How many general classes of malleable iron fittings are available?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Malleable iron fittings are primarily classified based on their design, strength, and the different types of shapes they take. There are two general classes of malleable iron fittings: the first class is typically designated for standard weight applications, while the second class is for heavier weight applications. This classification allows pipe fitters to choose the appropriate fittings based on the specific requirements of a project, such as the pressure ratings and conditions under which the piping system will operate. Using the correct class of fitting is crucial for maintaining safety and ensuring that the piping system functions effectively over its intended lifespan. Understanding these two classes also helps in selecting the right materials for applications like gas, water, or other types of fluid transport, thereby preventing issues like leaks or failures in the system.
