carbon steel plate flanges

Product Details

The carbon steel plate flanges are produced by forging, casting, medium plate rolling and medium plate cutting. The production process includes forging, casting, medium plate rolling, and medium plate cutting. Among them, the forging price is the highest, the middle plate product is the second, and the foundry product is the lowest. In terms of quality, the best for forging, the second for rolling, and the third for casting. However, the forgings are generally small in diameter. Carbon steel is one of the most widely used materials on the market, and it is cheap and durable. There are three types of high-pressure carbon steel flange sealing surfaces: flat sealing surface, suitable for occasions where pressure is not high and medium is non-toxic; concave and convex sealing surface is suitable for occasions with higher pressure; groove sealing surface is suitable for flammable , explosive, toxic media.

A plate flange is a flat, circular disk that is welded onto the end of a steel pipe and allows it to be bolted to another pipe. Typically used in fuel and water pipelines, the two flange plates will be bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints
