Product Description

High-pressure RJ face-to-face welding flange is a common way to connect pipes, which has the characteristics of simple structure and good sealing.

First of all, the length of the high-pressure RJ face-to-face welding flange is usually a standard size, such as DN50, DN100, etc., to adapt to different pipe diameters. Its length design is reasonable, which can ensure the connection firmness and sealing in the welding process.

Secondly, the welding length of the high-pressure RJ face-to-weld flange is usually 1.5 times the standard requirement, which can ensure the welding strength and sealing. During the welding process, the weld joint should be prepared, such as cleaning, chamfering, etc., to ensure the welding quality. Then, through the welding process, the flange and the pipe are connected, and the inspection is carried out after welding to ensure that the quality of the welding meets the standard requirements.

Finally, the connection length of the high-pressure RJ face-to-face welding flange needs to be adjusted according to the actual situation. In practical applications, appropriate adjustments can be made according to the requirements of the pipeline's working pressure and medium to ensure the safety and reliability of the connection.

All in all, the length of the high-pressure RJ face-to-weld flange is usually the standard size, and the welding length is 1.5 times the standard requirement, and it can be adjusted according to the actual situation. This connection method has the characteristics of simple structure and good sealing performance, and is widely used in various pipeline connections.
