How should the longitudinal and circumferential seams of the skirt be classified as welds? Sometimes the importance of the skirt base is no less than that of the cylinder
The longitudinal and circumferential seams of the skirt should generally be treated in accordance with the welding requirements for the cylinder. Since the skirt bears the weight of the tank and is subjected to high pressures and vibrations during operation, the quality of these welds is directly related to the safety and stability of both the skirt and the entire tank. Therefore, for the longitudinal and circumferential seams of the skirt, the same welding processes and inspection methods as those used for the cylinder body should be employed to ensure that the quality of the welds meets the design requirements and can satisfy the operational requirements. Sometimes, the importance of the skirt base may be no less than that of the cylinder, and therefore it should also receive sufficient attention in design and manufacturing. .
