A Flange Is a Projecting Rim,Collar,or Ring on a Shaft,Pipe,Machine Housing,etc.

A flange is a projecting rim, collar, or ring on a shaft, pipe, machine housing, etc., cast or formed to give additional strength, stiffness, or supporting area, or to provide a place for the attachment of other objects. The term "flange" is also used for a kind of tool used to form flanges. At present there are many different flange standards to be found worldwide. To allow easy functionality and inter-changeability, these are designed to have standardised dimensions. ASA/ANSI (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KIS (Japanese/Korean) are Common world standards. In most cases these are not interchangeable. Further many of the flanges in each standard are divided into "pressure classes", allowing flanges to be capable of taking different pressure ratings. Again these are not generally interchangeable (eg an ANSI 150# will not mate with an ANSI 300#). These "pressure classes" also have differing pressure and temperature ratings for different materials. The flange faces are made to standardized dimensions and are typically "flat face", "raised face", "tongue and groove", or "ring joint" styles, although other obscure styles are possible. Flange designs are available as "welding neck", "slip-on", "boss", "lap joint", "socket weld", "threaded", and also "blind". Pipe flanges that are made to standards called out by ASME/ANSI B16.5 or ASME/ANSI B16.47 are typically made from forged materials and have machined surfaces. They are typically in "Pressure Classes" such as 150#, 300#, 600#, 900# 1500#; However, ASME B16.47 still recognizes the 75# or "Class 75" flange for certain low pressure and low temperature applications. 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 ). These flanges are recognized by ASME Pipe Codes such as ASME B31.1 Power Piping, and ASME B31.3 Process Piping. Materials for flanges are usually under ASME designation: SA-105 (Specification for Carbon Steel Forgings for Piping Applications), SA-266 (Specification for Carbon Steel Forgings for Pressure Vessel Components) or SA-182 (Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service). Flanges in other countries also are manufactured according to standards for materials, pressure ratings, etc. Such standards include DIN and/or ISO standards Different flanges are used in different areas. Common flanges used in plumbing are the Surrey flange or Danzey flange, York flange, Sussex flange and Essex flange. Surrey and York flanges fit to the top of the hot water tank allowing all the water to be taken without disturbance to the tank. They are often used to ensure an even flow of water to power showers. An Essex flange requires a hole to be drilled in the side of the tank. There is also a Warix flange which is the same as a York flange but the shower output is on the top of the flange and the vent on the side. The York and Warix flange have female adapters so that they fit onto a male tank, whereas the Surrey flange connects to a female tank In plumbing, a closet flange is a pipe fitting that both mounts a toilet to the floor and connects the toilet drain to a drain pipe. The name comes from the term "water closet", the traditional name for a toilet. A typical closet flange is composed of an ABS or PVC hub with a round steel mounting flange attached to the top. Other styles are made from copper, brass, stainless steel, or pure plastic. In a typical installation, the closet flange is mounted on top of the floor with the hub fused around the drain pipe. A wax ring is used to seal the gap between the flange and the bottom of the toilet. The toilet is bolted to the flange, not to the floor. I think the robot flange is very Avant-garde. Motor Technology has expanded its range of servo worm gearboxes with the addition of a new design that features a space saving robot flange output. Derived from the robotics industry, where it is commonly used, the term ‘robot flange’ relates to an output face to which a driven component can be directly attached. This configuration is a space saving device which, when combined with right-angled design results in a very compact unit. Source: Globalfastenermarket. Com
