3 New Cosasco Sensors Detect CUI

Corrosion technology supplier Rohrback Cosasco has introduced three new Cosasco CUI Corrosion Sensors for detecting corrosion under insulation.

All three models are designed to offer reliable, low-cost, simple installation; direct corrosion detection; and a lower cost per monitoring point than currently available.

 Cosasco has three models of its new sensor.
Cosasco has three models of the new sensor (from left): Continuous Insulated Braid “Corrosion Fuse” Wire (Type 1), Inserted “Corrosion Fuse” Probe Array (Type 2), and CUI Corrosometer Probe (Type 3).

The CUI sensors can be customized to meet individual requirements and applications to fit with any plant integrity management program, the manufacturer reports. The models are:

Corrosion Fuse Wire Sensor (Type 1)

The Insulated Braid Wire Sensor (patent pending) is designed to detect corrosion that has occurred over a relatively large area.

The sensor can use either a single insulated carbon steel wire of a certain element thickness, or multiple wires of varying thickness.

The single wire can be used as a “corrosion fuse” to indicate that an amount of corrosion has occurred; multiple wires can be used as step measurements, indicating the rate at which corrosion is occurring. (The latter method is best used as a part of a preventive maintenance program.)

If installed under a tape coating, the sensor can help determine the coating’s integrity and the corrosion on the pipe surface that may occur due to the coating breakdown.

Corrosion Fuse Inserted Probe Array Sensor (Type 2)

The Inserted Probe Array Sensor acts as a “corrosion fuse” detector that indicates corrosion occurring at known discrete locations on the pipe surface. It was originally designed to be installed during the remediation and mitigation of corrosion damage under thermally insulated pipeline field joints.

The four-probe sensor array has two “corrosion fuse” elements per probe. It can be applied on new pipelines, field joints and insulated process lines; installed on existing insulated pipe; or used as part of a repair.

Corrosometer Probe (Type 3)

An adaptation of the Type 2 ‘Corrosion Fuse’ sensor, the CUI Corrosometer Probe Sensor is an individual electrical resistance (ER) probe that provides a measurement of the corrosion rate near the pipe surface.

It is useful in determining the underlying cause of corrosion and the ability to measure changes in corrosion conditions, such as the effectiveness of repairs, temperature cycles or environmental changes.

Remote interrogation via extension cable up to 150 feet (50m) is possible.

Sensor Types 2 and 3 do not require removal of insulation.

Based in Santa Fe Springs, CA, Rohrback Cosasco Systems (RCS) has been a global provider of corrosion monitoring technology and services since 1950.
