Drop Weight Impact Testing Machine
DT Series drop weight impact testing machine are suitable for drop weight tear test to various kinds of ferrites, especially for the test of DWTT to pipeline steel as ASTM E436 and API 5L. Equipped with different weights and anvils, it can do other types of impact tests according to customers’ special request.
Adjusting impact energy by adjusting the lifting height and the numbers of the weights.
The buffer is equipped to absorb the residual energy after breaking the specimen to protect the weight and anvil from destroying. Also install the safe outfit, such as safety net, safe pin for maintenance and hanger locking.
Equipped with the specimen-carrying outfit, anti-falling of outfit for the specimen, centering outfit to guarantee quick, accurate and reliable tests.
