Plum Blossom pipes are communication tube materials with a plum blossom shape, also known as plum blossom pipes and honeycomb pipes. They are mainly used as sheath pipes for communication cables in mobile, iron communication, Unicom, Netcom, and broadcasting and television networks.

梅花 pipes feature a porous monolithic structure for even distribution of force. The product has a small friction coefficient on the inner wall, allowing for easy and quick cable installation, as well as simple construction. They have multiple holes, allowing for reserved pipe holes to enhance communication hole utilization. The product is suitable for a wide temperature range (+80-40), usable in both tropical and cold regions. The connectors use a sleeve structure, enabling tool-free connections between pipes for ease of installation and maintenance. The service life of the梅花 pipes exceeds many years under burial conditions. The pipes have a uniform and consistent color, white in color, and can also be customized to other colors upon customer request. The pipes are smooth and flat with a uniform color, free of deformation, warping, or other defects. Both the inner and outer pipe walls must be free of cracks, damage, or perforations.
