Specification
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: Does the six angle flange bolt and the six angle bolt have the same meaning?
- Not the same meaning. The six head bolts are hexagonal in shape, and there is a gasket like structure between the head of the flange bolt and the thread!
- Q: I would like to ask this flange type in the end what is the shape, why is it called flange type?
- Flange typeFlange connection is an important connection way for pipeline constructionFlange connection is the two pipes, fittings or equipment, each first fixed on a flange on the flange between the two, and flange pad, fastened together with bolts to complete the connection. Some fittings and equipment have built flange, flange connection also belongs.
- Q: Where are metal flanges usually used?
- Electrostatic connecting line should be in accordance with the standards in Appendix H (informative) as shown in table H.1.Three. Specifications for design and construction of GB 50156-2002 gas station10.3.3 in * * hazardous areas of oil, liquefied petroleum gas and natural gas pipeline flange, hose ends the joint application of metal wire jumper. When the bolted flange connection not less than 5, in the non corrosive environment can be bridged.
- Q: what is the difference between this, and when what form of connection ah?
- The clamp is used for small caliber, and the flange is basically big bore and big pressure.
- Q: Inside and outside the plastic coated steel plastic composite pipe to flange connection
- In a shell of an electron tube, there are more than two electrode systems, each of which is independent of the electron flow to achieve its respective functions. This tube is called a composite tube. A composite tube is a combination of two or more transistors in accordance with a certain law, which is equivalent to a triode, and the compound tube is also called a Darlington tube.Composite pipes are divided into two categories: one is an ordinary composite pipe, and the inner no protection circuit; the middle and small power composite pipes like 2W are mostly such; and another kind of internal protective circuit is such a kind of high-power composite pipe. The following table shows the main characteristic parameters of the silicon NPN type high-power composite tube.
- Q: The connection between the air outlet and the air duct can straddle the flange
- The reason is: according to JGJ141-2004 "ventilation pipe construction technical regulations" requirements, different specifications of the wind pipe have the corresponding stiffness requirements, otherwise, must be reinforced. The tuyere destroys the integrity of the flange, which affects the stiffness of the duct.
- Q: One side is flat plate and side hubbed flange can be connected to it
- The same standards, the same pressure, the same caliber, with these three points can be connected
- Q: What is the function of the flange stub?!
- Different pressure flanges have different thicknesses and use different bolts. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. In the two plane in the vicinity of the use of bolted connections, and closed parts are generally referred to as "flange", such as ventilation pipe connection, this kind of parts can be called "flange parts."". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".
- Q: Can you check the anti - tumor drugs from Hongkong to the mainland?
- Hongkong can find peak pharmacy, you can mail back to the mainland, very convenient, and I hope to help you.
- Q: WoW World Mission, where is the French die cutter?
- First you go to the flange out from the portal. The past is Ireland, also ran for,Then you don't go down to the ground, go first to the pit, trigger the task, then you can find the litter in the range shown on the minimap, but the quantity and the density are not high, and you need to look for it patiently
