Table Of Content
Ally International Co is a reputed manufacturer of high quality ASME/ANSI/DIN standard blind flanges. We are well known as Blind flange Manufacturers in India, 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 offered ASME B16.5 Blind Flange is just like standard pipe flanges, can be raised face (RF) or flat faced (FF). ANSI B16.5 Blind Flanges[ANSI B16.5 BLRF] is very much resistant to chemical corrosion and oxidation (corrosion resistant), and has some high stress-rupture effectiveness and low creep rates under high stresses at temperatures after suitable heat treatment.
We offer JIS blind flanges has excellent resistance to chloride-ion stress-corrosion cracking, and as well shows appropriate resistance to a number of oxidizing environments. Blind Flange is 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 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.

Blind Flange Applications
Our offered Blind Flanges used in many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, mostly because the substance inside must differ from the substance outside in composition or pressure. ASME B16.47 Blind flanges do this by fastening two pieces of metal or other material together with a circle of bolts on a lip. This “lip” is a flange.
