A dual wall drill pipe(also known as Reverse-circulation drilling pipe) is a type of drilling pipe that has two walls or layers. The outer wall is used to contain the drilling fluid, while the inner wall is used to transport the drilling mud or other fluids to the surface. Dual wall drill pipes are commonly used in oil and gas drilling operations, as they provide a more efficient and effective way to drill deep wells. They are also used in water well drilling and other types of drilling operations where a dual-layered pipe is needed.
