Have the PVC Braided Hoses been Maintained Correctly?
How to choose pneumatic hose?
The basic function of pneumatic hoses is to deliver compressed air to actuators, valves and other equipment tools. But there are countless types and sizes of pneumatic hoses on the market, so engineers need to consider many factors when choosing pneumatic hoses.
From the beginning of production, in order to increase strength, hoses for air applications and pneumatic hoses can be extruded from a single material or internally reinforced (usually using textile fibers). Pneumatic hoses usually consist of an inner rubber layer, one or more layers of reinforced braided or spirally wound fibers, and an outer rubber layer. Broadly speaking, pneumatic hoses are stronger than hoses, but they are more expensive.
The application of pneumatic hoses has strict size requirements. Choosing a smaller inner diameter will “clog” the flow and cause pressure loss, inefficiency and excessive fluid velocity, thereby shortening the service life. On the other hand, a diameter that is too large will result in higher weight, size and cost than required. Therefore, it is necessary to select the appropriate size and wall thickness according to the scene and machinery used.
Also make sure that the pneumatic hose can be used normally under the specified maximum working pressure. Manufacturers usually rate hoses by their bursting pressure and then divide them by an appropriate safety factor (usually 3:1 or 4:1) to determine the maximum working pressure. Please keep in mind that the published burst pressure ratings are for manufacturing testing purposes only and do not in any way mean that the product can safely handle pressure peaks or otherwise operate above the maximum working pressure.
Two common physical characteristics to consider when selecting pneumatic hoses are flexibility and kink resistance. These attributes are usually subjective, and it is best to use the actual product for testing rather than relying on text descriptions. In addition, there are many types of colors, various colors and transparent, mainly depending on the color of the compound.
