Made from flexible ABS material through optimized formulation and extrusion molding, this flexible low-voltage information cable protection conduit is a flexible complement to rigid ABS communication conduits. While retaining the core advantages of ABS material, such as insulation, impact resistance, corrosion resistance, and dimensional stability, it achieves free bending and resistance to repeated bending through formula modification or corrugated pipe structure design. It is primarily designed for low-voltage applications involving small and medium diameters, complex routing, confined spaces, and precise installation. It is suitable for non-linear routes and narrow embedded spaces that rigid ABS pipes cannot accommodate, forming a "rigid-flexible combination" with rigid ABS communication pipes to cover all low-voltage information cable installation needs. It is a core supporting pipe material for precise and flexible installation in low-voltage engineering projects.
The core features of flexible ABS communication pipes revolve around "inherent advantages of ABS base material + flexible structure upgrade." Unlike the high rigidity of hard ABS pipes for straight-line laying and the low rigidity and easy deformation of flexible PE communication pipes, it achieves a balance of "flexibility and rigidity, bendable but not easily collapsible, and resistant to bending and impact." All features are tailored to the laying requirements of low-voltage electrical engineering in confined spaces and complex routes.
Using a toughened modified ABS formula, or designed with a corrugated outer wall and a smooth inner wall, it allows for free cold bending with a small bending radius (conventional specifications have a bending radius ≤ 10 times the outer diameter of the pipe). It can adapt to 90°/any angle turns without special elbows, perfectly fitting complex routes and meeting the laying needs in confined spaces and non-linear sections. There is no plastic deformation or pipe collapse after bending.
Still a pure insulating polymer material, its dielectric strength and volume resistivity meet national standards for low-voltage pipes. It effectively isolates stray currents from the soil and external electromagnetic interference, preventing signal attenuation and crosstalk in low-voltage cables such as fiber optic cables, network cables, and monitoring cables, ensuring the stability of communication/data transmission. The inner wall is smooth and burr-free, preventing damage to the outer sheath/insulation layer of the cables during threading.
The impact resistance of modified ABS is far superior to flexible PE communication pipes. It is not easily damaged by bumps, compression, or dragging during construction; it can withstand repeated bending (non-violent bending), maintaining structural integrity after multiple adjustments in the entry section and corner sections. The pipe body does not crack or delaminate. Compared to the brittleness of PVC corrugated pipes at low temperatures, it maintains good bending resistance even in low-temperature environments in northern regions.
Continuing the advantage of ABS material's low thermal expansion coefficient, the operating temperature range is -30℃~75℃. It does not become brittle in low temperatures during northern winters or soften and deform in high temperatures during southern summers. Buried pipes are minimally affected by soil temperature changes. When installed on walls or ceilings (exposed or concealed), the pipes will not shrink or bulge due to temperature changes, offering significantly better dimensional stability than flexible PE pipes.
The pure modified ABS material does not react with acids, alkalis, salts, or mildly corrosive media in the soil, nor with humid air or cement mortar in walls. It is rust-free, swelling-free, and aging-resistant. No anti-corrosion treatment is required for buried, concealed indoor, or exposed ceiling installations. The designed service life is over 30 years.
The density is significantly lower than metal pipes, and it is supplied in coils (conventional small diameters are shipped in rolls). Single coil lengths can reach 50/100m, eliminating the need for frequent splicing. Handling and installation do not require large equipment. It can be manually installed in confined spaces such as wall conduits, ceiling cavities, and corners of weak current shafts. Cutting is easy (ordinary scissors/pipe cutters can be used), greatly improving the construction efficiency of precise installations.
It features various connection methods, including socket bonding, rubber ring flexible socket connection, and special connector buckles. The process is simple and easy to operate. After connection, it provides excellent waterproofing, sand and dust protection, effectively preventing groundwater, wall seepage, and sand from entering the pipe, avoiding cable immersion and sand abrasion. It provides fully enclosed protection for weak current cables, meeting the installation requirements of underground/humid/enclosed environments.
The standard model is a basic flame-retardant type, while the modified version achieves B-grade flame retardancy/fire resistance. It does not easily sustain combustion when exposed to open flames, and no toxic or harmful gases are released during combustion, fully meeting the fire safety requirements of enclosed spaces such as building interiors, suspended ceilings, weak current shafts, and underground garages, and is suitable for the standardized and refined laying of weak current systems in buildings.
All specifications are small-diameter, with standard nominal outer diameters of dn16, dn20, dn25, dn32, dn40, and dn50mm. These are the mainstream specifications for home decoration, building pre-embedding, and weak current entry into buildings. Wall thickness is available in light and medium types, allowing for flexible selection based on the number of cables (single cable / 2-3 thin cables) and laying method (concealed / surface-mounted / buried). All are supplied in coiled form, reducing the number of joints.
The production raw material is environmentally friendly modified ABS resin, without the release of toxic or harmful substances. The production and use process will not cause secondary pollution to the indoor environment, soil, or water bodies; after the pipe is scrapped, it can be melted and recycled for reprocessing, resulting in high resource utilization and meeting the environmental protection requirements of green building projects and municipal weak current engineering.
