BMT-E/BH – ELECTROMECHANICAL PIPE RING STIFFNESS TEST MACHINE
BESMAK® BMT-BH Electro-Mechanical Pipe Stiffness Testing Machines are specialized systems for evaluating the compressive strength and stiffness of pipes and culvert sections. These machines apply load steadily (without impact) along the length of pipe specimens or other pre-formed parts, to determine their deformation under load and ultimate crushing strength. The electromechanical drive system provides smooth, precise loading and is ideal for long-duration load tests. BMT-BH machines accommodate pipe specimens with diameters from 200 mm up to 4000 mm, covering a wide range of standard pipe sizes made of materials such as concrete, steel-fiber-reinforced concrete, PVC, and composite materials. This system meets international standards for pipe stiffness and compression tests while ensuring accurate results and operator safety.
Standards:
- N/A
- Controlled by the BESMAK Sematron closed-loop electronic controller for precise load application and measurement.
- Capable of applying loads up to 300 kN for pipe compression tests.
- Ultra-high displacement measurement resolution of 0.1 μm for detecting minute deformations.
- Wide range of displacement control speeds (from 0.0001 mm/min to 500 mm/min) to simulate various loading conditions.
- Integrated BESMAK universal testing software for full computer control, data acquisition, and analysis.
- Ergonomic working height and easy-to-use controls for operator comfort, even with large specimens.
- Remote control unit with live display, soft keys, and Specimen Protect function for safe and convenient operation.
- High-precision load measurement via Class 0.5 load cell for accurate force readings.
- Interchangeable load cells available to optimize accuracy for different expected load ranges.
- 24-bit data acquisition ensures extremely detailed force and deformation data collection.

Note. The testing frame is delivered disassembled and has to mounted on site following the instructions. The customer can also manufacture locally the testing frame, and purchase the loading/control system only. Testing frames with different capacity and features can be manufactured as per customer’s requirements. Quoted testing frame cannot be sold in the CE markets.
