Cosa sono i 5 Tipi di tubi?
Nel sistema di approvvigionamento idrico e di drenaggio, Ingegneria HVAC e sistema di tubazioni industriali, la selezione dei materiali della tubazione influisce direttamente sulla sicurezza, durabilità ed efficienza economica del progetto. Come produttore leader di tubi dalla Cina, we are well aware of the confusion our customers face when it comes to selection. We will in-depth analysis of the characteristics of Tubo in PVC, Tubo PEX, Tubo in PPR & Tubo in PE, to help you make accurate decisions.

PVC Tubo & Fitting: TLui King of Cost-effective General Cscelta
PVC (cloruro di polivinile) pipe with its comprehensive advantages, long occupied more than 60% of the water supply and drainage pipe market share, is well-deserved the king of cost performance.
Characteristics and UNvantaggi
Forte resistenza alla corrosione: Can withstand pH 2-12 chemical media, suitable for sewage discharge system
Design leggero: The density is only 1/5 of steel, and the transportation and installation cost is reduced by 40%
Low fluid resistance: Hasson-Williams coefficient 150, energy saving more than 30% than metal pipes
Economico: the price is only 1/3 of the galvanized steel pipe, and the service life is 50 anni
UNapplicazioneS
Building drainage system (DWV system)
Municipal storm water network
Agricultural irrigation works
Chemical medium transportation (CPVC high temperature resistant model should be selected)
PEX Pipe & Fitting: Revolutionary Breakthrough of Flexible Pipe
PEX (polietilene reticolato) pipes achieve molecular restructuring through radiation cross-linking technology, creating a flexible revolution in the pipeline industry.
Characteristics and UNvantaggi
| Parameters | Ordinary PE tube | PEX Pipeline |
| Intervallo di temperatura | – 20 ℃ ~ 60 ℃ | – 40 ℃ ~ 95 ℃ |
| Bursting pressure | 2.5 MPa | 4.0 MPa |
| Bending radius | 8D | 5D |
| Oxygen penetration rate | Acuity 3.0 g/m after · d | 0.1 g/m or less after · d |
Advantage of PEX Pipe Installation
1. No need for hot melt connection: Using clamp type joint, construction efficiency is increased by 3 volte
2. Bending memory function: Can withstand more than 1000 bending without deformation
3. Anti-freeze and crack characteristics: -40℃ low temperature environment still maintains elasticity
Tubo in PPR: The Gold Standard of Healthy Drinking Water
PPR (Random Copolymer polypropylene) pipe is FDA food grade certified and has become the material of choice for healthy drinking water systems around the world.
Health and Environmental Features
Zero heavy metal precipitation: NSF/ANSI 61 drinking water system certification
Antibacterial and bacteriostatic layer: Specially formulated to inhibit the growth of microorganisms such as E. coli
Strong thermal stability: Long-term use of 95℃ hot water without the release of harmful substances
Key Points of Engineering Practice
Hot melt welding process: the welding temperature of 210±5℃ should be strictly controlled
Expansion coefficient management:Linear expansion coefficient 0.15mm/m·℃, need to set compensator
UV protection: Anti-UV modified model should be selected for outdoor installation

PE Pipe & Fitting:IOnvisible Champion of Underground Engineering
PE (polietilene) pipes dominate the underground pipe network market due to their excellent resistance to environmental stress cracking.
Underground pipe network solutions
Trenchless construction: SDR11 series can withstand radial deformation of 3 volte il diametro del tubo
Welding technology: the strength of the joint reaches more than 90% del corpo del tubo
Intelligent tracer system: built-in metal wire, positioning accuracy of ±15cm
Characteristics and UNvantaggi
| Specifiche | DN20 | DN160 | DN630 |
| Ring Stiffness | SN4 | SN8 | SN16 |
| Pressione di esercizio | 0.6 MPa | 1.0 MPa | 1.6 MPa |
| Scenari applicabili | Indoor water supply | Approvvigionamento idrico comunale | Gas delivery |
The PipeS Pprestazione Cconfronto
| Parameters | Tubo in PVC | Tubo PEX | Tubo PPR | PE tube |
| Max. Temperatura | 60 ℃ | 95 ℃ | 95 ℃ | 40 ℃ |
| Resistenza alla compressione | 15MPa | 25MPa | 20MPa | 10MPa |
| Conduttività termica | 0.15 W/mK | 0.35 W/mK | 0.24 W/mK | 0.42 W/mK |
| Environmental rating | NSF61 | NSF61 | NSF51 | NSF61 |
| Vita utile | 50 anni | 50 anni | 50 anni | 50 anni |

Conclusione Di Engineering Selezione
1. Medium characteristics priority: PVC is preferred for corrosive fluids, PPR is required for drinking water systems
2. Temperature and pressure matching: PEX/PPR is selected for high temperature system, and composite pipes are considered for high pressure environment
3. Evaluation of construction conditions: PEX is recommended for small Spaces, and UV-resistant models are selected for open environments
4. Full cycle cost accounting: LCC analysis including maintenance cost and energy consumption cost
