    The user can provide samples of various internal coatings (including no internal coating and iron series phosphating coating) by the steel barrel manufacturer, conduct the compatibility immersion test under similar environmental conditions for storage and transportation for more than 6 months, analyze whether the coating changes and whether the pigment contained in the coating is dissolved, and then the user can determine and select the appropriate type of internal coating. There is no inner coating, and the surface is protected by mineral oil. Please pay attention to the impact on your product.
