Plum Blossom pipes are communication piping materials in the shape of a plum blossom, also known as plum blossom pipes and honeycomb pipes. They are primarily used for the protective sheath of communication cables in mobile, China Telecom, China Unicom, China Netcom, and cable TV industries.

The plum blossom pipe features a porous monolithic structure for even load distribution. The product has a low friction coefficient on the inner wall, allowing for easy and quick cable passing, and is easy to install. It has multiple holes, allowing for reserved pipe holes to enhance communication hole utilization. The product is suitable for a wide temperature range (+80 to -40°C), making it usable in both tropical and cold regions. The joints are designed with a sleeve structure, enabling tool-free connections between pipes for convenient installation and maintenance. The plum blossom pipe has a long service life and can be used for years under burial conditions. The pipe material has a uniform color, which is white, and can also be customized to other colors upon customer request. The pipe surface is smooth and even, without any deformation or warping defects. Both the inner and outer pipe walls must not have cracks, breaks, or perforations.
