Seamless Cylinder Flattening Test Method (GB 13440-92)
This article provides a summary of the Seamless Cylinder Flattening Test Method, as specified in GB 13440-92. It will discuss test procedure, safety considerations, and quality control.
The Seamless Cylinder Flattening Test Method, as specified in GB 13440-92, is a way to evaluate the quality of seamless cylinders. The test measures the amount of flattening that a cylinder is able to withstand when placed under a certain pressure. The test is typically applied to cylinders made of 120N4-xo series steel, or equivalent, of a nominal outside diameter of 210 to 800 mm.
Test Procedure
The test procedure is relatively simple. Place the cylinder between two flat plates and position it so that the direction of flattening is perpendicular to the cylinder axis. Connect the plates to the appropriate device, and mount it to the testing machine. Install the pressure device and the loading device, and make all necessary settings. Test to the specified pressure, recording maximum load when flattening begins.
Safety Considerations
Safety considerations must also be taken when performing the Seamless Cylinder Flattening Test. Care should be taken to ensure that all hydraulic lines and connections are securely fastened, and that all personnel are wearing the necessary personal protective equipment. Additionally, the testing chamber should be clear of any combustible materials and free of debris to minimize potential hazards.
Quality Control
Quality control should also be taken into consideration when performing the Seamless Cylinder Flattening Test. To ensure an accurate test result, the cylinder should be checked for surface defects and the testing machine should be calibrated periodically. Additionally, it is important to regularly check the loading device to ensure that it is properly calibrated.
Conclusion
The Seamless Cylinder Flattening Test Method, as specified in GB 13440-92, is a way to evaluate the quality of seamless cylinders. The test procedure is relatively simple and involves positioning the cylinder between two flat plates and then measuring the load when flattening begins. Safety and quality control considerations should be taken into account when performing the test.
