In-line Rupture Disc Sub


In-line Rupture Disc Sub

The WellEnTech In-line Rupture Disc Sub provides a means of communicating with the tubing below the sub. Ideally suited for operations where the internals of the tubing string needs to be isolated from well fluids such as acid injection applications or reverse circulation. The tool can be supplied with a range of calibrated Rupture discs which provide a choice of activation pressures to suit operational requirements.


  • One piece design
  • No specialist assembly tools required
  • Fully adjustable activation pressure
  • Easily redressed
  • Debris circulation
  • Reverse circulation applications
  • Well Stimulation operations
  • Any flow dependent well operations

The WellEnTech Rupture Disc Sub is configured at surface. Burst discs are easily assembled and removed using a standard Allen key. A burst disc is inserted into the tool which is rated at a pressure value in excess of pressures anticipated during well operations. If however, when required, the Rupture Disc Sub enables the operator to apply a predetermined pressure and rupture the disc, thereby opening up a communication path through the tubing string.
