JJHBDT-S Hydraulic Bending Tester


This instrument is a hydraulic bending deflection angle test unit for the comprehensive performance test platform of thin-walled stainless steel pipes and fittings. The test pressure is provided through the hydraulic control system, and it is used to test the water pressure bending deflection angle performance of thin-walled stainless steel pipes and fittings after they are connected. , Evaluate the connection performance of the pipe fittings.


JJHTS-S Hydraulic Pressure Tester (host)


This instrument is the core of the hydraulic test control of the comprehensive performance test platform for thin-walled stainless steel pipes and fittings. It can be used for multiple hydraulic performance test units, multiple water pressure test units, multiple hydraulic vibration test units, and multiple bending angles at the same time. Test units, multiple hydraulic torsion test units, multiple maximum expansion and contraction test units, multiple deflection angle test units, and multiple vibration strain test units provide accurate test pressures.
