1. Detailed introduction of hydraulic pipe joints
The hydraulic pipe joint is a connection component, which is a joint between the hydraulic oil pipe and the hydraulic oil pipe. It has many categories, which can be divided into welded pipe joints, high pressure hoses, multi-type pipe joints, electric ball valves, etc.
2. 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 joint and the butt 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 quality of electric welding is very high, and it is not convenient to install and disassemble.
3. he 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 pipes and joints to be cleaned are first removed, and the inside of the viewing platform is cleaned with a cloth dipped in kerosene. , And then immediately soak the sides and joints in kerosene and clean them.
The specification after cleaning is not an estimate of the air pollutants that can be seen from this. The key to pickling and passivation is seamless steel pipes with serious rust. First, deoil them, wash them with water, and then anti-rust treatment, and then combine them with caustic soda solution. Take care not to wash the markings of the pipes.
