What A Hard-Working Quality Inspection Team
Now the hose on the market can be roughly divided into plastic hose, silicone hose, metal hose, and stainless steel hose. Different material hose has the advantages and the scope of application are not the same, we as long as according to the actual use needs of the enterprise to choose the right hose material can! So take the high temperature resistant duct hose, its material is divided into many kinds, but also very many kinds. So the selection of it is need according to the temperature, pressure, medium, diameter, bending requirements, vibration and distortion of these aspects of reasonable purchase, so how to buy? Let’s get to know it together.
What problems should be paid attention to in selection of high temperature resistant duct hose?
1. Temperature: Refers to the conveying medium temperature and working environment temperature. Sometimes there will be a short time of high temperature also need to consider, clearly tell the sales staff general working temperature and high temperature.
Because under normal circumstances, the higher temperature resistance, the unit price is relatively high.
2. Pressure: Divided into positive pressure and negative pressure, positive pressure is higher than normal pressure (that is, often said to be an atmosphere) of the gas pressure of the gas state. For example, when you pump air into a bicycle or car tire, positive pressure is produced at the outlet end of the pump or pump. The outlet of the fan reaches the air supply outlet, which belongs to the positive pressure section. “Negative pressure” is the pressure of a gas below the normal pressure, which is often said to be one atmosphere. The use of negative pressure is very common, people often make a certain part of the space appears negative pressure state, can use the ubiquitous atmospheric pressure for our effectiveness. For example, when you breathe, when your lungs are expanding there’s negative pressure, there’s a pressure difference between the inside and the outside of your lungs and fresh air is forced into your lungs. The fan inlet reaches the air inlet, which belongs to the negative pressure section.
3. The medium and whether there is corrosion: Refers to the material and its properties transported by the high temperature hose, different media will directly determine the material of the high temperature hose. Especially corrosive media, inform the sales staff of the specific chemical composition, because the high temperature hose of chemical resistance to choose more materials, only know the specific ingredients, in order to choose cost-effective products.
4. Inside diameter: We generally say the inside diameter of the hose, because the hose is generally connected with the customer’s hard pipe. High temperature resistant hose with inner diameter from 40mm to 900mm can be produced.
5. Bending requirements: Application and installation parts of the pipeline direction and bending degree, different high temperature hose small bending radius is not the same.
6. Vibration and distortion: The use of parts of the vibration, movement and distortion.
The above is to introduce the six factors that need to be considered when choosing high temperature resistant duct hoses. I hope to help you after reading them! After all, high temperature hose is different from other hose to choose and buy. It has many materials and types. So in order to avoid choosing the wrong material and model of high temperature hose, we must strictly follow the above requirements to choose and buy high temperature resistant duct hose, so as to ensure the application effect of high temperature resistance!
