1. What is PVC?
Before diving into the specifics of AS/NZS 1477 PVC Pipe and fittings, let’s clarify what PVC is. PVC is a type of plastic made from the polymerization of vinyl chloride. It’s lightweight, strong, and resistant to corrosion, making it ideal for a wide range of applications.
1.1 Characteristics of PVC
- Durability: PVC pipes can last for decades without deteriorating.
- Lightweight: Easier to transport and install than metal pipes.
- Chemical Resistance: They are resistant to many chemicals, making them suitable for various environments.
2. Types of AS/NZS 1477 PVC Pipes
2.1 PVC Pressure Pipes
These pipes are designed to handle pressurized water systems. They are typically used in:
- Potable Water Supply: Safe for drinking water.
- Irrigation Systems: Effective for agricultural applications.
2.2 PVC DWV Pipes
DWV stands for Drain, Waste, and Vent. These pipes are essential for:
- Wastewater Removal: Carrying sewage and wastewater away from buildings.
- Venting: Allowing air to enter the plumbing system to prevent vacuum.
2.3 Schedule 40 and Schedule 80 PVC Pipes
These classifications refer to the thickness of the pipe walls:
- Schedule 40: Commonly used in residential applications, handling moderate pressure.
- Schedule 80: Thicker walls provide greater strength for high-pressure applications, often used in industrial settings.
3. PVC Fittings: An Overview
Fittings are crucial components that connect various lengths of pipe. They come in different shapes and sizes to accommodate various plumbing needs.
