① Tensile test: measure stress and deformation, determine the strength (YS, TS) and plasticity index (A, Z) of the material
Longitudinal and transverse specimen pipe section, arc, circular specimen (￠10,￠12.5)
Small-diameter thin-walled steel pipes, large-diameter thick-walled steel pipes, and fixed gauge distance.
Remarks: The elongation of the sample after breaking is related to the size of the sample GB/T 1760
②Impact test: CVN, notch C type, V type, power J value J/cm2
Standard sample 10×10×55 (mm) Non-standard sample 5×10×55 (mm)
③Hardness test: Brinell hardness HB, Rockwell hardness HRC, Vickers hardness HV, etc.
④Hydraulic test: test pressure, pressure stabilization time, p=2Sδ/D
