The use of flanged HDPE dredging pipes offers numerous advantages
in marine environments. These sturdy pipes are designed to easily
connect together, reducing the effects of wave-induced swings and
creating a smoother flow of media within the pipe.
These specialized pipes are specifically designed for drainage,
water-logging, dredging, and sand discharging in ports. Their
durability and flexibility make them an ideal choice for any marine
application. Additionally, their high-density polyethylene (HDPE)
construction provides exceptional resistance to corrosion,
abrasion, and chemicals, making them a reliable option for
long-term use.
With their easy connection and reliable performance, flanged HDPE
dredging pipes are a preferred choice for many port and marine
operations. They offer a cost-effective solution for managing water
and sediment control, keeping ports navigable and safe for ships
and vessels of all sizes.
The elongation at break percentage must be equal to or greater than 350%.
The longitudinal reversion at a temperature of 100℃ must be less than or equal to 3%.
The oxidation induction time at a temperature of 200℃ must be equal to or greater than 20 minutes.
The pipe must maintain its performance after being exposed to an aging energy greater than or equal to 3.5GJ/㎡. It must be able to withstand a static hydraulic strength of 80℃ for a duration of 165 hours without any breakage or leakage. Additionally, the percentage of breaking-elongation must be equal to or greater than 350%, and the oxidation induction time at a temperature of 200℃ must be equal to or greater than 10 minutes.
