The Expanite\u00ae surface hardening process ensure that your products meet all the demanding requirements of the Pumps & Valves industry where the main problems always have been wear, erosion, cavitation, galling<\/a> and corrosion. Valves and pu<\/a>mps<\/a> exposed to harsh environments require enhancement to prolong the lifetime of their parts. Surface hardening plays a significant role in protecting the components from wear driven e.g. by abrasion elements in fluids or cavitation, galling especially on contact areas in movement relative to each other and corrosion when exposed to aggressive media.<\/p>\n Independent of the operation area of pumps & valves – oil & gas, food & beverage, pharma & chemical, power plants or general industry applications e.g. hydrogen storage and transport -, process safety has a top priority, hence placing high demands for the equipment in usage. At Expanite we understand that downtime means lost revenue and take pride in offering the fastest lead time in the industry at an extremely competitive price level.<\/p>\n<\/div>\n Expanite heat treatment solutions are designed for applications where wear, corrosion, galling or early component failure can impact performance and profitability \u2014 helping stainless steel and other high-value materials achieve extended service life.<\/p>\n<\/div>\n Galling, sticking and wear can compromise valve movement and reliability, especially in demanding or hygienic environments. Expanite improves surface performance so valve components move more smoothly, last longer and perform more consistently.<\/p>\n<\/div>\n ISO9001:2015 compliant<\/a><\/p>\n<\/li>\n When it comes to conveying abrasive media surface hardening of the affected pump rotors and housings increases wear resistance and therewith lifetime of the pump in service. For some valves hardening of the stainless steel surface is essential to reduce the risk of galling during the start-up phase and while maintaining or even increasing the corrosion resistance the Expanite technology is well suited and meanwhile widely spread e.g. for food & beverage applications.<\/p>\n Surface hardening of stainless steel is also common for various valve components starting from balls with related sealing parts, bushings and guiding rings, control cones, wedges up to shafts, spindles and even complete valve housings. Especially on relatively large valves used in the chemical industry and power plants, galling on shifting shafts made of Inconel and Monel<\/a> has previously caused severe problems but Expanite is the solution meeting the requirements of the industry.<\/p>\n Applying the Expanite hardening will guarantee you the most ideal heat treatment of your products preventing galling and thereby increasing the lifetime of your components.
