  1. Flanges: Types of Pipe Flanges In this Presentation you will learn about the different type of flanges that are used in piping based on pipe connection. There are many ways to classify Flanges. In this video you will learn about the classification of Flanges based on end connection. www.citizenmetals.com

  2. What are Flanges ? Flanges are the second most used joining method for connection after welding in piping. Flanges connect the pipe with various equipments and valves. It provides flexibility for maintenance. Different types of end are used to connect flange with pipe depending upon the design requirements. www.citizenmetals.com

  3. Types of Flanges. Based on the type of connection, flanges are classified as Threaded Flanges Socket Weld Flanges Slip On Flanges Lap Joint Flanges Weld Neck Flanges Blind Flanges www.citizenmetals.com

  4. Threaded Flanges Threaded Flanges are also known as Screwed Flange and it has a thread inside the flange bore which fits on the pipe matching male thread on the pipe. This type of joint connection is speedy and simple but not suitable for high pressure and temperature applications. Threaded Flanges are mostly used in utility services such as air and water. www.citizenmetals.com

  5. Socket Weld Flanges Socket Weld Flanges has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe. Generally, it is used in small bore pipe and only suitable for low pressure and temperature application. www.citizenmetals.com

  6. Slip on Flanges Slip on Flanges has small holes with matching outside diameter of pipe from which pipe can pass. The Flange is placed on the pipe and fillet welding is done from both inside and outside. Slip on Flanges is suitable for low pressure and temperature application. This type of flange is available in large size also to connect large size bore pipe with storage tank nozzle. www.citizenmetals.com

  7. Lap Joint Flanges Lap Joint Flanges is having two components a stub end and a loose backing flange. Stub end is butt welded to the pipe and backing flange freely move over the pipe. The backing flange can be made of a different material than a stub end material and normally of the carbon steel to save the cost. Lap Joint Flanges is used where frequent dismantling is required and space is constrained. www.citizenmetals.com

  8. Weld Neck Flanges Weld Neck Flanges are mostly widely used flanges in process piping. It gives the highest level of joint integrity due to butt welded with a pipe. These types of flanges are used in high pressure and temperature applications. Weld Neck Flanges are bulky and costly compared to other flanges. www.citizenmetals.com

  9. Blind Flange The Blind Flange is a blank disc with bolt holes. These types of flanges are used with other type of flange to isolate the piping system or to terminate the piping as an end. Blind Flanges are also used as manhole cover in the vessel. www.citizenmetals.com
