Title:
METHOD FOR MANUFACTURING HOT WATER-PLUMBING ALUMINUM PIPE, AND HOT WATER-PLUMBING ALUMINUM PIPE MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2019/027148
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a hot water-plumbing aluminum pipe and the hot water-plumbing aluminum pipe manufactured by the method, and more specifically, to a method for manufacturing a hot water-plumbing aluminum pipe and the hot water-plumbing aluminum pipe manufactured by the method, wherein the service life of the hot water-plumbing aluminum pipe is extended by preventing contamination of the aluminum pipe by preventing hard material contained in water from adhering to the surface of the pipe and corrosion resistance, super water repellency, and chemical resistance are achieved by forming a strong coated material on the inner and outer surfaces of the aluminum pipe. Furthermore, the hot water-plumbing aluminum pipe is excellent with respect to shrinkage due to heat and workability such that a coating film does not peel off during a bending process, and has excellent thermal conductivity and thus improved heating efficiency.
