Φ219 Φ711 CFOE mill is the newest product in our company, which adoptsCFOE patent technology from our company. CFOE means continuous flexible formingand straight seam submerged arc welded pipe. There are special advantages inthe mill. The mill is continuous production, which is no need to change therollers in rough-forming section when the specification needs to be changed.Compared with ERW, the quality and energy consumption of CFOE is easier to becontrolled, and is welded better and low consumption. The welding seam of CFOEovercomes the shortages of long welding seam and difficult inspection on spiralwelding seam after inbuilt. Compared with UOE and JCOE, the investment cost andproduction cost are low. The quality of CFOE welding seam is the best in allwelding seam technology.
CFOE is the most reliable, and there is no circularinterface welding seam on the pipe, which is easy to weld, inspect, maintainand repair. The pipe produced by the mill just covers most pipes which are currentlyused by oil, gas casing. The mill also has a good market prospect. Annualproduction capacity is 50,000-100,000 tons.
If there are smalldifferences between CFOE cost and spiral welded pipe cost, nobody will buyspiral welded pipe on high grade pipeline. CFOE welded pipe will replace fullyspiral welded pipe in high grade pipeline, and have a good market prospect.
CFOE can be the complementmill for the JCOE mill. Because it is hard and uneconomical for UOE and JCOE toproduce the pipes within the diameter range of Φ219～Φ711. There are outstanding advantages such as less productioncost and high production capacity. Due to low production capacity and over highprice of JCOE mill, which create the serious competition problem, it can makeup middle and large diameter in JCOE.

- Q: A roll forming machine, rolling out of the length is always not up to a fixed size, not too small, that is, more than that, what is the cause?
- Yes, the width of the bearing plate can be a deviation from the length.
- Q: What is rolling forming processing?
- Ironing the surface of the workpiece with a raised micro wave crest to fill the concave micro troughs, thus changing the distribution of the peaks on the surface, and obtaining smaller surface roughness values.
- Q: Improvement in rolling forming process
- Can not meet the slender rod, thin-walled tubes and other rigid parts of the processing.
- Q: Introduction of roll forming process
- Not only threaded fasteners industry applications, automobiles, bicycles and other industrial sectors also use rolling forming process, processing complex shapes of parts.
- Q: What kind of material and what heat treatment are used for pressing roller (molding, feeding, cutting force, heavy load, heavy load) of sheet steel rolling machine?
- Use 40Cr or 20Cr, Cr12.Cr12MoV, quenching and tempering treatment, think of hardness, high point, carburizing, nitriding, and consider adding lubrication device to extend its service life
- Q: What is the surface rolling forming machine process?
- Due to the rolling surface of metal plastic deformation, so that the surface microstructure of cold hardening and grain refinement, forming a dense fibrous, and the formation of residual stress, hardness and strength, so as to improve the surface wear resistance, corrosion resistance and compliance.
- Q: Process mould for rolling forming process
- Press forming is an advanced processing technology, and its remarkable characteristics have been paid attention to by the automobile industry at home and abroad.
- Q: Material and equipment for roll forming process
- The most common type of roll forming is reciprocating flat wire twisting machine. Therefore, for the manufacturers of cold heading machines and screw rolling mills, the design of rolling dies is only a matter of design.
