Guide to Compressed Air by Using HDPE Pipes

In our daily life, air compression systems are used in many places, including home workshops, body workshops and manufacturing plants. The parts that connect all the components together in the compressed air system are HDPE pipes.

Of course, regardless of the application, it is important that air compressors work properly when you need them. The pipeline in the system can determine the profitability of the enterprise. Next, I'll show you a guide to using HDPE pipes to compress air.

Introduction of compressed Air Piping system

The basics of compressed air piping are simple. All you need to do is pipe the compressor to the end-use equipment. But no matter how simple it looks in the manual, you'll find it a little complicated when you try to apply it to your office. Many compressed air terminals require isolation and ventilation. Because many of your devices require external walls, you will find that you need to travel long distances to deliver compressed air to all end devices. This can be a challenge unless your property is doughnut shape. One of the main disadvantages of getting all compressed air from one source is that you end up sacrificing the simplicity of the plumbing system. Planning compressed air piping systems is the last consideration when organizing the workshop. The environmental conditions and requirements of plant equipment often exceed the planned simplification of supply lines.

How to select a HDPE pipe

High density polyethylene is unique in that its molecular structure has very little branching, making it more intermolecular force and tensile strength than other forms of polyethylene. The density of HDPE pipe can range from 0.93 to 0.97g / cm 3. However, the strength difference is greater than the density difference, giving HDPE pipe a high specific strength. HDPE pipe is also harder, more opaque, and can withstand higher temperatures than other forms of polyethylene (248 °F for short periods, 230 °F continuously). They don't corrode, so you don't have to worry about rust falling into the air. This in turn reduces the risk of congestion. And the inner surface is smooth and never spoiled, promoting laminar flow; pipes are light in weight and easy to transport and install; cutting HDPE pipes is fast and simple and requires basic tools; HDPE pipes can be glued together, which is cheaper and faster than welding metal.

Matters need attention

When designing compressed air piping systems, you may think you should focus on connectors. After all, this is the most likely place to leak. Most people think leakage is the biggest threat to the efficiency of the system. However, this is not necessarily the case. There are three factors that have a greater impact on pressure efficiency than leaks:

1. Acute-angle

The sharp angle in the pipe system hinders the flow velocity and reduces the pressure. The air cannot think or turn, so a bent redirection in the piping system ejects it from the inside of the pipe. Soon there will be an undirected route that wastes energy. This type of airflow is called laminar flow. The swirling flow path is known as turbulence. 90 degree bends usually cause turbulence up to 3 to 5 PSID of pressure loss. As a result, eliminate sharp bends and install a series of 30-to 45-degree bends.

2. Moisture

Water corrodes certain types of pipes, causing rust and peeling into the air. This rust and steam will reach end-use equipment, plug nozzles and pollute the materials you intend to deliver or apply compressed air. In addition to clogging and pollution problems, corrosion of rusty pipes produces rough surfaces. This is the second reason for turbulence, so moisture has a minor effect on reducing air pressure.A solution to reduce moisture in compressed air piping systems is simple: replace the supply source from which air is drawn. The water produced by compression is heavier than compressed air, causing it to fall to the bottom of the compressor. Inhaling air from the top of the compressor will reduce moisture.

3. Disorder and blockage

A solution to reduce moisture in compressed air piping systems is simple: replace the supply source from which air is drawn. The water produced by compression is heavier than compressed air, causing it to fall to the bottom of the compressor. Inhaling air from the top of the compressor will reduce moisture. The inevitable particulate content in the inlet of the compressor requires an air filter. As with dryers, it is best to install an effective air filter before the compressor to remove any particles that may be circulating in the pipe and to block inline equipment, valves and end-use nozzles.
