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.

A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500. It used in more industries than carbon steel as stainless steel has better resistant performances on corrosion environment and always provides with a good appearance.

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]

304 also contains 8-10.5% nickel (Ni). It is added to make the austenite structure more stable at room temperature. Nickel also improves high temperature oxidation resistance, making the steel resistant to stress corrosion cracking. Where the steel is to be stretch formed, a lower percentage (8%) of nickel should be chosen. Higher percentages are better (9% or more) if the steel is to be deep drawn.

A higher Carbon version, SS UNS S13009 Blind Flanges are excellent in such cases, they are resistant to carbide precipitation as well.

The stainless steel flange is austenitic chromium nickel stainless steel, which has good oxidation resistance and corrosion resistance. Due to the high content of chromium and nickel, it has better creep strength, can work continuously at high temperatures, and has excellent high temperature resistance.

Stainless steel, also known as inox steel, is a steel alloy with at least 10.5 or 11% chromium by mass.

S31803 is the Unified Numbering System (UNS) designation for the original duplex stainless steel. The UNS system was created by multiple trade groups in the 1970s to reduce confusion when the same alloy was called different things, and vice versa. Each metal is represented by a letter followed by five numbers, where the letter represents the metal series, i.e. S for stainless steel.

For paper mill applications requiring lower alloy grades that do not have sufficient corrosion resistance. Based on a 22% chromium content, they have a combined austenitic:ferritic microstructure that provides greater strength, corrosion resistance and cost-effectiveness.

The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60). This reflects their desire to maximize the alloy’s corrosion properties, thanks to the development of the AOD steelmaking process, which allows for tighter control of composition. In addition, it allows to influence the nitrogen addition level rather than just being present as a background element. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).

Stainless steel is an alloy of iron that is resistant to rusting. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.

316 stainless steel is more resistant to corrosion than 304 stainless steel, especially chlorides. This makes it a common choice for applications where marine equipment and other materials are exposed to extremely high concentrations of chlorides or other oxidizing agents. However, 304 stainless steel still has excellent corrosion resistance, so this is usually only a factor in marine environments and other high corrosion locations.

A typical AL-6XN weld has non-uniform freeze lines and oxide islands in the weld bead. These oxide islands appear as a thin film, having a varying color with tints from gray to dark brown that adhere to the surface.

Type 304 stainless steel is a T 300 Series Stainless Steel austenitic. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is defined as a Chromium-Nickel austenitic alloy.304 stainless steel is used for a variety of household and industrial applications such as food handling and processing equipment, screws,[3] machinery parts, utensils, and exhaust manifolds. 304 stainless steel is also used in the architectural field for exterior accents such as water and fire features. It is also a common coil material for vaporizers.

The ASME SA182 SS 310 Pipe Flanges can come in ASTM A182 or A240 specifications and ANSI, ASME, BS, DIN and EN standards. The dimensions range from 1/2 inches to 48 inches but there are different standards for special purpose flanges and their dimensions as well.

Annealing between 1050 and 1080¡ãC can be done after forging, followed by rapid quenching, especially to restore corrosion resistance, but there is no heat treatment to harden 316L.

316L is a better choice as 316 is more susceptible to weld corrosion than 316L (corrosion within the weld). However, 316 can be annealed to resist weld decay. 316L is also a premium stainless steel for high temperature, high corrosion applications, which is why it is so popular in architectural and marine projects.
