CorrOcean 2507100-578P-H 4-Element Sand Probe with Hollow Plug

CorrOcean 2507100-578P-H 4-Element Sand Probe With Hollow Plug

The CorrOcean 2507100-578P-H is a 4-element heavy-duty high-precision sand monitoring probe for severe-service marine, offshore and subsea hydrocarbon extraction systems. Applied to the measurement of particulate-induced erosion in production flowlines, Electrical Resistance (ER) technology measures the metal loss of sensor devices due to solid sand impacts.

This arrangement enables for seamless deployment, online monitoring and retrieval at full pipeline operating pressures with an integrated hollow plug assembly when used in conjunction with normal 2 inch mechanical or hydraulic high pressure access systems. The 4-element matrix offers automatic temperature correction and redundant sensor channels for excellent dependability in multi-phase flows with aggressive sand quantities, crude oil, gas and corrosive generated water.

• Alternate Legacy ID: CO-SP-4E-HP-578

Applications

• Offshore Production Platforms: Monitoring sand breakout and velocity-dependent piping erosion in wellheads and production manifolds.
• Subsea Christmas Trees & Flowlines: Early warning detection of abrasive solids production before severe wall thinning occurs in high-velocity bend pipes.
• Refinery & Petrochemical Inlets: Measuring catalyst fines carryover and particulate abrasiveness in heavy crude processing lines.
• Marine Custody Transfer Systems: Tracking sediment and solid concentration limits during bulk oil transfer operations onboard FPSO (Floating Production, Storage, and Offloading) vessels.

Engineer’s Insight:

• Element Positioning & Lifespan Maximization: When installing the 4-element probe into a 90-degree bend or down-stream of a choke valve, ensure the active elements face directly into the geometric center of the fluid flow vector. Incorrect orientation shields the active element, skewing the erosion calculations significantly downward and leading to false-negative sand telemetry readings.
• Hollow Plug Maintenance O-Rings: During routinely scheduled inspection rotations, never reuse elastomeric seals. The high gas-to-oil ratios (GOR) in modern offshore lines subject the hollow plug seals to Explosive Decompression (ED). Always replace the primary O-ring set with high-grade, NORSOK M-710 approved HNBR or FFKM seals to prevent dangerous blowouts during the next insertion cycle.
