An Overview of Concrete Pipe's Type and Class with Standards
3. "C" Wall Concrete Pipe. The wall thickness for a "C" wall is obtained by adding 1.75 inches to the "A" wall thickness. For example, let's take a 60-inch diameter pipe equivalent to 5 feet. With the "A" wall thickness being 5 inches, the "C" wall thickness would be 6.75 inches (5 inches + 1.75 inches).
