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.

Stainless steel flanges will not be corroded, pitted, rusted and easy to wear. Stainless steel is one of the metal materials with the highest strength for building.

Featuring 304 stainless steel for very good corrosion resistance, this GRAINGER APPROVED weld neck flange can be attached to a system via a circumferential weld at the neck. The welded area can be easily examined by radiography. Matched pipe and flange bore reduces turbulence and erosion inside the pipeline. Flange is excellent for use in your critical applications and is ideal for use with air, water, oil, natural gas, and steam.

Weld flange holes are machined to match the ID of the pipe or fitting. This creates a smooth transition between weld neck flanges and prevents turbulence at the weld neck. Therefore, it is important to specify a piping plan when purchasing butt weld flanges. Butt weld flanges are welded to the pipe with a full penetration weld and provide excellent stress distribution through the tapered neck. In critical applications, welds are also often radiographically or UT inspected.

310SS flanges also have good resistance to sulfidation and other forms of hot corrosion. Although primarily known for its high temperature properties, 310 stainless steel also provides excellent performance at cryogenic temperatures.

Butt weld flanges are flanges designed to be connected to piping systems by butt welding. There are many specifications of this flange. Butt weld flanges are expensive because of their longer necks and high personnel costs for WN flanges in contact with pipes or fittings, but are preferred for high stress applications. The neck or hub transfers the stress to the pipe.

The function of stainless steel flange is actually to connect the pipe end with the pipe end. There are flange eyelets on the flange edge, and the stainless steel bolts make the two flanges to be matched tightly. When connecting, gaskets, PTFE gaskets, metal gaskets, silicon gaskets, etc. are required between flanges for sealing.

Incoloy 925 flange is often used for down-hole and surface gas-well because of their excellent resistance to sulfide stress cracking and stress-corrosion cracking in ¡°sour¡± (H2S containing) crude oil and natural gas.

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).

It is also a cost-effective alternative to less expensive alloys, such as Type 316, that do not have the strength or corrosion resistance required to minimize life cycle costs in certain applications.

316L is best known among manufacturers for crack resistance after the welding process is complete. This makes the 316L the first choice for manufacturers looking to build metal structures for industrial applications.

Long weld neck flanges (also known as LWN) have an extended neck that acts as a boring extension and is longer than a standard weld neck flange. Welded neck flanges are easy to recognize because they have a long tapered hub that reduces its size from the pipe to the fitting.

254 SMO Flanges, which is used in varied industrial and commercial sectors and is quality assured. SMO 254 Slip On Flanges (UNS S31254) is often used in Flue gas desulfurization scrubbers, Components used in petroleum production, Food processing equipment and more.

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]

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. In the food and catering industry, stainless steel is used to manufacture kitchen accessories, cookware, and cutlery. Utensils such as knives are made using less ductile grades of stainless steel. The more ductile grades are used to make grills, cookers, saucepans, and sinks.

Grade SS 304L is also known as 18-8 steel, mainly due to the composition of 18% Chromium and 8% Nickel, responsible for inhibiting corrosion caused due to acids in the food and beverage industry

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.

In most cases, the corrosion resistance of our stainless steel 316 butt weld flanges is about the same in most corrosive environments.

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.

Stainless Steel 310 Flanges are made up of a stainless steel grade that has high amounts of nickel and chromium. It is a chromium nickel alloy with 24% chromium and 19% nickel in the composition.

There are no gaps or grooves that could lead to crevice corrosion. Conical necks are also known as “nozzle necks” or more commonly “high hubs”. Although expensive, butt weld flanges are the best designed butt weld flanges because the long tapered hub provides excellent strength and dent 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.
