Simplex Fittings is one of the leading Blind Flanges manufacture, supplier and exporter in Mumbai India. We manufacture and supply these Blind flanges in various grades like stainless steel, carbon steel, duplex, and super duplex steel, high nickel alloys, and many more materials. Blind Flanges are used to block off a section of a pipe or a nozzle on a vessel that is not used.

Super Duplex Steel Blind Flanges are prone to stress-corrosion cracking, crevice corrosion, pitting, erosion and general corrosion. Hastelloy blind flanges have outstanding resistance to corrosion in both oxidizing and reducing environments, which makes them well suited for a range of strong corrosive uses. Inconel blind flanges can be used in service temperatures ranging from cryogenic to 2200 degrees F (982 degrees C) because of its high thermal stability. Incoloy Blind Flanges is commonly used at elevated temperatures for its resistance to seawater, brine, sour gas and high chloride environments making it a common option in the oil and gas and power industries. An outstanding feature of Monel blind flanges is that in all concentrations up to the boiling point they give exceptional resistance to hydrofluoric acid, which is an especially tough acid to handle. Titanium Blind Flanges are used in many industries including Chlor alkali, marine, off-shore oil & gas, desalination, medical, and pulp and paper. The high-temperature properties of Stainless Steel Blind Flanges make them ideal for ore processing, steel plants, power generation, and sintering. Cryogenic structures often use SS blind flanges for their strength at -450 degrees F and low magnetic permeability.

We stock Blind flanges in various sizes, pressure ratings, standards, face types, etc. we also customize these according to client specifications at the most reasonable prices. We offer a variety of blind flanges which are precision engineered using raw material of the finest quality. Our range complies with proven quality standards and is known for its precision size and durability.
