The introduction ofstraight seam HF welded pipe mill
The plate in certain width afterslitting line and stripping is unfolded and bent into pipe state. The edge ofthe steel plate is melted by making use of the proximity effect and skin effectof high frequency current. Then, the plate is extruded and welded into the pipeby extruding roller. Straight seam welded pipe mill also is called ERW mill.
The forming styles of straightseam welded pipe can be divided into roll
forming,cage forming, flexible forming, full auto flexibleforming. The mill developed by our company adopts roll forming when havingsmall diameter (Φ≤114) The cageforming is adopted when having middle or small diameter (Φ≤165). Full auto flexible forming is adoptedwhen having large diameter(Φ≤711).
According to the productsfunctions, straight seam welded pipe mills are divided into API model, nationalstandard model.
API model mainly produces highlevel steel pipes, such as delivery pipe of petroleum and natural gas, oil wellcasing and so on. The requirements for material and quality are very strict.The mill is equipped with section equipment and technological equipment, suchas IF annealing, air-cooled roll table, ultrasonic inspection, and highpressure hydraulic pressure testing machine, and drifter and so on.
National standard model mainlyproduces the steel pipe, such as water-gas pipe, structure pipe and so on.
- 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:Improvement in rolling forming process
- Can not meet the slender rod, thin-walled tubes and other rigid parts of the processing.
- 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 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?
- Non bonding wear of rolled material (especially stainless steel strip, etc.)
- 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:What is rolling forming processing?
- A special rolling tool is used to exert certain pressure on the surface of the workpiece so as to make the surface metal flow.
- Q:Material and equipment for roll forming process
- Rolling process is a cold forging process, which can be used for rolling and forming a lot of materials. Among them, low carbon steel is a material commonly used in rolling forming, and non-ferrous metal is more suitable for roll forming.
- 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.
