There are many types of pneumatic hoses, generally made of PU raw materials, with stable quality, wear resistance, high pressure resistance, smooth and flexible pipe body, high elasticity, and small bending radius. PU pneumatic hose is also divided into:
1. PU (polyester-polyurethane) pneumatic tube
2. PU (polyether-polyurethane) pneumatic tube
Polyester-polyurethane pneumatic tubes are generally of the air-passing type, and if they are used for passing water, their service life will be affected.
Polyether-polyurethane pneumatic tubes can pass both air and water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic tubes.
Pneumatic hoses can be used for powder spraying, powder coating, compressed air, or as cooling water pipes, etc., and are used in a wider range of industries.
Strong toughness, small bending radius, high bendability.
High wear resistance, crush resistance, high tensile strength and tear strength.
Good oil resistance, gasoline resistance and chemical resistance.
The inner and outer walls are smooth, the friction coefficient is low, and the medium passing capacity is high.
Color can be customized on demand, easy to identify pipelines.
The polyurethane pneumatic hose is suitable for compressed air, common industrial water and non-corrosive oil.
In order to maintain a long service life, it must be used under the rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly, if the limit is exceeded, the hose may burst.
The fluid temperature is too high or the fluid has corrosive chemical costs, which may cause the hose to rupture. The working environment temperature is too high or there is chemical gas in the working space, which may cause the hose to crack. Storage in a humid place or storage period expires If it is too long, it will hydrolyze or age the hose, which may cause breakage.
