The flange table chart is a tool used by engineers and technicians to identify the dimensions and tolerances of a flange.
The chart is divided into sections based on the type of flange, such as weld neck, slip-on, and threaded. Each section contains a table with the dimensions and tolerances for that type of flange. The flange table chart is an essential tool for anyone who works with or designs flanges.
Flanges are used to connect valves ( including safety relief valves) to pipelines, facilitating their removal and maintenance.
There are many standards and in these standards you can find different types of flange. For example:
- flat face flanges, made of materials such as cast iron and ductile iron
- raised face flanges, usually made of cast steel and stainless steel
Below there is a table that will allow you to convert flange dimensions according to the different standards:
- ANSI
- AS2129
- BS10
- BS4504
