Electro-hydraulic servo universal testing machine

　　Electro-hydraulic servo universal testing machine: metal specimen tensile, compression, bending and shear test. Drop-testing machine: used in composite materials, metal materials, auto parts, such as the impact of the performance test sample, can get the change process of the material and the structure when impact, and thus plays a guiding role on the material formula and structure design. Testing machine for ISO180/ASTM D256/ASTM D6110/ASTM D3763/ASTM D1709 standard.

　　Testing machine control system can realize 32-bit full digital control, the control system adopted the most advanced digital signal processor technology, can undertake a variety of computing including total energy, the maximum load, impact velocity, test time, etc.

　　Impact testing machine: impact testing machine is divided into manual pendulum impact testing machine, semi-automatic impact tester, non-metallic impact testing machine, etc. It is a kind of new type of impact testing machine instantaneous measurement and recording materials in the process of impact characteristic curve. By changing the pendulum and sample base, it can realize two forms of test including simply supported beam and cantilever beam. By measuring angular displacement signal, it transferred to the computer for data processing with high precision.

　　Online ultrasonic: longitudinal and weld defects detection, stratification of the heat affected zone and the inside burr height control, mainly for the production process control.

　　For fast production speed, defect tracking spraying device, to guarantee 100% detection, tracking, and resection of weld and inside burr defects. Online squash: according to the raw material and production characteristics, sampling do weld and stress direction of 0 degrees and 90 degrees of flattening test, safeguard the basic properties of the welded pipe requirements.

　　Hydrostatic test: for each base metal and weld of the pipe to provide safeguard.

　　Offline weld ultrasonic testing: used for longitudinal and steel pipe weld defects inspection after water pressure test.

　　Measure and the weld for layered detection. Pipe end and groove surface ultrasonic testing: testing tube parent metal and weld material delamination, crack and horizontal defect.
