COMPOSITE PIPE CAPABLE OF REDUCING OCCURRENCE OF TURBULENCE INSIDE A FLOW PATH AND AN ASSEMBLING METHOD THEREOF

摘要

PURPOSE: A composite pipe and an assembling method thereof are provided to stably seal a gap between a metal pipe and a synthetic resin pipe without a separate sealing member by digging into inner circumference of the synthetic resin pipe with a compressing unit of the metal pipe.;CONSTITUTION: A composite pipe(100) comprises a metal pipe(110), a synthetic resin pipe(120), and a coupling member(130). The metal pipe includes a reduction unit in which external diameter is reduced and a compressing unit(113) protruded to outer circumference of the reduction unit. The synthetic resin pipe includes a small diameter unit(121), a large diameter unit(122), and a connection unit(123). The diameter of the large diameter unit is greater than the diameter of the small diameter unit for inserting the reduction unit of the metal pipe and the compressing unit. The coupling member is connected to the outer surface of the diameter unit of the synthetic resin pipe and compresses the compressing unit to inner circumference of the large diameter unit.;COPYRIGHT KIPO 2013
