WCJ-1000000 Impact Testing Mahines For Drop Weight Tear Test Of Ferrite Steels With Buffer

• Bairoe WCJ Series is mainly used for drop weight tear test (DWTT)of Ferrite 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.
• ASTM: E436   Others: API RP 5L3   GB: T8363
• Application range
  This testing machine accords with the relevant requirements of Standards for DWTT such as: Metallic materialsDrop-weight  tear tests of ferrite steels.
• 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.

Features:

• Regulating impact energy by adjusting the lifting height and mass of the weights.
• Very robust construction stands up to the rigour of high energy testing to provide high reliability with a minimum of downtime.
• The buffer is equipped to absorb the residual energy after breaking the specimen to protect the weight and anvil from destroying. Also install the safe outfit, such as safety net, safe pin for main tenance and hanger locking.
• Easily interchangeable contact parts simplify maintenance and reduce cost of ownership.
• State-of-the-art testing accommodates impact energies up to 100,000J and specimens up to 40mm thick.
• Automated specimen loading provides compliance with cycle times required by test methods, while maintaining operator safety.
• Very rigid base and anvils ensures very low flexure under high test loads.
• Guided mass system to ensure that the impact geometry is correct throughout the entire test.
• Equipped with the specimen-carrying outfit, anti-falling of outfit for the specimen, centering outfit to guarantee quick, accurate and reliable tests.
• High quality, easy to use control software ensures consistency and enhances throughput.
• Ergonomically designed, no requirement for the operator to work at elevated heights or handle excessive physical loads.
• Optional liquid low temperature chamber.
• Optional automatic specimen feeding system.
• Responsive life-time technical support
