In industrial settings, securing PU flexible ducting hoses properly is a common challenge. The goal is to prevent leaks during medium conveyance and ensure stable pressure in gas delivery. To address this, there are several connection methods for duct hoses, including threaded, flange, and clamp connections. All three methods work, but which is best? The choice ultimately depends on the medium and working conditions.
Here are some tips from Orientflex to help you select the right hose connection method:
1. Hose Clamp Connections
Ideal for granular or powdery media, hose clamps are a practical choice. They are easy to install and uninstall, saving both time and costs. This makes them convenient for applications like transferring grains or powders. However, they have a drawback: poor sealing for liquids or gases. Using a hose clamp for water or gas transfer can lead to leakage, so avoid this method in those cases.
2. Flange Connections
For general powder, gas, or liquid media, flange connections are reliable. Their tight seal minimizes the risk of leaks, making them suitable for applications where airtight or watertight connections are crucial. However, flanges come with higher costs than clamps. Additionally, once installed, they are not easily removable, which can limit flexibility in reconfiguring the hose system.
3. Spiral Connections
When connecting one PU duct hose to another, spiral connections are effective. They provide both sealing and pressure resistance, accommodating powders, gases, liquids, and other media. Like flanges, though, spiral connections come with a higher price tag, which may be a consideration for budget-sensitive projects.
Final Notes
All three methods are widely used for PU duct hose connections. But the key is to match the method to your specific medium. For example, use clamps for dry powders, flanges for sealed systems, and spirals for hose-to-hose joins.
