Vacuum injection hose

When choosing a suitable vacuum injection hose, it is first necessary to clarify the required tubing and performance indicators. Then, you can choose according to the following aspects:

1. Material selection: vacuum injection hose is made of a variety of materials, common silicone, fluorine rubber, polytetrafluoroethylene (PTFE), and polyvinyl chloride (PVC) and so on. Silicone has the characteristics of high temperature resistance, corrosion resistance and abrasion resistance, which is suitable for high temperature environment and chemical contact; Viton can maintain the elasticity at very low temperature, which is suitable for low temperature environment; PTFE has good corrosion resistance, which is suitable for some special environments, such as acid and alkali corrosive occasions. According to the specific needs to choose the right material.

2. Size selection: the size of the vacuum injection tube is usually expressed in terms of inner diameter, outer diameter and wall thickness. The inner diameter determines the flow of fluid in the pipe, while the outer diameter and wall thickness affect the pressure-bearing capacity and durability of the pipe. Select the appropriate size according to the needs of specific application scenarios.

3. Pressure-resistant selection: vacuum injection hose needs to have a certain pressure-resistant ability to ensure that no bursting and leakage will occur during operation. Pressure resistance mainly depends on the material and structure of the tube, you can check the relevant parameters provided by the manufacturer to select the appropriate vacuum injection tube.

4. Selection of corrosion resistance: If the application scenario requires the vacuum injection tube to be in contact with corrosive substances such as acids and alkalis, it is necessary to select a tube with good corrosion resistance, such as silicone or PTFE and other materials. In general, the use of ordinary PVC pipe can meet the demand.

5. Temperature range selection: vacuum injection tube in the work will be affected by the temperature, so you need to choose the appropriate pipe according to the temperature range of the specific application scenarios. For example, silicone tubing can withstand high temperatures, suitable for medium temperature environment; and Viton tubing for low-temperature environments, can maintain good elasticity.

6. Softness selection: softness refers to the degree of softness of the pipe itself, soft pipe in the construction process is easier to operate and bend, applicable to the need for frequent changes in the construction direction of the occasion. Selection of moderate softness of the pipe can better meet the actual needs.

7. Wear-resistant choice: If the application scenario requires vacuum injection tube often friction with hard objects, then you need to choose a good wear-resistant tubing, so as not to use the process of wear and tear too quickly lead to leakage or leakage. Silicone tubing is often chosen because of its good abrasion resistance.

8. Price and availability of choice: Finally, according to the price and availability of tubing to choose. The price of vacuum injection tubing will vary from material to material, and factors such as the supplier's reputation and delivery lead time should also be considered.

In conclusion, choosing the right vacuum injection hose requires comprehensive consideration of material, size, pressure resistance, corrosion resistance, temperature range, flexibility, abrasion resistance, price and availability. Through careful comparison and selection, you can find the vacuum injection hose that best suits your needs.
