Requirements for seamless pipe straightness tolerance
Seamless pipes (SMLS) are widely used in industrial applications, and straightness is a key quality parameter. In general, seamless steel pipes are expected to maintain a certain degree of straightness; otherwise, deviations may negatively affect their performance. To ensure consistent quality, national standards have been established to define acceptable straightness criteria for seamless pipes. This article provides a detailed overview of these standards.
