Description
Product Description
Product Features
1. A 12mm manganese steel alloy plate with a support framework is used as the external pressure-bearing material, and the pressure-bearing capacity can reach 10T per square meter.

2. A replaceable stainless steel flange interface with fast sealing technology is equipped with aviation terminals to achieve a vacuum leak-free test of the test specimen under load.

3. Advanced low-pressure constant temperature technology is adopted to ensure that the temperature remains constant with minimal fluctuations under any temperature conditions in a low-pressure state.
