Static Constant Loading Tester
Static Constant Loading Tester is mainly used to determine the resistance to the axial static constant load of plastic manhole. A constant force is steadily loaded on the axial direction of the manhole for the specified time, when the test is finished, observing the sample appearance (deformation, collapse, crack or crazing), determine the deformation in axial direction and calculate the deformation ratio of manhole. The machine is also suitable for ring stiffness test, flattening test, ring softness test of thermoplastic pipes.
