梅花 pipes feature a porous monolithic structure for even stress distribution. The product has a low friction coefficient on the inner wall, allowing for easy and quick cable installation, and is simple to construct. It has multiple holes for reserved pipe openings, enhancing the utilization of communication holes. The product is suitable for a wide temperature range (+80-40°C), usable in both tropical and cold regions. The joints use a sleeve structure, enabling tool-free connections between pipes for ease of installation and maintenance. The梅花 pipes have a long service life and can be used for years when buried. The pipes have a uniform color and are white, but can also be customized to other colors upon customer request. The pipes are smooth and flat with a uniform color, free from deformation, warping, or other defects. Both the inner and outer pipe walls must be free from cracks, damage, or perforations.
