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:To set the price
- I checked it on the InternetThere are several kinds of this one you sayThe cheapest is more than 100, and the most expensive is five hundred
- Q:What does the Rc-RF in the flange stand for? What do they stand for?
- Rc is the threaded flange,The internal teeth are 55 degrees of degree of PT teeth, the standard of the teeth, the Japanese standard is JIS B0203, the European standard is ISO, the 7-1 German standard is DIN 2999,RF, as mentioned upstairs, means that the sealing surface is bulging
- Q:Can you check the anti - tumor drugs from Hongkong to the mainland?
- You shipped back, no one dared to use it for you? Drugs used by medical institutions should be approved by the state, and if approved by the SFDA, then there is no need to take them from Hongkong. If there is no domestic, it is not yet approved to enter the Chinese market, so that the hospital did not dare to use you, earn money, do not make money is a small matter, checked to the hospital and the doctor on the end. Then, can I use it secretly? General drugs, especially antineoplastic drugs have side effects, and sometimes have serious adverse reactions, once there, the hospital can not be processed in accordance with the formal process, when the patient or the patient himself. So, you have to use it, it's more reliable to send the patient to Hongkong.
- 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 do butt welding flanges WN300-150, RF, Sch40 mean?
- WN said neck flange; 300 said flange nominal diameter 300mm, the 150 refers to the nominal pressure flange is 150LB (pounds) system will usually only America in pounds nominal pressure; RF said flange sealing surface for ordinary raised face seal, SCH40 pipe wall thickness grade with neck, usually with a welding neck flange and butt welding ring flanges complete specifications are required to fill in the pipe wall thickness.
- Q:Flange WN50 (B) -25 RF S=6 specific points
- WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness
- Q:What are the advantages of a flanged plunger valve?
- Advantages of flanged plunger valves:In 1, the flange valve in the plunger and the seal ring used between the interference fit, by adjusting the gland in the flange bolts, the lateral force and the valve body sealing ring compression product in cylindrical hole surface and the plunger seal, thus ensuring the sealing performance of the valve, to prevent the internal leakage, and valve opening moments small, can realize the rapid opening and closing the valve;2, because the sealing ring adopts the strong rebound resistance and the abrasion resistance of the non-toxic new sealing material, has a long-term high temperature, high pressure without losing elasticity, so the sealing performance is reliable and durable.Extension of knowledge point:Flange plunger valve by the valve body, valve cover, stem, plunger, hole frame, ring, hand wheel and other components. When the hand wheel rotates, the plunger is driven to move up and down in the middle of the hole frame through the valve stem to complete the opening and closing function of the valve. Currently, flanged valves are widely used in petroleum, chemical, chemical, gas, gas, liquefied petroleum gas, HVAC and general industries
- Q:Is it a flange or a Flange?
- Flanges (Flange), also called flanges, flanges, or flanges. The flange is a connecting part between the shaft and the shaft, 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. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp. Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. 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. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". 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:What is the function of the flange stub?!
- Flange is a kind of discoid parts, which is the most common in pipeline engineering. The edge has bolted mechanical structures, such as pipe joints, which can be bolted if flanges are attached to the flange. The flange cap is the flange of the cap and is bolted to the flange. Flanges are used in pairs.
- Q:What's the thickness tolerance of neck flange?
- Specification for JB/T74-1994 pipe flangesSH3406-1996 steel pipe flanges for petrochemical industrySpecification for GB/T17241.7-1998 cast iron pipe flanges
