Manufacturers of hydraulic pipe joints introduce the types of sealing connections between hydraulic pipe joints and pipes. There are different forms of sealing connections between hydraulic pipe joints and pipes. The pressure grade series are also different. The main sealing structures are as follows:
The ferrule type pipe joint is to enter the 24-degree inner cone hole of the joint body through the action of external force under the condition that the ferrule has the condition (the joint body has a 24-degree inner cone hole). The ferrule is elastically deformed, and a rigid seal is formed on the outer diameter of the tube and the inner cone surface of 24 degrees.
The flared pipe joint is connected to the pipe through a union nut (A type with a ferrule) that has been welded to the pipe in advance. The connection nut presses the plane of the pipe onto the O-shaped rubber seal ring on the end face of the joint body to form elasticity seal.
Cone-face welded pipe joints are directly connected to the 24-degree conical joints welded to the pipe in advance by connecting nuts. The connecting nut presses the O-shaped rubber sealing ring placed on the conical joints against the cone of the 24-degree inner cone of the joint body. An elastic seal is formed on the face.
The main sealing structures of the above-mentioned hydraulic pipe joints will be explained in detail in the next class.
In a piping system, the pipe outer diameter series indicates related related parts. For other working conditions, other materials and non-standard parts, the allowable pressure should be agreed with the pipe joint manufacturer's hydraulic pipe manufacturer's working pressure specified by the standard. The strength and practicability of the joint and the safety factor of the connection seal must be guaranteed to be 4 times. Pipe joint manufacturers are obliged to verify the non-standard pipe joint pressure. The temperature load performance of steel hydraulic pipe joints. The allowable working temperature of steel hydraulic pipe joints is generally -20-120 degrees, and the ambient temperature is -40 degrees. Standard production of pipe joints does not need to specify the low temperature resistance at present. The production plant using hose connection and steel pipe connection at -40 degrees ambient temperature has not found any adverse effects in the current production practice.
