| Elbow detection machine is a kind of equipment used to detect pipe elbow, mainly used to detect whether the welding quality, dimensional accuracy and shape of the elbow meet the design specifications and requirements. Correct operation procedures can ensure accurate and reliable test results. The following details the operation steps of the correct detection elbow machine.
1. Preparation before testing
1. Collect relevant information, including elbow design drawings, standards, process documents, etc.
2. Prepare the elbow testing machine, including the trolley, electrical control box, measuring instruments, fixtures, etc.
3. Prepare the auxiliary materials required for testing, including cleaning agent, oxygen, acetylene, etc.
4. Determine the testing environment and staff to ensure that the testing environment is clean and well-ventilated.
5. Check whether the equipment is intact and adjust the parameters of the equipment to ensure that the test report issued is accurate and reliable.
Second, install the fixture
1. Place the elbow on the fixture bracket to ensure that the fixture is smooth, vertical and stable.
2. Adjust the fixture to ensure that the installation position, Angle and height of the elbow are correct.
3. Use a wrench or other tools to fix the nuts and bolts of the fixture to ensure that the fixture is stable and firm to avoid errors in the detection process.
4. Check whether the fixture is tightly fitted to the elbow to avoid air leakage and other adverse phenomena between the fixture and the elbow, which will affect the detection result.
Iii. Preparation of testing equipment
1. According to the pipe diameter and wall thickness of the tested elbow, select the appropriate testing equipment, including X-ray, ultrasonic, magnetic powder, etc.
2. Assemble testing equipment, including radioactive sources, detectors, displays, etc., to ensure the normal operation of the equipment.
3. Set the corresponding detection parameters, including detection, sensitivity, location and Angle of the radioactive source, etc., to ensure the accuracy and precision of the detection results.
4. Connect the corresponding measuring instruments and cables to check the stability and reliability of the electrical equipment.
4. Test operation
1. Stable operation, check whether all operators wear personal protective equipment correctly, and ensure safe operation.
2. Carry out basic inspection on the surface of the elbow machine to check whether the surface has abnormal phenomena such as leakage, distortion, crack and splitting. It will be recorded on the test report.
3. According to the design requirements, adjust the parameters to detect the elbow. If multiple segments are detected consecutively, ditto.
4. The monitoring and testing instrument runs stably, and the corresponding probe and detection technology are selected to detect the elbow. During the testing process, the equipment is calibrated and checked at regular intervals to ensure the reliability of the test results.
5. According to the selected detection method, the key parameters of the weld, wall thickness, circumference, ellipticity, surface parallelism and so on of the elbow are tested.
6. When a problem is found, the equipment parameters should be adjusted in time and re-detected until the design requirements are met.
5. Test data processing
1. Record the test data, including the size, shape and comparison standard of the elbow, to ensure that the test results are well documented.
2. According to the situation of the detected elbow, the test results are processed and analyzed, including whether the elbow is qualified or not, the type and degree of defects, etc.
3. According to the test results, issue a certificate of conformity or defect report. Submit the test report to the relevant department for further processing and maintenance.
4. Clean, maintain and maintain the testing equipment to ensure the normal use of the equipment.
In SUMMARY:
These steps must be carried out in strict accordance with the procedure to ensure that the test results are accurate, reliable and true. At the same time, more attention should be paid to the maintenance and maintenance of testing equipment, which will be conducive to the life extension and operation efficiency of the equipment.
