DEVICE AND METHOD FOR COMPOUNDING REINFORCED COMPOSITE PIPE OF COMPLETELY BONDED TYPE

WIPO Patent Application WO/2022/267074

A1

The present invention belongs to the technical field of composite pipe compounding, and discloses a device and method for compounding a reinforced composite pipe of a completely bonded type. The device comprises a plasma generation device and air heating devices, wherein the air heating devices are arranged on two side edges of the plasma generation device. After the device is mounted, hot air injection nozzles of the air heating devices on the two sides face a pipe needing to be compounded and a reinforced strip to be compounded to the pipe, and a plasma injection nozzle of the plasma generation device faces a position between the pipe needing to be compounded and the reinforced strip, so that a plasma treatment can be carried out after heating. In the present invention, by means of a plasma treatment, the compounding temperature is lowered, the compounding performance and compounding efficiency of the reinforced pipe of the completely bonded type are improved, and time required for machining operations is saved.
