Mana yang Lebih Baik? Pipa PVC vs Pipa PEX vs Pipa PPR

Dalam industri modern, pipa PEX, Pipa PVC dan pipa PPR memiliki berbagai macam aplikasi, hari ini kita akan membahas “Bagaimana memilih pipa?”

Perbandingan dari Core Parameter

▲ Collation of laboratory data according to ASTM standards

Analysis of PVC Pipe and Fitting

1. Technical breakthrough point

Enhanced formula: The use of calcium zinc stabilizer instead of traditional lead salt formula, through the NSF 61 drinking water certification

Improved impact resistance: Add 5% acrylic elastomer, drop hammer impact strength of 20kJ/m² (ASTM D2444)

• AplikasiS

Rekayasa kota: Drainage main pipe with a diameter of more than 300mm

Irigasi pertanian: UV anti-aging formula pipeline (add 2% carbon black)

Kimia: CPVC corrosion resistant variant (suitable for pH 113)

3. Advantages of PVC Pipe and Fitting

Asli “sandwich” pipe wall structure: inner and outer antibacterial layer + middle strengthening layer

Production accuracy: diameter tolerance ±0.15%, ellipticity ≤0.5%

Testing standard: Passed the ISO 44222:2007 burst pressure test

Analysis of PVC Pipe and Fitting

1. Material revolution

Fourth generation β crystal PPR: thermal deformation temperature increased to 135℃ (25℃ higher than the traditional)

Nano antibacterial layer: composite silver ion coating, tingkat antibakteri > 99.99%

2. Installation points

Hot melt parameters:

260±5℃ welding temperature

Heating time = pipe diameter (mm)/20 X 1.5 detik

Cooling time > Diameter pipa (mm)/10 menit

3 Special application scheme

Hospital hot water system: S4 grade pipe (wall thickness 3.7mm) bearing 2.5MPa

Ground source heat pump system: compound pipe with EVOH oxygen blocking layer

Innovative Application of PEX pipeline

1. Technological

First generation: Peroxide crosslinking (PEXA)

Generation 2: Silane crosslinking (PEXB)

Electron Beam Irradiation Crosslinking (PEXC) Pipa

2. Frontier technology

Intelligent memory pipe: 20℃ environment still maintain flexibility

Oxygen blocking composite pipe: aluminum layer thickness 0.2mm, oxygen transmittance < 0.1g/m³

3. Engineering case

Burj Dubai water supply system: Use PEXALPEX composite pipe, pressure 10bar

Nordic floor heating project: φ16mm pipe laying spacing 75mm, surface temperature difference < 0.5℃

Selection of Pipe decision

1. Water temperature < 60℃ → PVC is the best cost-effective

2.6095℃ hot water → Select PPR (preferred β crystal)

3. Floor heating/complex wiring → PEX flexible piping

4. Drinking water system → PPR nanoantibacterial tube

5. Corrosive media → PVC/CPVC special pipe

Global certification comparison table

Our company qualification: At the same time holds WRAS, UL, W270 and other 12 international certifications

Solution of Pipe Installation

pipa pvc:

Check if the adhesive is expired (shelf life < 6 months after opening)

Socket depth should be ≥ 1.5 kali diameter pipa

PPR hot melt deformation:

Use a welder with digital display temperature control

Extend the cooling time by 30% when the ambient temperature is < 5℃

PEX pipe fittings fall off:

Use brass clamps instead of plastic clamps

Bend radius > 6x diameter pipa (PEXA)
