Abstract: A vortex suppressing sample probe for a fluid flowing along a pathway. The sample probe includes an elongate body with an outer surface having an elongate leading section and an elongate trailing section along the length of the elongate body, in relation to a direction of fluid flow when the device is located in the pathway. The elongate body can have at least one channel or groove which extends from the elongate leading section to the elongate trailing section of the elongate body. The channel or groove can be configured so that in use, when the device is in the pathway, the channel or groove allows fluid flow towards the trailing section that disrupts the formation of vortices. The groove can be a circumferential groove that follows a sinusoidal path around the outer surface of the elongate body.

Abstract: A device for measuring a conduit arranged in a submerged or subterraneous environment and surrounded by an insulator layer. The device includes a first electrode; a mounting unit to be arranged on a surface of the conduit to create an enclosure against the surface, the enclosure containing the first electrode and configured to form a dielectric between the first electrode and the environment. A second electrode is configured to be arranged at a distance of the surface and at a distance of the first electrode and is intended to be in contact with the environment. A measurement instrument is configured to determine a value which is representative of an impedance between the first electrode and the second electrode.

Abstract: This disclosure relates to the monitoring and detection of corrosion and/or erosion of pipes, vessels, and other components in an industrial facility. The monitoring system may comprise of an arrangement of guided wave (GW) transducers and a longitudinal wave (LW) transducer affixed to the piping component to collectively measure for localized corrosion of the piping component without necessarily requiring a thickness map. The monitoring system may use an intelligent amplified multiplexer/switch to control the operation of the transducers that may be controlled and operated to generate waves in the kilohertz range and megahertz range with the same hardware.

Abstract: A vortex suppression device (10) for a fluid flowing along a pathway (A-E), including: an elongate body with an outer surface having an elongate leading section and an elongate trailing section along the length of the elongate body, in relation to a direction of fluid flow (A-E) when the device is located in the pathway, the elongate body having at least one channel (24a-24d, 26a, 26b) which extends from the elongate leading section to the elongate trailing section of the elongate body, the channel (24a-24d, 26a, 26b) being configured so that in use, when the device is in the pathway, the channel (24a-24d, 26a, 26b) allows fluid flow (J) towards the trailing section that disrupts the formation of vortices (D).

Abstract: Assemblies and methods for maintaining cathodic monitoring of underground structures may include an electrode watering assembly having a cap that includes a cap body of a rigid material defining one or more chambers adjacent to a proximal electrode end of a permanent reference electrode when installed thereon. The cap body may include a distal cap end defining a distal opening configured to be disposed around the proximal electrode end and a proximal cap end defining a proximal opening. The electrode watering assembly may include a conduit having a flexible material. The conduit may include a distal conduit end configured to be fluidly coupled to the proximal opening and a proximal conduit end configured to be positioned at a cathodic test station, such that fluid directed into the proximal conduit end is directed through the conduit and into the one or more chambers for watering at least the proximal electrode end.

Abstract: An apparatus for in-situ monitoring and measuring of general corrosion and localized microbiologically influenced corrosion (MIC) in a simulated environment is provided. The apparatus includes a chamber containing an electrolyte solution and a microbe specimen. The chamber includes a pair of electrical resistance (ER) probes that measure a current flowing through the electrolyte solution and a general corrosion rate on the surface of the ER probes. The chamber also includes a pair of electrochemical noise (EN) probes. The EN probes are aligned to face one another such that the EN probes measure a localized corrosion rate on the surface of the EN probes and measure the influence of gravity on MIC. The apparatus measures the general and localized corrosion rates simultaneously without polarizing the surface of the ER and EN probes.

Abstract: Methods for determining the internal corrosion rate of steel pipelines. During the methods the calibration constant is determined under laboratory conditions then by using the calibration constant field conditions are modeled under laboratory conditions and the corrosion rate is determined, then in the same manner as under laboratory conditions the corrosion rate is determined under field conditions. Further, the invention is a measuring arrangement for determining the calibration constant and the corrosion rate for the internal corrosion rate of steel pipelines (1) the arrangement is applicable to carry out the methods under laboratory and field conditions. The arrangement consists of a polarizing and measuring unit (5) having a two-channel power output (2), a potential-measuring input (3), and a ground connection (4), a control and data storage unit (6), and three probes (8) with counter-electrodes (7). At least one probe (8) is also provided with a reference electrode (9).

Abstract: A method to determine vapor phase corrosion load in paper and board manufacturing system is disclosed. The method allows optimizing oxidative biocide content in aqueous solutions, suspensions and slurries in the paper and board manufacturing system. The method is based on determination of redox values (rH) of the system during determined time period. A correlation between rH values exceeding a predetermined rH threshold values and corrosion load provides an estimate of increased or decreased corrosion load and allows timely changes to biocide dosage.
