Pneumatic hoses conduct gases at high pressure and are used in power tools, hydraulic systems, and aviation. They are made of plastics or reinforced with fiber or metal. Pneumatic tubing is resistant to damage and is lightweight and flexible. The system includes pumps, valves, and cylinders to ensure safety and reliability. There are no strict import or export restrictions on pneumatic tubing, but it can be expensive and must be replaced if damaged.
Pneumatic is a term referring to air, gases or wind movement, but a pneumatic hose in industry is understood as a hose capable of conducting gases at a pressure higher than atmospheric pressure. In mechanics, pneumatics is the application of pressurized gases to do work. Many power tools, such as nail guns, pneumatic wrenches, and drills, use pneumatic pressure. Some hydraulic systems also work on the principle of pneumatics, such as the air brakes on some planes and trains.
Tubing designed for pneumatic applications, as well as pneumatic valves and accessories, are often made from plastics, such as nylon, rubber, or polyvinyl chloride (PVC). The high pressure pneumatic hose can also be made of plastic, but reinforced with fiber sheath or metal fabric to strengthen the design. This is often referred to as braided pneumatic hose. High-pressure pneumatic hose used in aviation systems and elsewhere must meet government safety and testing guidelines to avoid potential explosion, loss of control of an aircraft, or engine failure itself.
In addition to being able to withstand high gas pressures, pneumatic tubing in general is also resistant to damage from a wide variety of common industrial chemicals, temperature changes, and natural oxidation. Manufacturers of pneumatic hoses sell it internationally for many purposes, for agricultural, construction and household uses, so it must be made to withstand a variety of conditions. It’s also built to be lightweight and flexible so it’s easy to work with and easy to connect to fittings.
The combined use of pneumatic pumps, solenoid valves and pneumatic cylinders ensures that all parts of a system are able to withstand the increase in pressure. A common example of this is a compressed air system used for power tools. The system has a compressor motor that draws in outside air, sends it to a pneumatic cylinder that stores it under pressure, and releases it via an electrically or pneumatically controlled valve through the pneumatic hose that feeds the tool. The entire system is based on parts, hoses and fittings designed with similar pressure ratings to ensure safety and reliability.
There are high quality pneumatic tube manufacturers from China to USA. Due to its widespread and daily use, there are no strict import or export restrictions on it. Despite its common availability, however, pneumatic tubing can be expensive. Once damaged, it usually cannot be repaired and must be replaced with a new hose.
