Detection Content

Detection Purpose: Inspect the plastic deformation ability of circular cross section metal tube and show its defects

Detection range: Seamless steel pipe, welded pipe

      Flattening test is a test tube in a given condition down flat deformation and crack defects of ultimate plastic deformation capacity, the principle is to the specified length in the direction perpendicular to the axis of the vertical tube sample or metal tube, a pressure was to force f, until in the distance between the two pressure plate under the action of the force reach the value stipulated in the relevant product standard.
