Title:
RESIN COMPOSITE PIPE, PIPING STRUCTURE AND PIPING SYSTEM
Document Type and Number:
Japanese Patent JP2022052405
Kind Code:
A
Abstract:
To provide a resin composite pipe which suppresses a manufacturing cost, and can reduce a defective rate, a piping structure using the resin composite pipe and a piping system.SOLUTION: A resin composite pipe 1 comprises: a cylindrical resin-made inner layer 2 whose inside functions as a liquid flow passage; a reinforced resin layer 3 laminated on an external peripheral face of the resin-made inner layer 2; and an adhesion layer 4 and an oxygen barrier layer 5 which are sequentially laminated on an external peripheral face of the reinforced resin layer 3. The resin-made inner layer 2 is formed of resin, and does not contain a fibrous or powdery inorganic material, and the reinforced resin layer 3 contains a fibrous or powdery material in resin, and does not contain a thermal bonding resin layer at the outside of the reinforced resin layer 3. There are also provided a piping structure using the resin composite pipe 1, and a piping system.SELECTED DRAWING: Figure 1
