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:Can the equipment and pipe be directly connected between the pipe and the pipe, flange or welding?
1, generally not directly connected, or wire, or flange connection.2, flange (Flange), also known as flange, flange plate or edge. 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. 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:Inside and outside the plastic coated steel plastic composite pipe to flange connection
1, press groove with groove machine2, clamps one, the short pipe flange one, carries on the connection3, after the connection, corresponding to the valve flange is OK, remember to see the number of flange holes in advance.
Q:What is the output flange? What's the function?
Flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together, completed the connection. Some pipe fittings and equipment have their own flange, but also belong to flange connection.Flange, threaded connection (wire), flange and welding flange.
Q:What is the silk flange?
Generally refers to the pipe, pipe connections, the commonly used way is divided into: silk and flange two. The screw thread is a screw thread connection; the flange is to weld the two end of the connecting pipe on the convex ring, drill a few holes, and penetrate the bolt in the hole to connect.
Q:The soul of darkness, how about the souls on the slopes beside the cursed frogs outside 3 flanges?
4. magic, bow and arrow can only serve as an auxiliary, can not serve as the main force. 5. opening gifts suggest choosing a flame metamorphic gem, the early game (Wangcheng, outer walls and undead streets), 80%-90%'s enemies, weak fire. 6. sword God and God was badly cut chicken. Case: a main broadcast take the sword in the tomb of the dungeon play skeletons, a multi segment, the first under a huge damage, directly to the skull behind the play apart, waving empty, only the skeleton together again. Look at the real egg pain, case two: the 2 generation, giant sword and big chicken legs, when the enemy moves, you can directly put the enemy lying prone. But in this seat, the little monster in the move when the giant sword shot, often against the chop. I suspect that the 3 generation has "hard and direct protection", which is a continuous attack on the same target, and the target will be continuously reduced, which is a bad news for the weapon. Think of the 3 generation of giant weapons compared to the 2 generation, moves and withdrawal are slow. 7. most BOSS do not have "routines" for opportunistic. For example, the 2 generation, many non DLC original BOSS, can be raised to shield the back of the stream, "Lai die", there are several UP with this habit against the three generation of BOSS and small soldier, the result of crazy suffering. Even the ordinary Knight mobs are in your shield around him, he will use a Shield Slam your shield, causing damage prevention, and anti kill!!! BOSS war, against the 2 generation of giant BOSS has a formula called "crotch person", the "best student change, otherwise it will crazy. More than 8. UP anchors said in an interview that the 3 generation of "anti - roll decisions" is the most difficult of all generations
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 flange? What are its application areas and principles?
The flange is used for connecting and sealing the head of the container and the cylinder. The container can be disassembled from flange and convenient for maintenance.
Q:Are couplers and flanges the same thing for optical fiber? Five
Fiber coupler is removable between the optical fiber and optical fiber (active) connection device, it is the two fiber surface precision docking, so that the optical output of the light energy to maximize the coupling to the receiving optical fiber, and the effect of intervention on the system caused by the optical link to minimize the.
Q:The Ministry of chemical industry hubbed flange size PN10 and PN16 are basically the same,
PN is the pressure grade, PN10 indicates pressure of 10 kg, and PN16 indicates 16 kg of pressure.No, you can use PN16 as PN10 instead of PN10 as PN16You write very clearly,
Q:Can you check the anti - tumor drugs from Hongkong to the mainland?
This can be mailed, generally Hongkong post can express. Even if the charge is high, one point one small packages will require 160 Hong Kong dollars. Prior to help friends in Hongkong, Walter bought the house. I hope my answer can help you, but also hope to adopt
