317L Flat Face Threaded Dn150 Welding A Weld Neck Flange To Pipe

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.

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.

The composition of stainless steel 304L flanges contains carbon, nickel, silicon, nitrogen, sulfur, manganese, phosphorus and chromium. 304L is available in different grades depending on the carbon content.

The material 304 is strong with 515MPa minimum tensile strength and 205MPa minimum yield strength. The material is also corrosion resistant to most atmospheric conditions.

The SS DIN 1.4841 Forged Flanges can come in different pressure classes of PN6 through PN64 and 150 through 2500 pressure ratings. There are different types such as slip on flanges, weld neck flanges, socket weld flanges and the blind flanges. Each of them is used for a specific need.

Spade Flange and Spacers Ring are normally referred to as Line Blinds. which has the similar function as a Spectacle Blind . The Spade or Spacer is fitted in the line between two flanges and is bolted in place. The Spacer is used when the line is required open and the Paddle Blind or Spade is installed when the line is required blocked or closed

SS 347 flanges are used at cryogenic temperatures as well as high temperatures and at high wear and tear applications

This specification includes flanges for pressure vessel grade applications. The material has good strength and general corrosion resistance, high operating temperature. The minimum yield strength of 304 stainless steel flange is 215MPa, and the minimum tensile strength is 505MPa.

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]

Butt weld ends shall be machined in accordance with ASME B16.25.

SS 316/316L flanges can be fabricated from ASTM A182 F316 or F316L forgings, ASTM A351 CF8M or CF3M castings, and ASTM A240 316 or 316L plates per ASME B16.5 and ASME B16.47.

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.

The Stainless Steel 317L RTJ Flange has two rings as a pair and is connected to the pipes via welding. Just like the socket weld flanges, the SS 317/ 317L Weld Neck Flange has a neck welded onto it for better connection.

Stainless Steel UNS S31254 Flanges will require greater force than used in other austenitic stainless steels. Grade WNR 1.4547 Flanges is often used in Pulp and Paper Industry, such as for bleach plant, vats, drums, press rolls, piping, etc. In new construction,

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.

A reducing flange is a special type of flange that proves beneficial when used in projects that require fitting two pipes of different sizes together. There are many different types of reducing flanges, some of which are as follows – Weld Neck Reducers, Drop-in ASME B16.5 Reducers and Threaded Reducers.

The SMO 254 Spectacle Blind Flange is considerably much stronger as compared to the standard or conventional austenitic grade alloys. The tensile strength of the Alloy 254 SMO is nearly two times that of grade 300 series stainless steel.

normalized basis
Normalizing removes impurities from steel and increases its strength and hardness. This is achieved by changing the size of the grains to make them more uniform throughout the steel sheet. The steel is first heated to a specific temperature and then cooled by air.

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.

AISI 304H is readily formed and fabricated through a full range of cold working operations.

Incoloy 925 flange is often used for marine and pump shafts or high-strength piping systems.

254 SMO is a high-alloy austenitic stainless steel developed for use in aggressive chloride-bearing media or seawater applications. The 254 SMO is characterised by its high chromium content, this is further complemented by its molybdenum and nitrogen content which gives 254 SMO excellent resistance to pitting and crevice corrosion. Since these oil storage tanks are located in the Arabian Gulf (saline conditions) the use of this material was an optimal solution for the environment. In addition to this, the coating of the flanges was also specially selected due to its protective qualities.
