Rubber Air Hose VS PVC Air Hose Which is That You Really Need
Pneumatics are used in many of today’s industrial and automation environments, and there is an increasingly wide range of options from which to choose your components. Knowing how to choose pneumatic fittings is therefore all about suiting the materials to the job and its environment. In order to break down this process, you first need to identify:
1.Working environment
The design of pneumatic fittings should allow the free flow of required air or gas without any opportunity for significant drops in pressure. Pipes and hoses should be configured as simply as possible, so that no energy is lost in the air’s passage through the system. Always use straight runs wherever possible, and only use elbows and Ts if absolutely necessary.
2.Air pressure or PSI spec
Pneumatic fittings are frequently rated for certain operational pressure ranges, based on the specifications of the equipment and what it is designed to do. This pressure range (in PSI, or pounds per square inch) is the one at which a pneumatic system will generally be running at its optimum level of performance. If the correct operating pressure is not maintained, it could cause the whole system to fail, and components are likely to leak, break or lose their pressurised seal.
3. Approvals
In some application use cases, you may need to install a fitting which conforms to an industry or safety standard. The British Compressed Air Society (BCAS), for example, has a best practice guideline offering useful guidance on compressed air equipment for the food and beverage industry, including its selection, installation and maintenance. In these environments, the requirements for air purity are very strict, and may not allow for the use of compressors using oil-based lubricants. Bacteria and microorganisms are also a source of major concern.
4. Fitting material
When deciding how to choose the correct pneumatic fittings for your application, you should examine the different materials that are commonly used in order to determine their different physical properties, gas compatibility, and reaction to, for example, temperature changes.
5.Thread type
Thread size is always measured and formulated on the interior diameter of the conduit and corresponds to a specific number of threads per inch (TPI). The conduit size is measured in metric (mm) or imperial (inches), and proper sizing is critical, as over- or under-sized fittings will either be wholly incompatible or make an inadequate connection or seal.
