1100°C High Temperature Hydraulic LCF Grips Series HTG

The HTG grips are the ideal choice for conducting high-temperature Low Cycle Fatigue (LCF) Tests in combination with high temperature furnace.

These grips with hydraulic specimen preload are specially designed for Low-Cycle Fatigue Testing or for any other reverse axial stress application up to 15 Hz or tension-only application.

The reverse rated grip extension with inside pushrod for specimen preloading and the exchangeable specimen adapters extend into the heated zone of the furnace. These pars are made of high-temperature super alloys with high
strengths at high temperature.

The grip body, which remains outside of the furnace, is water cooled and isolate the hot parts of the grips from the actuator piston rod and from the load cell or other accessories.
When hydraulic pressure is applied the grip piston moves and push the pushrod against the end of the specimen. The adjustable grips pressure defines the specimen preloading that can be set in relation to expected introduced compressive forces.

These grips can accommodate various sizes of threaded and button-end specimens. A view port in the grip extension helps to position the threaded specimen in the adapters.

All parts of the HTG grips are accurate machined with tight tolerances for improved and repeatable alignment.
