The Creep Tester is a test equipment designed to evaluate creep fractures in materials by applying a specific tensile or compressive load at a constant temperature for an extended period of time, which demonstrates exceptionally excellent stability and durability, even during prolonged testing at high temperatures exceeding 1,000°C. After applying a specific tensile or compressive load to the specimen over a long period, the variation in its length is measured. When a fracture occurs during testing, the test is automatically terminated, after which the creep curve and relevant data are analyzed. Concurrently, the heating device (furnace chamber) is deactivated to ensure maximum safety.

• 

  A heating system stably controlled by PID even at high temperatures (1,000°C or higher)
  ( Error: ± 2℃)

• 

  A system with the maximum accuracy of load application through its automatic leveling controller

• 

  A safe system that automatically detects any fractures, overheating, and other abnormalities of the specimens, and immediately terminates the test, warning the user of such incidents.

• 

  A structure that allows a weight to be instantly and safely replaced.

The Small Punch Creep Tester is used to evaluate fracture toughness characteristics (transition temperature, elastic-plastic fracture toughness, etc.) of equipment by cutting out a small piece of specimen directly from the base material to the extent that the integrity of the subject equipment is maintained.

The small punch test has emerged as a pseudo-nondestructive method for evaluating material degradation because the equipment does not need to be demobilized to collect the specimen piece and remedial treatment is not required after sampling. The fracture toughness of the base metal degraded during operation can be directly obtained, and additional welding repairs are not required for the base metal after collecting the sample. It offers the advantages of not only facilitating the direct evaluation of the fracture toughness of the base material degraded during operation but also eliminating the need for additional welding repairs to the base material after sampling.

• 

  Evaluation possible with a tiny specimen (0.5 mm thick x 6.5 mm diameter) taken from the base material

  • No welding repairs required after specimen collection
• 

  Monitoring embrittlement and damage progression of structural members, with direct evaluation of tensile strength after long-term service.

• 

  Excellent reproducibility of test results
