PIT-E DWTT Series Drop Weight Tear Testing Machine

This type of machine is used for the DWTT test on the ferrite steel, pipeline steel and other metallic materials. DWTT impact energy is measured under dynamic loading, to judge impact-resistance performance of the specimen, and to observe the specimen fracture surface in their temperature transition region from non-ductility to ductility. It is widely used in research and development of high specification thick pipeline steel and ferrite steel.

Specifications

  1. Maximum Energy: 20000, 30000, 40000 & 100000 J
  2. Angle of striking 81.6°, 106.3°, 135° adjustable
  3. High angle resolution of 0.025°
  4. Velocity of striking 5.788, 7.088, 8.183, 5.07– 8.96m/s
  5. Anvil span 254mm, radius of curvature 14.3mm
  6. Distance between support axis & percussion centre 2000mm and 2400mm
  7. Heavy duty seat and frame ensures stiffness and accuracy,reducing shock after impact
  8. High strength pendulum body ensures stiffness in axia and transverse direction
  9. Three types of pendulum raising device provides three types of impact energy without changing pendulum
  10. Automatic control: specimen feeding, impacting, pendulum raising and specimen collecting are fully automatically operated
  11. Uses servo motor as the power to raise pendulum with constant torque output and precise raising.
  12. Equipped with specimen feeding and positioning device provides rapid feeding, precise positioning, highefficiency and safety, and reducing labor intensity
  13. Equipped with pneumatic braking device avoids clutch
  14. working at high speed, reduces clutch impact abrasion, and extend its life
  15. Equipped with multiple energy display device showing test results at the same time
  16. Equipped with specimen collecting device, bring the tested specimen out of the machine. It allows operator to collect specimen without going inside, greatly improving efficiency and working safety
  17. Full-closed safety shield prevents splitting of teste specimen. Limit switch on the door ensures operator’s safety
  18. Power supply: AC440V, 3 50Hz & Weight: 40000kg

Applications

  • DWTT test on the ferrite steel, pipeline steel and other metallic materials
