ANSI B16.5 / ASME B16.47 Square Flange Supplier, Manufacturer in India
Unichem Steel & Alloy Pvt. Ltd. is one of the simplest Manufacturers and Exporters of Square Flanges which are utilized in hydraulic systems to attach a pipe to a component or a pipe to pipe connection. as the name implies, Square Flanges are squarely shaped. It makes in accordance with different standards based on various countries, Square Flanges are available for different pressure ratings in order to fulfill their purpose. With square flanges, you’ll ensure seamless flow of liquids through stainless and steel pipes or the other hydraulic systems. Square flanges are available in different sizes from 1/4 inches to 6 inches. The common size for system installation is 1/2 to 2 inches. The square flange is often classified as two materials which are steel or chrome steel. it’s made from SF440A steel or SS316 stainless steel. they’re made to fit the standards of JIS B2291 also as JIS F7806. Square flanges can withstand high pressure moving connected pipe, and there are three different pressure scales: 210kg/cm², 280kg/cm², and 350kg/cm². The square flange is very useful in multiple high-pressure industries like connections between pipes, also as between pipes and other components that are necessary to induce a full system working. The square flange can add many various situations, but it’s considered most useful when working in small diameter pipes. it’s not recommended for larger diameter pipes, where there’s an oversized weight load working within. the square flange isn’t ideal to work well under a high torque environment. a whole set of Square Flanges included 5 important parts. it’s 1 piece of female side, label as Aside, 1 piece of male side, label as B side, 4 pieces of hexagon or Allen cap screws, 1 piece of NBR 70/90 oring, and 4 pieces of hexagon nut.
