| Process |
The three main forming steps of the UOE LSAW pipe forming process include: steel plate pre-bending, U forming and O forming. Each process
uses a special forming press to complete the three processes of steel plate pre-bending, U forming, and O forming in sequence, so that the steel
late is deformed into a round tube.
After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, and then the other half of thesteel plate is pressed into a "J" shape to form a "C" shape, and finally an open "O" is formed by pressing from the middle Type tube blank.
When transporting, loading and unloading longitudinal submerged arc welded pipes, special hoisting and transportation tools should be used
to avoid scratching the surface.
