Quality and tolerances as per EN 1057, EN 12735, EN12449 or other world standards, as well as special requirements, (special mechanical properties, narrower technological characteristics, stricter tolerances, specific surface quality requirements, etc.), which are defined by special technical conditions. We can also produce tubes against submitted samples, in case precise quality and tolerances data are missing.
