Many people have never understood hydraulic pipe joints, let alone what they do. Based on the retrieval of relevant materials, I now share the principles and removal methods of hydraulic pipe joints with everyone, and I look forward to helping everyone.
One, Detailed introduction of hydraulic pipe joints
The hydraulic pipe joint is a connection component. The bite-type pipe joint wholesale is a connection joint between the hydraulic oil pipe and the hydraulic oil pipe. Electric ball valve, etc.
Second, the principle of hydraulic pipe joints
Different types of joints have different principles. Here I will introduce the principles related to welded pipe joints. To put it bluntly, welded pipe joints are obtained by electric welding. The joints and butt joints are sealed with a ring. The structure of this pipe joint is very simple, the manufacturing cost is not high, it is relatively easy to manufacture, and the airtightness is good. It's just that the welding quality standard of electric welding is very high, and it is inconvenient to install and disassemble.
Third, the removal of hydraulic pipe joints
The cleaning of hydraulic pipe joints is divided into kerosene cleaning and pickling passivation. Kerosene cleaning is mainly for air-conditioning copper pipes and stainless steel pipes. The rotary pipe joints are customized. The pipes and joints to be cleaned are first removed, and the cloth is dipped in kerosene. Clean the viewing platform on the inside, and then immediately soak the sides and joints in kerosene for cleaning. The specification after cleaning is not possible to estimate the contaminants that can be seen from this. The key to pickling passivation is seamless steel pipes with serious rust. First, de-oil them, wash them with water, then rust-proof, and then combine them with caustic soda solution. Be careful not to wash the markings of the pipes.
