Reliable ASME B16.5 Class 2500 Flange Manufacturers In India, Accept All Large & Small EN 1092-2 PN16 2500# Slip On Flange Orders.
One of the main functions of flanges is maintaining, inspecting, and repairing the whole piping system. ASME B16.5 Class 2500 Flange too have the same function, and they are available in different types like ANSI B16.5 Class 2500 RTJ Blind Flange, socket weld, weld neck, and many more. Each type is constructed differently, and they can withstand various pressure-temperature capacities depending on their material type and pressure ratings.
We manufacture PN16 2500# Slip On Flange, which looks like a ring and places over the end of the pipe. They are mainly used for low-pressure fluids that have little chance of leakages. The 2500 LB Slip On Flange is made of high-quality stainless steel and has all the quality certificates. We also expertise in manufacturing EN 1092-2 CS Class 2500 Weld Neck Flange, which is similar to the slip-on flanges but here, the bore consists of tapered thread. Our 2500# Forged Flanges are widely used to connect the pipes, valves, and other components that help build the piping system.
We produce EN 1092-2 CS Class 2500 Weld Neck Flange with two designs- the regular type and the larger type. The regular one is used with the pipes, while the other one is for the process plants. We are one of the best suppliers of #2500 and other pressure rating flanges of different types. One Of The Oldest Manufacturer Of Class 2500 ANSI B16.5 Forged Flanges In India.
