First, the identification method
The specifications and models of rubber hoses are generally composed of inner diameter, pipe wall thickness, length and material. Specific markings are typically printed or labeled on the hose wall. There are three common marking methods: printing, labeling, and hot pressing. Among them, the printing mark method is the most widely used method.
2. Check the precautions
When looking at the specifications and models of rubber hoses, the following aspects should be noted:
1. Inner diameter size: The inner diameter is one of the key dimensions of the hose. The appropriate inner diameter size should be selected according to the specific use requirements and the size of the connecting pipe fittings.
2. Material: According to the use environment and media, the material of the rubber hose is not the same. The appropriate material should be selected according to the actual situation.
3. Pipe wall thickness: The greater the pipe wall thickness, the greater the strength and pressure resistance of the hose. However, an excessively thick pipe wall will increase the weight and cost of the hose, and should be treated as a compromise according to the actual situation.
4. Length: The length should be selected according to the specific use occasion. It is necessary to consider the connection mode and distance between the hose and the pipe and the equipment, and determine the length reasonably.
3. Selection of rubber hose specifications and models
The selection of rubber hose specifications and models needs to be determined according to the actual use environment and requirements. In general, the following aspects need to be considered:
1. Type of medium: The material and hardness of the hose should be selected according to the type and nature of the medium.
2. Working pressure: When choosing, the appropriate pipe wall thickness should be selected according to the actual working pressure.
3. Temperature range: The temperature resistance range of rubber hose is also a very important index. It should be selected according to the actual operating temperature.
4. Connection: Choose the appropriate specification and model according to the connection between the hose and the connecting pipe fittings.
