Good packing makes us get praise from customers

When customers receive our flanges, the first thing they notice is definitely the outer packaging of the flange, and then they are observing whether they are intact, and finally the quality. So what are the issues in the flange packaging?

There are two types of flange: metal flange and non-metal flange. Before long-term storage, the metal flange shall be coated with grease and the storage space shall be dry to prevent rust. Each flange should be stored separately, because the metal materials of different materials and batches will be corroded and rusted quickly due to the electrochemical effect. Nonmetal flange is generally used for anticorrosion, it will not rust itself, but it should be prevented from mechanical damage and deformation.
