Precision High Frequency Welded Tube Making Machines

Steel tube making machine is the main equipment for the welded tube production line. Pipe diameter of the finished products is 7.5 mm to 720 mm and wall thickness is 0.3 mm to 45 mm. Production line for welding tube is composed of uncoiler, leveling machine, butt welder, loop, straightening machine, high frequency equipment, etc. Its operating process is that after rolling the strip or plate, this machine welds the tube into steel pipe by HF welding or submerged-arc welding.

Steel tube making machine is mainly used for making electric heating tubes, refrigerator pipes, automobile frame pipes, fitness equipment pipes, furniture tubes, pipes for cooler, API pipes, pressure transmission pipes, architectural pipes, structural pipes, etc.

Complete line of steel tube making machine includes double side uncoiler, horizontal accumulator, main machine (includes forming machine, roller system of forming, seam guide, high frequency induction welding machine, roller system for moving, burr removing frame, water cooling system, sizing machine, roller system of leveling, speed testing wheel and Turkish frame), auto flying saw, electric control equipment and high frequency welding machine.

Production Technique Drawing

Detailed production process of steel tube making machine:
Uncoiling → shearing and butt welding → material accumulating → flattening→ forming system → high frequency induction welding machine → inside and outside burr removing frame → water cooling system → sizing system → leveling system → speed testing → Turkish frame → saw cutting → running out table
