ASME B 16.47 is one of the American standards. It refers to one of the large-diameter steel flanges. The standard also covers the requirements about flange joint, flange bolting, flange gaskets, etc. In addition, the standard covers the design of flanges from NPS 60 to NPS 24. With the rating classifications 900, 600, 400, 300, 150, and 75, the standard ASME B 16.47 offers measurement, dimensions, marking, tolerances, and pressure temperature for the pipe flanges. ASME B16.47 standard comes in two series, Series B and Series A flanges. The differences between these flanges are: Characteristics ASME B16.47 Series A flanges are relatively thicker, heavier, and more robust than Series B flanges with the same size and pressure ratings. Hence, series A flanges can withstand extra external loading compared to the Series B flanges. Required Fasteners The fastener quality requirement for ASME B16.47 Series A flanges is lesser than the Series A. Class 150 Series A flange requires 28 bolts of 1...

There are many kinds of flanges available in the market like blind flanges , butt weld flanges, slip-on flanges, weld neck flanges, and more. Here in this blog, we’ll discuss slip-on vs. plate flanges. Meaning of plate flanges Plate flange is a circular, flat disc welded to the pipe’s end. It enables the flange to be bolted to another pipe. It is often referred to as the flange slip, plane flange, flat flange, etc. Two plate flanges can be bolted together with a gasket in between them, usually used in water and fuel pipelines. The pipe length is not always known while constructing a pipeline. The plates may also be welded with a slight bias to the shaft, allowing the two pipes not to match up and join. Plate flanges come with a notched finish on the inner mating surface that allows the plate to fit within the gasket material. In any given dimension, plate flange designs are standardized, apart from the materials used to manufacture them. It ensures that the fit is exactly like a 6-inc...

If you want to know why do forging flanges need heat treatment, you must first get an understanding of the meaning behind forgings. Forging is the use of a hand hammer, pressure equipment, or forging hammer on the mold on the heating of the metal blank force so that metal materials under the condition of non-separation plastic deformation obtain performance, size, and properties meet the requirements of parts. Need of heat treatment for the forged flange The main purpose is to refine the coarse grains, eliminate the residual stress and work hardening, reduce the hardness, improve the cutting performance, prevent the white spots while forging, and make sure about the required machinery and metal structure. Now, below are details about the heat treatment: Normalizing If you want to forge flange connections , heat treatment is the first step. Heat the forgings above the transformation temperature, form a single austenite structure, after a period of uniform temperature stability, after a ...
