ASME B16.47 Series A&B Stainless Steel TH Flanges

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.

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.

The UNS S31254 Weld Neck Flange is preferred in welding applications. These flanges can hold the pipe in place during welding. The material has up to 1390 degrees Celsius melting point so that it could be used in high temperature and high pressure applications such as power generation, heat exchangers, boiler and petrochemical industrial applications.

Types of flanges include forged flanges, SS 304 threaded flanges and plate flanges. These different types are used in different types of applications such as oil and gas, petrochemical, petroleum, offshore oil drilling, domestic water lines, paper and pulp industries, 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 flange uses the flange as the interface between two sections of the pipe connection, rather than directly connecting the pipe. Its advantage is that compared with the straight pipe connection, the stainless steel flange is safer and more reliable, and the interface is more secure.

Stainless Steel 304 Flat Flange
Sometimes called a blanking flange; use to blank off pipelines, valves, and pumps, or as an inspection cover. Suitable for use with Schedule 40 or 80 stainless steel pipe, in applications with air, water, natural gas, and steam.

Where welding is required, the steel has the property of cracking as it cools. The high temperatures of the welding process cause what is known as “hot embrittlement” as the steel cools. This makes structures built with high carbon content steel more susceptible to damage due to the formation of cracks in areas where the metal is welded. 316l stainless steel alloy is used in a variety of applications as it is well suited to avoid weld corrosion. It can also withstand high temperatures and has a high melting point at about 2,500 degrees Fahrenheit or about 1,370 degrees Celsius. In addition to carbon, this alloy contains up to 2% manganese and up to 0.75% silicon.

The blind flanges are used to terminate a pipeline. Most of the times, a blind flange is used to permanently close a connection. Great Steel & Metals also produces Werkstoff No 1.4401 Stainless Steel Pipe Flanges in other shapes. The 316 material is more corrosion resistive and stronger than the ordinary 304 stainless steel.

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.

Another important role of stainless steel flange is that when a section of pipe does not need continuous connection, it needs to be partially blocked. At this time, the pipe can be easily sealed by using the flange.
