CONNECTION STRUCTURE OF DOUBLE-WALL PIPE WITH RIB

摘要

PURPOSE: A connection structure of a double pipe is provided to connect a rib of a pipe to another pipe using a separate pipe after cutting the rib in order to prevent performance degradation of an air handling unit. CONSTITUTION: A connection structure of double pipes comprises a double pipe(100), a connection pipe(200), an inner connecting pipe, and an outer connecting pipe. The double pipe comprises a connection part and an expanding part(150). The connection part(140) makes an outer pipe(110) expose to the outside. The expanding part is formed by expanding an inner pipe(120) at the end part of the connection part. The connection pipe connects between the inner pipe and the outer pipe through an inserting hole(210). The inner connecting pipe is inserted into the expanding part of the double pipe and connected to the inner pipe. The outer connecting pipe is inserted into the inserting hole of the double pipe and connected to a space between the inner pipe and the outer pipe.
