Drop weight tear tester (DWTT) API RP 5L3

HUALONG WCJ Series is mainly used for drop weight tear test (DWTT) of Ferritic Steels, to observe specimen fracture surface after impact within the temperature that fracture type is converted from non-ductility to ductility. This test method is that hammer striker with some weights is raised to some height then released. Free drop hammer impacts and tears the specimen. After impact, observe shape and features of fracture surface.
Application range
This testing machine accords with the relevant requirements of Standards for DWTT such as: Metallic materials－Drop-weight tear tests of ferritic steels (GB8363-2007), ASTM E 436-2003 and APIRP 5L3-2003, EN 10274.
1. API RP 5L3 (Recommended)
2. ASTM E 436
3. EN 10274
4. GB 8363
The recommended practice API RP 5L3 issued by the American Petroleum Institute (API) describes the testing procedure to be used on large-drop impact testers. A specimen supported at both ends is impacted with a cold-press-fitted notch, with the point of impact opposite the notch. Since the specimen thicknesses are very large sections of actual pipeline tubes, high impact energies of up to 100,000 Joule are necessary to break the specimen.
