Made of galvanized steel, the EMT conduit provides superior strength and rigidity, making it suitable for installations where the conduit may be exposed to physical stress or mechanical damage. Its robust construction also enhances its resistance to impact, crushing, and environmental hazards, making it a good choice for industrial and commercial applications where the protection of electrical wiring is paramount.

2. Durability: 

EMT electrical conduit, constructed from steel, is renowned for its robust protection and longevity in electrical installations. The steel composition of the EMT conduit provides exceptional strength and durability, making it highly resistant to physical impacts, crushing forces, and environmental factors.

In contrast, PVC electrical conduit, while durable in its own right, may not offer the same level of impact resistance or environmental resilience as steel conduit.

3. Weight and Installation: 

PVC electrical conduit is prized for its lightweight nature, ease of transport, and simple assembly process. It can be easily cut and manipulated using basic tools, which makes it particularly convenient for quick installations, especially in residential or non-industrial settings. Its lightweight properties also contribute to reduced labor and installation time.

On the other hand, EMT electrical conduit is known for its rigidity and initial difficulty in cutting. However, with the appropriate tools and techniques, it is possible to bend the EMT conduit to fit specific installation requirements. Due to its metal composition, EMT conduit is naturally heavier than PVC conduit, which can make handling and transportation more challenging, especially in larger installations.

4. Fire Safety Standards: 

EMT electrical conduit’s steel construction provides enhanced fire resistance when compared to PVC electrical conduit.  Furthermore, the galvanized coating applied to the EMT conduit provides an additional layer of protection against corrosion and heat, further bolstering its fire-resistant properties.

In contrast, PVC electrical conduit has limited fire resistance compared to certain metallic conduit options. PVC is a thermoplastic material that can soften. Some lower-quality or substandard PVC conduits may deform, and even ignite when exposed to high temperatures.

rigid pvc conduit VS flexible pvc conduit

When planning electrical wiring installations, the choice of conduit is an important factor that impacts protection, longevity and cost. Two popular conduit options are rigid PVC conduit and flexible PVC conduit. While both are made from PVC, they differ in key aspects related to strength, installation flexibility and suitability for different environments. In this post, we will provide an in-depth comparison of rigid versus flexible PVC conduit to help you determine the best type for your specific project needs.

Know about Rigid PVC Conduit

What is Rigid PVC conduit?

Rigid PVC conduit, also known simply as PVC conduit, is a durable tubing used for routing electrical wiring in installations. It is made from polyvinyl chloride (PVC), a rigid thermoplastic commonly used in piping and construction due to its advantageous properties.

PVC offers strength and rigidity without being overly brittle. Rigid PVC conduit retains its shape well and will not bend, kink, or compress easily like other materials. This maintains a consistent interior diameter to protect encased wiring.

Its rigidity makes it well-suited to harsh installation environments where physical protection is paramount. PVC conduit withstands weathering, moisture, chemical exposure, impacts and pressures without degrading or losing its protective form.

PVC is non-conductive and corrosion-resistant as well. This adds an essential layer of safety for wiring installations in industrial, commercial and outdoor settings. Neither water nor soil can lead to oxidation or short circuits over time.

Lightweight yet durable, rigid PVC conduit sees wide application everywhere from underground electrical lines to building wiring runs to extension cords for power tools. It meets various industry standards for electrical installation materials and carries approvals for plenum and riser spaces.

Overall, rigid PVC conduit excels at providing robust sheathing for wiring networks. Its stiffness and strength maintain full coverage without weakening in demanding conditions. For applications requiring physical shielding, PVC conduit offers limitless usefulness and longevity.

Know about Flexible PVC Conduit

What is Flexible PVC Conduit?

Flexible PVC conduit shares the base material of rigid PVC conduit but with a key difference – it is formulated to bend and flex rather than maintain a fixed shape. This variant is also commonly called liquid-tight flexible metal conduit.

Like rigid PVC, flexible PVC begins as polyvinyl chloride (PVC). However, plasticizers are added into the compound. Plasticizers act as softening agents that increase the pliability of the PVC without compromising its other properties.

This addition allows the conduit tube to conform to twisting turns and curves yet still offer robust protection. Flexible PVC can coil and unfold smoothly along complex wiring routes.

Where rigid PVC is stiff, flexible PVC bends and shapes easily by hand for installation around corners, obstructions and tight spaces. No specialized heat-shaping or fittings are needed at bend points like with rigid conduit runs.

While flexible, this type of PVC conduit does not kink or collapse in on itself even after repeated bending. It retains an open round channel and remains durable for long-term use in a dynamic setting.

Applications suited to flexible PVC conduit include industrial machinery, mobile equipment, vibrating machinery and locations where periodic cable access is needed. Its flexibility streamlines installations that rigid conduit could not navigate.

The Differeces Between Rigid PVC Conduit and Flexible PVC Conduit

 

Rigid PVC Conduit:

1. Maintains a fixed shape and will not bend or deform easily
2. Provides robust physical protection for wiring
3. Requires precise cutting and joining pieces during installation
4. Best for applications that need maximum durability
5. More suitable for outdoor installations that face weathering
6. Initial material costs tend to be lower

 

Flexible PVC Conduit:

1. Contains plasticizers that allow it to bend and flex into curves
2. Easier to install around corners and obstructions
3. Tolerates vibration and minor impacts better
4. Installation is simpler for complex routing paths
5.Allows for cable runs that may experience dynamic movement
6. Material costs higher than rigid PVC
7.But installation labor reduced with easy bending
8. Total costs may be lower for complicated runs

Factors to Consider When Choosing  Rigid or  Flexible PVC Conduit

Protection Needs
Is the wiring going to be exposed to hazards like impacts, moisture or corrosion? Rigid conduit might be better for maximum shielding in demanding outdoor or industrial settings.

Installation Complexity
How many bends and turns will the routing take? Flexible conduit would make my life much easier if snaking around multiple obstacles. Rigid could mean more fittings and joints to worry about.

Cost Impact
Flexible material is pricier but may save me time in the long run. I’d have to estimate meters needed and calculate fitting costs to see the real cost difference for each job. Small complex jobs might favour flexible conduit.

Code Requirements
Electrical code is crucial – it might specify the type of conduit needed based on environmental or fire protection factors. I’d check with the inspector to stay compliant.

Client Factors
Consider the budget but also my client’s preferrences if they have any. Rigid may provide more long-term reassurance for demanding applications.

Future Access
Will serviceability be needed? Flexible conduit could allow repulling cables without dismantling sections like with rigid bends.

Overall I would look at the job holistically – deciding based on a range of protection, installation and economic variables specific to that application. Consulting with suppliers on the best options also helps make an informed choice as the licensed installer. Safety and code compliance are top priorities in my decision.

In this blog post, we will provide a comprehensive discussion of the differences between PVC conduits and PVC pipes.

Construction and Design

PVC conduits are specifically designed for electrical wiring and are thinner and more flexible than PVC pipes. They are available in different colors, including white, gray, and black, and are intended to protect and direct electrical wires for both underground and above-ground applications. Conversely, PVC pipes are designed for plumbing and water supply purposes. They are generally thicker and more rigid than PVC conduits and are available in a variety of sizes and colors.

Applications

PVC conduits are primarily used for protecting and directing electrical wires for both indoor and outdoor applications. PVC pipes, on the other hand, are intended for transporting fluids, such as water and sewage, and are built to withstand high pressure and temperature.

Material Properties

PVC conduits are designed to be weather-resistant and flame-retardant, ensuring that any electrical wires they contain are protected from the elements. In contrast, PVC pipes are designed to handle pressure and temperature changes, making them ideal for transporting fluids. Additionally, PVC pipes are resistant to corrosion, making them a durable and long-lasting option for plumbing applications.

Installation

PVC conduits are typically installed using specialized tools, such as conduit benders and cutters. The installation process involves running electrical wires through the conduit and securing them in place with fasteners. PVC pipes, on the other hand, are typically installed using PVC glue or a similar adhesive to create a tight seal between joints. PVC pipes are also installed using specialized tools, such as pipe cutters and wrenches.

PVC Pipe Size VS. PVC Conduit Size

Schedule 40 is the most commonly used type of PVC pipe. Here’s a table to illustrate the common sizes:

Standards and Codes

Both PVC conduits and PVC pipes are regulated by different standards and codes depending on their intended purpose. Adherence to these standards and codes is crucial to ensure the safe and effective use of these products. For instance, PVC conduits are typically rated for exposure to sunlight and weather, while PVC pipes are rated for pressure and temperature.

Distance Between Water Pipe and Electrical Conduit

Generally, water, gas, sewer, and all electrical systems need to be segregated and maintained at a specific distance from each other. A minimum horizontal clearance of 12 inches should be observed between electrical conduit systems and parallel water, sewer, or gas lines during installation.

Can I use PVC Pipe for Electrical Conduit?

Typically, standard PVC piping isn’t suitable for use as electrical conduit. Despite their visual similarities, significant distinctions exist that render them incompatible for each other’s purposes:

  1. Fire Resistance: Electrical conduit PVC incorporates fire-retardant qualities absent in conventional PVC pipes. This feature is vital for electrical safety, preventing the spread of fire in scenarios involving overheating or electrical sparks.
  2. Structural Integrity: Electrical conduit PVC tends to be more robust and less prone to brittleness than regular PVC pipes. This enhanced durability ensures that the wires enclosed within remain protected against potential damage from external forces.

  3. Compliance with Safety Regulations: Crucially, building codes mandate the use of designated electrical conduit materials. Standard PVC pipes do not adhere to these stringent safety standards, making them unsuitable for electrical installations.

In conclusion, although PVC conduits and PVC pipes may look similar, they are designed for different applications and have distinct properties. It is essential to understand these differences to ensure that the correct product is used in each situation.
