EuropCorr Sacrificial Sand Probe, Sand Plug Configuration

Erosion-corrosion occurs in flowing fluids carrying sand, silt, precipitated salts or other solids, which thin or remove the protective layer and greatly increase metal loss. EuropCorr sand probes are a simple and robust way to detect significant erosion in high-velocity flow lines.

The sensing part of the sacrificial sand probe is a thin-wall steel tube (generally 1 mm) inserted into the flow line. When sand or solids have eroded through the tube, line pressure reaches a sensing device (pressure gauge, or pneumatic or electric sensor connected to the control room), giving early warning of critical metal loss.

In this configuration the Sand Plug assembly contains a pin acting as a needle valve to isolate the pressure once the tube is eroded. It is used with the 2" high-pressure mechanical access system and the probe can be changed or inspected with the Retrieval Tool Kit without interrupting the system. The general assembly comprises the access fitting, sand plug, sand probe, cover with hole, bleed valve and pressure gauge or alarm.
