PC Strand Testing Machines
Steel Wire Repeated Bend Testing Machine
UNIVER WRB-10 Series Steel Wire Reverse Bend Testing Machine meets the growing demand for accurate and repeatable reverse bend testing of metallic materials in accordance with specifications. They are ISO 7801, ‘Metallic materials — Wire — Reverse bend test’. NF A03-010 ‘Les matériaux métalliques. Wire. inverse pliez’.
PC Strand Tensile Stress Relaxation Testing Machine
UNIVER RELAK Series is used to determine stress-relaxation of metal, such as Prestressed concrete strand, Prestressed concrete bar, steel rope and so on., the specimen is deformed a given amount and decrease in stress is recorded over prolonged period of exposure at constant elevated temperature.
PC Strand Tensile Stress Corrosion Testing Machine
Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected sudden failure of normally ductile metals subjected to a tensile stress, especially at elevated temperature in the case of metals.
PC Strand Axial Load Fatigue Testing Machine
UNIVER PULTEK Series PC Strand Axial Load Fatigue Testing Machine is specially designed to conduct axial load fatigue test on strand according to ISO 15630-3, the axial load fatigue test consists of submitting the strand to anxial tensile force, which varies cyclically aoccording to an sinusoidal wave-form of constant frequency, f, in the elastic range. the test is carried out until failure of the strand or until reaching, without failure, the number of load cycles specified in the relevant product standard.
PC Strand Deflected Tensile Testing Machine
UNIVER DTT-500 PC Strand Deflected Tensile Testing Machine is specially designed for defected tensile test on wire strand according to ISO 15630-3, this test method is to determin the reduction coefficient of the maximum force in uniaxial tension due to a deviation of 20degree around a specified mandrel.
