Stainless Steel Blind Flanges Manufacturers in India

  • Blind flanges can carry out superior stress from inner pressure and bolt loading from the time when the supreme stresses in the blind flange are meandering stresses at the center. These Flanges are used to outright off the finishes of valves, piping and pressure vessel preambles. Our flanges are supplied through appropriate test certificates of finished products and standard raw materials.

  • Asiamet is a leading manufacturers, suppliers in India. Blind flanges are the plates used for covering and closing the ends of pipes. These have all relevant bolt holes but no center whole. The connection of pipes where the connecting components have flanges through which they are bolted together is called a flange joint. Blind flanges are used to seal the ends of piping systems or pressure vessel openings.
  • Most commonly blind flanges are used for testing the flow of a certain gas or liquid through a pipe or a vessel. Blind pipe flanges are popular as they allow for easy access to the inside of a pipe in cases where work needs to be done inside the line. These are also used for high-pressure applications.

What is a Blind Flanges?

Blind pipe flanges are widely used in high pressure pipe applications. Carbon Steel Blind flanges are available in raised or RTJ faces. Stainless Steel Blind flanges can be supplied to clients with or without hub as per the requirements. Nickel Alloy Blind flanges are generally used to seal the end of a piping system which helps to prevent the flow of liquids or gases. Monel blind flange are widely used for its corrosion resistant properties against flowing sea water and is widely used for marine applications. The alloy 20 material is invented to contribute exceptional résistance to many corrosive environments. we are manufacturer of alloy 20 blind flanges which can be used in reducing environments that acquire sulphuric acid and phosphoric acid. Blind flange which is used for their resistance to attack by acids and alkalis, as well as their high mechanical strength and good ductility.
