4 Applications of PVC Pipes

Polyvinyl chloride (PVC) is a synthetic thermoplastic produced by polymerizing vinyl chloride. This plastic is used to make various products, including PVC floors, sheets, and pipes. PVC has many uses, and applications for PVC pipes in Dubai include sewage, drainage, agriculture, and water supply. The uses of PVC are described in more detail here.

1. Potable Water Distribution at Home

Chlorinated PVC or CPVC pipes are safe for potable water supply applications. It can withstand higher temperatures than ordinary PVC, significantly reducing the risk of chemicals leaching into drinking water.

CPVC also has a high biofilm resistance. Biofilm is a slimy substance that can coat surfaces and harbor harmful bacteria like E. coli and Legionella. Due to their low potential for biofilm formation, CPVC pipes reduce the risk of bacterial infection and toxin contamination from drinking water supplies.

2. Industrial Water Supply

Unplasticized PVC or PVC-U pipes are used in water treatment facilities to transport and distribute treated and cleaned water. They are also used to transport wastewater and to deliver water to cooling systems.

PVC-U pipes have municipality water supply applications. PVC pipes primarily comprise main water and service lines.

CPVC is more suitable for drawing out and transporting hot water in industrial plants. CPVC pipes also have excellent resistance even to aggressive chemicals, making them ideal for transporting chemicals, chemically treated substances, and other potentially corrosive materials.

Molecularly oriented PVC or PVC-O pipes have a higher pressure rating and impact resistance than PVC-U pipes. They are useful in high-pressure water transport, especially since PVC-O pipelines are more resistant to water hammer damage. Additionally, PVC-O pipes make an excellent material for transporting filtered water from desalination plants.

High-impact, unplasticized PVC pipes (i.e., high-impact PVC-U pipes) are highly flexible with high resistance to hydraulic pressure, external pressure, and impact. These characteristics make them suitable for various industrial applications, including those that employ PVC-U, CPVC, and PVC-O pipes.

3. Irrigation and Agriculture

PVC pipes are excellent for agricultural irrigation applications. Ordinary PVC pipes are suitable for buried irrigation systems. They are also ultraviolet (UV) resistant, so you can install them above ground. However, it may be best to protect above-grade PVC pipes from UV light-induced degradation by painting them with UV-resistant industrial coating. Alternatively, you may choose high-impact PVC pipes for above-ground installations.

The following are some specific applications of PVC pipes in irrigation and agriculture:

• Mains and submains: PVC pipes make good main and submain pipes in irrigation systems due to their consistent flow rates. Main lines transport water from the source to submains, while submain pipes deliver water from the mains to lateral lines, which supply water to irrigation heads.
• Drip irrigation: PVC pipes supply water to drip lines; they may also serve as actual drip lines. Drip irrigation is an irrigation system characterized by pipes buried under the soil, set on the soil surface or placed just above it. They drip water slowly but consistently onto the soil.
• Sprinkler irrigation: PVC pipes can transport water from service lines to high-pressure sprinkler heads or guns. You need PVC pipes with high hydraulic pressure resistance for sprinkler systems.
• Subsurface irrigation: PVC pipes may be buried below the soil and used to deliver water directly to plant roots.
• Hydroponic systems: Hydroponic systems grow plants on enriched water instead of soil. You can utilize PVC pipes in water circulation systems, as nutrient delivery pipes, and as channels for growing plants.
• Portable watering systems: Portable watering systems are useful for seasonal irrigation demands. Because PVC pipes are lightweight and straightforward to cut, they are a suitable material from which to craft portable watering systems. You can easily disassemble and store the pipes when the need has passed.

4. Sewage and Drainage

PVC pipes are excellent piping materials for sewage and drainage lines because of their corrosion resistance, longevity, smooth inner walls, and ease of installation. You may use PVC pipes in the following sewage and drainage applications:

• Main sewage pipes: PVC pipes can serve as the primary conduits between sewage sources (e.g., residences, commercial establishments, and industrial plants) and sewage treatment plants.
• Secondary sanitary sewer lines: PVC pipes can serve as secondary sewage lines. These sanitary water lines transport waste from toilets, bathroom drains, sinks, dishwashers, washing machines, and other black and greywater sources to main sewage pipes.
• Vent stacks: Vent stacks may be made of PVC pipes. Vent stacks are the vertical pipes that connect to plumbing traps, providing necessary ventilation and ensuring the traps retain the water seal that prevents sewer gases from rising through the plumbing.
• Sewer relining: In some cases, PVC pipes may be inserted into corroded sewage lines, effectively relining damaged sewage pipes.
• Stormwater and surface water drainage systems: PVC pipes have high flow rates, making them ideal for siphoning storm and surface runoff water away from buildings and structures.

Versatile and Multi-Purpose PVC

PVC pipes are strong, durable and long-lasting thermoplastic pipes. They have many uses, including potable water transport, industrial water supply, irrigation and agriculture, and sewage and drainage.
