Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does the SDR value affect the pressure rating of HDPE pressure pipes?

The SDR (Standard Dimension Ratio) defines the relationship between the pipe’s outside diameter and wall thickness. A lower SDR indicates a thicker wall, which enhances the pipe’s ability to withstand higher internal pressures. This means pipes with lower SDR values are better suited for high-pressure applications, while higher SDR values are appropriate for lower-pressure systems.

What impact does temperature variation have on the performance of HDPE Pressure Pipes?

HDPE pipes exhibit good performance across a wide temperature range. However, at higher temperatures (above 60°C), the material may soften, reducing its pressure resistance. In colder environments, HDPE remains flexible and resilient but may become brittle below freezing. Temperature-based de-rating ensures the pipes pflegen structural integrity at various operational temperatures.

How does the chemical resistance of HDPE Pressure Pipes affect their usage in industrial applications?

HDPE pipes provide excellent chemical resistance, making them suitable for transporting aggressive chemicals and acids. The material resists corrosion, oxidation, and degradation by most chemicals. For high-risk environments, HDPE can be engineered to resist specific chemicals by modifying its composition, ensuring long-term reliability even in harsh industrial conditions.

What are the effects of soil movement on HDPE Pressure Pipes during installation?

HDPE pipes are inherently flexible, allowing them to absorb and adapt to soil movement, reducing the risk of cracks or breaks. This makes HDPE ideal for areas with seismic activity or shifting soils, as it can withstand ground settlements, thermal expansion, and contraction without compromising the pipe’s structural integrity or pressure resistance.

How do HDPE Pressure Pipes perform in systems that experience surge pressure?

HDPE pipes handle surge pressures better than rigid materials due to their flexibility und high elongation properties. These pipes can absorb transient pressure spikes, preventing damage or failure in systems like water or gas pipelines where rapid pressure changes can occur. Their ability to withstand surge pressure helps pflegen system reliability and reduces the risk of catastrophic failures.
