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.

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 .

These parts could be used in an as welded condition, despite not receiving annealing treatment. In many applications, the use of a UNS S31600 SS 316L Flange offers easy access to a worker for purposes including cleaning, inspection or even modification. Industries such as pharmaceuticals, which require sanitary alloys for the manufacture of their products prefer the use of ASTM A182 F316L Stainless Steel Pipe Flanges.

These stainless steel 304 threaded flanges are suitable for welding as it has a lower carbon content than 301 to 303 series alloys to avoid carbide precipitation in welding applications. Equipment in the chemical, food, paper, mining, pharmaceutical and petroleum industries often includes stainless steel 304 butt weld flanges. The addition of molybdenum and a slightly higher nickel content make stainless steel 304 blind flanges suitable for construction applications in harsh environments, from contaminated Marine environment to areas with temperatures below zero.

Applications and Materials
Normalizing is mainly used for normalizing the structure of carbon steel and low alloy steel after forging, hot rolling or casting. The hardness obtained after normalizing depends on the steel dimensional analysis and the cooling rate used (approximately 100-250 HB).

The 304L Stainless Steel Flange Pressure Ratings differ ranging from 150 to 2500 and PN6 through PN64. The temperature tolerance is also high for these flanges and they can operate at up to 870 degrees Celsius.

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 ASME B16.47 standard includes MSS SP-44: Steel Pipe Flanges and API 605: Carbon Steel Large Diameter Flanges. Therefore, MSS SP44 flanges are equivalent to A series flanges and API 605 flanges are equivalent to B series flanges. The materials covered by this standard are the same as those in ASME/ANSI B16.5, with the exception of nickel alloys. They also have the same pressure temperature rating as B16.5 flanges.

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.

SS 304 flange price list depends on each piece the customer wants to buy, eg ASTM A105 is between RS 180/piece to RS 350/piece, while ASTM A182 is between RS 100/piece to RS 300/piece.

As there are many mechanical properties of stainless steel 304 plate flanges but some of them are discussed, such as density, melting points, tensile strength and many more.

SS 316/316L Flanges are one of the most commonly sought after products in the industry. These SS Flanges are known for their properties such as better corrosion resistance, pitting and crevice corrosion when compared to type 304.

Stainless Steel 316 is an austenitic stainless grade with 4% molybdenum in its composition. The content of chromium, nickel and molybdenum makes stainless steel 316 stronger, corrosion resistant and ductile.

Stainless Steel 304 Flanges are made up of an austenitic stainless steel that has 18% chromium and 8% nickel in the composition. This composition makes the flanges strong and corrosion resistant for general corrosive services.

These SS 304 flanges are resistant to a wide range of atmospheric environments and aggressive media. Our 304 stainless steel lap flanges are used to connect pipes, valves, pumps and other equipment to form piping systems.

Stainless Steel 316L Flange is used to terminate the end of a piping system. The Stainless Steel 316L blind flange is basically a flange that does not have a hub or a bored center. Blind flanges have the face thickness of a flange, a matching face type, and similar bolting pattern. Stainless Steel 316L Blind flanges can also be used to seal a nozzle opening on a pressure vessel.

For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.

In industrial processes where fluid and gas flow rates need to be measured accurately, orifice flanges play a critical role. The 304 orifice flange is a type of orifice flange that is manufactured using the ASTM A182 standard. A182 304 UNS S30400 Stainless Steel Orifice Flange is made from an austenitic stainless steel, and is widely used in a variety of industries due to its excellent corrosion-resistant properties.

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]

Reducing flanges change pipe size without adding additional fittings. The reduction in flanges is always abrupt compared to what can be achieved with concentric butt welded reducers. Reducer flanges are usually available as threaded reducer flanges or reducer flange slides. A 6″ x 4″ reducer slip on a flange will have the flange dimensions (outside diameter, bolt circle diameter) of a 6″ flange, but have the holes of a 4″ flange. This allows it to mate with 6″ pipe via a flange connection, but connect 4″ pipe instead.

All our Stainless Steel 317 Flanges conform to relevant material and dimensional specifications and can be supplied complete with material certificates to EN 10204 3.1.

The most popular material grades are made of carbon steel. HT PIPE not only offers carbon steel pipe flanges and flange fittings, but we also offer stainless steel flanges for a variety of projects. Plate flanges can be ordered for waterworks and petrochemical applications. Bar flanges and forged gauge flanges can also be manufactured to the dimensions in our catalog.

Since higher pressure ratings almost exclusively require this type of flange connection, butt weld flanges are usually made with ring joint faces (also known as RTJ faces). This sealing surface allows a metal gasket to be crushed between the grooves of the two connecting flanges to create an excellent seal and complement the high-strength welded bevel connection to the pressurized piping assembly. RTJ weld necks with metal spacer connections are the primary choice for critical applications.

Stainless steel flange is also called flange plate. Flanges are the parts that connect pipes to each other and are connected to pipe ends. Flange connection or flange joint refers to the detachable connection of a group of combined sealing structures connected by flanges, gaskets and bolts.
