What is pipe flange?
A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
What flange means?
1 : a rib or rim for strength, for guiding, or for attachment to another object a flange on a pipe a flange on a wheel. 2 : a projecting edge of cloth used for decoration on clothing a jacket with flange shoulders. flange. verb.
What are the different types of pipe flanges?
Pipe flanges can be divided into eight types based on design. These types are blind, lap joint, orifice, reducing, slip-on, socket-weld, threaded, and weld neck. Blind flanges are round plates with no center hold used to close the ends of pipes, valves, or equipment.
Which flange is used for pipe joints?
Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance.
What is flange class?
The term “flange rating” (or class) refers to the maximum pressure (in psi or bars) that a flange withstands at increasing temperatures. Flanges with a higher rating (class) are stronger than flanges with lower ratings, as they bear more pressure at increasing temperatures.
What is flange standard?
A flange standard lays down the dimensions, surface finish, facing type, marking, material and technical specifications for flanges. National flange standards in Europe have largely been superseded by the European EN 1092 series.
What does flange mean in construction?
A flange is a projecting ridge, rim, collar or ring on an object such as a column, beam, pipe and so on that provides additional strength or stiffness or additional surface area for the attachment of, or to, another object. For example, flanges may be used to strengthen beams, or to connect or terminate pipes.
How do you classify flange?
Classification of flanges based on pipe attachment
- 1.1) Slip-on Flanges: These flanges are welded on inside as well as outside to the pipe.
- 1.2) Socket-Weld Flanges: These Flanges are welded only on outside of the Pipe.
- 1.3) Screwed/Threaded Flanges:
- 1.4) Lap-joint Flanges:
- 1.5) Welding neck Flanges:
What is meant by flange rating?
How are flanges used to connect pipes?
Typically, flanges are attached to pipes via welding, brazing, or threading . Welding joins materials by melting the workpieces and adding a filler material. For strong, high pressure connections of similar materials, welding tends to be the most effective method of flange connection. Most pipe flanges are designed to be welded to pipes.
How many types of pipe flanges are there?
9 Types of Pipe Flanges – A complete Guide for Engineer Threaded Flanges. Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore… Socket-Weld Flanges. Socket-Weld Flanges has a female socket in which the pipe is fitted. Fillet welding is done from…
What are the main types of flanges?
Types of Flanges Welded neck flange: -. It is used for high temperature, high pressure operation or where there is wide fluctuation in pressure and temperature. Slip on flange: -. It is widely used because of ease of alignment in welding. Screwed flange: -. Screwed flange can be connected to threaded pipes without welding. Lap joint flange: -. Blind flanges: -.
What is the purpose of the flange?
A flange is a disc that can connect to a pipe with the purpose of providing increased strength, ending the flow or allowing for the attachment of items, such as spray nozzles, to the end of a pipe.
