What is the process by which seamless pipe is made?

Welding two pieces of metal
Rolling a single piece of metal
Bending a round tube
Forging a solid pipe

The correct answer is: Rolling a single piece of metal

The process by which seamless pipe is made involves rolling a single piece of metal, which is typically done using a method known as rotary piercing followed by elongation. In this process, a solid round billet of metal is heated and then pierced to create a hollow tube. This tube is then further rolled and elongated to reach the desired dimensions without any seams or joints. The absence of seams is critical because it enhances the structural integrity of the pipe, making it suitable for high-pressure applications and reducing the risk of leaks. Understanding this process is essential for those studying millwright practices, as it relates to how pipes are utilized in various industrial applications, and the quality and type of pipe used can significantly impact performance in mechanical systems.
