Key Features & Benefits of EB-20 PVC Duct Bank Pipes

Concrete Encased System Ready

EB-20 PVC ducts are specifically engineered to be encased in concrete for maximum structural protection. The concrete provides load bearing support against soil pressure and heavy vehicle loads.

Durable PVC Construction

Manufactured from high modulus PVC that is impact resistant, moisture-proof, corrosion resistant and lightweight, making it ideal for underground installations.

Bell-End for Quick Connections

Each length typically features a factory-formed bell-end connection for fast and secure solvent-weld joining without additional fittings.

Thermal and Electrical Cable Rated

EB-20 PVC ducts are rated for 90 °C cable systems used in modern power distribution and communications infrastructure.

Standards Compliance

Conforms to high industry standards:

  • ASTM F512 (non-metallic conduit standard)

  • NEMA TC-6 & TC-8 (utility duct performance)

  • ETL Listed or UL651 in some variants

Long Life Expectancy

Excellent resistance to soil gases, moisture and chemicals—making it durable even in the Gulf’s aggressive soil and coastal environments.

Easy Handling & Installation

PVC material is lightweight and easy to cut, bend and solvent weld which accelerates field installation.

Material & Manufacturing Standards

The knowledge of the standards that define EB-20 PVC duct bank pipe draws the line upon which the specification compliance for tenders and infrastructure projects in the GCC region is built:

ASTM F512

As a matter of fact, this is the foremost American standard for PVC power and communication ducts that gives assurance that non-metallic conduits comply with quality, mechanical strength, and performance as per the set standards.

NEMA TC-6 & TC-8

These standards classify electrical PVC ducts with regard to their performance based on the criteria of wall thickness, impact strength and environmental resistance.

UL651 / ETL

This is a voluntary listing for some PVC duct items that signify extra safety certification for circuits of conduits electrical systems.

The amalgamation of these standards is what makes it possible for a PVC duct to be an option for use in utility, electrical, telecom and fiber optics duct banks and to be laid in engineered works.

How EB-20 Works in a Concrete Encased System

A Concrete Encased Duct Bank System has the following purpose:

  1. It is to support structurally underground utilities.
  2. It is to prevent cables from getting damaged, and, thus, soil movement and heavy loads.
  3. It is to facilitate future cable changes by defining specific duct pathways that will lead to them.

Installation Method :

  • Trenches are made by digging to designed depths
  • A bottom layer of crushed rock or sand is put
  • PVC EB-20 conduit pipes are laid with spacers to keep the pipes in line
  • Reinforcement steel mesh is installed
  • Concrete is cast around conduits to create a duct bank that is hard
  • Maintenance has access through cable pulling eyes or manholes

The concrete encasement keeps the conduit and cables safe from ground movement, moisture, corrosion and physical damage.

Typical Applications Across Sectors

A. Electrical Power Distribution

  • Main and auxiliary electrical feeders, medium and low voltage power cables.

B. Communication Networks

  • Optical fibers, telephone lines, CATV, and Internet infrastructure.

C. Infrastructure Projects

  • Overpasses, highways, airfields, port improvements, subterranean passages.

D. Industrial Facilities

  • Oil and gas processing, chemical manufacturing, electricity generation.

E. Residential & Smart Cities

  • Infrastructure in new urban planned residences.

Besides, all these applications have prevailing PVC duct bank systems, which, apart from providing reliable cable routing, also support future expansion while cutting down excavation and repair costs to the minimum.

Installation Guide for Concrete Encased Duct Banks

Here is a high-level step-by-step guide:

Step 1: Site Survey & Design

Review utility drawings, soil type, load requirements, and cable capacity.

Step 2: Trench Preparation

Excavate trench according to depth and width specified by project engineers.

Step 3: Base Layer Compacting

Place a sand or stone base to prevent pipe abrasion.

Step 4: Laying Conduits

Place 110 mm EB-20 PVC duct pipes with proper spacing and alignment. Use spacers to keep ducts evenly distributed.

Step 5: Reinforcement

Install steel rebar mesh if required by design.

Step 6: Concrete Encasing

Pour concrete ensuring at least 75 mm cover on all sides of the duct.

Step 7: Inspection & Testing

Inspect ducts for alignment, integrity and confirm embedment depth.

Step 8: Cable Installation

Once concrete hardens, cables can be pulled through ducts using cable lubrication and pulling equipment.

Design Best Practices & Gulf Region Considerations

In the Gulf area and KSA, there are some specific aspects that should be taken into account:

 Very hot weather

The PVC duct has to be rated for the extreme heat; the EB-20 cable is rated for a maximum temperature of 90 °C.

 Soil type

The accelerated corrosion of the salt-laden coastal soils makes it the ideal place for PVC with its corrosion resistance.

Sand entering

The use of well-sealed bell ends along with concrete encasement is a method of preventing sand ingress.

Weight

The heavy duty of duct banks encased in concrete is a protection against heavy loads caused by the traffic and industrial operations.

Comparing EB-20 with Other Duct Types

Duct TypeApplicationWall StrengthNotes
EB-20Concrete encasedMediumMost commonly used
EB-35Heavy wall concrete encasedStrongerFor high-impact conditions
