HDPE Double Wall Corrugated Duct 110 mm OD
Specifications, Uses & Telecom Applications in KSA
Why 110 mm OD DWC Duct is Ideal for Gulf Region Projects
The Gulf region is known for:
1. Exceptional heat (generally exceeding 50°C in summer, and sometimes even more)
2. Really high solar radiation
3. High-salt content in soil
4. Extremely high total weight of constructions and other infrastructure
5. Huge fiber optic network installation
The ducting system of 110 mm HDPE Double Wall is designed in such a way that it can endure the extreme conditions and at the same time be efficient:
✔ Heat Resistance
It can withstand ground temperatures of 60°C and installation creates stress.
✔ Sand & Soil Load Resistance
Walls are made in a wave pattern, hence, the weight is shared equally and there is no chance of being crushed.
✔ Chemical & Salinity Resistant
It can be placed in the coastal areas of Saudi Arabia, Oman, Kuwait, and the UAE.
✔ Long Lifespan
The lifespan is more than 50 years, which brings down the maintenance cost greatly.
Key Features of HDPE-Double Wall Corrugated Duct 110 mm OD
1. Dual Layer Construction
- Outer Layer: Strength, provided by corrugated.
- Inner Layer: A smooth bore that lets the cable slide much easier thus reducing cable friction.
2. High Ring Stiffness
- A ring stiff enough to support heavy loads of earth and
- traffic loads resulting from both roads and railways crossing.
3. Lightweight and Flexible
Not only a breeze to transport but also an easy thing to handle, cut, and install.
4. Excellent Chemical Resistance
Totally unaffected by the presence of oils, acids, alkalis, and corrosive soil.
5. UV-Stabilized Material
The duct is already protected against dust and UV rays which means that there will be no degradation even if the duct is stored openly.
6. Rodent & Termite Resistant
Protection for telecom ducts in rural and desert areas is a necessity.
7. Long Length Supply Options
Fewer joints and shorter installation time.

How the 110 mm DWC Duct is Used – Installation Process
1. Trenching
Trenches are excavated based on depth requirement.
Bedding layer (soft soil/sand) is placed for support.
2. Duct Placement
Ducts are laid in straight alignment.
Coils help minimize joints in long-distance projects.
3. Coupling
Snap-fit or push-fit couplers join the ducts securely.
4. Cable Pulling
Smooth inner layer reduces friction.
Nylon or polypropylene rope helps in cable pulling.
5. Backfilling
Sand cushion is added, and trench is refilled with soil.
6. End Cap Usage
Ends are sealed to prevent dust, moisture, and sand entry.

HDPE Double Wall Corrugated Duct 110mm – Industry Insights & Best Practices
To support telecom infrastructure planning and underground network installations, understanding the advantages of double wall corrugated duct systems is essential.
HDPE Corrugated Duct vs PVC Conduit
| Feature | HDPE Corrugated Duct | PVC Conduit |
|---|---|---|
| Flexibility | High flexibility for underground routing | Limited flexibility |
| Impact Resistance | Excellent for heavy load environments | Moderate |
| Installation | Ideal for trenching and duct banks | Often used in rigid installations |
| Lifespan | 50+ years in underground systems | 25–40 years |
Best Industry Practices for HDPE Corrugated Duct Installation
1. Ensure Trench is Prepared
Level out the base of the trench before putting in any outside materials like rocks, etc., to help keep everything from getting damaged on impact.
2. Check the Bend Radius
Ducts may bend in ways, but they still need to meet Council's recommendations for the radius of that bend so as to keep fibre optics safe.
3. Ensure Couplings & Seals Are Compatible
If all joins are made properly then soil will not enter and water doesn't get into the telecom networks.
4. Follow All Project Specs
Telecomm projects (like FTTx deploy) need to use ducts according to Int'l mech/met standards; this includes International Standards as well.
5. Use Detectable Tape
This makes it easy for people excavating in the future to recognize there is some type of an underground telecom infrastructure underneath them.
