Ashtapad is a specialised manufacturer of high quality ASME/ANSI/DIN industrial Blind Flanges in India. We offer immediate delivery programs for standard size of carbon steel Blind Flanges and stainless steel Blind Flanges. Plate Blind Flanges manufactured in special stainless steel grades, nickel alloy and alloy steel can be supplied with just in time programs.

Commonly referred as blanking flanges, Blind pipe flanges are widely used in high pressure applications. Blind Flanges are generally used to seal the end of a piping system to prevent flow of liquids or gases. The use of Blind Flanges allows ease of access to a piping system once it has been closed.

Our Blind Flanges are available with raised or RTJ faces and also with female threads. Blind Flanges can be supplied with or without hub as per the customer requirements.

We offer blind plate flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.

Our products are widely exported to countries and regions such as the United States, Europe, Russia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Thailand, Singapore, Colombia, and Sri Lanka.
