### **Performance Characteristics**
- Perfectly suitable for metal pipe, welded steel pipe, seamless steel pipe, and FRP flatting tests.
- Four-column frame structure ensures superior rigidity and compact design.
- High-speed bi-directional hydraulic cylinder allows for wide stroke adjustment, improving test efficiency.
- Advanced pressure servo technology enhances energy efficiency.
- The GDW series offers an economical solution for flatting tests, with a scale plate between the upper and lower platens to measure deformation manually.
- The GDW-Z series is an intelligent option, allowing computer control. You can set deformation values in the software, and the machine will automatically stop once the target is reached. It also displays real-time data and draws test curves.

### **Basic Testing Operation**
#### **3.1 GDW Series Ring Stiffness Testing Machine**
1. Place the pipe specimen on the lower platen.
2. Operate the testing machine to start the test. Observe the scale plate between the upper and lower platens to monitor deformation.
3. When the desired deformation is achieved, manually stop the test.
#### **3.2 GDW-Z Series Computer Controlled Ring Stiffness Testing Machine**
1. Place the pipe specimen on the lower platen.
2. Enter the specimen dimensions (such as outer diameter and wall thickness) into the software. Set the required deformation value and click "Begin."
3. The machine starts automatically. The software displays test data in real time and draws the test curve. You can adjust the test speed via the computer.
4. When the deformation reaches the set value, the machine stops automatically.
5. After the test, the upper platen returns to its initial position, ready for the next test.
