Orifice flanges are widely used in conjunction with orifice meters for measuring the rate of flow of liquids and gases. They are basically the same as standard welding neck and slip on flanges except the provision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack...
Swivel flanges are becoming more and more popular now, it includes a heavy forged welding hub and a rotating forged ring that serves as a mating flange to a Weld Neck.These versatile flanges are utilized in many applications and are used extensively in offshore piping where they solve the issues associated with the...
Blind flanges are used to blank off the ends of piping, valves and pressure vessel opening. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed of all flange types. Blind Flange is also used in the flange of the import and export of...
Figure 8 spectacle blind flange
Spectacle and line blind flanges are similar to a blind flange but different because they fit between two flanges. Spectacle blind gets their name from similarity to pair or eye glasses. Once side of spectacle blind flanges is fully closed for complete flow shuts off, whereas the other end is open for full flow. In...
Black painting flange looks more seriously than other colors, it is needed in the markets of south east and mild east of Asia. Slip on weld fange can be slid onto a pipe and then welded in place. It is made of carbon steel, alloy steel, and stainless steel. The industrial processes come into die forging, and...
Threaded flanges are confined to special applications. Their chief merit lies in the fact that they can be assembled without welding this explains their use in extremely high pressure services, particularly at or near atmospheric temperature, where alloy steel is essential for strength and where the necessary post...
B16.5 Aluminum material flange
A flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework systems. It is the machinery, petroleum, chemical, water, electricity, shipbuilding sectors piping systems and devices most widely used pipe fittings. Flange is a part of the piping system used inside or outside the...
Welding neck flange is the correct terminology to be used as standard. In the industry welding neck flanges are commonly refered to as weld neck flange or WN flange. The welding neck flange consists of a tapered hub which is secured to the pipe by a full penetration butt weld. because of the additional reinforcement...
Welding neck flange are distinguished from other types by their long tapered hub and gentle transition of thickness in the region of the butt weld joining them to the pipe. The long tapered hub provides an important reinforcement of the flange proper from the standpoint of strength and resistance to dishing. The...
Long weld neck is that the neck height is higher, which improves the rigidity and bearing capacity of the flange. Compared with butt welding flanges, the welding workload is large, the welding rod consumption is high, and it cannot withstand high temperature and pressure, repeated bending and temperature fluctuations,...
