A method for making bi-metallic members includes the steps of anodizing aluminum coming off of a coil, providing a metallic outer ring member having an inner hollow section by using a die to punch out the member off of the coil, providing a metallic inner core member by using a die to punch out the member off of the coil so that its shape fits within the inner hollow section of the metallic outer ring member, inserting the metallic inner core member into the inner hollow section of the metallic outer ring member so as to form a bi-metallic member, stamping the bi-metallic member to thereby hold the metallic inner core member and the metallic outer ring member together.

A method of forming a drum hoop is described and shown. The method can include forming connecting portions into ends of a strip of hoop material. The strip of hoop material can then be rolled such that the connecting portions interconnect. The method can also include forming an elongated edge of the strip and/or hoop of material into a rolled bend, such as a rolled bend toward the outside of the hoop. Finally, the method can include leveling the top and/or bottom surfaces of the hoop, such as leveling the rolled bend. This leveling can be accomplished by stamping one or both of the top and bottom surfaces of the hoop, the top surface in some embodiments being the top of the rolled bend.

A fitting to be connected to a pipe includes: a first member; a second member coupled by screw coupling with the first member; and a ferrule placed in an accommodation space formed by an inner circumferential surface of the first member, an inner circumferential surface of the second member, and an outer circumferential surface of the pipe. The ferrule has a rising portion including a first end portion, a pressed portion located closer to a second end portion than the rising portion, and an intermediate portion including a portion where an inner diameter is greater than the first end portion and the second end portion, the intermediate portion connecting together the rising portion and the pressed portion. The first member has a first tapered inner circumferential surface, which is an inner circumferential surface having a tapered shape, to be in contact with the first end portion of the ferrule. The second member has a pressing portion for pressing at least a portion of the pressed portion of the ferrule. The accommodation space has a first clearance space for accommodating the ferrule therein and allowing the rising portion to rise so as to increase an angle of the rising portion with respect to the outer circumferential surface of the pipe.

In a case of a mark left type, a slit is formed on a line side (slit side) of a joint portion. The slit is formed, for example, with a scroll saw. By the formation of the slit, a length of the joint portion in a direction orthogonal to an axial direction of a single ring is set to approximately 0.7 mm. In a case of a mark removed type, a slit and a slit are formed respectively on the line side (slit side) and a side opposite thereto of the joint portion. Those slits are formed, for example, with the scroll saw. By the formation of those slits, the length of the joint portion in the direction orthogonal to the axial direction of the single ring is set to approximately 0.8 mm.
