drop weight impact test machine

drop weight impact test machine

1.Usage and Characteristics

 It is used for drop weight tear test for ferrite steel (especially all kinds of pipeline steel). This machine is composed of frame part, feeding part, hammer part, anvil part, safety protection part and control system.

It adjusts the impact energy through adjustment of weight thallium quantity and impact height, the energy range is stepless from zero to full speed.

 Different size hammer and anvil can be customized to meet other types of impact test. Different energy test system is available to meet different test demand.

 Test standard: GB/T 6803-2008 <Test Method for Drop-Weight Test to Determine Nil-Ductility Transition Temperature of Ferritic Steels>
