Question 338General Subjects - QMED

The correct answer is B) be certain that the flanges line up squarely. Before making up a flanged joint, it is critical to ensure that the flanges are properly aligned and square to each other. This is necessary to create a tight, leak-free seal when the joint is bolted together. Misaligned flanges can cause uneven stress on the gasket, leading to potential leaks or even damage to the flanges themselves. The other answer choices are incorrect because: A) cutting grooves in the flange face is not a recommended practice, C) heating the pipeline to expand the bolt holes is unnecessary, and D) having a spare gasket on hand, while a good practice, is not directly related to the flange alignment.
