PPR pipes and fittings have become the first choice in construction,water supply system,ko ya drenaje. 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. Material Advantages
PPR (random copolymer polypropylene) uses advanced type III polypropylene as raw materials,includes:
Temperature range: -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 Level
| Types | Working Pressure(Mpa) | Aplicaciones | 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
Specification 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
PPR Fittings Complete System
1. Connecting Aaccesorios
| Type | Angle Specifications | Nt'ot'es |
| ELBOW | 45 °/ 90 ° /180 ° | Reroute |
| EQUAL COUPLING | Equal diameter pipes are connected in straight lines | |
| REDUCING COUPLING | Reducing range ±50% | Different pipe diameters are connected |
| UNION | Detachable design | Equipment access interface |
2. Branch Aaccesorios
Tee: Equal diameter/reducing diameter, T /Y shunt
Four-way Cross: Cross pipe connection
Multi-Cross: Integrated distribution system
3. Control Aaccesorios
Ball valve: DN15-DN100 full flow control
Globe valve: precise flow control
Temperature control valve: automatically adjust the medium temperature
4. Special Function Aaccesorios
| Types of accessories | Core technology | Functional features |
| Filter Valve | 100 mesh stainless steel strainer | Intercepting pipe impurities |
| Pressure reducing valve | Diaphragm type pressure regulator | Stabilizing system pressure ±0.05MPa |
| Silencer tube fitting | Spiral diversion design | Noise reduction 15-20 dB |
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
| Material | Life expectancy | Maintenance cycle |
| PPR | 50 ya je̲ya + | Maintenance-free |
| Galvanized pipe | 15 ya je̲ya | Annual overhaul |
| Copper pipe | 25 ya je̲ya | 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 Instalación
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
