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.

Flange is the parts which connects two pipe ends, flange connection is defined by the flange, gasket and bolt three are connected as a group of combined sealing structure of the detachable connection. The gasket is added between the two flanges and then fastened by bolts. Different pressure flange, thickness is different, and the bolts they use are different, when pump and valve connect with pipe, the parts of the equipment are also made of the corresponding flange shape, also known as flange connection, usually closured bolted connection parts are also known as flanges, such as the connection of ventilation pipe, this kind of parts can be called “flange type part”, but this connection is only part of a device, such as the connection between flange and water pump, it’s not inapposite to call water pump as flange type parts,but relative small valve,it can be called as flange type parts .

Although molybdenum is a good element, excessive use of it may reduce the creep ductility of Gr F11 plate flanges. Graphitization and decomposition of iron carbide may occur when the temperature exceeds 500 degrees Celsius. Chromium has been added to SA A182 F11 alloy steel CL.2 forged pipe flanges to prevent creep ductility reduction and graphitization. In addition, the added chromium also provides oxidation resistance.

Because the Incoloy 925 Weld Neck Flanges offers excellent corrosion resistance in both oxidizing and reducing environments, the grade has proven useful in many ¡°sour¡± applications in oil and natural gas applications.

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.

These threaded flanges are suitable for welding as they have a carbon content lower than the 301 to 303 permutation, which avoids carbide precipitation in welding applications. Stainless steel butt weld flanges are often used for gears in composite, nutritional, paper, mining, pharmaceutical and petroleum companies. The expansion of molybdenum and the slightly higher nickel content make stainless steel 304 blind flanges suitable for structural applications in harsh environments, from dirty marine environments to sub-zero temperatures.

It is applicable to food production equipment, Xitong chemical equipment, nuclear energy, etc.

The A182 F316L Rtj reducing flange is a special type that has two halves as rings. The rings are welded together with pipes of the same size, then the two halves are fitted together for maximum hold. SS reducing flanges are available in different pressure classes such as class 1500 to class 600.

A spectacle flange is a specialty flange made of two metal discs attached in the middle by a small section of steel. Spectable flanges get their name because they look like a pair of reading glasses, or spectacles.

While the chemistry of Stainless Steel 304L Flanges is similar to grade 304, there are some changes done to its chemical composition. The modification in the chemistry of grade 304L improves its properties like weldability.

Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure “Tappings”, mostly on 2 sides, directly opposite each other, are machined into the orifice flange.

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]

Though 310 is ideal for high temperature use, it should not be exposed to the severe thermal shock of repeated liquid quenching or where aqueous corrosive contaminants are present.

Alloy 317 flange is an austenitic chromium-nickel stainless steel with excellent corrosion resistance. The high molybdenum content of ASME SA182 SS 317 flanges contributes to the grade’s excellent pitting resistance.

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.

Incoloy 926 is also resistant to chloride stress corrosion, with good corrosion resistance in both oxidizing and reducing media.

The flange itself is not welded, but the short pipe end is inserted/slid over the flange and welded to the pipe. This arrangement facilitates flange alignment where misalignment can be an issue. In a lap flange, the flange itself is not in contact with the fluid. The stub end is the part that is welded to the pipe and is in contact with the fluid.
