The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Grades 309/309S are austenitic chromium-nickel stainless steels typically used in high temperature applications. Due to the high chromium and nickel content, grade 309/309S pipe is highly resistant to corrosion and has excellent resistance to oxidation. 309 Stainless Steel Threaded Rods are austenitic stainless steel threaded rods made from an alloy containing chromium and nickel. Stainless steel 309 threaded rod for low temperature service and highly corrosive environments. Additionally, 309 stainless steel has better corrosion resistance than 304 due to its higher nickel and chromium content. The alloy has been used in furnace parts, high temperature vessels, welding wire and fire box panels.

Type 304 is slightly less strong than 302 due to its lower carbon content. Type 304 is widely used in welding applications because the low carbon allows some exposure in the carbide precipitation range of 800¡ãF – 1500¡ãF without the need for post-annealing operation.

Stainless steel is an iron alloy containing at least 10.5% chromium. Chromium produces a thin layer of oxide on the surface of the steel, called a “passivation layer”.

The high alloying of the material is giving 904L chloride stress corrosion cracking resistance but still, the material is susceptible.

SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

The high chromium content promotes and maintains a passive film that protects the material in many corrosive environments.

The flanges may be made from forgings, castings, or plates covering various types and classes of ASME B16.5 and ASME B16.47 (both Series A and Series B). Stainless steel 304/ 304L flanges of ASME B16.5 are available in Classes 150, 300, 400, 600, 900, 1500, 2500.
