Material StandardANSI B16.5

This group of Welding Neck Flange is designed with a hub on the backside tapering to a diameter that will match the pipe to which it will be welded. These flanges are bored to match the inside diameter of the mating pipe so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. Welding neck flanges are preferred for use in severe service applications involving high pressure, sub-zero and/or elevated temperatures. They also provide excellent stress distribution through the tapered hub and are easily radio graphed for flaw detection.

A Slip-On Flange is bored so that it does indeed slip onto the pipe so that the end of the pipe is just inside the flange a fraction of an inch from the flange face. The pipe end has been cut square. The flange bolt holes are aligned and the flange face squared to the pipe. Then a fillet weld is run around that end of the pipe to fuse it to the inside of the bore of the flange. Another fillet weld is run around the back end of the flange hub fusing it to the outside of the pipe. This is the most common welding flange. Before the final full fillet welds are made, temporary tack welds are made until alignment is assured. These tacks are easy to cut out so a correction can be made.

A popular category of pipe flange is the Blind Flange. A blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.

The Lap Joint Flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face. This radius is necessary to have the flange accommodate a lap joint stub end are mated together in an assembly system.

Advantages:

  • The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face
  • This radius is necessary to have the flange accommodate a lap joint stub end are mated together in an assembly system

A Plate Flange is a flat, circular disk that is welded onto the end of a pipe and allows it to be bolted to another pipe. Typically used in fuel and water pipelines, the two flange plates will be bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.

Socket Welding Flange, a popular type of pipe flange, was initially developed for use on small-sized high- pressure piping. The fabrication of this type of flange is similar to that of a slip-on flange. However, the internal pocket of a socket weld flange allows for a smooth bore and better fluid flow. When provided with an internal weld, the static strength of this flange is equal to slip-on flange, but the fatigue strength is 50% greater than double welding slip-on flanges. Smooth bore conditions in such a flange can easily be attained without having to bevel the flange face and, after welding, to reface the socket weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process piping.
