SAE flange fittings refer to flange fittings (flanges or adapters). SAE flanges can be cast (not shown), threaded or welded. SAE flanges include a pair of flanges, a washer, and several bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After tightening the nut, when the specific pressure reaches a certain value, the surface of the gasket will be deformed, filling up the uneven part of the sealing surface. SAE flange connections are tight and leak-free.
Safety engineering flanges are divided into screw connection (thread connection) safety engineering flanges and welding safety engineering flanges. Low-pressure small-diameter threaded SAE flanges, high-pressure and low-pressure large-diameter welded SAE flanges, the thickness of SAE flanges and the diameter and number of connecting bolts are different under different pressures. According to different pressure levels, SAE flanges are also made of different materials, from low-pressure asbestos gaskets, high-pressure asbestos gaskets to metal gaskets.
1. SAE flange materials are divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, ppc, etc.
2. According to the manufacturing method, SAE flanges can be divided into pushing, pressing, forging and casting.
3. According to manufacturing standards, it can be divided into national standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.
