Creep testing is an essential technique for determining how materials change shape under long-term exposure to high levels of stress and temperature. This deformation can become so extreme that a component can no longer function properly – for instance, creep within a jet engine could cause the blades to contact the engine casing, resulting in dangerous and costly damage.
Creep testing is used by researchers and engineers to evaluate the durability of a wide range of materials and products, including power generation turbines, ovens, boilers, and pressure vessels. In a creep test, the material is subjected to a constant load at a constant temperature for a period of time, and its deformation is measured and recorded at specified intervals. The device then maps the strain over time to create a curve that demonstrates the rate of creep for the material.
The QualiCreep Series of Creep Testers specializes in measuring the performance of metals and alloys in high-pressure environments. Featuring high-precision lever weights that supply constant force, our devices provide 0.5 class accuracy that meets and exceeds ISO, ASTM, BS, SAE, and other international standards. The QualiCreep Series is also highly automated, which minimizes the need for human intervention and avoids the complications with manual adjustments seen in older models. Its PLC control system uses preset test programs to smoothly apply load to the test material and automatically provide heating, insulation, and cooling. In addition, a single computer can control multiple Creep Testers through a group control system.
Qualitest Creep Testers come in two models (the QualiCreep-30 and QualiCreep-50) that offer a diverse range of testing parameters and applications. Each device features an accessible touch-screen interface that displays temperature, allows users to set parameters, and enables online operation.
