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: Is AS2129 TABLE D only flat flange? What are the criteria for TABLE D? The more detailed, the better.: AS 2129-2000, Flanges, for, pipes, valves, and, fittings.You download it and see it, and American Standard Astm B16,9 standard JIS B2220-2004 European standard EN 1092-1-2005 set is basically the same, butt welding, welding, blind plate has more flat out. Just without thread and socket flange.

Q: 60 seamless steel tubes with 50 flanges, right?: The problem should be this, 60mm seamless steel tubes with DN50 flanges, right?Normally; diameter seamless pipe DN50 welding flange is 57mm, if it is seamless and DN50 matched flange 60mm, seamless processing thread, flange hole machining internal thread, so just.In the form of welding, the DN50 flanges need to be machined and they are also available.

Q: SB 1379-NP15 which flange standard is the flange diameter, pitch, thickness, screw hole number and diameter?: Several systems of international standards for pipe flanges1, flange connection or flange connection, is defined by the flange, gasket and bolt three are connected as a group of combined sealing structure can be folded connecting pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange.

Q: What is the flange? What are its application areas and principles?: Flanges (Flange), also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures.Flanges are widely used in construction, power generation, machinery and many other fields, and their main functions are as follows:1. Connect the pipe and keep the sealing performance of the pipeline.2, to facilitate the replacement of a section of the pipeline.3, easy to disassemble check the pipeline.4, to facilitate the closure of a section of the pipeline.Classification of flanges1. carbon steel, cast steel, alloy steel, stainless steel, copper and aluminum alloy are classified by material2., the production method can be divided into forging flange, casting flange, welding flange and so on.3. makes the standard can be divided into national standard (Ministry of chemical industry standard, standard oil, electricity standard), American Standard (ASTM), German standard (DIN), Japanese standard (JB).
