Each processuses a special forming press to complete the three processes of steel plate pre-bending, U forming, and O forming in sequence, so that the steellate 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. Packaging & ShippingWhen transporting, loading and unloading longitudinal submerged arc welded pipes, special hoisting and transportation tools should be usedto avoid scratching the surface. FAQQ1.
