  • Patent number: 10947818
    Abstract: A detection system for use with a pipeline network having a fluid flowing therethrough. The fluid contains an ingredient that deposits on the interior walls of the pipeline network. The detection system is interposed within the pipeline network and comprises a first fluid path and a second fluid path. A material is distributed throughout the interior of the second fluid path that is capable of inducing and accelerating the deposition of the fluid ingredient on the walls of the second fluid path. A sensor exposed to the second fluid path monitors changes in the path indicative of deposit build-up. The sensor communicates with a control system. The control system directs a chemical injector to introduce chemical inhibitors into the pipeline network to inhibit ingredient deposition on the walls of the pipeline network.

    Abstract: A system for measuring corrosion and corrosion-erosion rates in a high temperature, high pressure multiphase dynamic environment includes a plurality of ring-shaped test coupons disposed within a test vessel in a vertical arrangement relative to one another. A test fluid mixture is added to the vessel and the temperature and pressure are maintained such that the mixture exists in a multiphase condition that has a vertical stratification such that each test coupon is exposed to a different phase and/or combination of phases of the fluid. Impellers can be used to stir the fluid to provide a dynamic environment. The fluid can include particulate matter to simulate real world test conditions. Separator plates can be disposed at different vertical locations within the vessel to maintain separation between various phases of the fluids and further restrict particulate matter from migrating between sections of the test system.

  • Patent number: 10513922
    Abstract: Methods and systems for monitoring material loss in a downhole environment arising from corrosion and/or erosion include placing a downhole sensor in a borehole. The resistance of the downhole sensor is measured using a four-probe resistance technique in which a power source is provided at two electrodes of the downhole sensor and voltage is measured at two voltage taps. A rise in voltage over time indicates loss of conductive material on the downhole sensor. The conductive material on the downhole sensor may be formed to provide discrete voltage increases for improving reliability of material loss and/or rate of material loss resistance measurements.

The resistance of each sensor of the first type tends to increase, and the resistance of each sensor of the second type tends to decrease if the sensor is exposed to an aggressive environment. The circuit board also hosts a control circuit that operates to monitor respective resistances of the various resistance sensors and to process the digital values representing the resistances to estimate the working condition of one or more other electrical circuits located on the circuit board and/or in relatively close proximity to the circuit board in the corresponding equipment cabinet. The control circuit further operates to transmit out an appropriate alarm message if the estimated working condition is deemed unsatisfactory.

A test is performed in a controlled environment, such as an aerosol chamber, using a specific set of test parameters representative of actual use of tested materials, such as dispensing parameters and exposure parameters. During the test, a test surface of the sample is exposed to an aerosol mist. Other surfaces may be protected. After exposure to the aerosol mist, the sample may be allowed to sit for a period of time. The sample is later cleaned and tested to determine effects of various materials in the mist on the sample. In some embodiments, some or all operations may be repeated for the same sample or different samples. The test parameters may be varied to determine compatibility limits.

  • Patent number: 9322142
    Abstract: A field testing device usable to determine the scour-depth potential of soils relied upon to support structural foundations placed in flowing water is disclosed. The device measures the scour potential in-situ, in relative terms, to the scour potential of fine sand using a columnar containment vessel driven into the soil to be tested. Within the columnar containment vessel is a cutting head as an aid in directing a water flow in a generally horizontal direction across the surface of the soil to be tested. Additionally, the cutting head serves to aid in the evacuation of eroded soil from with the containment vessel through an exhaust port. The exhaust port is part of a continuous closed loop water system which provides water for the scour testing and then removes the used water along with eroded soil particulates.

    Abstract: A wear-indicating system includes a wear-indicating mark applied to a portion of a surface edge margin of an internal component of a turbine. The wear-indicating mark is visually discernible from the surface edge margin through boroscopic inspection. An inner extent of the wear-indicating mark is spaced a pre-selected distance from the surface edge.

  • Patent number: 8261601
    Abstract: The described invention relates to a method for determining corrosion in wet gas pipelines comprising: a) using a portion of the liquid phase from a wet gas pipeline; b) placing said portion in a high pressure, high temperature autoclave to prepare a saturated vapor phase; c) transferring the saturated vapor to a corrosion test unit, said unit having a specimen holder section having external, temperature adjustable means, and specimens being arranged in one or more positions within the specimen holder; d) chilling said specimen holder section so as to cause condensation onto said corrosion testing specimens; and, e) calculating a value selected from the group consisting of corrosions rate, pitting of the specimen, weight loss of the specimen, and any combination thereof. The invention process can be practiced in a separate laboratory apparatus designed to accomplish the above method, or in a similar online apparatus set up in a semi-batch mode or continuous mode.

  • Publication number: 20120198923
    Abstract: The present invention describes the connecting of a corrodible material with a non-corrodible material by electron beam welding so that the corrodible material is not affected by non-corrodible material during the welding process. Employing an electron beam welding process not only minimizes unintended alloying of the corrodible element but also minimizes the width of the weld heat affected and fusion zones. This fabrication method is necessary to ensure that the corrodible element faithfully replicates the wastage of the subject metal.

  • Patent number: 8191406
    Abstract: A method for treating or preparing a fuel rod cladding tube in such a way that an influence of iron oxide deposits on its surface can be studied and assessed precisely under virtually operational conditions with as little risk as possible, includes at least partially coating the fuel rod cladding tube with an iron oxide layer by immersing it in an aqueous electrolyte medium which contains iron oxide particles. The iron oxide particles are produced by anodic oxidation of an iron-containing working electrode. A test body and a device for pretreating a fuel rod cladding tube with an electrochemical three-electrode configuration, are also provided.

  • Patent number: 8166804
    Abstract: A method for detecting separation in a structure that comprises at least two portions or layers affixed together comprises forming a cavity into the structure that passes through an interface formed between the two portions and plumbing the cavity to a monitoring system. A pressure differential is established between the cavity and a reference pressure to which the structure is exposed. A monitoring system monitors for a change in the pressure state of the cavity. Changes in the pressure state are indicative of a separation between the portions or layers.

  • Patent number: 8161804
    Abstract: A support stand for supporting a test piece within a corrosion chamber comprises first and second side members interconnected by first and second support rods. The relative position of the support rods is adjustable so as to modify the orientation of the test piece. In some examples, each side member has a base, a first row of spaced-apart holes generally parallel to the base, and a second row of spaced apart holes generally perpendicular to the base. By selecting the holes with which the support rods engage, the orientation of the test piece can be set to a predetermined value.
