1, the purpose,To ensure that the factory production of the API Spec5L pipeline steel pipe in the transportation, the loading method and the necessary protective measures, in order to prevent the steel pipe products in the pipe damage, wear or bruised and longitudinal fatigue crack unnecessary bad loss, on the basis of domestic SY/T 6577.1 2003 Pipeline steel pipe part 1 by rail and SY/T 6577.2 2003 "pipeline steel pipe transportation part 2 inland and Marine transportation, such as standard, and refer to the API Spec5L1-2002 version 6" pipeline steel pipe recommendations practical regulation of railway transportation, such as standards formulated procedures. 

2, the applicable scopeThis applies to discipline in accordance with the requirements of contract to supply by our factory is responsible for the carrier, and meet the following conditions of steel pipe products:1 and choose the length of the longer specifications for 2 "? In the 5 l steel pipe with pipe transportation;(2) the load stress applies only to the diameter and thickness ratio (D) > 50 API pipe steel pipe;(3) both the coating and the coating steel pipe, but does not include avoid loading method of steel pipe coating damage. The factory production of pipeline steel pipe carrier by the customers themselves or entrust a specialized logistics company transport, outside the scope of transportation of the steel pipe products is not in the scope of this discipline control. 

3, reference standardSYT 6577.1-2003 "pipeline steel pipe part 1 by rail);SYT 6577.2-2003 "pipeline steel pipe transportation part 2 inland and sea shipping". API 6 Spec5L1-2002 edition of the pipeline steel pipe recommendations practical regulation of railway transportation.
