Equipment Overview:
Wanjian metal drop hammer notch press is a special equipment attached to the drop hammer tear testing machine, according to the corresponding standards to press DWTT drop hammer tear sample notch。
Adopts hydraulic transmission, electric control, and uses electromagnetic reversing valve to control cylinder lifting。Equipped with a stroke switch, when the pressing gap reaches the specified depth, it can be automatically shut down, and there will be no damage to the sample and the testing machine when the manual valve is controlled。The press tool adopts high-quality W18Cr4V tool alloy material, which is not easy to wear and has a long service life。At the same time, the machine can also be used for flattening pipeline steel samples。The equipment is stable and reliable, easy to operate, high sample preparation efficiency, and is the best supporting equipment for drop hammer tear testing machine。
Relevant standards:
(1)GB/T 8363 "Ferrite steel drop hammer tear test method"
(2)GB 1814-79 "Steel Fracture Test Method"
(3)API RP*5L3-96Conducting Drop-Weight Tear Tests on Line Pipe
(4)ASTM E 436-03 Standard Test Method for Drop-Weight Tear Tests of Ferritic Steels
