This however depends on the outer dust rim to remain in satisfactory contact and that the inside fluid is not corrosive in case of leaking into the bolt circle void. ASME B16.5 refers to nominal pipe sizes (NPS) from ½" to 24". The classes for Ring-Joint, Tongue & Groove, and Raised-Face flanges are Class 150, Class 300, (Class 400 - unusual), Class 600, Class 900, Class 1500, and Class 2500.[2]. The gasket type and bolt type are generally specified by the standard(s); however, sometimes the standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details (see ASME Code Section VIII Division 1 – Appendix 2). The Euler-Bernoulli beam equation shows that the I-shaped section is a very efficient form for carrying both bending and shear loads in the plane of the web. A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange). The ASME pressure classes for Flat-Face flanges are Class 125 and Class 250. THREADED FLANGE Threaded flanges are joined to pipes by screwing the pipe (which has a male thread, generally NPT per ASME B1.20.1) onto the flange, without seam welds (in certain cases, though, small welds are applied to increase the strength of the connection).. Threaded flanges are available in sizes up to 4 inches and multiple pressure ratings, however, they are used, mostly, small … Ski boots use flanges at the toe or heel to connect to the binding of the ski. They also have a flange on one side to keep the wheels, and hence the train, running on the rails, when the limits of the geometry based alignment are reached, e.g. Unique pressure classes for piping can also be developed for a process plant or power generating station; these may be specific to the corporation, engineering procurement and construction (EPC) contractor, or the process plant owner.

The seal ring force is provided by the elastic stored energy in the stressed seal ring. an ASME 150 will not mate with an ASME 300). To allow easy functionality and interchangeability, these are designed to have standardised dimensions. ANSI flanges are round, use through bolts and/or nuts to attach two matched flanges together or to a valve or other mechanical device. an ASME flange will not mate against an ISO flange). to which local standards including DIN, BS, and others, have been aligned. It also provides easy access for cleaning, inspection or modification. A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. They are often used to ensure an even flow of water to showers. The relief line belongs to the high-pressure, large-diameter pipeline; as a result, it should use the welded flange instead of the screw joint flange (Figs. The ball slides within a bored cylinder, against the pressure of a spring, which pushes the ball against the detent, a hole of smaller diameter than the ball. Critical flange dimensions help to identify the standard . ANSI Class Flange Types Regardless of size or specification, flanges are fundamentally designed to close, cover, connect, or support pipe systems. Good designers and engineers have experience and knowledge and the ability to communicate their thoughts and ideas clearly with others. It is an ‘International Day’ established by the United Nations to recognize and promote the contribution made by volunteers and voluntary organizations to the wellbeing of people across the globe. Only in few cases it can be fabricated from plates. The size of pipes, fittings, flanges and valves are often given in inches as NPS - Nominal Pipe Size, or in metric units as DN - 'Diametre Nominal' A wide edge on a pillow, placemat, or other fabric object, especially a piece of fabric or ribbon extending from the outer seam. This however requires the IX ring to be retained in the theoretical location in the ring groove which is difficult to ensure and verify during installation. (Chemical Engineering: Fluids storage and transport) A flange is a flat plate used for connecting two pieces of pipe. A flange is a disc-shaped part, also called a flange or flange. There are many different flange standards to be found worldwide.

Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges': Common flanges used in plumbing are the Surrey flange or Danzey flange, York flange, Sussex flange and Essex flange. A Flange is a protruding wheel-shaped end of equipment that is fastened to another end of an object to facilitate attachment. The first seal is created by application of seal seating stress at the flange heel, but it is not straight forward to ensure the function of this seal. ‘the flanges that held the tailpipe to the aircraft’ However these classes do not correspond to maximum pressures in psi. Weld Neck Flanges. A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel.
