Drop Weight Tear Testing (DWTT) Machine

DWTT Machine

The tester is mainly used for drop weight tear test of pipeline steel. The testing machine integrates mechanical, electrical and automatic control technology, and realizes the full automatic process of feeding, lifting hammer, impact, breaking sample collection and grasping hammer. In addition, the tester is equipped with multiple protective measures, which greatly improves the safety of operators and equipment. This machine is a commonly used testing instrument for pipeline steel manufacturers, large steel plants, iron and steel research institutes and other enterprises and scientific research institutions.
