Stainless Steel ANSI Norm Flanges Fittings
ANSI Norm Flanges Fittings refer to a set of standards for flanges used in piping systems, established by the American National Standards Institute ANSI. These flanges are designed to provide a secure and leak-proof connection between two pipes or other equipment.
ANSI Norm Flanges Fittings come in different sizes and pressure ratings, with the most commonly used sizes ranging from 1/2 inch to 24 inches in diameter. They are typically made of materials such as carbon steel, PS Steel Stainless Steel Flanges and Pipe Fittings, or alloy steel.
There are several types of ANSI Norm Flanges Fittings, including slip-on flanges, threaded flanges, socket weld flanges, blind flanges, and weld neck flanges. Each type has its own unique features and is suitable for specific applications.
To ensure that the flanges meet the ANSI standards, they undergo rigorous testing and inspection procedures, including visual inspection, dimension measurement, and hydrostatic pressure testing.

Corrosion Residant Stheel That We Offer
AISI 302
An austenitic PS Steel Stainless Steel Flanges, which because of its ability to attain high strength and ductility through moderate or severe cold working, can be used for automobile trims, conveyor belts, transportation cars such as railway coaches, metal fixtures for construction purposes,, roof drainage products storm door frames and tableware.
AISI 304
It is the most widely used austenitic PS Steel Stainless Steel Flanges. Popularly known as 18/8 PS Steel Stainless Steel Flanges, it has excellent corrosion resistance and forming characteristics. Used in chemical, petrochemical, and fertilizer industries and as equipment in dairy, food processing, pharmaceutical industries, hospitals, and households as kitchenware, cryogenic vessels as heat exchangers in air conditioning refrigeration, for machinery in paper, pulp, and textile beverage sectors.
AISI 304 L
An austenitic PS Steel Stainless Steel Flange similar to AISI 304 with less carbon (0.03%) is used in place of AISI 304 for improved resistance to intergranular corrosion it is used for parts and structures which cannot be heat treated for stress relieving after welding.
AISI 309/AISI 309 S
These are austenitic PS Steel Stainless Steel Flanges which are strong and tough. Because of their higher nickel and chromium content, they are used for applications requiring high scaling and corrosion resistance. They find their use for air heaters, annealing boxes, back oven equipment, boiler baffle pates, carburizing boxes, chemical processing equipment, dryers, exhaust manifolds, furnace parts, gas turbine parts, heat exchangers, jet engine parts, oil burner parts, oven equipment, petroleum refining equipment, etc.
AISI 310/AISI 310 S
These are austenitic types with higher chromium and nickel content than 309/309S. Because of their relatively high creep strength and mechanical properties at higher temperatures, these steel are available for higher temperatures and severe service conditions. They were used for air heaters, annealing boxes, ovens, carburizing boxes, fire box sheets, furnace linings, furnace stacks and dampers, gas turbines parts, heat exchangers, kiln linings, nozzle diaphragm assemblies for turbo jet engines, oil burner parts paper mill equipment, oil refinery equipment recuperators and so on.
AISI 316
An austenitic PS Steel Stainless Steel Flanges with 2.0 to 3.0 Percentage Mo. which is corrosion resistant and imparts hot strength characteristics for applications requiring resistance to pitting corrosion halogen atmospheres. Typical applications: architectural marine exteriors., chemical processing equipment, food proc equipment, petroleum refining equipment, pharmacy equipment, photographic equipment, pulp and paper proc- equipment, textile finishing equipment, etc.
AISI 316L Flanges Dimensions
An austenitic PS Steel Stainless Steel Flanges is a modification of type AISI 316 (com a maximum of 0.03 percent carbon) with a reduced tendency toward carbide precipitation without the addition of a stabilizing element. Recommended for parts that cannot be heat treated after welding,
AISI 317/AISI 317L Flanges Dimensions
There are austenitic PS Steel Stainless Steel Flanges which are modifications of the type
AISI 316/AISI 316 L and offer increased chromium, nickel, and molybdenum ranges for improved corrosion resistance. The steels were developed to resist the attack of sulfurous compounds. They resist Fitting in phosphoric and acetic acids. The application includes paper pulp handling equipment, process equipment, for producing photographic chemicals, bleaching solutions, and handling sulfurous acetic, formic, citric, and tartaric acids. They have the best corrosion resistance to body acids and blood and are recommended for surgical bone application.
AISI 321 Flanges Dimensions
An austenitic PS Steel Stainless Steel Flanges similar to AISI 304 but stabilized with titanium to avoid intergranular corrosion. Type AISI 321 resists scaling and vibration fatigue. It is used for aircraft exhaust stacks and manifolds, pressure vessels, large mufflers for stationery diesel engines, carburetors, expansion bellows, stack liners, firewalls, etc.
AISI 347 Flanges Dimensions
An austenitic PS Steel Stainless Steel Flange similar to AISI 321 but stabilized by Columbium does not appreciably reduce the overall corrosion resistance. Recommended in the range of 240° to 900° C for parts fabricated by welding and which cannot be subsequently annealed applications include airplane exhaust stacks, welded tanks for chemicals, heat resistors, jet engine parts, expansion bellow, etc.
AISI 409 Flanges Dimensions
It is the lowest alloyed straight Chromium ferritic PS Steel Stainless Steel Flanges. It replaces carbon steels and low alloy steels where some amount of heat or corrosion resistance and higher strength are required and where appearance is secondary. It is used for finds in heater tubes, transformer, and capacitor cases, dry fertilizer spreaders, automotive exhaust systems including mufflers, resonators, silencers, pipes and emission control units, high-pressure agricultural spray tanks, culverts, shipping containers, and farm types of equipment.
AISI 410/410S Flanges Dimensions
AISI 410 is the most commonly used 12% Chromium martensitic PS Steel Stainless Steel Flanges. An excellent combination of toughness and strength can be developed through proper heat treatment. This steel has better corrosion resistance in hardened conditions. It is a good choice when good formability and high strength are required and the end use demands resistance to a mildly corrosive environment. It is used for furnace parts and burners operating below 650°C micrometer parts, tray supports, caps and vaporizers in petroleum fractionating towers, lining for reaction chambers, coal screens, fishing tackles, keys, lamp brackets, rules and tapes, wall screens, steam turbine buckets, blades, buckets covers, pump parts, petrochemicals equipment, and press plates: Type AISI 410 S is low carbon modification of AISI 410
