During steel manufacturing, oxygen is forcibly injected into it to ledel. The oxygen combines with excess carbon and is released as a gas. Excess oxygen is, however, unavoidably left in the molten steel. This results in the formation of oxide…
Slip on flange dimensions are covered in ASME B16.5 – which covers Pipe Flanges and Flanged Fittings for size NPS ½” to 24” for above NPS 26” to 60” it should be as per ASME B16.47.
RTJ flanges dimensions are covered in ASME B16.5 – which covers Pipe Flanges and Flanged Fittings for size NPS ½” to 24” for above NPS 26” to 60” it should be as per ASME B16.47. During dimensional inspection of flange, you should check…
In this article, I have tried to cover some of the special flanges such as Orifice flange, long weld neck flange, reducing and expanding flanges and flange olet that used in piping and equipment.Special flanges are not as common as regular flanges.
The flange is second most used joining method after welding. Flanges are used when joints need dismantling.
