Steel Ring Stiffness Testing Machine
1.   Performance Characteristics:
l  Ideal for testing metal pipes, welded steel pipes, seamless steel pipes, FRP, and other materials under flattening conditions.
l  Four-column frame design ensures high rigidity and compact structure for stable performance.
l  Equipped with a high-speed bi-directional hydraulic cylinder that allows for wide stroke adjustment, improving testing efficiency.
l  The hydraulic system uses pressure servo technology for better energy efficiency and control.
l  GDW series is an economical choice for basic flattening tests. It features a scale plate between the upper and lower platens for manual deformation measurement. Once the desired deformation is reached, the test can be stopped manually.
l  GDW-Z series offers intelligent control via computer. The software allows users to set deformation values and automatically stop the test when the target is reached. It also displays real-time data and draws test curves for better analysis.
  
2.   Applications:
l  Metal pipes, welded steel pipes, seamless steel pipes, FRP (Fiberglass Reinforced Plastic) and similar materials.

3.   Basic Testing Operating:
3.1  GDW Series Ring Stiffness Testing Machine
i.          Place the pipe specimen on the lower platen.
ii.          Start the test using the machine’s controls. Observe the scale plate between the upper and lower platens to monitor deformation.
iii.          Stop the test manually once the desired deformation is achieved.
 
3.2  GDW-Z Series Computer Controlled Ring Stiffness Testing Machine 
i.          Place the pipe specimen on the lower platen.
ii.          Input the specimen dimensions (e.g., outer diameter, wall thickness) into the software. Set the required deformation value and click "Begin."
iii.          The machine starts automatically. The software will display test data and generate test curves in real time. You can also adjust the test speed from the computer.
iv.          When the deformation reaches the set value, the machine stops automatically.
v.          After the test, the upper platen returns to its initial position, ready for the next test.
