1. Introduction of hydraulic pipe joints

Hydraulic pipe joint is a connecting part, it is a connecting joint between high-pressure oil pipe and high-pressure oil pipe. It has many classifications, which can be divided into welded pipe joints, high-pressure hoses, transition pipe joints, high-pressure ball valves, etc.

Second, the principle of hydraulic pipe joints

Different types of joints have different principles. Here, I will introduce the related principles of welded pipe joints. Welded pipe joints, as the name suggests, are obtained by welding, and a circular seal is used 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, the requirements for welding quality are very high, and it is inconvenient to install and disassemble.

3. Cleaning of hydraulic pipe joints

The cleaning of hydraulic pipe joints is divided into two types: kerosene cleaning and pickling. Kerosene cleaning is mainly for copper pipes and stainless steel pipes. First, remove the pipes and joints to be cleaned, use a cloth with kerosene to clean the interior and observe the view, and then put Both ends and joints can be directly soaked in kerosene for cleaning. The standard after cleaning is that there should be no visible contamination. Pickling is mainly aimed at heavily corroded steel pipes. First, degrease, wash with water, then remove rust, and then neutralize with lye. Be careful not to wash away the marks on the pipes.
