Stainless Steel Expanding Weld Neck Flange Manufatcurer in india

In some piping systems, the limitation of space does not permit larger sized pipes. This is seen in chemical processing plants, where there are limitations in the space of the area. Hence, the pipes used would be smaller, convenient to the setting of the factory. As the area changes, there could be a larger space available that can accommodate a larger sized pipe.

Expander Flange

Connecting pipes of both these sizes are possible using an Expander Flange. The function of both reducer and expander flanges are similar, that is, they connect two different sized pipes together in a piping system. The difference is that reducer flanges reduce the size of a pipe by connecting a larger one to a smaller sized pipe. Whereas the A350 LF2 Expander Flange connects a smaller pipe to a larger one. The benefit of using this device is that it works to be a convenient way to connect piping systems to valves, pumps, or different equipment. Since the ASME B16.5 Expander Flange is a component that is used to form connections, they are often exposed to corrosive chemicals, especially in processing industries. When any part in a system gets corroded, the replacement or repair costs of that particular part repeatedly will be expensive. Hence, many industries prefer using the expensive, yet efficient Stainless Steel Expander Flange. Although these flanges work out to be expensive in terms of the initial cost, over time, with regular maintenance, they would become an investment because they have good mechanical strength and are resilient to the effects of corrosion. Another alternative is to use a Carbon Steel Expanding Weld Neck Flange, which exhibits very high tensile strength, but lacks corrosion resistance properties, as offered by even the most basic stainless steel alloy.
