Quality operation of the pneumatic system is based on completely eliminating the possibility of air leakage. Solving this problem is quite simple, as manufacturers have developed a huge number of different devices. But best of all, a pneumatic fitting copes with the task, which is presented in the form of a part for tight and reliable fastening.
Description
Pneumatic fittings are commonly referred to as products that work in constant contact with compressed air. Such units allow you to ensure optimal functionality of the entire system. Devices guarantee the tightness of the channels, due to which they are used as an element for complex assemblies in the transitions of air channels. All modern pneumatic fittings can be used at high temperatures. They can withstand quite a strong external impact, while remaining unharmed.
Advantages and disadvantages
Traditional pneumatic fittings are usedspecialists for the installation of detachable connections based on thread or crimp pressure. Provided that the units are correctly installed, the units provide reliable sealing of the system. The choice of a specific product depends on the required reliability. Key benefits include:
- Pneumatic fittings are universal, they can be used for plumbing installations.
- Products are made from high-quality alloys and polymers that are resistant to aggressive environments.
- Parts are perfect for connecting pipes with a diameter of 9 mm.
- High degree of sealing, even if the system has been repeatedly dismantled.
The only drawback of the products is the high cost, as well as the limited use of collet connections.
Material used
Quick release pneumatic fitting can be made of rilsan, nylon, polyethylene, polyurethane, teflon. Many manufacturers actively use nickel-plated steel, stainless alloys and even copper. It should be noted that brass pneumatic fittings are suitable only for those operating conditions where there is no exposure to an aggressive environment. Experts identify several key categories of connectors that can help prevent air leakage:
- Simple connectors.
- Angled and straight.
- Adapters.
- Splitters, tees.
Selection rules
To purchase quality fittings for pneumatic tubes, you needfollow certain rules carefully. Particular care should be taken in cases where the products will be used to assemble medical units, systems and instruments. The fixture should correspond as much as possible to the material and characteristics of the equipment. Strict requirements are set for chemical industries, as well as for those systems that operate under high pressure, risk of water hammer and extreme temperatures. When choosing pneumatic fittings, be sure to pay attention to the following parameters:
- Internal environment. Peak and operating pressure in the system.
- Place of operation of the connection. It can be a room, a street. It is necessary to take into account not only climatic features, but also the degree of space heating.
- Manufacturer's recommendations as well as international criteria.
- Fixation type (collapsible, stationary).
In addition, the optimal configuration or purpose of the connecting node must be taken into account. Some units are designed for residential use, but there are more advanced products that will cope with all industrial operating conditions.
