Product Details
Socket weld couplet is similar to socket weld boss except that a straight length of weld ring is furnished. The one side is socket welding connection, and the other side features a beveled transition to a straight length of welding ring.

ASME B16.11 socket welding couplet is a welded branch plate that is welded to the main pipe and connected to the branch pipe, either by welding or threaded connection. It is considered the most popular in the group, and is often classified as a butt-welding connection (BW butt-welding). This classification refers to the beveled outlet that is welded during installation to the branch pipe. It is highly suitable for replacing tees with reinforced connections on 90-degree branch pipes, as this connection protects the branch pipe by reducing stress concentrations caused by the shape and size of the branch pipe. The beveled end allows for easy installation on previously cut main pipes and branch pipes through butt-welding, with the internal or nominal diameter of the branch pipe usually being less than or equal to the diameter of the welded branch plate. The main application is commonly found in hot well and instrument connections.
