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.

The molybdenum content increases corrosion resistance, improves resistance to pitting in chloride ion solutions, and increases strength at high temperatures.

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium¡ªthe alloy that gives stainless steel its famous corrosion resistance. There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.

316L stainless steel is an austenitic alloy often referred to as “marine grade stainless steel” because it is used in nearly 90% of marine applications – including filtration. In addition to metals such as iron and nickel, 316L contains 16-18% chromium and 2-3% molybdenum. These elements are important because they improve the alloy’s corrosion resistance; chromium interacts with oxygen in seawater to form a protective layer of chromium oxide, while molybdenum improves the metal’s resistance to pitting corrosion. Additionally, 316L has a lower carbon content (hence the use of “L” in its name), which gives it better protection against corrosion.

Flanges made of stainless steel are called “stainless steel 304 flanges”, also referred to as “SS 304 flanges”. Common material standards and grades include ASTM A182 Grade F304/L and F316/L, with pressure ratings of 150 to 2500 and 300 to 600, respectively.

Type : Seamless / Welded.This steel type contains as low as 0.03% of carbon content and thus reduces its susceptibility to intergranular corrosion.

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.
A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

For applications where stainless steel tubing or piping must come into contact with food and other sensitive products, sanitation is a high priority. Stainless steel sanitary tubing is used in such applications because it has high corrosion-resistance, doesn¡¯t tarnish, and is easy to keep clean.
