PPR पाइप र फिटिंग: All Types and Applications
PPR pipes and fittings have become the first choice in construction,पानी आपूर्ति प्रणाली,drainage system. As a professional PPR pipes and fittings manufacturer from China, We will comprehensively analyze the types of PPR pipes and fittings, accessories classification and purchase points, to help you create a safe and reliable pipe system.
PPR Pipe Technical Characteristics
1. सामग्री Advantages
PPR (अनियमित copolymer polypropylene) uses advanced type III polypropylene as raw materials,includes:
तापमान दायरा: -20℃ to 95℃ (instantaneous up to 110℃)
Working pressure: PN10-PN25 (1.0-2.5MPa)
Linear expansion coefficient: 0.15mm/m·k
Thermal conductivity: 0.24W/mk
2. Environmental Certification
According to NSF, WRAS, KTW and other international drinking water certification, lead content < 0.1μg/L, in line with GB/T17219 health standards.
The Main Type of PPR pipeline
Classification By Pressure एलevel
| प्रकारहरू | Working Pressure(Mpa) | अनुप्रयोगहरू | Wall Thickness Range |
| PN10 | 1.0 MPa | Cold water system, low pressure irrigation | 2.0-3.5 mm |
| PN16 | 1.6 MPa | Multistory building water supply system | 2.3-4.2 mm |
| PN20 | 2.0 MPa | High temperature heating, industrial piping | 2.8-5.4 mm |
| PN25 | 2.5 MPa | High pressure steam systems, special industries | 3.5-6.5 mm |
Sort By Function
Cold water pipe (marked by blue line): Suitable for water supply system ≤40℃
Hot water pipe (marked by red line): Withstand 70-95℃ high temperature medium
Antibacterial tube: Add nano silver ion, antibacterial rate > 99%
Oxygen blocking tube: EVOH oxygen blocking layer, oxygen permeability < 0.1g/m³·d
निर्दिष्टीकरण Parameters
Commonly used outside diameter specifications (mm) :
Home decoration: 20, 25, 32 mm
Commercial engineering: 40, 50, 63 mm
Industrial systems: 75, 90, 110 mm

Advantage of PPR Pipeline System
1. Comparison of installation efficiency
Hot melt connection: 15-30 seconds/connector
Traditional threaded connection time: 3-5 minutes/connector
The comprehensive construction efficiency is increased by 60%
2. Service life Comparison
| सामग्री | जीवन प्रत्याशा | Maintenance cycle |
| PPR | 50 वर्ष + | Maintenance-free |
| Galvanized pipe | 15 वर्ष | Annual overhaul |
| Copper pipe | 25 वर्ष | 5 year detection |
3. Cost of PPR Pipe System Analysis
The initial cost is 40% lower than copper tubing
Maintenance costs are reduced by 80%
Combined use cost savings of 65%
Professional Purchasing Guide
1. How to Choose High Quality PPR Pipes And Fittings
Observe the incision: The incision of high quality pipe is smooth and without burrs
Combustion test: No black smoke when burning, transparent melt droplets
Light transmittance: Light opaque design to prevent algae growth
2. Suggestions for PPR Pipe System Build
S5 series (wall thickness 2.0mm) is recommended for cold water system.
S3.2 series (wall thickness 2.8mm) recommended for floor heating system
S2.5 series (wall thickness 3.5mm) should be selected for the main riser of high-rise buildings.
3. Key Point of PPR Pipes And Fittings Installation
Hot melt temperature: 260±5℃
Heating time formula: PPR pipe diameter (mm)/10 x 1.2 seconds
Cooling time: 15 minutes in summer, 30 minutes in winter
