Power Plant 2-Ply Testable Bellows For Steam Turbines

Most power plants have steam turbine cross-over expansion joints with 2-ply testable bellows. These redundant bellows are often overlooked during the piping system inspection.

A demonstration is provided with a recommended test fixture for safe and easy testing between the bellows plies. This is a video that is of interest to maintenance and turbine engineers, and inspectors.
