It is also resistant to corrosion, making it a popular choice for many plumbing systems. The 3.5-inch Schedule 40 PVC pipe is available in different diameters. It can be used in applications that require different flow rates and pressures.
Schedule 80 PVC Pipe:
This type of pipe has thicker walls than the Schedule 40 pipe. It is used in applications that require higher pressure. The Schedule 80 PVC pipe is used in industrial and commercial applications. It can handle high flow rates and pressures. The pipe is durable and resistant to rust. It is also resistant to chemicals. This makes it a popular choice for applications with high-pressure requirements. The 3.5-inch Schedule 80 PVC pipe is suitable for water treatment plants, chemical processing, and industrial drainage.
Drainage and Sewer Systems:
3.5-inch PVC pipes are commonly used in residential and commercial wastewater systems. They are used in the disposal of water from sinks, toilets, and showers. These pipes are resistant to corrosion and chemicals, which ensures a long life and clean flow of sewage. These pipes are also used in the transport of sewage to treatment plants.
Ventilation:
These pipes are used in venting sewage gases from the pipes to the atmosphere. They are resistant to rust and corrosion, ensuring a long life. These PVC pipes are also useful in the exhaust systems of vehicles.
Water Supply:
These pipes are used in the transport of potable water due to their smooth surface and resistance to rust and corrosion. This ensures clean water without any contamination. They are also used in irrigation systems, which transport water to different areas, ensuring a steady supply.
Electrical Conduits:
These pipes protect electrical wires from damage due to their strong and rigid structure. They ensure the safe and long-term installation of electrical systems. They are also used in communications and data lines.
Drainage Systems:
These pipes are used in above-ground and underground drainage systems. They are resistant to rust and corrosion, which makes them suitable for drainage systems. They are also used in stormwater management systems.
Lightweight and Durable:
These pipes are light, which makes them easy to transport and install. They are also durable, making them a popular choice for different applications.
Corrosion Resistance:
These pipes resist different chemicals and corrosion, which ensures a long life.
Joint Integrity:
These pipes are connected using solvent welds, which creates a strong and rigid joint. The joint is waterproof and ensures the pipes carry fluids without leakage.
Easy to Install:
These pipes are easy to install due to their light weight and simple joining methods. This makes them a popular choice for plumbers and engineers.
Cost-Effective:
3.5-inch PVC pipes are cheaper than other pipes, making them accessible and popular for different applications.
The application of a 3.5-inch PVC pipe is extensive in different industries, which caters to the need for a durable, lightweight, and corrosion-resistant product. Here are some common usage scenarios:
Sewage and Waste Management
A 3.5-inch PVC pipe is commonly used in waste management and sewage systems. It is used to transport wastewater and sewage in municipal and residential drainage systems. The pipe is preferred for this application because it is resistant to chemical substances and is capable of withstanding various environmental stressors.
Electrical Conduits
The 3.5-inch PVC pipe is used as an electrical conduit to protect and route electrical wiring in residential, commercial, and industrial buildings. It is popular for this application due to its lightweight nature, ease of installation, and dielectric properties.
Water Supply
Due to its ability to withstand water pressure, a 3.5-inch PVC pipe is often used in potable water supply systems. It is used to transport clean drinking water in urban and rural water supply systems.
Irrigation
A 3.5-inch PVC irrigation pipe is also used in agricultural applications. It efficiently transports water to different agricultural areas to ensure adequate water supply to crops.
Construction Applications
These pipes are also used in construction projects. For example, it is used in foundation drainage systems, stormwater management, and as formwork for pouring concrete. Its lightweight nature and ease of handling make it a good choice for construction applications.
HVAC Systems
The 3.5-inch PVC ducting pipe is used in HVAC systems for the efficient transportation of air. Its smooth interior surface minimizes airflow resistance, making it a good choice for heating and cooling systems.
Telecommunications
Telecommunication companies use a 3.5-inch PVC pipe to protect and house fiber optic cables and other communication lines. Its strength and durability ensure the integrity of the cables, thus enabling efficient communication.
Pipe Schedule
The thickness of the pipe wall is determined by the schedule number, which varies according to the pipe's diameter. For 3.5-inch PVC pipe, the most commonly used is Schedule 40 and Schedule 80 PVC. The wall thickness is 0.14 inches for schedule 40 and 0.21 inches for schedule 80. The pressure rating is higher for schedule 80 than for schedule 40. When choosing the pipe, determine the application first, and then choose the appropriate schedule. For example, if a low-pressure application is required, schedule 40 will suffice. But if a high-pressure application is required, then schedule 80 is the better option. The higher the schedule number, the thicker the wall and the higher the pressure rating.
Compatibility and Add-Ons
It is easy to identify a compatible fitting by looking at the outside diameter. The measurement should be taken at the pipe's end, and a fitting with a similar diameter should be selected. The only time the outside diameter will differ is when using slip-on weld fittings, which are specifically designed for welding onto a pipe.
When ordering a 3.5-inch PVC pipe, it is important to ask for additional parts that will be used in the project, such as sockets, couplings, and elbows. This way, one supplier will provide everything needed for the project, which will also make it easier to complete the order.
Pressure Rating
When choosing a PVC pipe for an application, the pressure rating must be checked. This rating indicates the maximum pressure that can be applied to the pipe without causing damage. If the application requires the pipe to be filled with water and moved to a different location, the pressure rating should be at least equal to the maximum pressure expected during transportation. The pressure rating is usually printed on the pipe, so it should be checked before making it water tight.
Q1: What is the lifespan of a 3.5-inch PVC pipe?
A1: PVC pipes can last for up to 100 years. They are durable and resistant to corrosion. However, their longevity will depend on the installation and environmental factors, such as temperature and exposure to ultraviolet light.
Q2: What are the disadvantages of PVC?
A2: Although PVC is a widely used material in plumbing and drainage systems, it has some disadvantages. The major one is that PVC cannot be recycled. Also, when exposed to sunlight, it becomes brittle over time. UV light causes its degradation.
Q3: Is the 3.5 inch PVC pipe good for drinking water?
A3: Yes, it is. A 3.5-inch PVC pipe is suitable for conveying potable water. It does not contain harmful chemicals that may contaminate drinking water. Moreover, it is resistant to corrosion and does not produce leaks.
