The application of hydraulic pipes in lifting and lifting in the industrial and other fields is very common, which has saved a lot of burden for people’s work. What problems should you pay attention to during the use of hydraulic pipe fittings? The sleeve type pipe joints must be strictly in accordance with the standards…
What is a hydraulic pipe The hydraulic pipe is called a hydraulic pipe because it is a pipe for transmitting hydraulic pressure. It has a hard pipe and a hose. The hard pipe is mainly a seamless steel pipe, and the hose is used. The steel mesh of the layer and the rubber are bent…
The rubber tube of the cloth is composed of an inner rubber layer, a multi-layer cloth woven or a cord winding layer and an outer rubber layer. Causes of uneven thickness of the rubber layer of the rubber tube 1. When the mandrel is used, the air volume is not properly controlled, and the tube…
1. The rubber tube is stored in a relaxed state as much as possible. Generally, the hose with an inner diameter of 76 mm or less can be stored in a coil. 2. During the storage of the rubber tube, it is strictly forbidden to stack heavy objects on the pipe body and prevent external…
Under heating conditions, the raw rubber in the rubber compound reacts with the sulfide, and the crosslinking process of the macromolecule of the rubber from a linear structure to a three-dimensional network is called vulcanization. The vulcanized rubber is called cooked rubber. After vulcanization, the physical, mechanical properties and other properties of the rubber compound…
1. Molecular structure of rubber: Rubber is also a polymer compound with a relative molecular mass of several hundred thousand. The molecular size of the polymer compound is not fixed, and the so-called relative molecular mass refers to its average relative molecular mass. The relative molecular mass has a great influence on the rubber strength.…
