The high pressure pneumatic hose is a flexible, current-insulating material that is resistant to UV rays and other external factors. The purpose is to supply air streams from the compressor to the tool. They are used to equip spray guns, grinders, screwdrivers, etc. Pneumatic high-pressure hoses are used in various industries, widespread due to their practicality and excellent operational properties.
Areas of use
The specificity of the application depends on the characteristics of the tubes and the material from which it is made. Polyamide is widely used in the motor and automotive industry, the design of welding machines, technical devices for laboratories, and measuring instruments. They are indispensable in centralized lubrication and hydraulic systems.
Polyurethane models are more resistant to mechanical and dynamic stress. They are used in industries with high loads. In particular, motors and machines are equipped with polyurethane hoses; they are used to create connections in measuring and control technologies.
Polyethylene are the most common, characterized by a universal purpose. They are most often used to complete pneumatic tools: industrial and household.
Differences in material
The flexible structure of the pneumatic hose is due to the use of special elastic raw materials. According to the type of material, products differ in:
- polyvinyl chloride. Made from PVC. Such models are characterized by excellent flexibility, high elasticity, resistance to twisting, kinking, UV;
- polyamide. The main properties of such tubes are light weight, flexibility, resistance to high pressure, a wide range of operating temperatures;
- polyurethane. They are characterized by the following indicators: high elasticity, resistance to damage, abrasion. Retain the flexibility of the structure at low temperatures;
- teflon. Such tubes belong to the category of heat-resistant materials, resistant to aggressive media, UV, ozone;
- rubber with a reinforced frame. These pneumatic hoses have a special reinforced casing that gives the product extra strength.
Depending on the type of tubes and the type of material from which they are made, the scope and design properties differ.
Nuances of choice
First of all, you should pay attention to the type of pneumatic hose and its technical characteristics. In particular, the material affects the operating temperature range. So, polyurethane air hoses are able to maintain functionality at -40 - +60 degrees. The working pressure indicator is responsible for the operation of the product at a certain degree of compression of the medium.
Exceeding the recommended parameter may cause damage to the tube. On average, the allowable pressure is no more than 15 atm.
Another technical feature includes the hose design. They are straight and spiral. The latter are more compact, save effective space, and are more convenient to work with. It is worth paying attention to the diameters: external and internal. This figure determines the throughput of the tube. The recommended permissible inner diameter for efficient operation of the air tool is> 5 mm. Length is another important characteristic of hoses. They range from 5 to 20 m. However, you should not choose too long pipes, as this will reduce the productivity of the compressed medium supply. Correctly dimensioned length reduces pressure loss.
Differences and another aspect that should be clarified when choosing are the type of connection of hoses with pneumatic tools: bayonet and rapid. The second is also known as quick-disconnect messages. They are more convenient to use, they are modern in comparison with the bayonet mount.
In general, when choosing a pneumatic hose, you should be guided by the technical characteristics and recommendations of the manufacturer. In view of this, it is necessary to purchase such products in specialized stores or on websites.
