Flange forgings of petrochemical ring are the key parts in the field of petrochemical industry, and their sealing performance has an important impact on the normal operation and service life of equipment. In order to ensure that the sealing performance of petrochemical ring flange forgings meets the requirements, this paper will introduce the methods and steps of sealing performance testing.
The purpose of the sealing performance test is to verify whether the sealing performance of the petrochemical ring flange forgings meets the design requirements, to discover and solve potential sealing problems in time, and to ensure the safety and stability of the equipment during operation.
Method of sealing performance test
Bubble method: Inject a certain amount of liquid into the petrochemical ring flange forgings, and observe whether the liquid has bubbles inside the seal. If bubbles are generated, it indicates that the sealing performance is poor and needs to be adjusted or replaced.
Pressure difference method: Apply a certain pressure difference at both ends of the petrochemical ring flange forging, and observe the change of the pressure difference. If the pressure difference changes greatly, it indicates that the sealing performance is poor and needs to be adjusted or replaced.
Gas leakage test method: Gas or liquid is injected into the petrochemical ring flange forgings through a certain pressure to observe whether there is leakage phenomenon. If there is leakage, it indicates that the sealing performance is not good and needs to be adjusted or replaced.
Steps of sealing performance test
Prepare test equipment: Select the appropriate test equipment according to the test method, such as a bubble meter, pressure gauge, and air leakage detector.
Install the test equipment: Install the test equipment on the flange forgings of the petrochemical ring to ensure that the installation is firm and stable.
Test: test according to the specified test methods and steps, record the test data.
Analyze the test results: Organize and analyze the test data to determine whether the sealing performance of the petrochemical ring flange forgings meets the requirements.
Take measures: If the test result does not meet the requirements, take measures to adjust or replace the device in time to ensure the normal operation and service life of the device.
This paper introduces the testing method and procedure of sealing performance of flange forgings of petrochemical ring. Through the sealing performance test, potential sealing problems can be discovered and solved in time to ensure the safety and stability of the equipment during operation. At the same time, it is also necessary to strengthen the training and management of relevant personnel, improve their awareness and attention to the sealing performance test, and jointly maintain the good state of the petrochemical ring flange forgings.
