Shipham Valves' New Range of Wafer Check Valves
Wärtsilä subsidiary, Shipham Valves, completes development of a range of composite single plate wafer check valves. The new valves will be introduced to the market place at the Valve World Exhibition to be held in Düsseldorf at the end of November. Available in sizes from 3” – 12” / DN80 – DN300 and rated at 16 bar (230psi), the single plate Wafer Check Valve adds to Shipham Valves existing range of composite valves. The latest range is a compact, lightweight, fully non-metallic valve and comprises only two components - the body and the disc.
Synergy Produces Superior Boat Lift
Synergy Between Boat Lift Manufacturer, Electrical Products Distributor and Fiberglass Enclosure Manufacturer Results In Superior Product Offering. Synergy --- different elements working together to produce results not obtainable by any of the elements alone --- is what happens when three companies work together to achieve high-quality results. Fifteen years ago Hi-Tide, Graybar and Stahlin Non-Metallic Enclosures began working together to provide boat lift customers with controls that can survive in very harsh environments including exposure to water, salt, corrosives and ultraviolet rays.
Increasing the Life Expectancy of Marine Equipment
Alan Robinson, managing director of Arc Energy Resources, discusses the benefits of weld overlay cladding to protect marine equipment and components from corrosion; and reviews the options available using corrosion resistant alloys. Paints and coatings are readily available to protect surfaces of a ship’s superstructure from saltwater in the atmosphere, but how can marine engineers ensure the long-term integrity of mechanical components and equipment such as pumps, valves and piping against aggressive corrosion caused by the sea itself, either below the surface or in areas subjected to significant amounts of saltwater spray. In order to maintain the efficient and reliable operation of marine equipment…
