Spiral plate heat exchanger shell
Feb 03, 2021

The shell of the spiral plate heat exchanger is a connection structure that bears internal pressure or external pressure. In order to improve the pressure bearing capacity of the shell, the shell of the spiral plate heat exchanger is welded by a combination of two semi-cylindrical bodies. The key part of this combination welding is the connecting plate. The connecting plate is connected to the spiral plate and the shell by placing the connecting plate on the spiral body, welding on both sides, and then welding the two semicircular shells with the connecting plate. The welding structure adopts the butt weld with the liner to make the butt welding Seam guarantees welding quality.
