Inconel Flanges Traders In Mumbai
Inconel is a difficult metal to shape and machine using traditional cold forming techniques due to rapid work hardening.
After the first machining pass, work hardening tends to plastically
deform either the workpiece or the tool on subsequent passes.
Pipe flanges that are made to standards called out by ASME
B16.5 or ASME B16.47, and MSS SP-44. They are typically made from
forged materials and have machined surfaces.
ASME B16.5 refers to nominal pipe sizes (NPS) from ½" to 24". B16.47 covers NPSs from 26" to 60". Each specification further delineates flanges into pressure classes: 150, 300, 400, 600, 900, 1500 and 2500 for B16.5, and B16.47 delineates its flanges into pressure classes 75, 150, 300, 400, 600, 900. However these classes do not correspond to maximum pressures in psi. Instead, the maximum pressure depends on the material of the flange and the temperature. For example, the maximum pressure for a Class 150 flange is 285 psi, and for a Class 300 Flange it is 740 psi (both are for ASTM A105 Carbon Steel and temperatures below 100F).

For this reason, age-hardened Inconels such as 718 are machined using an aggressive but slow cut with a hard tool, minimizing the number of passes required. Alternatively, the majority of the machining can be performed with the workpiece in a solutionized form, with only the final steps being performed after age hardening.Inconel Flanges Traders In Mumbai |
