ASTM A182 F316L B16.5 Stainless Steel WN RF Forged Flange for Water Treatment

What is flange?

Flange (Flange), also called flange flange disc or flange. The flange is a part connected between the shaft and the shaft, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures. Pipe flange refers to the flange of the pipe distribution pipe in the pipeline device, used in the equipment refers to the import and export flange of the equipment. There are holes in the flange and bolts make the two flanges tightly connected. The flange is sealed with a gasket. Flanges are divided into threaded connection (thread connection) flanges, welded flanges and clamp flanges. Flanges are used in pairs, wire flanges can be used for low pressure pipes, and welded flanges for more than four kilograms of pressure. Put a gasket between the two flanges and fasten them with bolts. Different pressure flange thickness is different, they use different bolts. Pumps and valves, when connected with pipelines, the local parts of these equipment are also made into corresponding flange shapes, also known as flange connections. All the connecting parts that are connected by bolts around two planes and are closed at the same time are generally called "flanges", such as the connection of ventilation pipes, and this type of part can be called "flanged parts". But this connection is only a part of the equipment, such as the connection of the flange and the pump, it is not good to call the pump "flange parts". Relatively small such as valves, etc., can be called "flange parts".

What is WN (WELDING NECK) flange ?

Neck flat welded flange full name with neck flat welded steel pipe flange, is the steel pipe, pipe fittings, etc. into the flange through the fillet weld and equipment or pipe connection flange.

Advantages

Flat welded flange with neck is also a flat welded flange, because it has a short neck, which improves the strength of the flange and improves the bearing strength of the flange. So it can be used on higher pressure pipes.

Disadvantages

The cost is higher than that of flat welded flange, and it is easier to bump during transportation due to its shape characteristics.
