About Arcellor Controls Arcellor Controls is a reputed manufacturer of high-quality ASME/ANSI/DIN standard blind flanges. We are well-known as blind flange manufacturers in India, offering products to block off a section of pipe or a nozzle on a vessel that is not used. A Blind Flange (BLRF) is a plate for closing or covering the end of a pipe. If the blind flange is a standard ASME B16.5 flange, the OD of the gasket will be the same as the OD of the standard ring or standard full face gasket.
Our ASME B16.5 Blind Flanges can be raised face (RF) or flat face (FF). ANSI B16.5 Blind Flanges (ANSI B16.5 BLRF) are highly resistant to chemical corrosion and oxidation and have high stress-rupture effectiveness and low creep rates under high stresses at elevated temperatures after suitable heat treatment.
We offer JIS blind flanges with excellent resistance to chloride-ion stress-corrosion cracking and appropriate resistance to a number of oxidizing environments. Blind flanges are manufactured at our facility for various industries, including shipbuilding, power generation, petrochemical plants, oil refineries, wastewater treatment plants, paper mills, pharmaceutical plants, and turnkey projects.
Global Reach Our DIN Blind Flanges are widely exported to countries and regions such as the United States, Europe, Russia, Colombia, Turkey, Malaysia, the UAE, Saudi Arabia, Iran, Brazil, Chile, Mexico, South Africa, Jordan, Tunisia, Vietnam, Indonesia, Singapore, Sri Lanka, and Thailand.
