How to choose a suitable pneumatic hose
Medium features
The medium characteristics of high-pressure cylinder connecting hoses used in different industries are different. For example, the media in the petroleum and chemical industries are often corrosive, flammable and explosive. The media in the medical and food industries are relatively safe. Therefore, when choosing the material of the connecting hose, consider the medium features first. Ensure that the material has corrosion, fire and explosion resistance.
Working pressure and temperature
The high pressure cylinder connecting hose needs to withstand a certain working pressure and temperature. Connecting hoses of different materials have different strengths and temp resistance. Thus you should choose a material with sufficient strength and good temp resistance.
Economic efficiency
On the premise of meeting the medium characteristics and working pressure and temperature requirements, the economic efficiency of the connecting hose material is also an important consideration. The cost of connecting hoses of different materials varies greatly. It is necessary to select materials with higher cost performance according to actual needs and budget. Among these materials, metal hose and PTFE hose are more expensive. While plastic hose and rubber hose are relatively cheap.
Safety
In most cases, the gases inside the cylinder are flammable, toxic or corrosive. Thus when you choose a flexible hose, the safety is the most important factor. The hose should have excellent air tightness. Besides, it should has excellent abrasion resistance. In welding or cutting industry, there will be open fire, thus the hose should also be flame retardant.
