What is the correct "height" or "size" for a piece of oils rigs to become a candidate for "rigs to reef." Remember, oil rigs can be cut into different sizes or parts.

Answer and Explanation:

An oil rig is a type of piston ring which is situated in the ring grooves. The oil ring is commonly used on small engines to wipe excess oil from the wall of the cylinder during the piston's movement. Through the opening of rings, excess oil returned to the oil reservoir. These rings are not used on the two-stroke cycle engines. These rings are one-piece or two-piece. An oil ring seals the combustion chamber through inherent pressure and controlling the consumption of oil. The inherent pressure of the oil ring is very high on the piston. These rings use an expander, high-pressure unit and inherent pressure. The oil rings are also used to spread the oil around the liner surface.  These rings can be cut into various sizes. An oil ring has an axial.
