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]

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.

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.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

316L Pipe Fittings the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.

Incoloy 926 is more heat resistant than typical chrome-nickel stainless steel such as 304. The high nickel contained within gives it better oxidation resistance than the standard 18-8 type stainless steel.

F11 flanges are made of high-quality raw materials to perform well even in the harshest environments. This weight table is also available and products are manufactured based on it. Alloy steel F11 flange specification, the face type starts from flat face, raised face, ring joint, etc. These are used in applications where little resistance is required and general corrosion resistance is required.

Chromium oxide is created when chromium and steel react, which gives the corrosion resistant properties to stainless steel. This is one of the reasons stainless steel is great for sanitary valves and other sanitary items, because it does not corrode.

Steel pipes can be disintegrated on the basis of its application. Typical applications of steel pipes are in the area of water pipelines, industrial water lines, oil pipe lines, cross country pipe line, agriculture and irrigation pipes, tube lines for natural gas, chemical industries, automobile industry, construction industries and other purposes.

ASME B36.19M is the standard specification for stainless steel pipes, which specifies the dimensions, tolerance, and manufacturing requirements for both welded and seamless pipes.

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.

There are many different types of 316 stainless steel. Some common types are the L, F, N, and H variants. Each is slightly different and each serves a different purpose. “L” means 316L steel has less carbon than 316.

Another popular high-performing alloy, grade 304 stainless steel is a durable material in terms of tensile strength, durability, corrosion, and oxidation resistance. The melting point of stainless steel 304 is reached at temperatures ranging between 2,550 ¡ãF ¨C 2,650 ¡ãF (1399 ¡ãC ¨C 1454 ¡ãC). However, the closer grade 304 stainless steel reaches its melting point, the more tensile strength it loses.

Flanges have holes. Flanges and flanges are tightly connected by bolts and sealed by gaskets. Stainless steel is widely used in petroleum, chemical, nuclear power, food manufacturing, construction, shipbuilding, paper making, medicine and other industries.

SUS316L pipe has excellent forming and welding characteristics. It is easily braked or rolled into various parts for use in industry, construction and transportation.

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.
