📏 Size, Thickness and Weight Guide for PVC-U Pipe – Viet Sunrise Plastic JSC
When choosing PVC-U pipe, users often face difficulties in determining the appropriate size, thickness, and weight. With over 20 years of experience in the industry, Viet Sunrise Plastic JSC would like to share a detailed guide to help you select the right type of pipe that ensures safety while saving costs.
🔹 How to Read PVC-U Pipe Sizes
- PVC pipes are usually measured in inches (e.g., 1/2″, 3/4″, 1″…).
- In practice, workers also refer to them as “hun”. For example:
- 1/2″ is called “4 hun”
- 3/4″ is called “6 hun”
- 1″ is called “8 hun”
- Each Viet Sunrise Plastic JSC product has technical specifications printed on it, such as: outer diameter (OD), class, year of manufacture.
🔹 Class (Pressure Rating) of PVC-U Pipe
PVC pipes are classified by class to indicate their water pressure resistance. Common types include:
- Class 5 – low pressure (~5 bar). Suitable for indoor drinking water systems (1.5 – 2 bar).
- Class 8.5 – medium pressure. Often used for outdoor installations, buried applications, and domestic water supply systems.
- Class 13.5 – high pressure. Suitable for large projects, main pipelines, or areas with high pressure.
💡 Advice from Viet Sunrise Plastic JSC: Choose the right class from the start. If used indoors, class 5 is sufficient. If used outdoors or buried, prioritize class 8.5 or 13.5 for long-lasting systems.
🔹 Lifespan of PVC-U Pipe
If you choose pipes that meet quality standards and are installed correctly, products from Viet Sunrise Plastic JSC can last over 50 years. This is a safe and cost-effective choice for any project.
