Velan announces that the research made with Hardide about the tungsten carbide CVD coating for its pressure Class 600 valves has reached an end, and an industrial implementation can be immediately performed.
Hardide coatings are able to extend the service life of critical components across a wide range of high-wear/high-value industries, like O&G, petrochemicals, aerospace ones, where down-hole tools, control valves, cylinders, rotors, pistons, pins, landing gear, turbine blades, and many flow control components are subjected to strongly corrosive agents and intense erosion.
This new kind of coating is applied by a modern CVD technique, that can guarantee a compact, high-quality nanosized coating, much more resistant than conventional HCP (Hard Chromium Plating) coating and with few compromises about costs.
This new technology has been tested on a Torqseal triple-offset butterfly valve, and the coating performance was tested with the collaboration of Polytechnique Montreal University.
Velan also announced that a new “V” coating code has been created, and a price list developed to expedite quoting and the order entry process. Future work will include testing on Power Ball valves to determine where Hardide can offer performance and price advantages over other coatings.
