What are the external quality requirements of Tianjin chemical steel barrel?

 

A product only has good internal quality, while the appearance quality is not good, it is not a good product. A product with good internal quality and good appearance quality is a good product. In order to ensure the quality of steel drums, when there are external requirements for packaging containers, regulations should be made, such as surface defect value, color uniformity and other indicators that need to be determined, and the external quality requirements of steel drums should be put forward.
The steel drum has defects such as irregular shape, haircut, mechanical damage and iron tongue at the edge of the roll. It is not only poor in appearance quality, but also unsafe and easy to hurt people. The mechanical damage of steel barrel will reduce the durability of steel barrel.
The irregularity of steel drums is mainly caused by production, turnover, loading and unloading, extrusion and knocking during transportation. Steel drums are thin-walled containers, which are easily deformed by external forces. Therefore, in the whole process of production, handling and use, it is necessary to carefully handle and take effective protective measures.
As a packaging container, the steel drum must be clean, rustless, slag-free and other impurities, so that the contents are not polluted, so as to ensure the quality of the contents.
