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
- Mechanical Property Testing
- Tensile properties (yield strength, tensile strength)
- Hardness, fracture toughness, strain hardening index
- Biaxial residual stress
- Residual Stress Testing
- Indentation energy difference method, indentation strain method, X-ray diffraction method (for comparative validation)
- Application Scenarios
- Pressure vessels, long-distance pipelines, remanufactured energy equipment
- Welded joints, thick-walled cylinder weld seams, heat exchanger tube plates, etc.
