Pipe threads are usually cut in to tapered form and are used to join pipes together. Tapered treads usually have tapered connection that makes it gas and liquid tight. They are mainly used for the sealing of treaded connections. The thread will fill the gap between the components as they are screwed together.
Ring grooves are used to create a 3 dimensional machined surface. It consists of two parallel surfaces called the ring lands. This parallel surface act as the sealing surfaces of the piston ring. For the proper rotation and flexibility, the clearance between the piston ring and parallel surface is very important. Sufficient clearance has to give between the depth of ring grove for the piston ring to get compressed.
