HDPE Corrugated Duct

Introduction- Aramco 110mm HDPE COD

The Aramco 110 mm HDPE COD is the state-of-the-art multi subduct ducting material for efficient installation and protection of the telecommunication, fibre optic and other underground cables. The system consists of a lightweight outer system built from HDPE with a diameter of 110 mm and five inner ducts of a diameter of 33.9 mm each. Each duct consists of a pulling rope.

The inner surface of each duct comprises a silicon layer, which makes it smooth for placing cables. The five ducts are colour coded and therefore they are very easy to maintain and track in the future.

Therefore, due to the presence of multiple ducts, pulling ropes, silicone layer, and colour codes it has become possible to create a good multi-duct system for effective underground installations.

Product Overview

The Aramco 110mm HDPE COD x 5 Lines 33.9mm O.D. facilitates the combination of a 110mm outer HDPE duct and five individual subducts of a dimension of 33.9mm O.D.
There is a separate pull rope for every individual subduct, which allows for the separate installation of cables through each of its circuits.
The inside surface is tiled with silicon, and this ensures the provision of special features in the internal surface for cable installation.

The color of the outer duct is orange and the internal subducts are made available in various colors.
The details of the subducts are as follows:
1 red subduct
1 green subduct
1 blue subduct
1 yellow subduct
1 white subduct
This means that five separate paths are provided at the same time through one outer duct of 110mm.

Therefore, the Aramco 110mm HDPE COD clearly offers the possibility for organized network building, providing several cable routes being installed in the single coordinated duct system.

Key Features

1. 110mm Orange HDPE Outer Duct

The product employs a 110mm outer duct made from orange HDPE material, which consists of five subducts.

2. Five 33.9mm O.D. Subducts

To complete the system, it uses five subducts with the external diameter of 33.9mm.

3. A Separate Pull Rope for Each Subduct

Every individual subduct comes with pull rope, enabling independent installation of cables across the various pathways.

4. A Layer of Silicon over the Inner Wall

A layer of silicon is placed on the interior of a subduct enabling smooth installation of cables over the inner wall of the individual subducts.

5. Different Colors for Each Subduct

Each of the five subducts is made in a different color, which simplifies identification as the installation process is ongoing.

6. Use of Orange for the Outer Duct

The outer duct is manufactured from orange HDPE and can easily be distinguished from the inner ducts.

7. Five Different Internal Pathways

The five individual subducts make it possible to keep an independent cable or network pathway from each other.

8. Multi-Subduct Configuration

The arrangement of multi-subducts contributes to the effective quality of cable routing.

Technical Specifications

Technical note: Wall thickness, internal diameter, pull-rope specification, silicon-layer characteristics, dimensional tolerances, mechanical properties, coil length, operating temperature, and other performance parameters should be confirmed from the applicable technical datasheet or project specification.

Understanding the 5 × 33.9mm Configuration

The 5 × 33.9mm configuration means that the 110mm outer duct contains five separate internal subducts, with each subduct having a specified outside diameter of 33.9mm.

The five pathways are color-coded:

This arrangement allows individual cables to be assigned to specific pathways instead of placing all cables into a single open duct.

Silicon Layer on Each Subduct

A key feature of this configuration is the presence of the silicon coating on the interior surface of every subduct.

Smoothness on the inner surface can prove advantageous in terms of installation of cable because it can minimize resistance between cable and subduct surface. The performance of actual cable installation is determined by a number of factors, such as the type and size of the cable, the geometry of the path, the equipment used for installation, the pull tension, bending radius and installation method.

Thus, the internal silicon surface should always be considered part of design for cable installation rather than a replacement for calculation of the path and cable engineering.

Individual Pull Rope in Each Subduct

Every subduct comes with a separate pull rope.

This means that there is a unique route for pulling each cable.

The usage of different pull ropes for each cable installation is especially helpful when:

• Cables are installed separately from each other
• Each cable has its own pathway
• Different sections of the network are installed at different times
• There are plans for future installation of cables
• Contractors need a separate pull-in point for each subduct

Before the installation, the specification of the pull ropes and the maximum pulling loads should be checked against the relevant technical documentation.

Color-Coded Cable Pathway Management

The five subduct colors can be used to identify pathways in a simple way.

According to the project design red, green, blue, yellow, and white subduct color coding provides different designations for cables, services, network sections, or installation stages.

Color coding allows installation crews to:

• Identify pathways efficiently
• Eliminate confusion concerning paths
• Provide cable routing
• Ease maintenance operations
• Plan for oncoming installations
• Organize different network connections.

All color allocation should be in accordance with the cable and pathway identification systems accepted in the project when they exist.

Advantages of Aramco 110mm HDPE COD

Multiple Cable Pathways

Five various subducts create distinct roadways through one outer duct configuration.

Better Pathway Organization

These different subducts promote the segregation of cable systems by avoiding several cables from making use of one common pathway.

Individual Pulling Capability

Every subduct has an independent pull rope, which means that each one of them can be used for cable pulling.

Improved Pathway Identification

The color arrangement of red, green, blue, yellow, and white helps to identify every subduct.

Silicon-Coated Internal Surface

The application of the silicon coating ensures the creation of a smooth inner surface of each subduct that contributes to effortless installation of cables into it.

Efficient Use of Underground Space

There are five cable roads incorporated within the limitations of a single outer duct with a diameter of 110 mm, which results in the existence of one simplified solution.

Future Network Flexibility

The unused subducts can serve as future pathways provided that they are in accordance with the capabilities of the project.

Easier Maintenance Planning

Having different pathways with the help of color arrangements makes it easier to detect any cables that need to be checked, changed, and upgraded.

Applications

The Aramco 110 mm HDPE COD is suitable for various underground cable infrastructure projects.

Fiber Optic Networks

The subducts can create pathways for fiber optic cable installations.

Telecom Infrastructure

The five-pathway option can be used for commercial telecommunication networks where cable routes operate together in the same duct system.

Broadband Networks

The duct arrangement is suitable for underground broadband infrastructure with properly organized cable placement.

FTTx Infrastructure

The configuration with multiple subducts may be useful for various components of optical access infrastructure and the overall system design.

Communication Networks

It’s applicable for places where the underground route is necessary for communication cables.

Big Infrastructure Projects

Multi-subduct cable duct systems can be used in large-scale projects, where proper underground communication utility systems are necessary.

Why Use a Five-Subduct Configuration?

A five-subduct arrangement can be useful when a project needs multiple dedicated cable pathways but wants to consolidate them within one outer duct.

Instead of installing five completely separate outer ducts, the five pathways are grouped within a single 110mm outer duct.

This can support:

• Organized cable routing
• Clear pathway identification
• Independent cable installation
• Future cable capacity
• Simplified route planning
• More structured maintenance

Whether this configuration is appropriate depends on the project’s cable requirements, available space, installation method, and approved design.

Aramco 110mm HDPE COD for Underground Infrastructure

The underground cable system needs to be planned extraordinarily because cable size, duct length, installation equipment, and the future needs of the network have to be considered.
The 110mm HDPE COD series by Aramco contains five separate identifiable subducts in one 110mm outer duct that are individually equipped with a pull rope and a layer of silicon on their inner surfaces to enable installation in an organized manner.
The five colors can also be used during construction and maintenance to differentiate the path ways.
