Pipe Connecting Structure of Expansion Joint for Preventing Stress Concentration

摘要

The present invention relates to the joint structure of the expansion joint for preventing stress concentration, and relates to the joint structure of the expansion joint to prevent the stress concentration phenomenon due to the fastening after the connection.;The structure of the present invention is a joint structure of the expansion joint is provided with a plate which is fastened by bolts along one circumference of the flange portion of the pipe, the plate is integrally formed in a circle along the circumferential surface of the flange portion to the bolt It is to prevent the stress concentration, characterized in that coupled by.;The present invention having such a configuration forms a plate with a single member forming a circle so that the force acting on the flange part is evenly distributed throughout the structure through the structure fitted to the flange part of the pipe, thereby creating a local stress concentration phenomenon on the flange part. It can be prevented. As a result, cracks are not generated due to stress concentration at the flange and the pipe connection, thereby improving reliability of the product and maintaining a firm joint state.
