Silicon HDPE information pipe

This product relies on the structural protection of the HDPE outer tube and the ultra-low friction lubrication of the silicon core layer to achieve long-distance, high-speed, and damage-free air-blowing cable laying for optical cables. Unlike the conventional cable laying of ordinary HDPE communication pipes and the bundled centralized laying of quincunx HDPE pipes, it is mainly used for cross-regional, long-distance, and large-span communication optical cable trunk laying. 

It is a core supporting pipe material for communication operators and municipal transportation long-distance communication networks. The standard nominal outer diameter is dn32, dn40, dn50, and dn63mm, and it is mostly supplied in long-length coils to meet the long-distance laying needs of air-blowing construction.

Product Features

1. HDPE outer tube with a permanent silicon core lubrication layer on the inner wall, ultra-low friction, specially designed for air-blowing fiber optic cable installation, requiring no additional lubricant;

2. Ultra-long coil supply (500/1000m mainstream), fewer joints, equipped with dedicated sealing joints, zero leakage, ensuring air-blowing pressure;

3. High flexibility, cold-bending, ring stiffness SN4/SN8, buried and resistant to external pressure, corrosion and weather resistant (-40℃~80℃), anti-aging;

4. Primarily small and medium diameter (DN32/40/50/63 mainstream), lightweight HDPE structure, smooth inner wall, air-blowing does not damage the fiber optic cable;

5. Solid wall structure, uniform diameter, supports single-tube air-blowing of 1~4 micro-tube fiber optic cables, intensive transmission.

Key Advantages

1. High air-blowing laying efficiency: single-section air-blowing can reach 1000-2000m, far superior to traditional traction cable laying, significantly shortening the construction period;

2. Permanent lubrication of the silicon core layer, eliminating the need for later maintenance. Cable expansion can be repeatedly air-blown, with no lubrication costs throughout its entire lifecycle;

3. Extra-long coils reduce joints, ensuring high sealing reliability, preventing mud and water seepage, and guaranteeing stable air-blowing pressure;

4. HDPE material is corrosion-resistant and impact-resistant, requiring no anti-corrosion treatment when buried underground, with a service life exceeding 50 years, suitable for various soil environments;

5. High flexibility adapts to complex trench layouts, requiring no bends, allowing for manual laying, and eliminating the need for large equipment during construction.

Product Applications

1. Telecommunications Operators: Intercity/metropolitan area cross-regional optical cable trunk lines, metropolitan area communication backbone networks, long-distance optical cable transmission for broadcasting/telecommunications;

2. Transportation Engineering: Laying of communication optical cables along highways/railways/urban expressways, adapting to complex trench routes along the routes;

3. Municipal Engineering: Long-distance optical cable crossings across rivers/tunnels in cities, long-distance communication trunk lines for underground integrated pipe corridors and low-voltage compartments;

4. Large Industrial Parks: Laying of long-distance communication optical cable backbones throughout national-level economic development zones, port industrial parks, airport new cities, etc.
