DWTT-W Series Computer Control Drop Weight Tear Testing Mach


DWTT-W Series Computer Control Drop Weight Tear Testing Mach
1.Application:
DWTT-W Series Computer Control Drop Weight Tear Testing Machine is mainly used for Pipeline Steel and Medium Thick Steel Plate Ferritic Steel to drop weight tear test, that’s DWTT Test.
It can set machine, electric, pneumatic, automation technologies together, in order to implement the feed, fracture specimen collection in a fully automated process.
Besides, equipped with multi-channel protection measures,this tester can improve the operation of 
personnel and equipment used in security greatly.

2.Standards:
GB / T8363-2007 "Ferritic Steel Drop Weight Tear Test Method"
API RP * 5L3-96 American Petroleum Institute Proposed Approach;
ASTM E436-03 Ferritic Steel Drop Hammer Dynamic Tear Test Standard Method;
ASTM E604-83 Metal Material Dynamic Tearing Standard Methods.
