PVC (Polyvinyl Chloride) pipes have become a staple raw material in plumbing and construction industry. As the demand for efficient and reliable pipes is increasing, different types of PVC pipes are filling that market gap. Known for their durability, cost-effectiveness, and versatility, PVC pipes are becoming essential. In this guide, we’ll get to know about various types of PVC pipes, their unique characteristics, and their applications.
Types of PVC Pipes Categories
PVC Pipes have become a norm in the plumbing and infrastructure sector. They are being used in all kinds of structures for the supply of water and the removal of wastewater. They are also actively used in industrial establishments for the transport of other forms of liquids. However, PVC pipes cannot as one size fits all. A little modification to the base material of PVC makes it a multi-utility option. PVC pipes can be categorized on different factors like thickness, properties, and applications.
Types of PVC Pipes Based on Thickness are as follows
- Schedule 40 PVC Pipes
- Schedule 80 PVC Pipes
Types of PVC Pipes Based on Properties are as follows
- U-PVC (Unplasticized PVC)
- C-PVC (Chlorinated PVC)
- O-PVC (Molecular Oriented PVC)
- Modified PVC
Types of PVC Pipes Based on Thickness are as follows
- PVC DWV (Drain, Waste, and Vent) Pipes
- PVC Pressure Pipes
- PVC Electrical Conduit Pipes
- PVC Sewer Pipes
Types of PVC Pipes Based on Thickness
1. Schedule 40 PVC Pipes
Schedule 40 PVC pipes are the most commonly available PVC pipe options in the market. Known for their versatility and durability, they are suitable for a wide range of applications. Schedul 40 PVC pipes have medium thickness and are right for residential and commercial plumbing. They are used for water distribution, drainage, and vent systems. They have a smooth interior which makes it a popular choice for plumbing projects.
2. Schedule 80 PVC Pipes
Schedule 80 PVC pipes have a higher thickness than Schedule 40 PVC pipes. With thicker walls, they can withstand higher pressures and are more resistant to impact and external stress. They are mostly used in industrial and infrastructure settings. They are more suitable for applications in chemical processing, industrial water treatment, and underground installations.
Types of PVC Pipes Based on Material
What are U-PVC Pipes?
U-PVC pipes are the most widely used PVC pipe among different types of PVC pipes. The rigid PVC pipe is made from unplasticized PVC resin. This PVC variant is employed in the transportation of drinking water, wastewater, underground drainage, and industrial applications. They are a preferable choice for plumbing because they are light, affordable, and easy to handle.
U-PVC pipes are highly durable and can last up to 100 years buried underground. They have high resistance to chemicals and UV exposure. Because of these properties, U-PVC pipes are also being used in industrial applications where resistance to chemicals is crucial. They are used to convey a wide range of fluids, including acids and alkalis in industrial facilities and chemical processing plants.
What are C-PVC Pipes?
C-PVC pipes are a variation of PVC pipes. They have enhanced heat resistance, which makes them more suitable for high-temperature water flow in residential and commercial buildings. PVC pipes undergo a chlorination process to build higher resistance to heat. CPVC pipes are the general go-to option for applications like hot water distribution, sprinkler systems, and industrial processes. They have excellent impact resistance and are significantly more ductile than UPVC pipes. CPVC pipes and fittings can be recycled completely.
What are O-PVC Pipes?
Molecularly Oriented PVC (PVC-O) is created using a production method that turns U-PVC (Unplasticized PVC) in the amorphous structure into a layered structure. This modification enhances the features of Plasticized PVC such as corrosion resistance, water quality preservation, cost efficiency, and more.
These pipes are more suitable for high-pressure fluid movement because of their ductility, crack propagation, hydraulic capacity, and impact and fatigue resistance. O-PVC is best suitable for drinking water supply at high pressures. They can also used for non-potable applications such as irrigation and sewer pumping channels. O-PVC pipes and fittings can be completely recycled.
What are Modified PVC Pipes?
As the name says, they are modified versions of other PVC pipes. Modified PVC pipes are formed by the addition of compatible modifying agents to PVC. The additions improve impact properties, toughness, and crack resistance which improves the ductility of the material. The modified PVC can have high strength with thinner walls in comparison to other types of PVC pipes. This results in material savings and higher performance.
Types of PVC Pipes Based on Applications
1. PVC DWV (Drain, Waste, and Vent) Pipes
DWV PVC pipes are designed specifically for drainage, waste, and venting applications. These pipes have thinner walls compared to Schedule 40 PVC pipes, as they are not intended to withstand high pressure. They are crucial for the proper functioning of residential and commercial buildings. They have a smooth interior surface which ensures efficient waste removal and prevents clogs and blockages.
2. PVC Pressure Pipes
The pressure of fluid flow varies in different sections of a pipe network. The entire network cannot be built using a single type of pipe. Hence, PVC pressure pipes are available to handle high-pressure applications like water mains, irrigation systems, and industrial processes. They can be customized based on the specific projects using different pressure-rated pipes. They are durable, cost-effective, and corrosion-resistant. They are better alternatives for iron pipes which have significant exposure to corrosion.
3. PVC Electrical Conduit Pipes
PVC pipes are also used in electrical networks to protect cables and wiring from physical and environmental damage. They are lightweight, easy to install, and offer excellent insulation properties. PVC electrical conduit pipes are commonly used in residential, commercial, and industrial settings to route and protect electrical wiring.
4. PVC Sewer Pipes
PVC Sewer pipes are designed to handle the corrosive and abrasive nature of sewage and industrial effluents. They are resistant to chemicals and biological agents commonly found in sewage systems. They play a vital role in managing sewage and wastewater. PVC sewer pipes are widely used in municipal sewage systems, industrial wastewater management, and residential septic systems.
Conclusion
Different types of PVC pipes have found a wide range of applications in plumbing, construction, electrical, and industrial sectors. There’s a PVC pipe around every element of modern infrastructure. It is crucial to understand the characteristics of different types of PVC pipes to make an informed decision and ensure the success and longevity of projects. Being an eco-friendly choice, PVC pipes provide more sustainable solutions for the future.
Frequently Asked Questions
1. Why do we prefer PVC pipes instead of iron pipes?
PVC pipes are lightweight, resistant to corrosion, and easy to install. They don’t rust, providing a longer lifespan and better durability than iron pipes, and require less maintenance.
2. Which PVC pipe is best for a water supply?
Schedule 40 PVC pipes are commonly used for water supply systems. They are durable, affordable, and suitable for both cold and hot water applications. CPVC pipes are preferred for high-temperature water supply.
