Flange Face Surface Finish

Flange Materials Specification

The choice of the material largely depends on the purpose of the flange. The usual materials of flanges include stainless steel, carbon steel, aluminum and plastic. For example, stainless steel is more durable and is necessary for heavy use. On the other hand, plastic is more feasible for use in the home because of its reasonable price and easy installation. The materials used for flanges are under the designation of the American Society of Mechanical Engineers.
Requirements are valid for normal situation, in special you have to contact us to introduce.
