Abstract: Briefed here in the article is the epoxy powder external coating process for steel pipes.Focused on is a comparative analysis between the Chinese standard SY/T 0315-2013 and the Canadian standard CSA Z 245.20-2014, involving such aspects as applicable scope, performance requirement, production control, and quality inspection, etc.It is identified via the analysis that for items that need a rather long inspection cycle like 28 d cathodic disbanding and 28 d adhesion, etc.it is relatively easy to adapt the method as described under SY/T 0315-2013, and that for the timeliness of the results from inspections of the powder performance, and the coating quality of the specimen in the lab, and for control of the interfacial contamination in the type inspection during the production process, there is no requirement as specified under SY/T 0315-2013.
