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.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

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.

Austenitic stainless steels are susceptible to stress corrosion cracking (SCC) in halide environments. Although type 316 alloys are more resistant to SCC than 18Cr-8 Ni alloys due to their molybdenum content, they are still susceptible. Conditions that produce SCC are: (1) the presence of halide ions (usually chloride ions), (2) residual tensile stress, and (3) temperatures in excess of about 120¡ãF (49¡ãC).

A wide variety of stainless steel flanges are all available at HT PIPE, including weld necks, slip-ons, threaded, socket weld, lap joints, blinds, and hub blinds.

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.

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]

To recover the inherent corrosion resistance of stainless steel castings. The corrosion resistance of stainless steel decreases after investment casting. The corrosion resistance of stainless steel castings recovered to the optimum state after solution treatment.

Stainless steel pipes have good intergranular corrosion resistance, excellent corrosion resistance and cold working and stamping properties, and can be used as heat-resistant stainless steel. At the same time, the mechanical properties of the steel are still good at -180¡æ. In the solid solution state, the plasticity, toughness and cold workability of steel have corrosion resistance in oxidizing acid, atmosphere, water and other media. Therefore, 304 stainless steel is the steel with the largest output and usage and the most widely used steel.
