Carbon Steel Flange

Pipe flanges are manufactured in all the different materials like stainless steel, cast iron,

aluminium, brass, bronze, plastic etc. but the most used material is forged carbon steel and have

machined surfaces. In addition, flanges, like fittings and pipes, for specific purposes sometimes

internally equipped with layers of materials of a completely different quality as the flanges

themselves, which are "lined flanges". The material of a flange, is basically set during the choice

of the pipe, in most cases, a flange is of the same material as the pipe.
