ZwickRoell LP High-Energy Drop Weight Testers from 20,000 J

ZwickRoell DWT high-energy drop weight testers are used for testing and evaluating fracture surfaces of ferritic steels. The test method is described as a drop weight test in the following standards: API-RP 5L3, DIN EN 10274 and ASTM E436.Specimens from the pipe wall of large oil and gas pipelines are subjected to the drop weight test to API 5L. The specimens with a height equal to the original wall thickness and widths of several centimeters are subjected to abrupt loading via a vertically falling weight with a tup. The energy (weight and release height) is set so that the specimen breaks and the fracture surface can be assessed visually.
