Product Details

DWTT-10000 Pipeline Steel drop hammer impact test machine

Product Description

1. Application:

The drop hammer impact test machine is mainly used for drop weight tear test of

pipeline and middle, 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.
