Description
The welded seam pipe production line with submerged arc is a product of recent development and patented by our company. This CFOE factory is composed of a carriage winder, unwinder, straightener, side guide unit, butt welding machine, edge turning machine, plate cleaning unit (optional), main motor, pre-bent unit, machine formed, internal welding unit, external welding unit, online ultrasonic tester, cutting unit, etc. This straight seam welding machine with submerged arc is also called the CFOE machine. CFOE stands for continuous and flexible formation of straight seam pipes with submerged arc.
features
- The pipe welding production line has a continuous production, so there is no need to change the coils if they do not need to be changed by the roughness.
- The quality of said machine is reliable in sewing welding technology.
- The pipe produced by the pipe welding machine for the welding of straight seam pipes with submerged arc is usually used for the protection of oil and gas. This machine has a good market perspective.
- This machine has great advances such as the low cost of production and a large production capacity.
- The CFOE machine is able to overcome the problem of competing with the JCOE machine, due to its low production capacity and high costs.
- Compared with ERW, it is easier to control the quality and power consumption of the machine for welding welding of straight seam pipes with submerged arc.
- The welding seam of the pipe welding production line exceeds the resources of the long weld seam and the difficulty of the inspection incorporated into the spiral welding seam. Compared with UOE and JCOE, the investment and the cost are lower.
- The tube welding machine can be the complement for the JCOE machine because it is hard and more economical than the UOE and JCOE to produce pipes with a diameter range of Φ219 to Φ711.
