With the accelerated evolution of modern industry towards high temperature, high pressure, and extreme environments, the performance of materials and structures during long-term service directly determines the reliability and service life of critical equipment such as aircraft engines, nuclear energy systems, petrochemical devices, and new energy batteries.
In these harsh operating conditions, creep and fatigue often occur simultaneously and are coupled — equipment start-up and shutdown generate alternating loads, while high-pressure operation causes creep damage. Together, they impose stringent requirements on material performance that exceed conventional testing standards.
How to accurately reproduce the internal gas pressure environment that components experience during service, and systematically evaluate their creep and fatigue behavior under controlled conditions? This is the core issue that the HOFUTECH Gas Internal Pressure Creep-Fatigue Testing Machine is dedicated to solving.
In the field of gas internal pressure creep-fatigue testing, HOFUTECH maintains a clear strategic positioning:
