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.

Alloy flange material (chromium molybdenum) has higher chromium and molybdenum content than carbon steel flanges. Alloy steel flange materials are suitable for high temperature and high pressure applications and have higher corrosion resistance than conventional carbon steel flange grades. ASTM A182 alloy flanges are extremely ductile, strong and tough, easy to weld, and resistant to oxidation and oxidation. These grades are compatible with ASTM A335 alloy steel pipe.

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 high molybdenum content of 254SMO stainless steel makes it have a higher oxidation rate when annealed, resulting in a rougher surface after pickling than ordinary stainless steel. However, this has no adverse effect on the corrosion resistance of the steel.

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.

Alloy 316H (UNS S31609) is a high carbon modification of Alloy 316 developed for high temperature service. This alloy has higher strength at elevated temperatures and can be used in structural and pressure vessel applications above 932¡ãF (500¡ãC). The higher carbon content of 316H also provides higher tensile and yield strengths than 316/316L, and its austenitic structure provides excellent toughness at low temperatures.

AL-6XN is an alloy that is an austenitic stainless steel. It is often referred to as a super austenitic stainless steel because it has several useful properties. One of the main benefits of using al6xn bolts is that it can be used in high temperatures. Meanwhile, AL6XN is a super austenitic alloy, and the most abundant element is iron. It is the most popular of the 6% molybdenum alloys. Common uses are in the food processing, pharmaceutical and biotechnology industries. It exhibits superior corrosion resistance compared to duplex alloys in most environments. Due to the lower nickel content, AL6XN fasteners are generally more economical than high nickel alloy fasteners.

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.
