Plum Blossom pipes, also known as plum blossom tubes and honeycomb pipes, are communication pipe materials in the shape of a plum blossom. They are primarily used as sheath pipes for communication cables in mobile, China Telecom, China Unicom, China Netcom, and broadcasting & television.

The plum blossom pipe features a porous monolithic structure, ensuring even stress distribution. The product has a low friction coefficient on the inner wall, allowing for easy cable passage and straightforward installation. It has multiple hole positions, allowing for reserved pipe holes to enhance communication hole utilization. The product has a wide temperature range suitability (+80-40°C), making it suitable for both tropical and cold regions. The joints use a sleeve structure, enabling tool-free connections between pipes for convenient construction and maintenance. The plum blossom pipe has a long service life, usable for many years in buried conditions. The pipe material has a uniform color and is white, but can also be customized to other colors according to customer requirements. The pipes are smooth and flat, with uniform coloration, and no deformation or twisting defects are allowed. Both the inner and outer pipe walls must be free of cracks, breaks, and perforations.
