Forged Carbon Steel Stainless Steel Pipe Flanges

flange connections, which are used for two kinds of pipes, fittings, or devices, are first fixed in a flange flange, and between the two flanges, flange pads are bolted together, which completes the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. Flange connection is widely used in industrial pipeline. In the home, the pipe diameter is small, and is low pressure, not visible flange connection.

ASME/ASTM FlangesPipe 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, 9001. Standard:ASME B16.5; ASME B 16.47 Series A(MSS SP-44); ASME B 16.47 Series BAWWA C2072.

Rat ings for welding neck flanges covered by this Standard are based upon their hubs at the welding endhaving thickness at least equal to that calculated for pipe having 276 MPa (40,000 psi) specified minimum yieldstrength.1 In order to ensure adequate flange hub thick ness for flange sizes NPS 2 and larger, the bore of awelding neck flange, dimension B in the various dimen sional t ables, shall not exceed Bmax det ermined asfollows: 1. Standard:DIN2502,DIN2503,DIN2527,DIN2566.DIN2573,DIN2576; DIN2633 ; DIN2632; DIN2631;DIN25662.

Flange types:Weld NeckThis flange is circumferntially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore favoured in critical applications.Slip OnThis flange is slipped over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.BlindThis flange is used to blank off pipelines, valves and pumps, it can also be used as an inspection cover.

When building a pipeline, the length of the pipes used are not always known. By manufacturing the pipe separate from the flange plate, the welders can cut the pipe to length and weld a flange plate in place to join the pipes at any needed length. The plates can also be welded to the pipe on a slight bias, allowing two pipes to be joined that may not be precisely lined up.1.

whereas ISO 7005-1 included in its scope both the original DIN based flanges and also the originalANSI/ASME based flanges, EN 1092-1 contains only the PN based flanges. CEN/TC 74 has produced a separate series of standards, EN 1759-1, EN 1759-3 and EN 1759-4, dealing with the ANSI/ASME based flanges in their original Class designations;1.
