Followings are the definition, information and application of various types of flanges:
The non-standard flange is also called custom flange, it means the flange is not as per the international standard of flanges. Commonly it is designed for special application.
A flange has many dimensions data to design,in the flange standards, those flanges dimensions are indicated clearly . When we design and produce the custom flanges, we do not have any standard for reference, then we have to confirm all the dimensions. When you order the custom flange, please show all the details or requirements to our factory .
