ABSTRACT:
Aluminum pipes 63 and 65 are provided at the ends thereof with a flange unit 3 constructed by two separate flange sections 5 and 7 produced by injection moulding a plastic material selected from polypropylene, polyoximethylen, epoxy, polyester or nylon 66. As the plastic resin material, nylon 66 is most preferable. The flange sections 5 and 7 from semicircular grooves in which the pipes 63 and 65 are accommodated, and the sections 5 and 7 are moved toward each other to be brought into a face to face contact while projected portions 27 and 29 of the first section 5 are engaged with hook portions 59 and 61 of the second section 7. Then the sections 5 and 7 are connected to each other by a screw 7, to obtain an assembled state of the flange unit 3. With this flange assembly, a contact between different metal materials does not occur, and thus any corrosion of the pipes is substantially prevented.
