SAE Flanges

product description：

sae flange structure type introduction:

SAE flange joint (flange, joint) consists of a pair of flanges, a washer and many bolts and nuts. The gasket is placed between the two flange sealing faces. After tightening the nut, the specific pressure on the surface of the washer reaches a certain value, then it deforms and fills up the unevenness on the sealing surface, making the joint tighten. Flange joints are removable joints. According to the connection position, it can be divided into container flange and pipe flange. SAE flanges are divided into structural types, including integral flanges, ring flanges and threaded flanges. Common integral sae flanges have flat welding flanges and butt welding flanges. The flat welding flange has poor rigidity and is suitable for applications with a pressure p≤4MPa. Butt-welded flanges, also known as high neck flanges, have high stiffness and are suitable for high temperature and high pressure applications.

 High-pressure SAE flanges have low productivity and large machining allowances, but the tools are simple and versatile, so they are widely used to forge single-piece and small-batch simple forgings. Free forging equipment including air hammer, steam hammer and hydraulic press, suitable for the production of small, medium and large forgings. Die forging is characterized by high productivity, simple operation, and easy mechanization and automation. Die forgings have high dimensional accuracy, small machining allowances, and more reasonable fiber structure distribution in forgings, which can further increase the service life of parts.
