Hvilken type rør bruges til VVS?
Why is the selection of pipes a key decision for construction projects?
I design af bygningens vandforsyning og afløbssystem, “hvilken type rør bruges til VVS” is the core question that every engineer and purchaser must face. As an industry leader with more than 10 years of plumbing manufacturing experience, we have found that:
65% of pipe system failures result from poor material selection
30% of maintenance costs can be saved by optimizing pipe configuration
The new composite pipe market is growing at 12% annually
Here we will delve into the characteristics of 3 main pipes – PVC Pipes,Cooper Pipes & PEX Pipes and share industry-leading selection solutions.

Depth comparison of 5 mainstream pipes (with performance parameters)
1. PVC Rør – The king of cost performance
Material characteristics: PVC + stabilisator
Pressure range: 0.6-1.6MPa
Temperaturtolerance: -5℃ to 60℃
Advantage scenario:
Cold water supply system
Drainage/sewer lines
Chemical liquids delivery
Shopping tip: Check ASTM D1784 standard, pay attention to the wall thickness and pressure level match
Our advantages: The use of German KraussMaffei production line, wall thickness tolerance control within ±0.1mm, through NSF/ANSI 61 certificering.
2. Kobber Pipe – High-end durable choice
Levetid: mere end 50 år (according to the American Copper Development Association)
Antibacterial properties: natural antibacterial rate >99.9%
Installationspunkter:
Requires professional welding technology
Phosphorus-deoxidized copper pipe (C12200) is recommended
Cost analysis: Material cost is 40% higher than PEX, but maintenance cost is 60% lower
3. PEX Rør – New trend of flexible installation
Revolutionary breakthrough:
Temperaturområde: -70℃ to 110℃
Memory rebound features reduce joint use
Three types for comparison:
| type | Pressure resistance | Bøjningsradius | Applicable scenario |
| PEX-A | Best | 6D | Underfloor heating system |
| PEX-B | Medium | 8D | Regular water supply |
| PEX-C | Lower | 10D | Low pressure irrigation |
Our innovation: The development of PEX-AL-PEX composite pipe, bursting pressure up to 8.5MPa, suitable for high-rise buildings.

Selection & Decision
Recommended scheme according to the application scenario:
Residential water supply: PPR+PEX combination solution
Main pipe: DN25 PPR pipe (high temperature resistant)
Branch pipe: DN16 PEX pipe (flexible mounting)
Commercial building: kobberrør + stainless steel composite system
Water supply system: C12200 copper pipe
Fire system: 304 stainless steel pipe
Industriel pipe system: customized according to the characteristics of the medium
Chemical transmission: PVC-U+ fiberglass reinforced
High temperature steam: Seamless steel pipe + ceramic coating
