Wat sinn d' 5 Zorte vu Päifen?

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 PVC Päif, PEX Päif, PPR Rohr & PE Rohr, to help you make accurate decisions.

PVC Päif & Fitting: The King of Cost-effective General Choice

PVC (polyvinylchlorid) 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 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 Joer

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 Piep & Fitting: Revolutionary Breakthrough of Flexible Piep

PEX (cross-linked polyethylene) pipes achieve molecular restructuring through radiation cross-linking technology, creating a flexible revolution in the pipeline industry.

Characteristics and Advantages

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

PPR Pipe: 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 Piep & Fitting:echnvisible Champion 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

Characteristics and Advantages

The Pieps Performance Comparison

Conclusion vun 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
