Description

Externally Pressurized Expansion Joints is located in expansion joints group. Multi-node expansion joints are used in order to dampen expansion amounts in pipeline lines with longer line lengths. Thus, as the number of knuckles increases, the possibility of twisting of expansion joint also increases. Layner prevents this situation to a certain extent. However, the most efficient method is the use of Externally Pressurized Expansion Joints
