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 .

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.

Incoloy 926 is more heat resistant than typical chrome-nickel stainless steel such as 304. The high nickel contained within gives it better oxidation resistance than the standard 18-8 type stainless steel.

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.

Similar to most low carbon containing stainless steel alloys grade 316L is less susceptible to getting corroded by means of intergranular corrosion.

Alloy 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). The alloy is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. Alloy 309 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced.

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 flange not only saves space and weight, but also ensures that the joint will not leak and has good sealing performance. The compact flange size is reduced because the diameter of the seal is reduced, which will reduce the section of the sealing surface.

Commonly used to blank off pipelines, valves, and pumps, or as an inspection cover, this GRAINGER APPROVED blind flange allows you to bolt 2 flanges together with a gasket to form a tight seal that still eases access to the piping system. This model is sometimes referred to as ¡°blanking flange¡± and is for use with air, water, oil, natural gas, or steam.

Due to greater chromium content and average nickel, it becomes sulfidation resistant. It is used at the cementing, thermal cycling, oxidizing, and nitriding applications.

Exposure of conventional austenitic alloys to this solution will often cause cracks under pressure as chloride ions deposit on the flange walls. Because ASTM A182 F51 pipe flanges contain equal proportions of austenite and ferrite, they have excellent SCC resistance.

The material has 19% chromium, 17% nickel, 6% molybdenum with carbon, manganese, silicon, copper, sulfur and sulfur in it.

The ASME SA182 SS 310 Pipe Flanges can come in ASTM A182 or A240 specifications and ANSI, ASME, BS, DIN and EN standards. The dimensions range from 1/2 inches to 48 inches but there are different standards for special purpose flanges and their dimensions as well.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

Typical applications for steel include: food preparation equipment, laboratory equipment, chemical containers for transportation, springs, heat exchangers, mining screens, coastal building paneling, railings, trim, marine fittings, quarrying and water filtration. One of the main differences between 316l stainless steel and 316 stainless steel is that the carbon content of the former is as high as 0.03%, and the carbon content of the latter is as high as 0.08%. These differences give them different properties. Let’s learn more about the 316l stainless steel alloy.

SMO 254 Flanges is readily available for applications in the industrial, architectural, and transportation fields.

HT PIPE is one of the leading suppliers and traders of SS 304 flanges which are nickel plated to maintain austenitic composition at lower temperatures. Stainless Steel 304 Slip Flanges are austenitic stainless steel with better corrosion resistance than Stainless Steel 317.

A bs 4504 316l plate flange is a flat, circular disk that is welded onto the end of a pipe and allows it to be bolted to another pipe. Typically used in fuel and water pipelines, the two plate flanges will be bolted together with a gasket in between them. The plate flange will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.

ASTM A182 F310s Flange combining excellent high temperature properties with good ductility and weldability, is designed for high temperature service. It resists oxidation in continuous service at temperatures up to 1150¡ãC provided reducing sulphur gases are not present.

These flange styles are also known as “Straight Hub Weld Flanges” according to ASME B16.5 subsection 2.8 and are given minimal detail in the governing code. This is because long weld necks are selected on a per application basis according to the specific engineering requirements of a given tank or pressure vessel. The working pressure, temperature and medium of the vessel are all key factors in determining which type of long butt weld flange connection you need.

RFWN flanges (raised face weld neck flanges) are one of the most commonly used flanges in the plumbing industry. Their long tapered hub matches the wall thickness (hole) of the pipe and is easy to identify.

Weld butt flanges and long butt weld flanges provide reinforcement in applications requiring high pressure and in extreme low and high pressure situations. It also helps address low cycle fatigue caused by otherwise variable force linear expansion.
