The HP Storm Pipe is an advanced drainage solution made from polypropylene, engineered for optimal performance in stormwater management, combining durability, chemical resistance, and superior joint integrity for reliable use.
What is a HP Storm Pipe ?
HP Storm is a high-performance polypropylene pipe designed for drainage applications involving gravity flow. HP Storm is the ideal option when pipe stiffness and superior joint performance are needed. Dual-wall profile design and advanced polypropylene resin technology contribute to exceptional performance and durability.
Why Is Polypropylene Pipe Ideal for Storm Drainage Projects
This type of HP pipe is frequently the preferred option for distributing stormwater through a gravity flow process because it is designed with a dual wall and the most recent polypropylene resin technology, which meets or surpasses national standards in terms of a wide range of applications and exceptional dependability.
Features and Benefits
- Increased stiffness results in an additional safety factor against construction loading and poor installations.
- The extended bell and spigot joint meets ASTM D3212 and ensures lab and field testable watertight performance.
- Smooth interior with a Manning’s value of 0.012, resulting in increased flow capacity.
- Inert PP material is resistant to the effects of chemicals, abrasion, hot soils, and effluent.
- Lightweight product for best installed cost to maximize delivery and installation efficiencies.
- Readily available in convenient locations to service local projects.
Advantages Associated with HP Pipe
- Large-scale plumbing project specialists like you might want to think about utilizing HP storm pipe instead of other available piping options for a few reasons, including:
- These dual-walled storm drainage pipes feature a corrugated exterior structural wall and a smooth interior wall
- The Manning’s value of the high-performance polypropylene pipe is 0.012, which is particularly smooth, which enhances the already superior flow capacity these pipes can handle
- When compared to your typical plastic pipe options, these storm drainage pipes are an estimated 100% stiffer, which means it offers a longer service life (100 years) compared to inferior drainage piping options
- PP pipes are stiffer than plastic pipe options, meaning they’re sturdier and likely to last longer — especially as far as joint integrity is concerned
- The durability of this HP storm drainage pipe has built-in protection should installations or loading go awry during the construction process
- These PP pipes are considered lightweight, thus resulting in an easier construction loading and installation process and less costly delivery than other drainage piping options
- Polypropylene pipes like these are an ideal substitution when one might otherwise use concrete pipes for their rigidity, such as in the case of a culvert, especially where the integrity of the surrounding soil could affect
- the service life of the selected storm pipe per this NC State University report
- The polypropylene material HP storm drainage pipe is made from can withstand consistent contact with abrasive materials, such as chemical substances, and fluctuations in temperatures.
Differences between an HP pipe and an HDPE pipe
HP and HDPE pipes are popular choices for high-performance stormwater management, offering distinct advantages and limitations. Understanding their structural integrity, resistance to environmental stressors, long-term maintenance requirements, and installation concerns helps stakeholders make informed decisions for optimizing their stormwater drainage systems.
Material composition
Polypropylene is lighter, with superior heat resistance and chemical resistance properties, whereas HDPE is denser, stronger, and has better impact resistance and low-temperature flexibility.
| Aspect | Polypropylene (PP) | HDPE |
| Weight | Lighter | Heavier |
| Durability | Moderate | High |
| Rigidity | Higher | Lower |
| Shock Resist. | Lower | Higher |
| Temp Tolerance | Higher (160°C) | Lower (130-137°C ) |
| Sunlight Resist. | Needs additives | Better |
| Chemical Resist. | Strong | Strong |
| Clarity | Translucent | Opaque |
| Uses | Packaging, textiles | Pipes, containers |
Durability and corrosion resistance comparison
HDPE and polypropylene pipes have varying performance in different environments. HDPE pipes are ideal for harsh environments like mining and wastewater systems due to their non-polar molecular structure, making them resistant to acids, organic solvents, and bases. Polypropylene pipes, on the other hand, show superior endurance to non-polar diffusive solvents but less strength to alkaline substances and inorganic salt solutions. Both materials have superior tensile strength, but the choice depends on specific chemical, temperature ranges, and mechanical load.
Performance in high-pressure applications
High-pressure tasks require materials with tensile strength, resistance to break, and cooling elongation load. Polypropylene, with a tensile strength of 25-38 MPa, is prone to deformation. PTFE or high-grade polymers can withstand structural deformations. Tensile strength must exceed the application’s limit, temperature resilience must be maintained, and corrosion resistance must prevent negative reactions. The best material is chosen based on safety and efficacy.
Conclusion
HP Storm Pipe stands out as a superior choice for stormwater management due to its advanced polypropylene construction, exceptional durability, and chemical resistance. Its dual-wall design and high stiffness ensure reliable performance under various conditions, making it ideal for gravity flow applications. With government approvals and proven effectiveness, the HP Storm Pipe is a trustworthy solution for engineers and contractors seeking long-lasting drainage systems in diverse environments.
