What Is PVC Type DB‑100 Conduit – 50 mm (1½″)?

The PVC Type DB‑100 Conduit – 50 mm (1½″) is a tough and heavy-wall PVC rigid conduit that is suitable for direct underground burial. The conduit has a 50 mm diameter allowing for the passage of larger and more cabling with the utmost safety from the elements and with the entire communication and electric underground infrastructures secured.

The high mechanical strength implied by the DB‑100 class allows for the use of the product in the areas of residential, commercial, municipal, and industrial installations where the need for durability and reliability is high.

Understanding DB‑100 Direct Burial Classification

DB‑100 is a heavy-duty underground duct with a direct burial function, which is resistant against underground pressure and other impacts.

Main Features:

  • Maximum mechanical protection provided by thick walls
  • Can be buried straight away without the need for concrete
  • Soil pressure, minor impact, and moisture are resisted
  • Approved for use in critical infrastructure and utility projects

In the GCC area, DB‑100 pipes are extensively used as the main factors for their selection are durability, long life expectancy, and resistance to harsh environmental conditions.

Why PVC Conduits Are Ideal for Gulf Region Projects

Corrosion & Chemical Resistance

PVC remains non-rusting and unimpaired in salt, alkali, or damp soils, therefore it is a very reliable material in the long run.

Thermal Stability

Remains intact during very high ambient and soil temperatures encountered in Gulf countries.

Electrical Safety

PVC being an insulating material, the chances of stray electrical currents are eliminated.

Lightweight & Easy to Install

Less labor and project costs as the conduits made of metal are more difficult to transport, handle, and install than the ones made of PVC.

Long Service Life

In generally, 30–50 years and in extreme environmental conditions even more.

Material Standards & Compliance

PVC DB‑100 50 mm conduits meet international and regional standards:

  • ASTM D1785 / D2241 – Rigid PVC pipe/conduit standards

  • NEMA TC-6 & TC-8 – Electrical conduit performance

  • IEC 61386 – International conduit system standards

  • UL 651 / ETL (optional) – Electrical safety certification

Key Features & Performance Benefits

  • The hefty wall building is meant to provide the most mechanical protection possible.
  • A 50mm diameter can support several cable runs at once.
  • Besides, the inner surface is smooth which makes it easy to pull the cables through.
  • The material has total resistance against rust, chemical, and moisture exposure.
  • Additionally, it is a non-conductive material which secures the installation.
  • Minimizing concrete for direct burial leads to reducing the installation cost.
  • The long-lasting service life guarantees a high return on investment (ROI).

Typical Applications

  • Industrial: Control, instrumentation, and electrical wiring

How DB‑100 Direct Burial Systems Work

DB-100 conduits are installed in the trenches that are made ready for them, they are connected either with solvent weld or mechanical couplers, and then the soil is filled up again. The conduit acts as a safe and secure route for the cables protecting them from the soil pressure, water, or slight excavation impacts while at the same time allowing for future maintenance or expansion.

Step-by-Step Installation Guide

  • Dig trench to the planned depth
  • If wanted, prepare a smooth soil base (sand bedding is optional)
  • Put DB-100 50 mm pipe in the trench
  • Join sections with solvent weld or mechanical couplers
  • Take the cables in the conduit
  • Soil backfill and compaction
  • Place warning tape over the pipe

Design Considerations for KSA & Gulf Region

  • High ambient temperatures and intense sun exposure

  • Sandy, saline, or alkaline soils

  • Light surface loads (non-traffic or pedestrian areas)

  • Future expansion and spare capacity

  • Compliance with local utility and municipal standards

Accessories & Fittings

  • Solvent weld couplers

  • Mechanical repair couplers

  • 45° and 90° elbows

  • Pulling eyelets

  • Spacer clips and warning tapes

Performance in Harsh Environmental Conditions

  • UV-resistant for storage and handling
  • Moisture, chemicals, and soil contaminants cannot affect resistance
  • Keeps firmness in case of ground settlement
  • Trustworthy in deserts, by the sea, and in cities

Maintenance & Inspection

  • Minimal maintenance required

  • Inspect during excavation or upgrades

  • PVC resists corrosion and rust, reducing long-term costs

Cost Efficiency & Lifecycle Benefits

  • Lower installation costs than concrete-encased ducts

  • Faster installation reduces labor

  • Reduced cable damage risk
