とは何ですか 5 パイプの種類?
In water supply and drainage system, HVAC engineering and industrial pipeline system, the selection of pipeline materials directly affects the safety, durability and cost effectiveness of the project. As the leading pipe manufacturer from China, we are well aware of the confusion our customers face when it comes to selection. We will in-depth analysis of the characteristics of 塩ビパイプ, PEX pipe, PPRパイプ & PEパイプ, to help you make accurate decisions.

PVC パイプ & Fitting: T彼 King of COST効果のある General Choice
PVC (ポリ塩化ビニル) 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 あ利点
強い耐食性: 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 年
あアプリケーションs
Building drainage system (DWV system)
Municipal storm water network
Agricultural irrigation works
Chemical medium transportation (CPVC high temperature resistant model should be selected)
PEX Pイペ & Fitting: Revolutionary Breakthrough of Flexible Pイペ
PEX (架橋ポリエチレン) pipes achieve molecular restructuring through radiation cross-linking technology, creating a flexible revolution in the pipeline industry.
Characteristics and あ利点
| パラメータ | Ordinary PE tube | PEX Pipeline |
| 温度範囲 | – 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 回
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
PPRパイプ: 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 Pイペ & Fitting:私nvisible Champion of Underground Engineering
PE (ポリエチレン) 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 パイプ直径の倍
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
Characteristics and あ利点
| 仕様 | DN20 | DN160 | DN630 |
| Ring Stiffness | SN4 | SN8 | SN16 |
| 使用圧力 | 0.6 MPa | 1.0 MPa | 1.6 MPa |
| 該当するシナリオ | Indoor water supply | 市営水道 | Gas delivery |
The Pイペs Pパフォーマンス C比較
| パラメータ | 塩ビパイプ | PEX pipe | PPR tube | PE tube |
| マックス. Temperature | 60 ℃ | 95 ℃ | 95 ℃ | 40 ℃ |
| 圧縮強度 | 15MPa | 25MPa | 20MPa | 10MPa |
| 熱伝導率 | 0.15 W/mK | 0.35 W/mK | 0.24 W/mK | 0.42 W/mK |
| Environmental rating | NSF61 | NSF61 | NSF51 | NSF61 |
| 寿命 | 50 年 | 50 年 | 50 年 | 50 年 |

結論 の 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
