Zn Al Mg Coating Round Steel Pipe Making Process
The manufacturing process of Zn Al Mg Coating Round Steel Pipes mainly includes the following steps:
unwinding of zinc aluminum magnesium coated steel coils ->edge cutting and welding ->straightening ->tray storage ->roller cold forming ->high-frequency welding ->removal of excess welding bars ->water cooling ->sizing ->cutting ->detection（Pick out the unqualified joint pipes） ->spraying and storage
