What is Schedule 80 PVC Conduit?

Schedule 80 PVC conduit is a type of pipe made from polyvinyl chloride (PVC) with a thicker wall compared to standard Schedule 40 PVC conduit. This increased wall thickness makes it more robust and suitable for applications requiring higher crush resistance and pressure rating.

Here’s a breakdown of key points about Schedule 80 PVC conduit:

  • Material: Polyvinyl Chloride (PVC)
  • Wall thickness: Thicker than Schedule 40 PVC conduit, offering greater strength.
  • Applications: Used for protecting electrical wires and cables in demanding environments where higher impact resistance and pressure rating are necessary. Common applications include:
    • Underground installations
    • Concrete slabs
    • Areas with high foot traffic or exposure to heavy machinery
    • Industrial settings

Properties of Schedule 80 PVC Conduit:

  • Durability: Due to the thicker wall, it can withstand greater impact and crushing force compared to Schedule 40.
  • Corrosion resistance: Inherently resistant to corrosion, making it suitable for both indoor and outdoor use.
  • Lightweight: Even with the increased wall thickness, PVC remains a lightweight material compared to metal conduit options.
  • Ease of installation: PVC can be easily cut, drilled, and glued using solvent cement, simplifying installation.

When is Schedule 80 PVC Conduit Required?

Schedule 80 PVC conduit is generally required in situations where the conduit will be exposed to harsh environments or subject to physical damage.

Some common situations where Schedule 80 PVC conduit may be required include:

Outdoor installations: Schedule 80 PVC conduit is often required for outdoor installations because it is more durable and resistant to weathering than Schedule 40 PVC conduit.

Chemical exposure: Schedule 80 PVC conduit is more resistant to chemical exposure than Schedule 40 PVC conduit, making it a better choice for installations in areas where it may be exposed to chemicals.

Buried installations: Schedule 80 PVC conduit is more resistant to crushing and damage from soil and rocks than Schedule 40 PVC conduit, making it a better choice for buried installations.

High temperature environments: Schedule 80 PVC conduit can withstand higher temperatures than Schedule 40 PVC conduit, making it a better choice for installations in areas where temperatures may be high.

Ultimately, the decision to use Schedule 80 PVC conduit will depend on the specific requirements of the installation and any applicable codes and regulations. It’s always best to consult with a licensed electrician or other qualified professional to determine the appropriate type of conduit for a given installation.
