A Creep Testing Machine: second edition

The volume creep testing machine designed to test cylindrical rock salt specimen exposed by petroleum pressure in different pressures and desired temperatures. The volume creep testing machine comprises: two cells each of which included some parts such as the main cell, stabilizer system, insulator layer, heater, support layer, check valve and rubber sleeve. The main cells have the responsibility of retaining petroleum pressure and temperature and applying them to the specimen. A tank; to storage the fluid and transmit it with pressure into the cells through pipes. The tank consists of a hydraulic jack and six check valves as petroleum inlets and outlets. Ultrasonic testing systems; they used for measuring the thickness and strain of rock salt frequently. Each ultrasonic testing system comprises two dual element transducers and a memory to storage data. A thermometer and one pressure gauge which installed inside of the main cell.
