Description
The 3117-501 pullrods reverse-stress pullrods with hydraulic preload designed for elevated temperature Low Cycle Fatigue applications. The pullrods are also suitable for hot tensile tests and other reverse axial stress applications.
Application Range
- Full reverse stress high temperature testing
- High temperature fatigue testing
- High temperature tensile testing
- High temperature fracture mechanics (when used with optional high temperature CT grips)
Features and Benefits
- Designed with an external rod diameter of 60mm to provide lateral stiffness for excellent alignment characteristics
- Provides proven repeatable alignment to Class 5 according to ISO12106 & ASTM E606 when used in conjunction with AlignPro alignment fixture 1
- Suitable for threaded or button headed specimens with the appropriate specimen adaptors
- Features replaceable specimen insert seats to enable easy refurbishment
- Lower pullrod includes integrated angular adjustment capability
- Interchangeable adapters allow various threaded-end and buttton specimen sizes to be accommodated
- Preloading mechanism is hydraulically driven - more repeatable than manually clamping
- “One touch operation” via the use of an electric pump (3117-503 only) thereby eliminating variations due to human error
- Scribed feature on pullrods to enable consistent rotational allignment
- Precision faces are all water cooled to allow tighter tolerances without the risk of seizing due to high temperatures
- No rotation of specimen or any components during clamping
