How to ensure the safety of the building?---Hydraulic univesal tensile testing machine

          As you know, we sometimes hear about major building collapses. Let me tell you about a case in which 12 people were injured and 6 fishermen died when a bridge in the south of yilan county in Taiwan collapsed.As soon as this matter was disclosed, it attracted attention from all over the country.
          He average bridge is based on 50 years of use, but the Southern Australia Cross-Harbour Bridge has been in use for only 20 years. This should not happen. The investigation personnel initially understood that it was judged from the current image data and related information that one of the steel cables connecting the vault and the bridge deck broke, and the other cables caused the other cables to break, which made the supporting force of the bridge deck insufficient.

          According to reports, the former director of the "Earthquake Engineering Research Center" in Taiwan and the current consultants analyzed by experience that there are several reasons for the cable fracture. The first is the lack of ‘sufficiency’ in bridge design. He said that the margin is the ability to reserve excess strength during construction. The second is the repair and maintenance of the bridge.

          He further stated that the bridges generally built on the beach, in addition to considering the degree of earthquake resistance and weight tolerance, will strengthen the ability to resist sea breeze corrosion and avoid damage to the bridge due to corrosion. In addition, metal fatigue may be one of the causes of wire rope fracture.
          So how can we ensure the stability and safety of building materials to the greatest extent? Now, I will introduce to you.
          Metal testing is a process or procedure used to check composition of an unknown metallic substance. There are destructive processes and nondestructive processes. Metal testing can also include, determining the properties of newly forged metal alloys. When using metal parts in your products or projects, you need to be certain that they are safe, reliable and meet rigorous regulatory standards. Our metal testing services help you identify and assess the characteristics of your metal parts to determine their safety, reliability and integrity. We can provide you with equipment to test the quality of materials.

          Hydraulic univesal tensile testing machine uses the motor to drive ball screw to move fixture. Place the fixture with sample between the upper and lower fixture, use a given speed to pull sample upward by upper fixture. Load cell above upper fixture will sense tensile strength, and convert the strength into voltage sign and output to the display screen. This series of Tensile Tester is widely used in wires & cables, hardware, metal and so on, for tensile strength, bend strength, ect.
