Why HDPE Corrugated Duct 90 mm OD Is Preferred in KSA & Gulf
The Gulf region is characterized by a very specific climate and soil which demand the installation of strong and durable cable ducts. The pipe machine is versatile enough to produce pipes of different sizes, and up to 1,000 mm, the company guarantees that HDPE will outlive both PVC and metal pipes.
- Major Environmental Factors in the Gulf Area
- Extreme summer temperatures of more than 50°C
- Salt and sand desert soil
- Strong UV light exposure
- Roads with heavy vehicular traffic
- Very long infrastructure along the routes
The use of HDPE ducts, in such cases, is advisable because they hold the utmost ductility, offer high thermal-resistance, and do not interact with chemicals. On the other hand, the size of 90 mm OD is acceptable according to the telecom and utility design standards in the region, thus making it one of the most preferred sizes for conduit among the contractors.
Detailed Features & Benefits
1. High Structural Strength
The corrugated outer wall increases mechanical strength without adding weight. This ensures resistance against:
Soil pressure
Surface load from vehicles
Heavy equipment movement
Trench compaction forces
2. Smooth Inner Surface for Easy Cable Installation
While the outer layer is corrugated for durability, the inner layer is smooth, reducing friction during cable pulling and preventing damage to fiber-optic cables.
3. Lightweight & Flexible
HDPE is significantly lighter than metal or PVC conduits. Coil packaging enables easy handling at construction sites, reducing manpower and installation time.
4. Corrosion & Chemical Resistant
In Gulf environments where soil may contain chemicals, moisture, salinity, and hydrocarbons, HDPE corrugated ducts remain unaffected.
5. Long Service Life
HDPE ducts often last 50+ years, offering excellent value for money.
6. Ideal for Direct Burial
Unlike fragile conduits, this duct can be buried directly without requiring extra protection.
7. Suitable for HDD (Horizontal Directional Drilling)
Flexibility and high tensile strength make it suitable for trenchless installations such as:
Road crossings
Railway crossings
Airport zones
Urban underground routes
8. UV-Stabilized Options
KSA and Gulf use outdoor exposed ducts in many projects. UV-stabilized HDPE ensures the duct can remain exposed for extended periods without degradation.

How the Duct is Installed – Complete Usage Guide
1. Ground Preparation
The trench should be clear of sharp stones and properly leveled. Sand bedding is often used to protect the duct.
2. Duct Laying
Coiled ducts are unrolled and laid in straight alignment. Bending is permitted due to high flexibility.
3. Jointing
Special couplers or sleeves are used to connect duct sections securely, ensuring airtight and watertight sealing.
4. Pulling Cables
A smooth-bore interior allows cables to be pulled using winches, lubricants, or blowing equipment.
5. Backfilling
Soft soil or sand is filled first, followed by standard soil compaction.
This process ensures maximum protection, longevity, and project compliance.
