Plastic conduit is a protective tubing system typically made of PVC or other non-metallic materials. It is used to house and protect electrical wiring and cables from mechanical damage, moisture, and chemical exposure. Unlike metal conduits, plastic conduits are lightweight, corrosion-resistant, and easy to install, making them ideal for both indoor and outdoor use.
The primary role of a plastic conduit is to act as a shield for electrical wiring systems. It ensures that wires remain intact, organized, and protected from external elements such as water, dust, and physical stress. In many cases, plastic connectors are used to join two conduit sections, while a plastic pipe clamp helps in securing the conduit firmly to walls or ceilings.
There are several types of plastic conduits, each designed for specific environments and requirements:
Rigid Plastic Conduit (RPC): Strong and durable, often used in exposed areas.
Flexible Plastic Conduit: Offers adaptability around corners or confined spaces.
Corrugated Plastic Conduit: Lightweight and flexible, perfect for light-duty applications.
Underground Plastic Conduit: Designed for burial and moisture resistance.
Each type may require specific plastic pipe connectors or plastic pipe clamps for a secure and compliant installation.
Plastic conduits are widely used in various industries and settings:
Residential Buildings: For routing electrical cables safely inside walls or ceilings.
Commercial and Industrial Plants: To manage complex wiring systems.
Telecommunications: For organizing and protecting fiber optic cables.
Automotive Applications: To secure wiring inside vehicles.
Wherever you need organized, protected cabling, plastic connectors and plastic conduit systems provide a reliable solution.
To glue plastic conduits, follow these steps:
Clean the ends of the conduit and the plastic connector to ensure proper adhesion.
Apply a PVC primer to soften the plastic surfaces.
Add PVC cement (glue) to both the conduit end and the connector.
Insert the conduit into the plastic pipe connector and hold for a few seconds until it sets.
This creates a strong, watertight bond ideal for long-term installations.
Cutting a plastic conduit is simple and requires minimal tools:
Measure the length needed and mark the cut line.
Use a PVC pipe cutter, handsaw, or rotary tool for a clean cut.
Deburr the edges using a utility knife or sandpaper.
Insert into the plastic connector or clamp with a plastic pipe clamp to complete the section.
If a plastic conduit is cracked or damaged:
Cut out the damaged section using the method above.
Prepare two replacement pieces slightly shorter than the cut-out.
Use plastic connectors on both ends to join the new piece to the old one.
Apply PVC cement for a permanent fix.
For minor surface cracks, conduit repair tape or epoxy resin may also be used.
Plastic conduits are an indispensable component of modern infrastructure systems, both in terms of durability and functionality. Whether it is a water installation or a cable transportation system, plastic conduits selected in the right diameter and quality provide long-lasting and safe solutions. Auxiliary equipment such as plastic conduit clamps, plastic conduit connectors and spiral pipes should not be neglected to improve system performance and ease of installation.
