Dipping method: used for parts that can be put into the pickling tank or passivation tank, but it is not suitable for large equipment. The pickling solution can be used for a long time, with high production efficiency and low cost; large-volume equipment is filled with acid solution and immersion liquid consumption Too big.
Brushing method: suitable for the internal surface and local treatment of large-scale equipment. Physical operation, poor working conditions, and acid liquid cannot be recovered.
Paste method: used for installation or maintenance site, especially for welding part processing manual operation, poor working conditions, high production cost.
Spray method: It is used at the installation site. The inner wall of the large container has low liquid consumption, low cost and high speed, but it needs to be equipped with spray gun and skewer ring system.
Circulation method: Used for large-scale equipment, such as heat exchangers, tube and shell treatment. It is easy to construct and the acid can be reused. It requires piping and pump to connect to the circulation system.
Electrochemical method: Not only can be used for parts, but also can be used to brush the surface treatment of field equipment. The technology is more complicated and requires a DC power supply or a potentiostat.
