Vilken typ av rör används för VVS?

Why is the selection of pipes a key decision for construction projects?

Vid utformningen av byggnadens vattenförsörjning och avloppssystem, “vilken typ av rör som används för 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-rör,Cooper Pipes & PEX Pipes and share industry-leading selection solutions.

Depth comparison of 5 mainstream pipes (with performance parameters)

1. PVC Rör – The king of cost performance

Material characteristics: PVC + stabilizer

Pressure range: 0.6-1.6MPa

Temperature tolerance: -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 certifiering.

2. Copper Pipe – High-end durable choice

Livslängd: mer än 50 år (according to the American Copper Development Association)

Antibacterial properties: natural antibacterial rate >99.9%

Installation points:

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 Rör – New trend of flexible installation

Revolutionary breakthrough:

Temperaturområde: -70℃ to 110℃

Memory rebound features reduce joint use

Three types for comparison: 

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: kopparrör + stainless steel composite system

Water supply system: C12200 copper pipe

Fire system: 304 stainless steel pipe

Industriell pipe system: customized according to the characteristics of the medium

Chemical transmission: PVC-U+ fiberglass reinforced

High temperature steam: Seamless steel pipe + ceramic coating
