The types of stainless steel hydraulic joints are introduced in detail. The pipe joint is a detachable connecting piece between the oil pipe and the oil pipe, the oil pipe and the hydraulic system. It should be satisfactory for easy assembly and disassembly, firm connection, firm sealing, small size and large oil-passing ability. , The working pressure damage is small, and the production and processing technology performance is good. According to the connection method between the oil pipe and the pipe joint, the pipe joints mainly include welding type, ferrule type, flaring type, and snap-on type. Bevel, tee and other types; the connection methods with the human body include external thread connection, flange connection and other methods.


In addition to this, there are also some pipe joints that are satisfactory for special purposes. Types of hydraulic pipe joints Pipe joints are detachable connecting parts between oil pipes and oil pipes, oil pipes and hydraulic systems. It should be satisfactory for easy assembly and disassembly, firm connection, firm sealing, small size, large oil-passing capacity, and working pressure. Small damage, good production and processing technology performance, etc. According to the connection method between the oil pipe and the pipe joint, the pipe joints mainly include welding type, ferrule type, flaring type, and snap-on type. Bevel, tee and other types; the connection methods with the human body include external thread connection, flange connection and other methods. In addition to this, there are also some pipe joints that are satisfactory for special purposes.








1. Welded pipe joints Welded direct pipe joints are mainly composed of a connecting head body 4, a nut 2 and an acceptor 1, and an O-ring 3 is used to seal the middle of the connecting head body and the acceptor. When the connector body is screwed into the human body, a metal sealing ring or a combined gasket 5 is used to seal the inner hole. It is accepted that the seamless steel pipe in the pipeline management system is connected by electric welding. Welded pipe joints are firmly connected and sealed. The disadvantage is that electric welding is required during installation. Therefore, thick-walled seamless pipes must be selected, and electric welding requires a lot of labor.


2. The structure of the ferrule type pipe joint. This type of pipe joint mainly includes a connecting head body 4 with a 24° conical hole, a sleeve-type joint 2 with a sharp inner edge, and a clamping nut 3 for the actual effect of clamping. When the nut 3 is tightened, the ferrule type joint 2 is promoted to a 24° taper hole, and with the deformation, the ferrule type joint and the spherical surface of the connecting head body form a curved surface contact seal; in addition, the inner knife edge of the ferrule type joint is placed On the surface of the oil inlet pipe l, an annular concave groove is pressed out on the outer inner wall, which has a solid sealing effect. The ferrule type pipe joint has the advantages of simple structure, excellent function, light quality, small size, convenient application, no need for electric welding and welding, and the specification of the shaft diameter of the seamless steel pipe is not tight. The ideal pipe joint in the management system.


3. Cone-sealed welded pipe joint Ningbo City Pipe Joint Manufacturer Pipe Joint Distributor Cone-sealed welded pipe joint structure. This type of pipe joint is mainly composed of the connecting head body 2, the nut 4 and the receiving 5. In addition to the advantages of the welded pipe joint, because its o-ring is installed on the 24° cone of the receiving 5, the sealing has a good effect. Maybe after conditioning, the seal will be firmer. The pressure is 34.5 CPa, and the operating temperature is -25°C to 80°C. There are more and more applications of such pipe joints.
