Made from flame-retardant ABS resin with added environmentally friendly flame retardants and manufactured through extrusion molding, this flame-retardant low-voltage information cable protection conduit is a fire-safety upgraded version of ordinary ABS communication conduits. While retaining the core advantages of ordinary ABS communication conduits (rigid/flexible) such as insulation, impact resistance, dimensional stability, and corrosion resistance, it achieves key performance characteristics such as self-extinguishing upon removal from flame, low smoke and low toxicity, and flame resistance through flame-retardant modification. It is specifically designed to meet the low-voltage wiring needs of enclosed/semi-enclosed spaces, densely populated areas, and key fire protection zones in buildings. It comes in two main types: flame-retardant rigid ABS communication conduits and flame-retardant flexible ABS communication conduits, complementing ordinary ABS communication conduits to form a regular + flame-retardant combination. It is a core supporting pipe material for low-voltage engineering projects requiring fire safety.
The core features of the flame-retardant ABS communication conduit are "upgraded flame retardancy + full retention of the inherent advantages of ABS base material + dual rigid/flexible structure adaptation." All features comply with fire safety regulations and low-voltage protection requirements, differentiating it from ordinary ABS communication conduits (non-flame-retardant) and flame-retardant PVC communication conduits (poor impact resistance, brittle at low temperatures). It combines high flame retardancy, high protection, and high adaptability.
Using environmentally friendly halogen-free/low-halogen flame retardants, the flame retardant rating reaches the national standard B1 level (GB 8624) / Flame Retardant B level. Upon contact with open flame, only localized melting occurs, and it self-extinguishes within 3-5 seconds after the flame is removed, eliminating the risk of fire spread. During combustion, it produces no toxic or harmful dense smoke or irritating toxic gases, only a small amount of low-smoke molten droplets, complying with fire safety regulations for buildings and densely populated areas, preventing low-voltage wiring from becoming a source or contributor to fires.
Flame retardant modification does not alter the inherent properties of the ABS material. It still possesses excellent electrical insulation (isolating stray currents, preventing electromagnetic interference, ensuring stable low-voltage signals), high impact resistance (not easily damaged by bumps/compression, superior to flame-retardant PVC), dimensional stability (no deformation/brittleness at -30℃~75℃ temperature changes, low thermal expansion coefficient), and corrosion resistance (does not react with acids, alkalis, salts, cement mortar, or humid air, requiring no anti-corrosion maintenance), fully meeting the basic protection needs of low-voltage cables.
Available in flame-retardant rigid and flexible versions, the structure is consistent with ordinary ABS communication conduits: the rigid version has high rigidity and resistance to external pressure, suitable for flame-retardant installation in straight pipe sections and buried main pipes; the flexible version can be freely cold-bent with a small bending radius, suitable for flame-retardant installation in confined spaces and complex layouts. Both versions combine flame retardant performance and structural characteristics, covering all low-voltage wiring installation methods.
The flame-retardant rigid type resists external pressure and impact, preventing deformation and collapse when buried or surface-mounted; the flame-retardant flexible type retains its toughening and modification characteristics, allowing for repeated bending without plastic deformation, and remains non-brittle even in low-temperature environments in northern regions. It will not crack during installation, dragging, or corner bending, far superior to the impact resistance shortcomings of flame-retardant PVC corrugated pipes.
The inner wall remains a precisely smooth surface, without burrs or unevenness, preventing damage to the cable insulation/outer sheath during wiring and reducing wiring resistance; it is compatible with various connection methods such as socket bonding, rubber ring sealing, and snap-on connectors. After connection, it is waterproof, sand-proof, and dustproof, achieving full enclosed protection and preventing cables from being soaked or aged in humid/confined environments. The sealing structure does not affect the flame-retardant performance.
The density is far lower than that of flame-retardant metal pipes. The small and medium-diameter flame-retardant rigid type can be manually handled, and the flame-retardant flexible type is supplied in coils (50/100m/roll), eliminating the need for frequent splicing; the pipes are easy to cut (ordinary pipe cutters/scissors are sufficient), allowing for rapid installation in confined fire protection spaces such as weak current shafts, ceiling interlayers, and concealed wall conduits, meeting the needs for rapid construction/renovation in high-risk fire areas.
Mainly focusing on small and medium-diameter refined laying, the flame-retardant rigid type has a nominal outer diameter of dn20~dn110mm, and the flame-retardant flexible type has a nominal outer diameter of dn16~dn50mm, both of which are mainstream small and medium diameters for low-voltage engineering. Wall thickness is available in light, medium, and heavy types, allowing for flexible selection based on fire protection area level, installation method, and number of cables. Single coil/single length is adapted to on-site construction, reducing the number of joints and minimizing weak points in fire protection at the joints.
Using environmentally friendly flame retardants (halogen-free/low-halogen), no toxic or harmful substances are released during production and use, preventing pollution of indoor environments, soil, and water bodies. After the pipes are discarded, they can be melted down and recycled, as the flame retardant components do not affect recycling. This meets the dual requirements of green building and fire safety, differentiating it from the pollution problems associated with traditional halogen-containing flame-retardant pipes.
The flame retardant integrates well with the ABS base material, and long-term use (buried/exposed/enclosed environments) will not result in flame retardant leaching or failure, ensuring long-term and stable flame retardant performance. At the same time, it retains the UV resistance and aging resistance characteristics of ABS, preventing powdering and cracking of the pipe body even when exposed outdoors (in areas requiring fire safety), with a designed service life of over 30 years.

Flame-retardant ABS communication conduit is a specialized upgraded piping material for low-voltage electrical engineering projects with fire safety requirements. Its core value lies in solving the dual pain points of ordinary ABS communication conduits ("lack of flame retardancy, prohibited in fire-prone areas") and traditional flame-retardant low-voltage conduits (PVC/PE) ("poor impact resistance, unstable dimensions, and poor low-smoke performance"). It achieves a triple combination of "flame-retardant fire safety performance + high-performance ABS base material + rigid/flexible dual structure".
By creating a **"flame-retardant version + regular version"** scenario pairing with ordinary ABS communication conduits, the former is responsible for flame-retardant low-voltage wiring in enclosed spaces, densely populated areas, and high-risk fire areas, while the latter is used for conventional low-voltage scenarios without fire safety requirements. Together, they achieve comprehensive coverage of all scenarios and fire safety levels in low-voltage electrical engineering projects. Simultaneously, its environmentally friendly, low-smoke, and easy-to-install characteristics ensure that low-voltage wiring meets fire safety regulations while also considering engineering efficiency and cable protection. It is currently a cost-effective and preferred piping material for fire-rated low-voltage wiring in construction, municipal, transportation, and other fields.
