Polyurethane ducting hose is a flexible and abrasion resistant hose. PU duct hose can transfer abrasives like sand, gravel and particle. Thus it is ideal for material handling like wood work.
How to tighten the PU steel wire hose is a problem often in the hose industry. Because you have to avoid leakage during the process of transferring materials. Besides, fix it tightly can avoid positive and negative pressure. Therefore, there are several connection methods for PU ducting. While those include thread, flange and clamp. These 3 methods are the most popular. But which one is better for you? In fact, you need to choose the proper one based on your special work.
First, if you use a PU duct hose pipe to transfer granular or powdery, use the hose clamp. Because it is easy to install and uninstall. Besides, clamp is the cheap choice. Thus it can save much cost. However, it has bad seal performance. Thus if the medium is fluid or air, there may be leakage problem. Thus it is only ideal for particle and powder.
While if you use large diameter hose to transfer powder, gas and liquid media, flange is the best choice. The flange connection has great sea and can resist a certain pressure. Thus there will never be leakage problem. But it will be not that easy to install. Besides, the PU hose and the flange is a combination. Thus the cost of such method costs much.
In some cases, your PU flexible ducting may be short for a long distance use. Then you have to connect two hoses together. While a threaded connector is necessary. Because this method can connect two pipes with good seal. In addition, it is ideal for powder, gas and liquid.
In a word, each connection method has its own advantages. Thus you need to choose the proper one based on your special work. If you need polyurethane duct or have any questions, welcome to contact we Orientflex. We will offer you the best solution.
