Document Type and Number:
WIPO Patent Application WO/2014/007227
Kind Code:
A1
Abstract:
Provided are a structure with an embedded pipe, for which adhesion between a pipe for forming a flow path and a metal member has been improved, and a method for manufacturing the structure. The structure with the embedded pipe (1) is equipped with: a metal or alloy pipe (10) that has a flattened circumference curved at both ends in the length direction in a cross section; a metal or alloy base material (11) that has a concave section (11a) for fitting the pipe (10), said concave section having an inner wall for bringing a circumferential section (10c) in the length direction into contact therewith; and a deposition layer (12) that is formed by accelerating metal or alloy powders together with a gas and spraying the powers in a solid state to the pipe (10) and base material (11) surfaces in a state wherein the pipe (10) is fitted in the concave section (11a) in order to deposit the powders thereon. The ratio (h/R) between the protruding amount (h) of the pipe (10) from a surface of the base material (11) and the curvature (R) at the end sections (10a, 10b) is 0.25 - 0.5 inclusive.
