Description

　　Product Introduction

Chlorinated Polyvinyl Chloride (PVC-C) pipes for sprinkler fire extinguishing are specifically designed for building automatic sprinkler fire extinguishing systems. They have obvious advantages such as simple installation, high reliability, a service life of up to 50 years, and low overall cost. They also feature high strength, excellent water pressure characteristics, good fire resistance, no scaling, and low friction resistance.

　Product Features

1. Only simple installation tools or equipment are needed, making transportation easy; no off-site prefabrication is required, resulting in a cleaner and more efficient installation process.

2. The one-step connection system can reduce labor costs. The smooth inner surface creates better water flow performance, reduces pipe size, thereby lowering material costs.

3. Lightweight pipes can enter narrow spaces faster, easier, and quieter, allowing wall panel installers, scaffolders, and other mechanical contractors to work more efficiently and significantly improve productivity.

4. Twelve out of thirteen environmental categories outperform steel systems (including impacts of climate change, metal consumption, and energy consumption).

5. The limiting oxygen index of chlorinated polyvinyl chloride (PVC-C) pipes for sprinkler fire extinguishing is 60, classifying it as a Class A non-combustible product. It produces only a minimal amount of gas when burned, equivalent to the gas produced when wood burns.

　Application Fields

Chlorinated Polyvinyl Chloride (PVC-C) pipes for sprinkler fire extinguishing are widely used in firefighting, industrial hot and cold water systems, direct drinking water systems, seawater transport, electric cable protection sleeves, food processing, and medical applications.
