Abstract

PURPOSE: To get a flexible composite pipe which is insulating, easy to handle and long in life at a low cost, by inserting a polybutene resin pipe in a corrugated polyolefin pipe.
CONSTITUTION: A polybutene pipe 1 is inserted in a corrugated polyolefin pipe 2 to form a flexible composite pipe. The kind of corrugation, corrugation pitch and thickness of the corrugated pipe 2 are determined in accordance with the caliber and the use, and the kind of its material is selected among various kinds of polyolefin resin to keep the pipe heat-resistant, weather-proof, physically strong and flexible and polypropylene is most appropriate in terms of thermal properties with regard to the polybutene pipe 1. The pipe 1 can protect the corrugated pipe 2, prevent destruction when applied at curves and keep the composite pipe highly insulated due to the corrugated spaces 3.
