Which of the following is not a method of forming piping?

• A. Spinning
• B. Rolling
• C. Welding
• D. Bending

Answer: (A)

The correct answer identifies spinning as not being a method of forming piping. Spinning is primarily a metalworking process where a metal disc or tube is rotated at high speed and a tool is used to shape the material into an axis-symmetric part. While spinning can be employed in creating specific components, it does not form piping in the same way as rolling, welding, or bending. Rolling involves reducing the thickness or changing the shape of a material through the application of compressive forces, which is a common method used for creating piping. Welding, on the other hand, involves combining materials through high heat to form a strong joint, which is essential in constructing piping systems. Bending is the technique used to change the shape of a pipe or tube, allowing it to fit into various configurations necessary for piping systems. In summary, spinning is more suited for creating specific shapes and components, while rolling, welding, and bending are integral processes in forming and fabricating piping.
