Miscellaneous technical articles about mechanical and electromechanical products for projects
Over the years, people who are involved in the oil and gas industry have been innovating and creating ways to get accurate measurements. From extracting to delivering these raw materials, everyone in the business has been deeply invested in getting the most accurate measurements possible. Thus, scientists and engineers have been working long and hard… read more »
Compression fittings are used to create leak-free tube connections easily and quickly. Double ferrule compression fittings feature an outer nut, two deformable ferrules in soft alloy or non-ferrous metals and, a tube fitting body and are available for metric and fractional tube sizes. When the fitting nut is screwed on the tube, the ferrules get deformed to… read more »
BWG and SWG are alternative measurements for steel tubing sizes (outside diameter and wall thickness). BWG stands for “Birmingham Wire Gauge” (or “Stubs Iron Wire Gauge”). Each BWG number (example from 10 to 22) represents a specific steel tubing thickness, which can be converted in inches or mm. SWG stands for “Standard Wire Gauge” (also… read more »
A complete collection of the most used P&ID symbols for lines, piping, valves, instruments, pumps, compressors, pressure equipment and other mechanical equipment. WHAT IS P&ID? P&ID is the acronym for “Piping and instrumentation diagram”, i.e. a very detailed diagram showing the processes happening within a plant, the involved equipment, and their interconnections. A set of… read more »
An overview of key concepts about process instrumentation: measurement precision (a static feature that identifies the degree of agreement between the indication of the instrument and the characteristics of the measurand in measurement or monitoring), measurement uncertainty, metrological confirmation, and calibration. MEASUREMENT PRECISION By measurement precision we mean: according to ISO-IMV (International Metrology Vocabulary): “…closeness of agreement… read more »
This post illustrates the steps from the initial block and flow diagrams to achieve the final Piping & Instrumentation Diagram (P&ID) diagrams required for the interpretation and governance of process plants, as well as to highlight and report on the video pages of the Distributed Control System (DCS) measurement and control loops suitable for the… read more »
