DWTT-20000J~100000J Drop Weight Tear Impact Testing Machine Of Ferritic Steels
1. Instroduction
The testing machine is mainly used for drop weight tear test of pipeline and in thick steel ferritic steel, namely DWTT test. The test machine intergrating mechanical, electrical, automatic control technology to one, and to achieve fully automated process of feeding, lifting hammer, impact, fracture specimen collection, grab the hammer. In addition, this test machine has multi-channel protection measures, greatly improve the safety of operating personnel and equipment use. It is commonly used test equipment by the pipeline manufacturer, large steel mills, Iron and Steel Institute and other enterprises and research institutes.
