Portable Indentation Tester (PMT-1000) Product Introduction   

Product Overview  

The PMT-1000 Portable In-situ Micro-indentation Tester, jointly developed by Wuxi Zhanghua Pharmaceutical Equipment Co., Ltd. and Jova Glenn Technology Co., Ltd.,  is a non-destructive online testing device based on the indentation method/indentation energy difference method. It focuses on mechanical properties and residual stress testing for energy equipment (e.g., pressure vessels, pipelines), serving third-party testing institutions and frontline production units. It provides critical data support for finite element simulation, failure analysis, lifespan evaluation, and safety assessments.  


Core Functions  

1. Mechanical Property Testing  

   - Tensile properties (yield strength, tensile strength)  

   - Hardness, fracture toughness, strain hardening index  

   - Biaxial residual stress  

2. Residual Stress Testing  

   - Indentation energy difference method, indentation strain method, X-ray diffraction method (for comparative validation)  

3. Application Scenarios  

   - Pressure vessels, long-distance pipelines, remanufactured energy equipment  

   - Welded joints, thick-walled cylinder weld seams, heat exchanger tube plates, etc.
