The hydraulic hose is a connecting element, which is the connecting joint between the high-pressure oil pipe and the high-pressure oil pipe. There are many types of it, which can be divided into welded pipe joints, high-pressure hoses, transition pipe joints, high-pressure ball valves, etc. The principles of different types of joints are different. Here, I will introduce the relevant principles of welded pipe joints. As the name suggests, welded pipe joints are obtained by welding, with a circular seal between the joint and the nozzle. The structure of the pipe joint is relatively simple, the production cost is not high, the production is relatively easy, and the sealing performance is good. However, it has high requirements for welding quality, and it is inconvenient to install and disassemble. The cleaning of hydraulic pipe joints is divided into kerosene cleaning and pickling. Kerosene cleaning is mainly for copper and stainless steel pipes. First remove the pipes and joints to be cleaned, wipe the interior with a cloth dipped in kerosene for observation, and then directly soak the two ends and joints in kerosene for cleaning. The standard after cleaning is that there should be no visible contamination. Pickling is mainly aimed at severely corroded steel pipes. First degrease, wash with water, then remove rust, and then neutralize with lye. Be careful not to wash off the traces from the pipes.
