True or False: Slag inclusions on ASME code pipe must always be removed?

1. True

2. False

3. Only if they exceed a certain size

4. Only for pressure vessels

The correct answer is: False

The statement regarding slag inclusions on ASME code pipe being removed is considered false because while slag inclusions can be detrimental to the integrity of a weld, they do not always necessitate removal in every instance. The necessity for removal depends on various factors, such as the type of service the piping will be subjected to, the size and nature of the slag inclusions, and the overall impact on the weld quality and pipe performance. In many cases, if the slag inclusions do not compromise the structural integrity or fail to exceed acceptable limits established by industry standards, they might not require removal. This highlights the importance of proper inspection and adherence to guidelines that determine permissible defects within welded joints. Therefore, while slag inclusions are a concern in welding standards, it is not an absolute requirement for all cases to mandate their removal, leading to the conclusion that the statement is false.
