| Process |
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 the steel 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.
