Steel Ring Stiffness Testing Machine

1. Performance Characteristics:
• Suitable for testing metal pipes, welded steel pipes, seamless steel pipes, FRP, and other materials under flattening conditions.
• Four-column frame design ensures high rigidity and compact structure.
• High-speed bi-directional hydraulic cylinder allows for a wide range of stroke adjustments, improving testing efficiency.
• Advanced pressure servo technology enhances energy efficiency in the hydraulic system.
• The GDW series is an economical choice for flattening tests, featuring a scale plate between the upper and lower platens to measure deformation manually.
• The GDW-Z series offers intelligent control through computer operation. It automatically stops when the set deformation value is reached and displays test data while plotting curves in real time.
 
2. Applications:
• Metal pipes
• Welded steel pipes
• Seamless steel pipes
• FRP (Fiberglass Reinforced Plastic)

3. Basic Operating Procedures:
3.1 GDW Series Ring Stiffness Testing Machine
i. Place the pipe specimen on the lower platen.
ii. Operate the machine to start the test. Observe the scale plate between the upper and lower platens to monitor deformation.
iii. When the desired deformation is achieved, manually stop the test.

3.2 GDW-Z Series Computer Controlled Ring Stiffness Testing Machine
i. Place the pipe specimen on the lower platen.
ii. Enter the specimen dimensions (such as outer diameter and wall thickness) into the software, set the required deformation, and click "Begin."
iii. The machine starts automatically. The software displays test data and plots curves in real time. You can also adjust the testing speed via the computer.
iv. The machine will automatically stop once the set deformation value is reached.
v. After the test, the upper platen returns to its initial position, ready for the next test.
