Title:
A spiral volume pipe and a concrete supply system
Document Type and Number:
Japanese Patent JP6120269
Kind Code:
B2
Abstract:
The present invention prevents tube rupture due to erosion of a kerf. By embedding a helical hard wire (4) near the inner surface (3a) of a tube (3), which is molded by the winding of a band-shaped body (1), so that the helical hard wire is disposed further inside the tube (3) than a reinforcing filament (2), if a kerf (R) is generated by a conveyed object (P) contacting the inner surface (3a) of the tube (3) when the conveyed object (P) is moved at high speed using a fluid such as compressed air, erosion due to the kerf (R) is stopped by the helical hard wire (4).
