BMT-BH – SERVO-HYDRAULIC PIPE RING STIFFNESS TEST MACHINE
BESMAK® BMT-BH Servo-Hydraulic Pipe Stiffness Testing Machines are built for high-capacity loading of large-diameter pipe specimens. Using a servo-hydraulic actuation system, these machines can apply the very high forces necessary to test the stiffness and load-bearing capacity of concrete and composite pipes, including those used in infrastructure and drainage systems. The robust 4-column frame and closed-loop control ensure smooth and accurate load application over long durations, which is crucial for standard pipe crushing and creep tests. Like the electromechanical version, the servo-hydraulic BMT-BH machines accommodate pipe diameters from 200 mm up to 4000 mm, enabling comprehensive testing across a wide range of pipe sizes with reliable, repeatable results.
Standards:
- N/A
- Axial load capacity up to approximately 1000 kN (customizable to specific testing requirements).
- Special electromagnetic displacement sensor for highly accurate piston travel measurement during loading.
- Adjustable crosshead design to handle various specimen sizes and lengths.
- Ergonomic working height and user-friendly controls to improve operator efficiency and safety.
- Long-stroke, high-speed hydraulic actuator ideal for repetitive loading of pipes with similar dimensions.
- Anti-rotation guidance prevents any torsional movement of the actuator during the compression of the pipe.
- Hydraulic system configuration and machine performance can be tailored to the application (e.g., faster loading rates or higher capacity, as needed).
