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 .

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.

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.

For stainless steel flange, appropriate stability elements such as Ti, Nb and Mo are added to improve corrosion resistance and weldability. The weldability is better than that of chrome stainless steel flange.

It is an austenitic stainless steel alloy with high nickel (24%), chromium (22%), molybdenum (6%), and nitrogen (0.18%) content and is commonly known as superaustenitic stainless steel (alloys such as 254 SMO (UNS?S31254) and 904L (UNS?N08904) also fall under the superaustenitic designation) while 2205 (UNS S32305/ S31803) and 2507 (UNS S32750) are duplex and super duplex stainless steel, respectively.

ASME SA 182 AS Forged Pipe Flanges are forged from a single piece of raw material for good strength. Some applications need to end pipes instead of connecting more pipes. A182 Alloy Steel Blind Flanges are used for permanent or temporary closure of pipelines. Flanges can be welded or bolted.

At moderate temperatures, SS 304 flanges can also provide good performance in aggressive solutions, especially those that do not contain chlorides or fluorides. While Grade 304 performs well in fresh water applications with low chloride levels (i.e. less than 100 parts per million), exposure of the alloy to higher chloride levels makes UNS S30400 304 stainless steel flanges susceptible to crevice and pitting corrosion Impact.

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.

Long butt weld flanges, also known as nozzle flanges or “long neck” flanges, are designed for the pressure vessel and tank manufacturing industries. They are usually made in one piece and are designed to replace standard weld neck and pipe weld combinations. The lack of the necessary welded connections is a defining characteristic of this flange style.

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]

The standards vary from B16.5, B16.47 and in different series A and B. There are different types based on the production such as the ASME SA182 grade 316TI Weld neck flange. The weld neck flanges are useful because of the neck welded onto the flanges, they allow for better grip. The different standards such as DIN 1.4571 Flange determine the size, diameter and wall thickness of the flanges.

Molybdenum in Incoloy 925 Slip On Flanges aids resistance to pitting and crevice corrosion whilst Chromium offers resistance to oxidizing environments.

Blind flanges can be permanently welded to the pipe or bolted for temporary closure. ss 304 flange slips are easy to install on seamless pipes. The slips on the flanges can also be adjusted for the connection position as they allow the pipe to slide over them.

However, it should be limited to 927 degrees Celsius and should not go below that. The ideal temperature for hot working stainless steel floor flanges is between 1149¡ãC – 1260¡ãC. For optimum corrosion resistance, stainless steel blind flanges require post-work annealing. These Astm A182 F316 blind flanges are also available in different pressure classes. Werkstoff No 1.4301 lap flanges are used in the chemical, energy, power, medical and petroleum industries.
