20100324852 | DETERMINING THE RESONANCE PARAMETERS FOR MECHANICAL OSCILLATORS - The prior art describes the application of mechanical oscillators for the measurement of corrosion and/or deposition. Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. However, the prior art does not consider the required precision for measuring frequency or Q in the presence of noise to make these measurements. In particular, the ability of the mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. The present invention discloses methods for measuring these resonance parameters with a high precision in the presence of noise. This degree of precision is required to maximize the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement. All of the embodiments described herein employ curve fitting consistent with modeling the mechanical oscillator as a simple harmonic oscillator. This curve fitting procedure, combined with averaging and utilizing signal processing parameters to mitigate noise effects, adds considerable precision in measuring resonance parameters. | 12-23-2010 |

20140134743 | METHOD FOR IDENTIFYING LAYERS PROVIDING CORROSION PROTECTION IN CRUDE OIL FRACTIONS - A method for determining and identifying corrosion protective layers that provide corrosion protection against crude oils and crude oil fractions is disclosed. The method identifies naturally occurring constituents in crude oils that indirectly provide corrosion protection. A method assessing the potential of these constituents is also disclosed. The method includes exposing metal coupons with the crude oil or crude fraction of interest at the expected operating temperature of concern. The corrosion potential assessment further analyzes the exposed coupons with transmission electron microscopy and an additional high temperature exposure that challenges the tenacity of the protection offered by the corrosion protective layer. | 05-15-2014 |

20110174060 | AT REST VACUUM STATE FOR VACUUM DECAY LEAK TESTING METHOD AND SYSTEM - A method and apparatus for leak testing of liquid and non-liquid filled rigid and semi-rigid nonporous containers wherein a container is enclosed in a conforming test chamber and subjected to vacuum while the pressure within the chamber is monitored by an absolute pressure transducer, alone or in combination with a second differential transducer, to determine if leaks are present in the container and wherein the test apparatus or system remains under low pressure or vacuum conditions while leak tests are not actively in progress such that the system is maintained at an at-rest low vacuum condition to minimize pressure sensor drift and to eliminate build-up of vapors or gases within the apparatus or test system between tests that may hinder the speed and sensitivity of the leak tests. | 07-21-2011 |

20150106036 | DETECTION OF CORROSION RATES IN PROCESSING PIPES AND VESSELS - For a monitored corrosion sensor, such as a sensor based on one or more mechanical oscillators disposed in a fluid flow, one or more values are measured over time. The values can be measured at a desired frequency, such as a once per second, once per minute, or another convenient frequency. The measured data can then be analyzed as a time series. The goal of the analysis is to identify variations in the time series data that are sufficiently unexpected relative to the prior behavior of the time series within a given time window. The identified variations can then, for example, be excluded from consideration when determining a corrosion-related value for the sensor. | 04-16-2015 |

20080314150 | Mechanical oscillator activated or deactivated by a predetermined condition - The present invention is a mechanical oscillator for detection and measurement of corrosive or foreign materials. The elements include a means for mechanical excitation, and a mechanical oscillator, wherein said mechanical oscillator has a resonant frequency, f, and a quality factor, Q. A fuse fixed to the oscillator to change oscillator amplitude to or from essentially zero to resonance amplitude. In a preferred embodiment, the mechanical oscillator has the shape of a tuning fork where one region is compatible with the service fluid and the other region is incompatible with the service fluid or other contaminant.

20120198923 | METAL LOSS PROBE AND METHOD FOR FABRICATING THE METAL LOSS PROBE - 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. | 08-09-2012 |
20130122593 | TUNING FORK OSCILLATOR ACTIVATED OR DEACTIVATED BY A PREDETERMINED CONDITION - A sensor for detection and measurement of incompatible (corrosive or foreign) materials in a fluid medium. The sensor includes a tuning fork mounted on a diaphragm with tines having an amplitude and a resonant frequency. The sensor alarms when a measured amount of the incompatible material has been deposited on the sensor to form a fusing element on the tines which causes vibration of the tines to cease. | 05-16-2013 |
20130186168 | SYSTEM AND METHOD FOR ENHANCING CORROSION RATE DETERMINATION IN PROCESS EQUIPMENT USING A TELESCOPING/ROTATING SENSOR - A system and method for optimizing the response of a metal loss sensor which is configured in a way that its insertion depth and orientation in the process fluid are adjustable. These adjustments affect local turbulence and thereby enable achieving a desired corrosion rate at the metal loss sensor. Corrosion rate comparison between the metal loss sensor and pressure containment boundary can be measured directly or indirectly by computing wall shear stresses at the sensor and the pressure containment boundary. | 07-25-2013 |
20130191038 | METHOD FOR QUANTIFYING CORROSION AT A PRESSURE CONTAINING BOUNDARY - A method for determining the amount and rate of corrosion which has occurred on the surface of a process unit by measuring corrosion with a corrosion sensor and measuring at least one parameter inside the process unit.
