Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then revalidated at regular intervals according to the relevant standard.
Oil sampling is a procedure for collecting a volume of fluid from lubricated or hydraulic machinery for the purpose of oil analysis. Much like collecting forensic evidence at a crime scene, when collecting an oil sample, it is important to ensure that procedures are used to minimize disturbance of the sample during and after the sampling process.
In this test, a sample is heated at 250 °C for 60 minutes with a constant flow of air over it. The weight fraction lost is the result for the Noack volatility test. As the lighter hydrocarbon fraction of motor oils evaporate, the viscosity of the remaining oil increases, contributing to poor circulation, reduced fuel economy , increased oil ...
Skydrol is a brand name of fire-resistant hydraulic fluid [1] used in aviation and aerospace applications. It is a phosphate ester-based fluid that is known for its excellent fire resistance and ability to withstand extreme temperature and pressure conditions.
A test patch should be as clean as possible. Contamination of a patch can influence the results significantly. Bresle patch injected with 15ml water as in ISO 8502-6 Annex A. The ISO 8502-6 standard prescribes in annex A that certified patches shall be used. This annex describes a stress test to ensure patch adhesion and wash ability.
A "mud man" is the drilling fluids technician responsible for formulating the mud, while a "mud logger" checks mud cuttings from the drill bit for traces of rock or oil and gas that provide a picture of conditions downhole. Negative Pressure test: A test performed to determine the integrity of wells.
Tracers are used in the oil industry in order to qualitatively or quantitatively gauge how fluid flows through the reservoir, [1] as well as being a useful tool for estimating residual oil saturation. Tracers can be used in either interwell tests or single well tests. [2]
Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323 ...
