IFAN Water Use Threaded PPR Water Pipe Fittings

PPR Water Pipe Fittings: Comprehensive Guide

1. Product Overview

PPR Water Pipe Fittings are specialized components manufactured from Polypropylene Random Copolymer. Specifically designed for potable water systems, these fittings connect PPR pipes through heat fusion technology. As a result, they create permanent, monolithic joints that ensure leak-proof performance in both residential and commercial water distribution networks. Unlike traditional metal fittings, PPR fittings are corrosion-resistant and hygienic. Moreover, they require zero maintenance throughout their 50+ year service life.

4. Installation Technology

Heat Fusion Process:
This installation method utilizes thermal fusion. Specifically, both the pipe end and fitting socket are simultaneously heated to a melting temperature of 260°C ± 5°C. Subsequently, they are joined to form a homogeneous connection that is stronger than the base material.

Step-by-Step Installation:

1. Preparation: First, cut the pipe squarely using a PPR-specific cutter, then deburr the edges and clean the surfaces

2. Marking: Next, indicate the insertion depth using the manufacturer’s gauge

3. Heating: After that, apply heat evenly for the prescribed time, which varies by diameter

4. Joining: Then, connect the components immediately without rotation while maintaining alignment

5. Cooling: Following this, allow for natural cooling without disturbance

6. Testing: Finally, pressure test after complete cooling, which typically takes 2-10 minutes

Quality Indicators:

• Uniform bead formation around the entire circumference
