How to extend the service life of flange?
Flange as steel products are easy to rust corrosion, which will shorten its service life. So we should pay attention to the surface anti-corrosion of flange.
Lately, a new customer sent me an inquiry. During the communication, he told me that there was a large area of rust after the flange bought by another company arrived, as shown below.
The reason for this may be that the surface anti-rust oil of the flange is not well coated, coupled with a long time during the shipping process of the damp environment caused the flange to rust. In this case, we suggest that he can polish the flange surface with sandpaper or other tools to remove most of the rust.
As a professional flange supplier Heibei Haihao Group, we will first give corresponding suggestions on the surface anti-corrosion of the flange according to the location of the customer and the voyage of the ship. For example, eastern European and Russian flanges are usually painted with anti-rust oil, Japanese standard flanges are painted yellow, American flanges are painted black…
In addition, some customers will have special requirements for flange anti-corrosion coating. For example, we had a client in Brazil who bought flanges, pipe fittings and other products for the construction of chemical plants located on saline-alkali land. Because its use environment is more prone to corrosion, so it is required to use 3PE coating on flange and fittings, in order to ensure the service life of flange and other products in special circumstances.
