HDPE Corrugated Duct

Introduction- Aramco 120mm HDPE COD

The Aramco 120mm HDPE COD is an innovative cable duct system that can serve several organized routes for fiber optic, telecom, broadband, communication, and underground cable installations. The design consists of a 120mm HDPE outer duct incorporating five separate 38mm O.D subducts.

Each one of the internal subducts has its own pull rope and also a silicon coating on its internal surface. Five color-coded separate subducts, red, green, blue, yellow, and white, make the identification of each of the paths possible during development and maintenance as well as future network improvement tasks.

Five independent cable routes merged into a single outer duct ensure that it is possible to create an organized underground cable structure and achieve a more manageable process of installation and administration of individual cables.

Product Overview

The 120mm HDPE COD x 5 Lines 38mm O.D. with Pull Rope is made up of one 120mm external HDPE duct and five individual 38mm O.D. subducts.
Each of the subducts has a rope which allows the cables to be pulled independently from the channel provided, therefore meaning that any cable may be used in the designated pathway without the need for any connectors. Additionally, each subduct has a lining of silicon in its inner wall to ensure better movement for the cables inside.

The five internal subducts are identified by different colors:

• Red = 38mm O.D.
• Green = 38mm O.D.
• Yellow = 38mm O.D.
• Blue = 38mm O.D.
• White = 38mm O.D.

The outer duct is described as 120mm HDPE.

This multi subduct system can be used in the underground telecom and communication installations where many different cable paths should be combined in a single duct route.

Key Features

1. 120mm HDPE Outer Duct

The system uses a 120mm HDPE outer duct that houses the five internal subducts.

2. Five 38mm O.D. Subducts

The product contains five separate subducts, with each subduct having a specified outside diameter of 38mm.

3. Pull Rope in Every Subduct

Each of the five subducts includes its own pull rope, providing a dedicated pulling pathway for cable installation.

4. Silicon Layer on Subduct Inner Wall

Each subduct features a silicon layer on its inner wall, providing a smoother internal surface intended to facilitate cable installation.

5. Five Color-Coded Pathways

The internal subducts are supplied in red, green, blue, yellow, and white, allowing easy identification of individual cable pathways.

6. Consolidated Duct Configuration

Five individual pathways are integrated within one outer duct, helping create a structured underground cable route.

7. Suitable for Telecom Infrastructure

The configuration can be considered for fiber optic, telecom, broadband, FTTx, and communication infrastructure applications.

8. Dedicated Cable Pathways

Each subduct can be allocated to a specific cable or network section according to the project’s design.

Technical Specifications

Technical note: Your supplied description says “Orange for Outer Duct (110mm)”, while the product name and opening specification state 120mm. The content above follows the stated product name and 120mm specification. The final outer-duct diameter and color should be verified against the manufacturer’s technical datasheet before publishing or procurement.

Wall thickness, internal diameter, dimensional tolerances, pull-rope specification, silicon-layer characteristics, mechanical properties, coil length, temperature range, and other performance parameters should also be confirmed from the applicable technical documentation.

5 × 38mm Subduct Configuration

The 5 × 38mm configuration means that the 120mm outer duct contains five individual subducts, each with a specified outside diameter of 38mm.

This arrangement provides five individually identifiable pathways within a single outer duct.

Silicon Layer for Smoother Cable Installation

Each internal subduct includes a silicon layer on its inner wall.

The purpose of the smoother internal surface is to facilitate cable installation by providing a suitable internal pathway for cable movement. Actual installation performance depends on several factors, including cable construction, cable diameter, route length, bends, installation equipment, pulling tension, and installation technique.

The silicon layer should therefore be considered as one component of the overall cable-installation system.

Pull Rope in Each Subduct

A dedicated pull rope is provided in each of the five subducts.

This allows installers to use the individual pathway for cable pulling without relying on a shared pulling system across the entire outer duct.

Individual pull ropes can help with:

• Dedicated cable installation
• Independent pathway management
• Cable pulling preparation
• Multiple installation phases
• Future cable installation
• Organized network expansion

The pull-rope capacity and installation limitations should be confirmed from the applicable product specification before cable pulling.

Color-Coded Subduct Identification

The internal subducts are supplied in five colors:

Red → Green → Blue → Yellow → White

Color coding provides a straightforward method for distinguishing the five cable pathways.

Project teams can assign each color to a specific cable, network section, route, or installation phase according to their approved design.

Color identification can help:

• Reduce pathway confusion
• Speed up cable identification
• Improve installation organization
• Support maintenance activities
• Simplify cable route documentation
• Assist future cable installation

Where a project has an established cable identification standard, the color allocation should follow the approved project documentation.

Advantages of Aramco 120mm HDPE COD

Multiple Dedicated Pathways

Five individual subducts provide separate pathways for different cables or network sections.

Organized Underground Cable Infrastructure

The multi-subduct configuration allows several cable pathways to be consolidated into a single outer duct arrangement.

Individual Pulling Capability

Each subduct has its own pull rope, supporting independent cable installation through the designated pathway.

Improved Pathway Identification

The red, green, blue, yellow, and white color scheme makes individual subducts easier to identify.

Silicon-Coated Inner Surface

The silicon layer on each subduct’s inner wall provides a smoother internal surface intended to support cable installation.

Space-Efficient Configuration

Five pathways are combined within one 120mm outer duct, creating a consolidated ducting arrangement.

Future Expansion Potential

Unused subducts can potentially provide additional cable pathways for future network expansion, subject to project capacity and design requirements.

Simplified Maintenance

Dedicated and color-coded pathways can make it easier for maintenance teams to identify the correct cable route.

Applications

The Aramco 120mm HDPE COD can be considered for various underground cable infrastructure applications.

Fiber Optic Networks

The individual subducts can provide dedicated pathways for fiber optic cables.

Telecom Networks

The five-pathway configuration can support structured telecom infrastructure where multiple cables require separate routes.

Broadband Infrastructure

The product can be incorporated into underground broadband networks requiring organized cable pathways.

FTTx Networks

The multi-subduct arrangement can support fiber access infrastructure depending on the network design and cable requirements.

Communication Networks

It can be used for communication and data cable infrastructure where dedicated underground pathways are required.

Large Infrastructure Developments

The configuration can be considered for large developments where multiple communication pathways need to be installed within coordinated underground routes.

Why Use Five Subducts in One Outer Duct?

A five-subduct configuration allows several dedicated cable pathways to be installed as part of one consolidated duct route.

This can be useful when a project requires:

• Multiple independent cable pathways
• Clear pathway identification
• Separate cable installation
• Future cable capacity
• Organized underground routing
• Easier maintenance access
• Consolidated duct infrastructure

Instead of designing each cable route around a completely separate outer duct, the project can use a multi-subduct arrangement where appropriate.

The final selection should be based on cable requirements, available duct capacity, route conditions, installation methodology, and project engineering requirements.
