LUOYANG DAĦAL ENERĠIJA TECH CO, LTD

X'inhuma l 5 Tipi ta' Pajpijiet?
Fis-sistema tal-provvista tal-ilma u tad-drenaġġ, Inġinerija HVAC u sistema ta 'pipeline industrijali, l-għażla tal-materjali tal-pipeline taffettwa direttament is-sigurtà, durabilità u kosteffettività tal-proġett. Bħala l-manifattur tal-pajpijiet ewlieni miċ-Ċina, we are well aware of the confusion our customers face when it comes to selection. We will in-depth analysis of the characteristics of PVC pipe, PEX pipe, Pajp PPR & PE pipe, to help you make accurate decisions.

PVC Pajp & Fitting: The King of Ċost-effective General Ċhoice
PVC (klorur tal-polivinil) 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.
Ċharacteristics and Advantages
Strong corrosion resistance: Can withstand pH 2-12 chemical media, suitable for sewage discharge system
Lightweight design: 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
Economical: the price is only 1/3 of the galvanized steel pipe, and the service life is 50 snin
Applications
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 inkroċjat) pipes achieve molecular restructuring through radiation cross-linking technology, creating a flexible revolution in the pipeline industry.
Ċharacteristics and Advantages
| Parameters | Ordinary PE tube | PEX Pipeline |
| Temperature range | – 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 times
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
Pajp 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:Invisible Ċhampion of Underground Engineering
PE (polyethylene) 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 times pipe diameter
Welding technology: the strength of the joint reaches more than 90% of the pipe body
Intelligent tracer system: built-in metal wire, positioning accuracy of ±15cm
Ċharacteristics and Advantages
| Specifications | DN20 | DN160 | DN630 |
| Ring Stiffness | SN4 | SN8 | SN16 |
| Working pressure | 0.6 MPa | 1.0 MPa | 1.6 MPa |
| Applicable scenarios | Indoor water supply | Municipal water supply | Gas delivery |
The Pipes Performance Ċomparison
| Parameters | PVC pipe | PEX pipe | PPR tube | PE tube |
| Max. Temperature | 60 ℃ | 95 ℃ | 95 ℃ | 40 ℃ |
| Compressive strength | 15MPa | 25MPa | 20MPa | 10MPa |
| Thermal conductivity | 0.15 W/mK | 0.35 W/mK | 0.24 W/mK | 0.42 W/mK |
| Environmental rating | NSF61 | NSF61 | NSF51 | NSF61 |
| Service life | 50 snin | 50 snin | 50 snin | 50 snin |

Conclusion ta Engineering Selection
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
