Corrosion monitoring probes & systems

Cosasco - USA & UK
ICMS3™ integrated systems
Cosasco - USA & UK
The ECM™ is a multiparameter monitoring system providing surveillance of the environment and quick detection of any deterioration that could result in damage to expensive equipment and valuable assets, like DCS, Computers, etc. Early detection of humid, high temperature, or corrosive conditions will permit corrective action to be taken before substantial damage occurs to, DCS, instrumentation systems or electrical equipment.

The system measures humidity, temperature, and the corrosive attack on two replaceable thin-film sensors. The corrosion rate is shown by indicator lights that correspond to the ISA classification of environments (G1 through GX) for copper and silver.

The DCMS™ tool is another RCS innovation, and the only tool available which provides recorded corrosion and temperature data for the hostile conditions of downhole operation.

The DCMS™ tool may be attached to a variety of wireline approved running tools for insertion into the production well at the start of testing and retrieval from the well at the end of the testing period. The DCMS™ tool can be set at any required depth — wherever the most critical corrosion regions are located. Several DCMS™ tools may be run simultaneously in a well, in order to obtain corrosion data for the different depths, while under the same operating conditions.
Cosasco - USA & UK
The Microcor® corrosion monitoring technology has been developed to substantially increase the speed of response over conventional corrosion monitoring techniques, such as coupons, electrical resistance (ER) probes, and linear polarization resistance (LPR), and is functional in all environments. Microcor® high speed corrosion monitoring is the result of patented technology which combines the rapid response of LPR and the universal applicability of ER. The figure below compares the real world response of various internal corrosion monitoring methods to the Microcor® system. Corrosion rate on a logarithmic scale is plotted against time, also on a logarithmic scale. At 10 mpy, the common W40 electrical resistance probe takes nearly 3 days to show a clear response. A Microcor® internal corrosion monitoring probe with the same useful probe life will show a clear response in 1 hour, and the trend is visible in 15 minutes. Even an LPR corrosion monitoring probe in water will take 5 to 10 minutes to produce a steady corrosion rate reading. This means that the Microcor® corrosion monitoring system is 50 to 100 times more sensitive and faster in response than ER systems. The absolute resolution of the Microcor® electronics is 256 times more sensitive than ER system electronics.
Conventional ER Corrosion Probes
Cosasco - USA & UK
The industry standard for ER (Electrical Resistance) corrosion probes in retrievable, retractable, fixed and flanged mounting that are rated for up to 6,000 psi (41 Mpa) and 850º F (454º C). Cosasco provides a range of measuring instruments that span from simple portables to continuous on-line or data logging instruments to large scale systems that integrate process parameters and corrosion information to optimize control strategies.

Active & passive ultrasonic intelligent sensors

Ultrasonic Intelligent Sensors - topside

DSP Pig Detector - Topside
ClampOn - Norway
The ClampOn DSP PIG Detector, based on our Ultrasonic Intelligent Sensor Technology, represents the latest state-of-the-art technology. This acoustic instrument accurately detects the passage of all types of PIGs in real time, giving instant warning to the operator. Its signal output can also be used to indicate the amount of debris pushed ahead by the PIG during pipeline cleaning operations. ClampOn PIG detection systems have been successfully tested and used by a large number of clients for many years, and this latest model makes the system even more compact and reliable. DSP (Digital Signal Processing) represents leading-edge technology in this field and keeps us ahead of the competition.
DSP Leak Monitor - Topside
ClampOn - Norway
The theory is that a leak creates a very high-frequency noise that can be monitored by an ultrasonic sensor. In a «non-leak» situation the ultrasonic pattern will be constant, but when a leak occurs the signature will change dramatically. ClampOn’s DSP technology distinguishes and filters background noise unrelated to leakages so that the hiss from the leaks can warn the operator.

The ClampOn DSP Leak Monitor topside version is designed to be installed at critical points such as valves, flanges, joints, etc., and can monitor very small leakages. A pressure differential of as little as 1 bar can be monitored in gases, and 3 bar in liquids.
CEM - Topside
ClampOn - Norway
The working principle of the ClampOn CEM (Corrosion Erosion Monitor) is based on transmitting ultrasonic signals that propagate through the pipe-wall. The dispersive characteristics of a group of guided acoustic waves, called Lamb modes, are exploited to indicate a mean change in wall thickness relative to reference values acquired during the installation of the CEM system.

The permanently installed CEM system ensures that measurements are repeated frequently and in exactly the same manner, thereby eliminating the weaknesses of manual ultrasonic thickness gauging. Wall thickness trends are generated automatically and can be observed in real time.

Min Pipe diameter: OD 75mm (3”)
Pipe-wall thickness: 4 to 35mm (0,157 to 1,378″)
Distance between transceivers: 0.15m to 2m

Sensitivity: 1% of wall thickness. The presence of liquid in the pipe does not affect sensitivity.

Ultrasonic Intelligent Sensors - subsea

CEM - Subsea
ClampOn - Norway

The ClampOn Subsea CEM measures and monitors wall thickness loss in pipes, vessels or other metal structures. The instrument uses Acoustic Guided Lamb Waves (AGLW), with the result output of the average wall thickness reading for a large section of pipe. Transducer pairs operate in a pitch-catch mode and use the ultrasonic waves to give the average wall thickness between the transducer pairs. The transducers are fixed at pre-determined points on the pipe to monitor the wall thickness loss in sections of the pipe up to two meters long.

The subsea CEM can utilize up to 32 transducers, increasing distance to a maximum of 8 meters. Wall thickness trends are generated automatically and can be observed in real-time on a computer running ClampOn CEM software, or logged internally in a data logger.

Design depth is 3000m.

ClampOn - Norway
ClampOn’s Subsea (Max Operational Depth 2700m) WTM is a flexible tool designed for temporary installation and inspection at multiple locations. The instrument measures pipe wall thickness using the travel time of ultrasonic pulses. It is equipped with a piezo-electric element to provide precise wall thickness measurements in multi echo mode. The WTM is non-intrusive and can take measurements on coated pipes.

Data is stored in flash memory for fast and simple download and data analysis once retrieved, or be available as real-time measurement through an optional subsea cable-to-surface capability.

Special Very Critical Service Isolating products

Isolating Kits and gaskets for severe services and very high pressure applications

Pikotek® VCS/VCFS™
The Pikotek® VCS™ isolating gasket provides exceptional isolating and sealing performances in aggressive material application, thanks to its PTFE spring-energized face seal, seated in an insulating laminate and permanently bonded to a high-strength stainless steel core (other materials available by request)

It can be used at all pressures up through ANSI 2500# and API 10,000#. VCS™ gasket is precisely sized to the bore to protect flange faces and prevents turbulent flow at flanged connections to mitigate media-induced corrosion and flow-induced erosion. Due to its unique pressure activated sealing mechanism, the gasket requires far less bolt stress to seal than any other gasket. Available as a stand-alone product or as an Isolating Kit (complete with isolating washers and sleeves).

Temperature ranges: with G10 Gasket material, up to 130 °C and with G11 gasket material up to 200 °C.

The VCFS™ adds fire service capability to the standard Pikotek® VCS design through the use of a secondary sealing element that is capable of maintaining a seal while subject to a 1500°F (815°C) fire. The VCFS fire resistant gasket combines proven sealing performance in aggressive environments with the capability to pass the API 6FB, 3rd Edition fire test.
Pikotek® VCS-ID™
Pikotek® VCS-ID™
The VCS-ID (Inside Diameter) Seal introduces an internal, machined PTFE seal at the bore of the existing VCS design platform. The use of a patented interlocking mechanism ensures an extremely tight seal at the bore and resistance to effects from internal pressure or aggressive media. The interlocking mechanism is intentionally designed to be approximately .100” larger than the pipe ID.
Pikotek® VCXT™
The GPT VCXT™ flange isolating kit is comprised of an isolating gasket, isolating sleeves, isolating washers and metal backing washers. The isolating gasket is constructed from a machined metal core utilizing a serrated profile. The metal core is faced with THERMa-PUR™, a proprietary high temperature sealing material. Correct gasket location is ensured by the use of a Garlock 5500 spacer ring, located around the outer edge of the serrated metal core. Available in pressure classs up to ANSI 2500#. Operational temperature range: » -200 ̊C to 410 ̊C
GPT-Evolution Isolation Gaskets
EVOLUTION® Isolation Gasket - The Future of Flange Isolation. Available Now!
EVOLUTION® is a patent pending product that is the first of its kind to be a fully encapsulated isolating gasket. The thinner, 1/8” (3mm) design minimizes the difficulties often encountered while attempting to install thicker isolating gaskets. The total encapsulation allows the gasket to be hydro-tested and kept in the pipeline with virtually no loss in isolation properties.

This innovative gasket is coated using a GPT proprietary material designed specifically for the oil and gas industry that is extremely abrasion and impact resistant. The coating is also chemically resistant to attack from H₂S, steam, CO, CO₂, and other chemicals found in oil and gas pipelines.

EVOLUTION® has passed API 6FB fire testing in multiple sizes and pressure classes and has a considerable increase in operating temperature over GRE products. Furthermore, EVOLUTION® does not have the permeation issues or chemical attack that plagues GRE gaskets.

Under harsh conditions, gaskets made from GRE may be vulnerable to chemical attack, blowout, thermal attack, hydrolysis and emissions —all of which can have serious consequences. EVOLUTION® is different. Its revolutionary materials and design provides industry-leading resistance to leakage and flange corrosion, as well as unprecedented levels of fire safety.

Unlike GRE gaskets, which are prone to delamination, EVOLUTION® has no laminations and as a result can better withstand high-pressure environments.

Rated to 500°F (260°C)*, EVOLUTION® can also operate under high temperatures. Tested comprehensively for safety, the product has API 6FB, 3rd Edition Fire Test recognition.

Isolating kits & gaskets for pressure classes 150 & 300

LineBacker®  sealing gaskets use a rectangular sealing element, referred to as a "quad" ring, in combination with a unique groove design to effectively seal and isolate flanges of all types. Its unique quad ring design is providing elastic memory for elastomers not normally associated with this characteristic. 
Materials such as PTFE, used as sealing elements, may dramatically increase the ability to match gasket materials to service conditions. This greater variety of materials also provides excellent temperature and chemical range compatibility. LineBacker® sealing gaskets are self-energizing with theoretical near-zero "m" and "y" factors resulting in a positive seal without excessive bolt loads - as are often required with flat gaskets.
Pikotek® PGE™
The Pikotek® PGE™ is a low-pressure service isolation kit designed for electrical flange isolation and/or general sealing applications
The PGE™ was designed to give operators an alternative to the failure prone phenolic-based isolating gaskets. The unique design of the PGE™ system incorporates patented overlapping and offsetting seal grooves. The purpose of this design is to break each layer of laminate within the gasket itself, thereby creating a barrier through which fluid and/or gas cannot migrate. The sealing element can be any elastomeric material, as well as more sophisticated spring-energized PTFE lip seals. As a result of this advanced seal design, maintenance-free flange isolation and flange face corrosion mitigation are achieved economically. Depending upon the sealing element selected, the PGE™ is rated for most hydrocarbon and water service applications.

This gasket is suitable for use in raised-face and flat-face flanges in ANSI Class 150, 300 and 600 service (or equivalent). In addition to providing electrical isolation, the gasket is excellent for isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired.
