Made from ABS as the core raw material and manufactured through extrusion molding, this rigid, specialized conduit for low-voltage information cables is the mainstream protective piping material for communication, network, and broadcasting low-voltage information lines in municipal, construction, and industrial park applications. Leveraging the high rigidity, high impact resistance, excellent insulation, and dimensional stability of ABS material, it is specifically designed for the laying of low-voltage information cables such as fiber optic cables, network cables, cable TV lines, and building intercom lines. It is suitable for various installation methods, including buried, surface-mounted, through-beam and through-wall installations, and within cable trays. Unlike MPP power pipes (for high-voltage power) and PE pipes (for large-diameter buried communication lines), it focuses on small and medium diameters, is suitable for both indoor and outdoor use, and provides refined protection for low-voltage information networks, making it a core supporting piping material for low-voltage information networks.
The features of rigid ABS communication pipes are based on the inherent advantages of ABS material and the specific protection requirements for low-voltage information pipelines. They combine a rigid structure with excellent overall performance, meeting the needs of laying, protecting, and maintaining low-voltage cables.
ABS material is a high-molecular material combining hardness and toughness. The pipes have strong rigidity, are not easily deformed or collapsed, and can withstand the static load of soil after burial and light vehicle dynamic loads. At the same time, their impact resistance is far superior to PVC communication pipes. They are not easily damaged by bumps and drops during construction, and can withstand minor external impacts when laid above ground, ensuring both structural stability and construction durability.
Rigid ABS is an insulating polymer material with stable dielectric properties and no conductivity. It can effectively isolate stray currents from the soil and external electromagnetic interference, preventing signal attenuation and crosstalk in low-voltage cables (fiber optic cables, network cables), and ensuring the transmission stability of communication and network signals. This is a core protection feature for low-voltage information pipelines.
The inner wall of the pipe is precisely extruded and molded, smooth without burrs or unevenness, and has minimal friction resistance. Fiber optic cables and network cables can be easily threaded through the pipe manually or mechanically without scratching the insulation layer/outer sheath of the cables; it also reduces the tensile force loss during cable threading, reducing the difficulty of future pipeline maintenance.
ABS material has a low coefficient of thermal expansion. The pipes maintain good dimensional stability over a wide temperature range of **-40℃ to 80℃**. They do not become brittle and crack in the low temperatures of northern winters, nor do they soften and deform in the high temperatures of southern summers. They are less affected by soil temperature changes when buried, and do not require additional heat/freeze protection when laid above ground, demonstrating strong environmental adaptability.
Made of pure ABS material, it does not react with acids, alkalis, salts, sulfides, or mildly corrosive media in the soil. It is rust-free, swelling-free, and aging-resistant, and can be used stably in ordinary soil, mildly saline-alkali land, and within building walls/concrete. No anti-corrosion treatment is required, and the designed service life can reach more than 30 years.
The pipe material has a low density and is much lighter than steel pipes and concrete pipes, and even lighter than rigid PVC pipes of the same specifications. Conventional small and medium diameters (dn20~dn110) can be directly handled, cut, and laid manually without large equipment; the pipe material is easy to process and can be quickly cut on-site according to needs, adapting to the flexible laying requirements of the construction site.
It supports multiple connection methods such as socket connection, adhesive connection, and rubber ring sealing connection. The connection process is simple, and after bonding/sealing, it can achieve good waterproof and sand-proof effects, effectively preventing groundwater, sand, and dust from entering the pipe, avoiding water immersion and sand abrasion of weak current cables, and providing a fully enclosed protective environment for the cables; the joints are not prone to leakage during buried laying, adapting to humid underground environments.
The conventional model has basic flame retardancy, and the modified model can achieve flame retardancy/fire resistance class B. It is not easy to burn continuously when exposed to open flames, and no toxic or harmful gases are released during combustion, meeting the fire safety requirements of enclosed spaces such as building interiors, weak current shafts, and cable trays, and complying with the laying specifications of building weak current pipelines.
The product mainly features small and medium diameters, with standard nominal outer diameters of dn20, dn25, dn32, dn40, dn50, dn63, dn75, and dn110mm. Wall thickness is available in light, medium, and heavy types, allowing for flexible selection based on the number of cables, laying method (underground/surface), and operating environment. It is available in both coiled and straight pipe forms; coiled pipes are suitable for small-diameter, short-distance flexible laying, while straight pipes are suitable for large-diameter, long-distance underground/surface laying.
The production raw material is environmentally friendly ABS resin, which does not release toxic or harmful substances. The production and use processes will not cause secondary pollution to soil, water bodies, or indoor environments. After the pipes are scrapped, they can be recycled and remelted for reprocessing, resulting in high resource utilization and meeting the building material requirements of municipal low-voltage and green building projects.
