Forged Flanges

It is also called a butt weld flange because the flange neck has a reduced diameter and can be welded to smaller diameter pipes.

Flanges usually have a through hole and a square cut end (rather than the typical weld neck bevel). Generally, the bore diameter of the long weld neck is exactly the same as the actual nominal pipe size, but can be changed as needed. The overall length of the nozzle flange is also up to the end user, and the nozzle body can be modified to some pre-existing dimensions or custom sizes for additional reinforcement.

Butt weld flanges are available in a variety of materials. These materials must meet standards. Materials should also be of quality as specified by ASTM or ASME standards. However, the thickness and inner diameter of the flange will depend on the size of the pipe from which this butt weld flange is made.

The base of the neck connecting to the base of the flange is slightly rounded to alleviate the sudden vertical connection between the two parts of the flange and reinforce the idea of strengthening the one-piece structure.

When it comes to materials, carbon alloys are a common material for making these flanges because they are also resistant to extreme temperatures. It is available in ASTM A 181 and ASTM A 105 materials. Flanges are available in various grades such as ASME B16 47 ‘A’ series and ‘B’ series to meet customer and industry needs.

In addition to this material, butt weld flanges are also stainless steel. Flanges are made of ASTM A182, F304, 316L, 347H, 310S, ASME B16 5 and finished with duplex steel.
The duplex steel material of UNS S31803 is also in use. In addition to stainless steel, butt weld flanges are available in various other materials such as carbon alloys and nickel. Nickel alloy butt weld flanges are available for Inconel 600 and 625, Hastelloy C22, C276 and other such materials.

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 gradual transition of thickness from the bottom of the hub to the wall thickness of the butt weld provides significant reinforcement for the butt weld flange. The diameter of the butt weld flange matches the diameter of the pipe, reducing turbulence and erosion.

Such flanges are available in a wide variety of sizes, but welding flanges are expensive due to their long necks and the high cost of personnel to contact the WN flange with the pipe or fittings, but are preferred for high stress applications. The neck or hub transfers the stress to the pipe.

The thickness gradually transitions from the bottom of the hub to the wall thickness at the butt weld, providing an important reinforcement for the butt weld flange. The inner diameter of the butt weld flange matches the inner diameter of the pipe, reducing turbulence.

Butt weld flanges (also known as tall hub flanges and tapered hub flanges) are a type of flange. There are two designs. Regular types are used with pipes. The long version is not suitable for pipes and is used in processing plants. Butt weld flanges consist of a circular fitting with a protruding edge on its circumference.

These flanges are usually machined from forgings and are usually butt welded to the pipe. The rim has a series of drilled holes that allow the flange to be bolted to another flange.

This flange is suitable for harsh environments with extreme temperatures, pressures or other stressors. The elasticity of this flange is achieved by sharing environmental stresses with the pipe to which it is welded. This flange has been used successfully for pressures up to 5,000 psi.

Weld-on flanges are the most popular type of flanges with a weld bevel at the end of the neck extension. This type of flange is designed to be butt welded directly to the pipe to provide a superior and relatively natural form connection. In larger sizes and higher pressure ratings, this is pretty much the only type of flanged connection used. If only one style of drilled flange exists in modern applications, the weld neck flange will be your flange of choice.

The weld bevel is attached in a V-joint to the pipe end with a similar bevel, which allows for a uniform circular weld around the perimeter for a uniform transition. This allows gas or liquid within the piping assembly to flow through the flange connection with minimal restriction. Check the welded bevel connection after the welding procedure to ensure that the seal is uniform and free of abnormalities.

Another distinctive feature of butt weld flanges is the tapered hub. This type of connection provides a more gradual pressure distribution along the transition from the pipe to the bottom of the flange, helping to withstand some of the shock that occurs when used in higher pressure and higher temperature operating environments. Mechanical stress is limited considering the extra steel that transitions along the hub.

Butt weld flange, also known as tapered hub flange or high hub flange, is a flange that transfers stress to the pipe, ensuring that high stress concentrations at the bottom of the flange are reduced. There are two butt weld flange designs – the first is for rags, while the second, longer type cannot be used for pipes, but for processing plants.

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.
