Flange forgings of petrochemical ring are important parts in the field of petrochemical industry, and their pressure resistance has an important impact on the normal operation and service life of equipment. In order to ensure that the pressure resistance of petrochemicals ring flange forgings meets the requirements, this paper will introduce the methods and steps of the pressure test.
The purpose of the pressure test is to verify that the pressure performance of the petrochemical ring flange forgings meets the design requirements, timely discover and solve potential pressure problems, and ensure that the equipment can maintain stability and safety when under pressure.
Method of withstand pressure test
Hydraulic test: A certain amount of liquid is injected into the petrochemical ring flange forgings, and its pressure resistance is tested by increasing the pressure of the liquid. Hydraulic test can simulate the pressure environment in actual operation, and carry out comprehensive pressure test on the flange forgings of petrochemical ring.
Air pressure test: by filling a certain pressure of gas into the petrochemical ring flange forgings, observe its performance under gas pressure. Pressure test can be used to test the pressure resistance of flange forgings of petrochemical ring under gas medium.
Steps of pressure test
Prepare test equipment: Select the appropriate test equipment according to the test method, such as hydraulic pump, air pump, pressure gauge, etc. Ensure equipment is in good condition and calibrated according to regulations.
Install the specimen: Install the flange forgings of the petrochemical ring on the test equipment to ensure that the installation is firm and stable.
Perform pressure test: Perform pressure test according to the prescribed test methods and steps, and record the test data. During the test, we should pay close attention to the deformation and leakage of the specimen to ensure the safety of the test.
Analysis of the test results: the test data are sorted and analyzed to determine whether the pressure resistance of the petrochemical ring flange forgings meets the requirements. If it is found that it does not meet the requirements, it is necessary to take measures to adjust or replace it in time.
This paper introduces the pressure test method and procedure of flange forgings of petrochemical ring. The pressure resistance of flange forgings of petrochemicals ring can be evaluated comprehensively through the pressure resistance test, and the potential problems can be found and solved in time. At the same time, it is also necessary to strengthen the training and management of relevant personnel, improve their awareness and attention to the pressure test, and jointly maintain the good state of the petrochemical ring flange forgings.
