Industrial Safety Solutions for Oil & Gas

Safety is of primary concern in Oil & Gas Industries as many of the liquids and gasses extracted and refined are volatile, hazardous and stored under pressure. Overpressure protection of well casings, drilling tools and equipment is essential to provide safe operating conditions for plant personnel as well as preventive maintenance for drilling rigs and equipment. Over-pressurization of oil and gas containment vessels, as well as fluid transfer piping is a potential condition that can result in catastrophic results to the process, the environment, and plant personnel.


Elva and Zook recognizes that upstream applications have a significant degree of complexity. Our engineering experts have solved many customer applications by designing the right solution. In drilling applications, Elva offers rupture disk devices for both pressure activation and pressure relief including:

  • Overpressure protection within the casing, drill string or downhole tool
  • Pressure activation of equipment or tools
  • Hydraulic fracking
  • Over-pressure protection of liquid/gas separators
  • Perforation guns
  • Testing of the tubing string
  • Pressure vessels ie. towers, knock-out, drums, heat exchangers, separators, accumulators, flare stacks, sulfur recovery units, etc.
  • Downhole applications with customized backpressure support
  • Wellhead protection
  • Cementing Pumps


When intermodal tanks are used ZOOK’s ICP series rupture disks are the ideal solution. For this application, ZOOK’s TD rupture disk is recommended to protect the tank trailer. Other transportation methods might include barge or rail.


Rupture disks are another common component found in midstream operations.

Compressor / Pump Stations

Rupture disks are required near the pump to prevent an over-pressure in the event of a blockage in the line. They can also be utilized to drastically reduce fugitive emissions from the compressor/pump.


The final stage in the production process is downstream, where the oil and natural gas are processed and refined into usable products. Elva offers a complete solution for all downstream production processes. In refineries and petrochemical plants, a variety of pressure relief devices are required including:

  • Towers
  • Knock out drums
  • Heat exchangers
  • Separators
  • Accumulators
  • Flare stacks
  • Sulphur recovery units
  • Pressure relief valves
  • Storage tanks/batteries

Pressure Relief Valve Isolation

The primary reasons for applying rupture disks downstream of pressure relief valves are:

  • Prevent corrosion of relief valve
  • Reduce cost of relief valve by negating costly special alloy trim/internals
  • Prevent fouling or sticking of the relief valve
  • Prevent variable superimposed backpressure from affecting relief valve
  • Detect opening or leakage of relief valve
  • Elimination SRV emissions -valve isolation


Storage is another component of downstream operations. Rupture disks are utilized on the storage tanks.


Fire situation causes serious irreversible damage in Oil & Gas plants. In these plants where flammable materials are highly appearing, the fire situation should be detected with automatic fire detection system and should be extinguished with automatic fire suppression systems.
