We are leading Manufacturer of ASTM A516 gr 70n Spectacle Blind Flanges, Check latest price list of SA516 GR70N Spade Flange

The SA 516 Gr 70 is part of a boiler vessel grade. The SA 516 Gr 70 Flange is designed with a chemical composition of carbon, silicon, manganese, phosphorous, sulfur, aluminum, chromium, nickel, molybdenum, copper, niobium, titanium, and vanadium. The superior content gives these flange types good corrosion and oxidation resistance properties. AN A516 gr 70 Flange works well in moderate to low pressure and temperature applications. The high-strength flanges don’t disorientate under any conditions as they process and store volatile fluids and gases within the system. All these flanges are quality assured and are produced with the best-in-class material and latest technology under the guidance of our esteemed workers.

SA 516 Gr 70 Spade flange according to ASME B16.48 specification, buy A516 GR70 Paddle Blind Flanges at lowest price in Mumbai

An A516 Gr. 70 Spectacle Flange is a special type of flange that is designed comprising of two metal discs that are attached to the middle of the flange by small sections of steel. The versatile SA 516 Gr 70 Spectacle Blind Flange is designed with a minimum tensile strength of 510 N/mm2 with a minimum yield strength of 335 N/mm2. These flanges can be used to effectively terminate the flow of fluids and gases in the system. The A516 Gr. 70 Spade Flange is commonly seen in pipelines during maintenance and shut down for a very long time. These flanges act similar to the blind flange and isolate one side of the pipe. The ASTM A516 gr 70n Spectacle Blind Flange is supplied in normalized conditions. These flanges consist of a spacer that allows for fluid flow to take place effectively without the need for removing the flange or other components. The versatile SA 516 Gr 70 Killed Carbon Steel Slip Blind Plate has a very uniform analysis and is relatively free from aging. These plates are comparatively harder than rimmed steel components.

Ramesh Steel Corporation supplies all Large-Diameter ASTM A516 GR 70N Spectacle Flange with MTC, SA 516 GR 70N Spec Blinds available in Cass 150 to 2500# pressure
