A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. The principle of a flange is to apply a mechanical force by using bolts to preload the gasket until contact stress between flanges and gasket is sufficient to maintain a seal. Connection to the pipe is by welding or threading. To allow easy functionality and inter-changeability, these are designed to have standardised dimensions which include ANSI, ASME, DIN, EN, BS, JIS. Super Duplex S32760 Flanges have major applications in Oil, Gas, Petrochemical, Ship-Building, Marine, Food, Dairy, Railways and other associated industries were piping systems are required. Super Duplex Stainless Steel Pipe Flanges are available in following forms:

Super Duplex Slip On Flange — Super Duplex Slip-On Flanges is slightly larger than the outer diameter of the pipe it is to be used with. The pipe is slipped into the Flange prior to welding both inside and outside. We supply a wide range of slip-On Flanges in different dimensions and sizes.

Properties of Super Duplex 4501

Super Duplex 4501 Cold Forming

Super Duplex 4501 can be readily formed with the most of the common cold-forming methods. When forming requires more than 10% cold deformation, a solution anneal and quench are recommended.

Super Duplex 4501 Hot Forming

Super Duplex 4501 should be hot worked between 1875°F and 2250°F. This should be followed by a solution anneal at 1925°F minimum and a rapid air or water quench.

Super Duplex 4501 Machining

Super Duplex 4501 in the annealed condition is readily machinable by all conventional methods.

Super Duplex 4501 Pipe Welding

Super Duplex 4501 is readily weldable using many of the standard electric arc welding processes but oxyacetylene welding is not recommended because carbon pickup in the weld metal may occur.

Super Duplex 4501 Heat Treatment

Super Duplex 4501 should be solution annealed and quenched after either hot or cold forming. Solution annealing should be done at a minimum of 1925°F. Annealing should be followed immediately by a rapid air or water quench. To obtain maximum corrosion resistance, heat treated products should be pickled and rinsed.
