affect selection.

What is needed to order a replacement?

Identification of the original disc and holder, activation conditions and confirmation of current operating conditions. Nominal size alone does not establish compatibility.
