The EN10216 series standards is a commonly used specification for seamless steel tubes for pressure purpose. Grades P235 tubes shall be manufactured by a seamless process. P235 TR1 and P235 TR2 specified in EN10216 part 1 supplied by quality in the hot-formed process. The TR1 is as formed or normalized or normalizing-formed, the TR2 is normalized or normalizing-formed, but for the hot-formed and cold-finished process, TR1 and TR2 shall be normalized. The P235GH is specified in EN10216 part 2 for the elevated temperature(880℃-940℃) applications.
