The standard for the boiler tube ball test diameter is 98% of the inner diameter of the tube wall, usually not less than 32mm.
What is the boiler tube ball test?
The boiler tube ball test refers to the use of a spherical metal device (ball passer) to pass a metal ball through the boiler tube in a certain way to detect the patency of the boiler tube and whether the wall thickness inside the tube is uniform and other defects in the tube. The boiler tube ball test is an effective method to inspect the quality of boiler tubes and an important engineering technology test.
Requirements for the diameter of the boiler tube in the ball test
The ball test has high requirements for the diameter and wall thickness of the boiler tube, because the purpose of the test is to inspect the patency of the inside of the tube and the quality of the tube. In general, the diameter of the tube for the ball test is 32mm or more. If the inner wall of the tube is uneven, oxidized, damaged, etc., it must be repaired in time.
Standard for the diameter of the boiler tube ball test
The standard for the diameter of the boiler tube ball test is 98% of the inner diameter of the tube wall, usually not less than 32mm. This is the standard requirement for the diameter of the boiler tube in the ball test. The size of the boiler tube diameter and other quality issues of the pipeline directly affect the service life and maintenance cost of the boiler.
Conclusion
The boiler tube ball test is of great significance for the quality inspection of boiler tubes. The ball test requires 98% of the inner diameter of the tube as the standard, usually not less than 32mm. Only boiler tubes that have undergone strict inspection can ensure the normal operation of the boiler, while also reducing maintenance costs and increasing the service life of the boiler.
