UPVC (Unplasticized Polyvinyl Chloride) is a widely used plastic material in the construction and plumbing industries. Pipes made from UPVC are known for their durability, corrosion resistance, and cost-effectiveness. They are commonly used for water supply, drainage, and sewage systems. UPVC pipes have become the go-to choice for many applications due to their versatility. Here are some popular types of UPVC pipe as standard in the market:
UPVC Drainage Pipes:
UPVC drainage pipes are specifically designed for the efficient removal of wastewater and stormwater. They are available in different diameters and are known for their high impact resistance and durability. Common applications for UPVC drainage pipes include:
Below-ground drainage systems: The pipes are used to collect and transport surface water runoff and groundwater in urban and rural areas.
Adverse weather conditions: The pipes are resistant to harsh weather conditions and UV radiation, making them suitable for outdoor applications.
Non-pressure wastewater: The pipes are used to convey sewage and greywater in municipal and residential settings.
UPVC Pressure Pipes:
UPVC pressure pipes are commonly used in applications where water needs to be transported under pressure. The pipes are lightweight and easy to handle, making them a popular choice for various applications. They come in different sizes and colors. The pipes are suitable for potable water supply, irrigation systems, and industrial fluid transport.
UPVC Oil Pipes:
UPVC oil pipes are specifically designed for the transportation of oil and are resistant to the corrosive effects of oil products. The pipes have a smooth interior, which minimizes friction and allows for the efficient flow of oil. They are lightweight and easy to handle, making them a popular choice in the oil and gas industry.
UPVC Electrical Conduit Pipes:
UPVC electrical conduit pipes are used in the housing of electrical wiring. The pipes provide a safe and efficient way to protect and route electrical wires in residential, commercial, and industrial settings. The pipes are resistant to corrosion, impact, and UV radiation. They are lightweight and easy to install.
UPVC is a type of plastic widely used in the construction of drainage, sewage, and water pipes due to its high durability, lightweight, and resistance to corrosion. UPVC pipes are commonly used for plumbing and water supply because they are cheaper than other types of pipes and have a long lifespan, which makes them a preferred pipe in construction.
UPVC pipes have different functions depending on the area where they are used. Their features also differ, making them suitable for specific areas of use.
UPVC pipes are widely used in various industries for different applications. Some of their usage scenarios include:
When choosing the best UPVC pipes, the following are some of the key factors to consider:
Application
UPVC pipes are used in different applications. Therefore, it is important to know what the pipe will be used for before buying it. This will make it easier to choose the most suitable UPVC pipe.
Schedule or wall thickness
The thickness of the pipe affects its strength and ability to carry fluid pressure. A thicker UPVC pipe is stronger and can carry more pressure. The schedule number of the pipe indicates its thickness, with a higher number showing a thicker pipe. Buyers should choose a schedule that meets the needs of their application.
UV resistance
If the pipe is to be used in an area where it will be exposed to direct sunlight, it is important to choose a UV-resistant UPVC pipe. A UV-resistant pipe will have a special additive during the manufacturing process to prevent it from breaking down when exposed to sunlight.
Color
UPVC pipes are available in different colors, such as white, gray, and black. The color does not affect how the pipe works, but it can be important for some applications. For example, a black UPVC pipe is preferred when drainage is needed, while a white one is used for plumbing and irrigation.
Accessories
UPVC pipes are joined using solvent cement or mechanical fittings. Solvent cement is less expensive and provides a permanent, leak-free joint. However, it can only be used in areas without pressure water. Mechanical fittings are more expensive, but they can be used in any situation and allow disassembly if needed.
Q1. What does UPVC stand for?
A1. UPVC stands for unplasticized polyvinyl chloride. This is a type of plastic commonly used in the construction of drainage pipes, windows and doors.
Q2. What are the standard sizes of UPVC pipes?
A2. UPVC pipes come in different sizes depending on their use. For example, plumbing pipes used in water transport systems have a diameter of between 20mm to 110mm. On the other hand, drainage pipes have a diameter of between 160mm to 200mm. The pipes also have different lengths, with standard lengths of 3 meters and 6 meters.
Q3. What are the disadvantages of UPVC?
A3. Even though UPVC is widely used in construction, it has some disadvantages. UPVC cannot be recycled easily, which poses an environmental challenge. Pipes made from UPVC also become brittle at low temperatures. As a result, they are not suitable for use in cold regions.
Q4. Which is better, CPVC or UPVC?
A4. Both UPVC and CPVC have advantages and disadvantages. Unlike UPVC, CPVC contains a chlorinated element, which makes it suitable for use in hot water transport systems. However, it is more expensive than UPVC and has a lower pressure rating.
