Abstract

This invention relates to the field of testing equipment technology, specifically to a stainless steel corrosion performance testing equipment for a full-zone simulated seawater environment. The equipment includes: a test chamber, which is vertically arranged along the interior of the chamber via multiple partitions, sequentially from top to bottom, comprising an atmospheric test zone, a splash test zone, a tidal range test zone, a full immersion test zone, and a sea mud test zone; and a simulation unit, including a sea breeze simulation component and a wave simulation component respectively connected and installed on the side wall of the test chamber, for providing a simulated seawater environment. By separately setting the atmospheric test zone, splash test zone, tidal range test zone, full immersion test zone, and sea mud test zone inside the test chamber, the equipment can work with the sea breeze simulation component and the wave simulation component to simulate a full-zone seawater environment. This allows for convenient testing of the corrosion resistance of stainless steel pipes in different zones of a simulated real marine environment, improving the accuracy of the test, reducing the manpower and material resources consumed in the test, and reducing the workload of the personnel involved in the test.
