JL Drop Weight Tear Testing (DWTT) Machine

DWTT Machine

This testing machine is mainly used for drop hammer tear testing of pipeline steel and medium thick steel plate ferrite steel. This testing machine integrates mechanical, electrical, and automatic control technology, achieving a fully automated process of feeding, lifting the hammer, impact, collecting fractured samples, and gripping the hammer. In addition, the testing machine is equipped with multiple protective measures, greatly improving the safety of operators and equipment usage. This machine is a commonly used testing instrument for pipeline steel manufacturers, large steel mills, steel research institutes, and other enterprises and research institutions.
Overall parameters:
1. Equipment composition and function description:
The testing machine is composed of three units: Host, feeding and returning system and control system. This testing machine is mainly used for drop weight tear test of pipeline steel, namely DWTT test. The machine adopts GB8363-87 Drop Weight Tear Test Method for Ferritic Steel as the main design basis.

2. Meet the standard:
ASTM E604-83 Standard test method for dynamic tear testing of metallic materials
ASTM E436-03 Standard Test Method for Drop-Weight Tear Tests of Ferritic Steels
API RP*5L3-96 Drop-Weight Tear Tests on Line Pipe
(It can also be designed according to the test method or detection method provided by the user according to special needs.)
