Proper Labeling of Piping Systems Increases Safety

Industrial facilities can have a multitude of piping and utilities within them. Some of the piping can all look similar, especially if it is not labeled. water, sprinkler lines, compressed air, even steam, and refrigeration lines are just a few of those that can easily be seen within a number of manufacturing facilities. Proper labeling of these helps to ensure plant safety and can also lead to higher efficiencies within the system.

Properly labeled compressed air piping.

So how does labeling lead to safety? Well, in more than one occurrence I have been inside of facilities where piping that was not intended for compressed air, such as PVC was used for it. When the incorrect piping gets used it can become easily confused and if the contractor that is installing new equipment doesn’t do their homework then it can lead to catastrophic errors. For instance, piping can rupture, or even worse, you could easily pipe the incorrect utility into a piece of equipment. Imagine seeing PVC pipe, which is used for water, and hooking it to a rinse application only to find someone improperly used the piping for industrial compressed air. Or vise versa, an unlabeled pipe thought to be compressed air is actually city water and the next thing happening is water raining down on a packaging blowoff.

This all can and should be easily prevented by properly labeling any and all piping systems thoroughly throughout the facility. This not only names the utility but generally shows the flow direction as well which an help determine where the source is coming from as well. When performing the first step in the 6 Steps To Compressed Air Optimization knowing the direction of flow is critical when installing a Digital Flowmeter in order to assess system efficiency for compressed air.

The proper labeling and utilizing proper piping within industrial environments can easily prevent accidents and ensure ease of troubleshooting or new installations because the piping is already labeled. If you would like to discuss more on what types of piping are acceptable to use with compressed air, feel free to contact an Application Engineer.

Want to Know How Much Money you can Save? Use EXAIR’s Efficiency Lab

Growing up as a kid of the 80’s I remember wanting a Nintendo 64. This was very much a want due to the excellent advertising and having friends that got them when they first came out. So, like many kids of the times, I set forth to present my case to my parents and sell them on the benefits to me receiving this 64 bit wonder of the world. These benefits all revolved around me doing chores and “helping” to earn money to go towards the end goal. Thinking back now, I really should have started to learn more about negotiating earlier in life because my parents and older brother really made out on the deal. The point is, I had to make sure that they saw a return on their investment. Mainly, I would be entertained and they would get some stuff done around the house without complaints.

Optimizing Your Compressed Air System in 6 Steps!

If you’re a follower of the EXAIR Blog, you’re probably well aware that compressed air is the most expensive utility in an industrial environment. The average cost to generate 1000 Standard Cubic Feet of compressed air is $0.25. If you’re familiar with how much air you use on a daily basis, you’ll understand just how quickly that adds up. To make matters worse, many compressed air systems waste significant amounts of compressed air just through leaks. According to the Compressed Air Challenge, a typical plant that has not been well maintained will likely have a leak rate of approximately 30%!! Good luck explaining to your finance department that you’re carelessly wasting 30% of the most expensive utility. To make sure you get the most out of your compressed air system, it’s important to follow the Six Steps to Optimizing Your Compressed Air System.

Starting with Step 1: Measure the air consumption to find sources that use a lot of compressed air. In order to have an understanding of your compressed air usage across various processes and in your entire facility, you have to measure and produce a baseline. Without a measurement of usage, there’s no way to determine your actual costs or evaluate opportunities for savings. To do so, EXAIR offers a range of Digital Flowmeters from stock. The Digital Flowmeter provides a digital readout of the exact amount of compressed air being used. Many companies will install the DFM on each major leg of their air distribution system to allow for constant monitoring and provide a benchmark of compressed air usage.

Once you’ve measured your baseline, it’s time to explore another simple avenue of savings. Step 2 in the process is finding and fixing leaks in your current system. EXAIR offers our Model 9061 Ultrasonic Leak Detector to allow you to locate and fix any leaks within your distribution system. With an unmaintained system wasting on average 30% of the produced volume, this one seems like a no-brainer but is often overlooked. If you can hear the leak without the help of a device like the ULD, it’s a VERY bad leak. These should be located, tagged, and repaired ASAP!

After getting a baseline measurement of the air consumption in your facility of compressed air usage and locating and fixing leaks in your system, it’s time to begin implementing some changes. Step 3 of the 6 Steps to Optimizing Your Compressed Air System covers upgrading your blowoff, cooling, and drying operations using engineered compressed air products. EXAIR manufactures a variety of products that can help to ensure you’re using your compressed air in the best way possible. While it may seem simple, easy, and cheap to use something like an open-ended pipe or tube for blowoff, the fact of the matter is that the volume of air that these homemade solutions use quickly make them more expensive. Look no further than EXAIR when seeking a safe, efficient, and reliable engineered blowoff solution.

EXAIR Intelligent Compressed Air Products such as (left to right) the Air Wipe, Super Air Knife, Super Air Nozzle, and Air Amplifier are engineered to entrain enormous amounts of air from the surrounding environment.

Step 4 may be the easiest of any of the others. TURN IT OFF! You can’t waste compressed air when it’s turned off. By strategically placing valves at various points throughout the distribution system, it allows you to isolate areas of the facility that may not require continuous compressed air usage. It isn’t exactly feasible to eliminate every single leak, so even if you’ve closely followed Step 3 it’s still beneficial to close some valves here and there to further reduce your consumption. In some applications, such as products traveling on a conveyor, it may be possible to utilize a product like EXAIR’s Electronic Flow Controller to ensure air isn’t wasted in between parts on the conveyor.

The 5th step in the 6 steps to optimizing your compressed air system highlights the use of intermediate storage of compressed air near the point of use. Receiver tanks are installed in the distribution system to provide a source of compressed air close to the point of use, rather than relying on the output of the compressor. Compressed air receiver tanks are an integral part to many compressed air distribution systems. Compressed air is stored at a high pressure after drying and filtration, but just upstream of point of use devices. The receiver tank is charged to a pressure higher than what is needed by the system, creating a favorable pressure differential to release compressed air when needed.

Think of a compressed air receiver tank as a “battery”. It stores the compressed air energy within a system to be used in periods of peak demand, helping to maintain a stable compressed air pressure. This improves the overall performance of the compressed air system and helps to prevent pressure drop. They should be placed strategically to provide a source of compressed air to intermittent high-volume applications.

The last step, Step 6, discusses the use of pressure regulators at the point of use. Pressure regulators are available to control the air pressure within the system and throttle the appropriate supply of air to any pneumatic device. As the last of the six steps to optimizing your compressed air system, controlling air pressure so that you’re only consuming as much as necessary can have a dramatic impact. EXAIR sells a variety of systems that will include a suitably sized pressure regulator to ensure you’re operating as efficiently as possible.

Follow these 6 steps and make sure you get the most out of your compressed air system!

Compressed Air Leaks and the Problems They Cause

Over the Fourth of July I had a great opportunity to do some backpacking in the backwoods of the Adirondack Mountains in Upstate New York. “That sounds awesome!” is what most people would think; looking back on it, it was awesome. BUT, at the time it was the very definition of complete and total suffer fest. During my time on the trail, I learned three life lessons. First, always thoroughly study up on every bail out point along the trail. Second, water proofing has its limits; and thirdly, when things leak it is dreadful. After 7 miles of crawling over rocks and traversing lakes and streams in the pouring down rain everything was soaked and water was leaking through our rain jackets, leaving me and my girlfriend cold, wet, and sore as all get out – all on day one.

Leaks don’t just stink when they appear in your rain coat, they are dreadful all around whether it is leaking faucets, a leaky basement or compressed air line leaks. Unlike the fact that I currently have no solution for the leaking rain coat, I do have a solution for your leaking air lines. Leaks are costly and an all-around waste of money that can have severe implications on how the air is being used and the entire system itself.

There are four main affects that a leak in your compressed air system can have and they are as follows; 1) leaks can cause a pressure drop across the system, 2) leaks shorten the life of almost all air supply system equipment, 3) leaks demand increased running time of the compressor, and 4) leaks produce unnecessary compressor capacity by demanding more and more air.

  • A pressure drop across your compressed air system can lead to a decreased efficiency of the end use equipment (i.e. an EXAIR Air Knife or Air Nozzle). This adversely effects production as it may take longer to blow off or cool a product or not blow off the product well enough to meet quality standards.
  • Leaks can shorten the life of almost all supply system components such as air compressors. This is because the compressor has to continuously run to make up for the air lost from leaks. By forcing the equipment to continuously run or cycle more frequently means that the moving parts in the compressor will wear down faster.
  • An increased run time due to leaks can also lead to more maintenance on supply equipment for the same reasons as to why the life of the compressor is shortened. The increase stress on the compressor and supply side components due to unnecessary running of the compressor.
  • Leaks can also lead to adding unnecessary compressor size. The wasted air that is being expelled from the leak is an additional demand in your system. If leaks are not fixed it may require a larger compressor to make up for the loss of air in your system.
EXAIR’s Ultrasonic Leak Detector

It is fairly easy to find these leaks, simply use EXAIR’s affordable Ultrasonic Leak Detector. This leak detector uses ultrasonic waves to detect where costly leaks can be found so that they can be patched or fixed. So don’t get stuck in some rainy day with your compressed air leaking everywhere; find those pesky leaks, mark them for maintenance and seal them up.
