Dimensions of Fiber Optic Corrugated Pipes for Intelligent Buildings

Fiber optic corrugated pipes for intelligent buildings typically range from 50mm to 250mm in outer diameter, with internal sub-ducts of 20mm to 60mm, available in coils of 200m to 500m.

Outer and Inner Dimensions

Fiber optic corrugated pipes are generally made of high-density polyethylene (HDPE) and are available in outer diameters (OD) from 50mm to 250mm depending on the project requirements. Many pipes include built-in sub-ducts for individual fiber optic lines, with internal diameters ranging from 20mm to 60mm. The sub-ducts may have one or two layers, often with a silicon inner layer that can be smooth or grooved to reduce friction during cable installation.

Wall Thickness and Material

The wall thickness of both the main corrugated pipe and the internal sub-ducts can vary according to pressure and mechanical protection requirements.

HDP

E pipes are impact and abrasion resistant, flexible, and suitable for underground installation, making them ideal for intelligent building networks. They are also weatherproof and airtight, ensuring long-term durability.

Coil Lengths and Installation

Standard coil lengths for these pipes are 200m, 255m, 300m, or 500m, but custom lengths can be requested to fit specific building layouts. The corrugated design allows easy bending and adaptation to underground obstacles, reducing the need for joints and minimizing installation time. Many pipes come with pre-installed pulling ropes to facilitate quick cable installation.

Color Coding and Identification

To simplify cable management, pipes and sub-ducts are often color-coded. Standard internal duct colors include red, white, blue, and yellow, which helps identify different fiber optic lines within the building infrastructure. External markings may also include logos or stripes according to network requirements.
