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)
- Өргөдөлс
Municipal engineering: Drainage main pipe with a diameter of more than 300mm
Хөдөө аж ахуйн усалгаа: 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
Original “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, бактерийн эсрэг түвшин > 99.99%
2. Installation points
Халуун хайлмал параметрүүд:
260±5℃ welding temperature
Heating time = pipe diameter (мм)/20 x 1.5 секунд
Хөргөх хугацаа > Хоолойн диаметр (мм)/10 минут
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 Аpplication of PEX pipeline
- Technological
First generation: Peroxide crosslinking (PEXA)
Generation 2: Silane crosslinking (PEXB)
Electron Beam Irradiation Crosslinking (PEXC) Хоолой
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℃
Сelection 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

Our company qualification: At the same time holds WRAS, UL, W270 and other 12 international certifications
Solution of Pipe Installation
PVC хоолой:
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)
