STANDARD LOOKUP TABLE OF FLANGES

  • In the factories producing chemicals, pulp, food production, animal feed, water supply and treatment, heat, hot oil, etc., there are pipeline systems in the production process, auxiliary heating or raw material supply system. In those piping systems, there are many devices mounted on the pipes to help control flow, pressure and temperature such as industrial valves, thermostats, pressure control devices, flow meters. quantity, control valves of all kinds. As with other industries, there are also connection standards in piping systems that help to interconnect pipes and equipment installed on pipes into a synchronous system. There are many connection standards such as weld joint, threaded connection, clamp connection, and flange connection, etc.

     According to current design and usage, we would like to have article introducing flanged connection standards, which is the most common type of connection in industry. Because the feature is quick to install and convenient to repair and replace. Consists of commonly used flange standards are as follows:

 

  •      JIS Flange Standard (Asian Standard)

  •      DIN flange standard (European standard)

  •      ANSI Flange Standards (American Standards)

     Due to each different connection standard, there are differences in size thickness, number of holes and center of hole. So customers need to pay attention to choose alternative products that suit their needs.

1. Flange size standard of JIS - Asian standard:

2. Flange size standard of DIN - European standard:

3. Flange size standard of ANSI - USA standard:

   Note: In this article, we only talk about the center hole size, number of holes and flange diameter of different flange standards. Because according to different standards, there are many different types and designs of flanges.

       If you have questions about industrial valves, control valves as well as the specifications of each different standard. Please feel free to contact our technical team for more direct communication about the product.
