  • Modelling study of liquid crystals orientation in the presence of corrosion potential

    The anchoring and orientation of liquid crystal (LC) molecules are influenced by several parameters. This paper presents theoretical work that aims to explain how surface changes and potential due to corrosion, affect the LC orientation and anchoring. This work is done with a view of enabling the design and development of a LC based corrosion ...

  • Higher corrosion resistance of old cast iron pipes installed for early stage of water supply network in Yokohama City

    The old gray cast iron for water supply pipes in Yokohama City which was made in the UK in 1887 is highly corrosion resistant. The corrosion behavior of the old gray cast iron in soils was studied. For comparison, a gray cast iron used for modern pipes, a spheroidal graphite cast iron, and a carbon steel were tested. The corrosion potentials and corrosion rates were measured. The corrosion ...

  • Ultrasonic Hull Inspections: How to Find the Right Equipment

    Hull inspections keep crew, ship, and cargo safe at sea. Not only is it plain good sense to periodically ensure the seaworthiness of any vessel, but it can also be required by law for ships registered in the U.S. and other countries. Hull inspections can be conducted visually in some cases, but for the best results, ship owners rely on nondestructive testing. Marine nondestructive testing, such ...

  • Difference between Seamless and Welded Steel Pipes and Tubes

    Pipes are usually produced by two distinct methods which are a welded pipe or a seamless pipe. In both methods, raw material is first cast into ingots. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld.The following are the main differences between seamless and welded ...

  • Cogen plant produces distilled water for resale

    The Facility Panda Energy’s power plant located in Brandywine, Maryland is a cogeneration facility that produces electricity by using gas and steam turbines. The Problem The objective of Panda Energy was to achieve Qualified Facilities (QF) status at their Maryland location. To achieve this, they had to produce distilled water using the steam from ...

  • Evaluation of groundwater quality and assessment of scaling potential and corrosiveness of water supply networks, Iran

    The aim of this study was to determine the corrosion and scaling potential of water supply sources in a province in eastern Iran. In this cross-sectional study, 879 samples were taken to evaluate the water quality characteristics during 12 months (2013–2014). Five indices, Langelier, Ryznar, Puckorius, Larson–Skold, and Aggressiveness, were programmed in Microsoft Excel. The results ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

  • Does Your Ultrasonic Sensor Need Maintenance?

    Maintenance is important, but it’s often hard to quantify. How much time does maintenance take? How often does your system need it? Does maintaining one part necessitate a complete system shut down? What does that represent in lost income because your system is not making product? Maintenance is important, but minimizing maintenance is even more important. Maintenance is also important for ...
