As can be seen from the table data, the key advantages of SCH 10 pipes are reflected in three dimensions:
1. Lightweight and economical:
Thin-walled structures (e.g., DN25 pipe: 2.77mm thick, weighing 2.09kg/m) reduce transportation and installation costs by more than 30%. The weight reduction effect is even more significant for large-diameter pipes (DN600 only 94.53kg/m).
2. Scientific wall thickness gradient:
The wall thickness increases in a stepped manner with increasing pipe diameter (DN250→4.19mm / DN350→6.35mm / DN750→7.92mm), maintaining a stable structure while withstanding design pressure (typically ≤2.5MPa), simplifying the selection process.
3. Precise operating condition adaptation:
Based on optimized pressure parameters, it is particularly suitable for:
HVAC systems (chilled water/HVAC)
Low-pressure fire protection piping networks
Atmospheric pressure chemical media transportation
Steam systems with operating pressure ≤1.6MPa (requires STPT material)
Meets the compliance requirements for non-corrosive fluid pipelines in the food/pharmaceutical industries.
