In the automobile industry, it is a rule of thumb to choose the material of automobile flange. In most cases, the material of automobile flange and tube assembly remains unchanged. There are many designs of automobile flange available in the market, such as welding neck, sliding sleeve, flat, blind and threaded. These designs are manufactured in such a way that they can meet the requirements of specific target applications. In addition, automobile flange manufacturers are also keen to customize different sizes of flange according to the needs of end users. These automobile flanges need to pass some standards before they are put on the market, such as ASME standard (USA), European dimension en / DIN, etc.
