Product Description:

A weld neck flange (also known as a high-hub flange and tapered hub flange

) is a type of flange. Weld Neck Flange is easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.

There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant. A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.

Such flanges are suitable for use in hostile environments that have extremes of temperature, pressure or other sources of stress. The resilience of this type of flange is achieved by sharing the environmental stress with the pipe with which it is welded. This type of flange has been used successfully at pressures up to 5,000 psi.

These flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radio-graphed for flaw detection.

Weld neck flange will be welded to a pipe or fitting with a single full penetration, V weld (Butt-weld).

Q:SolidWorks why can't the side flange be gray?
The other is modeled by a general model, and then converted into sheet metal using "insert bending.".
Q:About flange 5
Should mark "DN", is the nominal diameter of the code.Is the nominal diameter size after the roundness of the numerical repair to the mantissa, in order to simplify the mark.Germany, China ISO, nominal diameter are DN.
Q:How much is a bottle of Ma Falan produced in Switzerland?
Melphalan not produced in Switzerland, is a British GlaxoSmithKline Co (GlaxoSmithKline), referred to as GSK production, currently in the Hongkong market sales from Germany, Turkey India Taiwan (wake tumor) prices are more than HK $1000
Q:What is the reverse flange?
Positive and negative flanges are a pair of flanges. The reverse flange is another part of the matched flange, so as to avoid the connection between the two flanges of one and the other, because of the different rotation direction. The reverse flange is the standard flange. Standard is flange standard.
Q:How should we get to know the flange?
Flange forging forging casting iron and casting into a two GB standard and non standard to distinguish various standards, including some foreign standards.Such knowledge is not to be taught, but to be learned
Q:What's the flange body?
Flange connection or flange connection, is defined by the flange, gasket and bolt connection between the three sealing structure of the detachable connection as a combination of group pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange.
Q:Which flange is the front pipe case flange and the cylinder flange?
The front pipe case flange is the tube part, which is connected with the tube plate.A cylinder flange is a flange that is connected with a shell on the shell side, and no flange is used on the ordinary heat exchanger.
Q:DN200 how many screws are there in the weld flange?
We want to know the welding flange of DN200. The 16 kg pressure is 12 screw holes. 10 kg pressure welding flanges are 8 screw holes. Welding flange in the field, all you need is a welding flange pressure of 16 kg, so we just get you 16 kilograms of welded flange welding flange connection, but in your site is not correct, your connection welding flange is 10 kg pressure. It also shows that the connection you purchased is also a 10 kg pressure welded flange. In accordance with the requirements of the pipeline, please change your connections at any time or change the pressure in the pipe.
Q:Flange gasket RF600-6. What does this 6 mean?
6 indicates the pressure, 6 kg pressure flange
Q:Oil seal flange
Flange (flange) high pressure flange (SAE flange JBZQ 4187-97), also known as flange or flange. A part that connects the pipe to the pipe and is connected to the end of the pipe. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Fittings pipe (flanged) means a pipe with flanges (flanges or plates). It can be formed by casting and (figure not available), may also be threaded or welded together. The flange joint (flange, joint) consists of a pair of flanges, a gasket, and a number of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection. A flange connection is a detachable connection. The connecting parts can be divided into vessel flange and pipe flange. According to the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure.
