Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time. Also known as Schedule 40, this pipe is designed for low-pressure applications. It is welded, so there is a weld bead on the inside. Use in noncorrosive environments.
