Dè a tha nas fheàrr? Pìoba PVC vs Pìoba PEX vs Pìob PPR

Ann an gnìomhachas an latha an-diugh, pìob PEX, Tha raon farsaing de thagraidhean aig pìob PVC agus pìob PPR, an-diugh bruidhnidh sinn air “Mar a roghnaicheas tu a’ phìob?

PVC Water Supply Pipe

Analysis of PVC Pìob agus uidheamachadh

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)

  • Applications

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

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

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

3. Advantages of PVC Pipe and Fitting

tùsail “sandwichpipe 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 Pìob agus uidheamachadh

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, antibacterial rate > 99.99%

2. Installation points

Hot melt parameters:

260±5℃ welding temperature

Heating time = pipe diameter (mm)/20 x 1.5 seconds

Cooling time > Pipe diameter (mm)/10 minutes

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

Flexible PEX Pipe and Fitting

Innovative Application of PEX pipeline

  1. Technological

First generation: Peroxide crosslinking (PEXA)

Generation 2: Silane crosslinking (PEXB)

Electron Beam Irradiation Crosslinking (PEXC) Pìob

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

Solution of Pipe Installation

PVC pipe:

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

Socket depth should be ≥ 1.5 times the diameter of the pipe

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)
