Butt welding neck flange (WN)

Flange butt welding: welding neck flange is usually called "high flange hub". Its purpose is to transfer pipeline pressure, thereby reducing Frankie in high stress concentration. Welding neck flange butt welding is the best design those due to its inherent value of structural flange. However, the price is relatively high, because the production process is complex.

Thread (thread) flange: the threaded flange is used to connect. But the center of the product has a thread size corresponding to the pipe. The main advantage is that it can be assembled without welding.

Sliding flange: sliding flange has a lower hinge, because the pipe into the single flange welding. This is welded internally and externally provided with sufficient strength to prevent leakage. Sliding flange, are bored slightly larger diameter pipe matching. They are superior to the welding of the neck flange, due to the low initial cost, many users, but the final installation cost probably will not be compared, because the increase of the welding neck flange less.

Lap flange: the lap flange is in fact exactly the same as the sliding flange, unless it is in the hole and a radius of the flange race between. It is necessary to have the radius of the flange to receive the end of the lap joint. Usually, the mating flange and the overlapping stub are mated together with the assembly system.

The socket welding flange is a similar sliding flange, unless it has a hole and a counter bore size. The counter hole is matched with the pipe, so that the pipe is inserted into the flange similar to the sliding flange. The diameter of the smaller hole is the same as that of the ID for the same pipe. The limit is the built-in hole, as a shoulder sleeve for the pipe is stuck at the bottom. This eliminates any flow limitation in the use of socket welding flanges.
