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.

Alloy 310 can be used for mild oxidation, nitridation, cementation and thermal cycling applications, but the maximum service temperature must be reduced. Alloy 310 can also be used in low temperature applications with low permeability and toughness down to -450oF (-268oC). When heated between 1202 ¨C 1742oF (650 ¨C 950oC), the alloy exhibits sigma phase precipitation. Solution annealing at 2012 ¨C 2102oF (1100 ¨C 1150oC) will restore some degree of toughness.

The lower carbon content of the stainless steel 304 thread bar reduces chromium carbide precipitation from welding and its susceptibility to intergranular corrosion. Stainless steel 304 studs are not particularly thermally or electrically conductive and are non-magnetic. The large number of Style 304 Stud Bolts we manufacture today can be used in products related to the food and beverage industry. These AISI 304 studs are ideal for milk processing, brewing and winemaking as well as yeast trays, pipes, fermentation vats and storage tanks.

The 304, 316 and 316L stainless steel formulations are austenitic, a term used to classify the crystal structure of the steel. The structure is achieved by heat treating at very high temperatures followed by quenching ¨C a rapid cooling process that locks the structural features in place. Austenitic formulations are stronger than martensitic or ferritic steels. Ferritic steels are magnetic, have low carbon content, and have poor corrosion resistance.

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]

Grade F22 is a low alloy steel grade with a chromium content between 2% and 2.5%. The content of chromium and molybdenum is twice that of F11 grade. However, due to the maximum content of all alloying elements up to 5%, it is classified as a low alloy steel grade. As a low alloy steel grade, ASTM A182 F22 flanges outperform carbon steel, especially in applications involving high temperatures.

Stainless steel is an alloy of iron that is resistant to rusting and corrosion. 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
Completely and infinitely recyclable, stainless steel is the ¡°green material¡± par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.
Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.

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.

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.
