Analyzed in the essay are the problems staying with long-term open air storage of steel pipes in dry weather areas and high yearly precipitation areas of the country. Accordingly specific measures for solution are put forward. Based on the analysis it is identified that at present due to long-term open air storage, there exist such problems with steel pipes as surface rusting, out-of-tolerance wall thickness and ovality, ageing of anti-corrosion coating and warping etc., preventive measures are proposed to be taken, including using solid, durable and opaque covering to protect the pipes from very beginning of storage, and mean while keeping surface of the pipes well ventilated, getting the pipes properly supported during the storage, removing end protectors off the pipes, and specifying appropriate stacking layers.
