What is Phosphorus Bronze Flanges?
The Phosphor Bronze material, also known as tin bronze, is a copper alloy containing 0.5-11% tin and 0.01-0.35% phosphorus. The Phosphor Bronze Flanges have some excellent mechanical properties due to its chemical composition, like high fatigue resistance, excellent formability and high resistance to corrosion. The high tin content in the alloy enhances its corrosion resistance properties and also increases its strength. The phosphorus contributes to increase the stiffness and wear resistance properties of the alloy.
The Phosphor Bronze Flanges are available in different sizes and material standards. Their dimensions, shapes and sizes can be customized according to the specific requirements. They are used in different industries, like chemical, pharmaceutical, etc., for heat exchangers, thrust washers, valves, etc.

Phosphor Bronze Blind Flange Vs Phosphorous Bronze Weld Neck Flange
The Phosphor Bronze Blind Flange is manufactured without a bore and is used for sealing the ends of the pipes or nozzles of pressure vessels. They are used for terminating the piping connections and are placed with other flanges. They are mostly used in inactive sections of the piping system, or when the pipes require internal maintenance or repairs.
The Phosphorous Bronze Weld Neck Flange comes with a long tapered hub, which makes the flanges useful in various high pressure applications at different temperature settings. The bore of these flanges match the inner diameter of the pipe, to ensure a smooth flow. The weld neck flanges are designed for excellent stress distribution and they are buttweld to the pipes for connection.

Phosphorus Bronze Slip on Flange Vs Phosphorus Bronze Threaded Flange
The Phosphorus Bronze Slip on Flange comes with a bore in the center, and the diameter of that hole is equal to the outer diameter of the pipe. The flange is slipped into the pipe through the bore and then it is double welded, both inside and outside of the flange. It helps to reduce the chances of leakage in the piping system. However, they are mainly used for applications with lower pressure and where there is a lesser leakage risk.

The best thing about Phosphorus Bronze Threaded Flange is that they can be attached to the piping system without welding. They are used for pipes with thicker walls, and for those applications where welding bears risk of explosion. Also, the threaded flanges are ideal for those cases where space is a constraint.
