A WATER PIPE AND MANUFACTURING METHOD

摘要

PURPOSE: A pipe and a manufacturing method thereof are provided to easily prevent the internal corrosion of an outer member by forming an inner member, located inside the outer member, out of stainless steel. CONSTITUTION: A pipe(10) comprises an inner member(110) and an outer member(130). The inner member is bent on both ends to form respective joint parts and forms a C-shape when the outer sides of the joint parts are attached. The horizontal width of the outer member is shorter than that of the inner member so that the outer member is received between the joint parts while both ends of the outer member are attached to the inner sides of the joint parts of the inner member. Both ends of the outer member are placed to be located along the inner member in a C-shape and welded together.
