What is the processing technology and process of galvanized seamless steel pipe?

The processing technology and process of galvanized seamless steel pipe mainly include the following steps:

Selection and pretreatment of raw materials: The raw material for the production of galvanized seamless steel pipe is seamless steel pipe, and it also needs to be equipped with corrosive media, stabilizers and other substances. After entering the production workshop, the raw materials need to be pickled to remove the oil and rust on the surface, making the surface smoother for subsequent processing.

Alkali cleaning: Put the steel pipe into the sodium hydroxide solution, so that the metal salt and iron hydroxide products and iron hydroxide dissolves slowly appear on the surface. These metal precipitation and iron hydroxide substances will reduce the depletion of the passivation film. The degree of oxidation, followed by washing can get a clean surface.

Electroplating: Soak the cleaned seamless steel pipe in the electrolytic tank, add a stabilizer, and indirect contact with the zinc plate of the other electrode. Under the action of direct current, through electrochemical processes such as anodic oxidation and electrolytic deposition, the zinc metal Deposit on the surface of seamless steel pipe to form a uniform thickness and dense zinc layer.

Inspection and packaging: After a series of processes, the galvanized seamless steel pipe needs to go through multi-step inspections to ensure its quality; the packaging work must also be carefully implemented to prevent damage during long-distance transportation.
