Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 317L Hydraulic Fittings, where their uses are expanding in a variety of markets. To meet the requirements of the new Clean Air Act, coal – fired power plants are installing SS 317L Hydraulic Type Fittings. Other new industrial applications of Stainless Steel 317L Forged Hydraulic Fittings include secondary heat exchangers for high – efficiency home furnaces, service – water piping in nuclear power plants, ballast tanks and fire – suppression systems for offshore drilling platforms, flexible pipe for oil and gas distribution systems, and heliostats for solar – energy plants.
Environmental legislation is also forcing the petrochemical and refinery industries to recycle secondary cooling water in closed systems of Stainless Steel 317L Hydraulic Forged Fittings rather than simply discharge it. Reuse of 317L Stainless Steel Hydraulic Fittings results in cooling water with elevated levels of chloride, resulting in pitting – corrosion problems.
These 317L Stainless Steel Hydraulic Type Fittings will play an increasingly important role in solving such industrial corrosion problems, since it costs less than other materials. Manufacturers are developing highly corrosion – resistant 317L Stainless Steel Forged Hydraulic Fittings in respond to this demand. These SS 317L Hydraulic Fittings are a very broad group of metals, which has with a minimum of 10.5 % chromium, where the chromium gives the steel its ‘stainless’ properties – essentially corrosion resistance.
