Seamless Steel Pipe Dimensional Tolerances: OD and Wall Thickness Standards Explained
Dimensional accuracy is one of the most important quality indicators for seamless steel pipes used in boilers, heat exchangers, petrochemical plants, refineries, power stations, and pressure piping systems. Even when the material grade and mechanical properties meet specifications, excessive deviations in outside diameter (OD) or wall thickness can affect installation, welding, pressure performance, and service life. This article explains the dimensional tolerance requirements commonly applied to hot-finished and cold-finished seamless steel tubes.
