Izay no tsara kokoa? PVC Pipe vs PEX Pipe vs PPR Pipe

Amin'ny indostria maoderina, PEX pipe, PVC sodina sy PPR sodina manana isan-karazany ny fampiharana, androany isika dia hiresaka momba ny "Ahoana no fomba hifidianana ny fantsona?”

Comparison nY Core tarameters

▲ 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)

• Fampiharanas

Municipal engineering: Drainage main pipe with a diameter of more than 300mm

Agricultural irrigation: UV anti-aging formula pipeline (hametraka 2% carbon black)

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

3. Advantages of PVC Pipe and Fitting

tamin'ny fototra “sandwich” pipe wall structure: inner and outer antibacterial layer + middle strengthening layer

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

Testing standard: Nandalo ny 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, tahan'ny antibaktera > 99.99%

2. Installation points

Mafana levona masontsivana:

260±5℃ welding temperature

Heating time = pipe diameter (MG)/20 x 1.5 segondra

Cooling time > Pipe diameter (MG)/10 minitra

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 nypplication of PEX pipeline

1. Technological

First generation: Peroxide crosslinking (PEXA)

Generation 2: Silane crosslinking (PEXB)

Electron Beam Irradiation Crosslinking (PEXC) sodina

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

PVC pipe:

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

Socket depth should be ≥ 1.5 ny savaivony ny sodina

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 pipe diameter (PEXA)
