Specifications

HG114 Hf Straight-seam Weld Pipe Mill is used to produce round pipe 1 1/2" - 4" and square tube 40x40mm - 90x90mm.

HG114 Hf Straight-seam Weld Pipe Mill

I. Summary

The mill is intended for manufacturing round pipe of Φ50mm-Φ114mm with thickness of 1.5mm–5.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.

Finished product will be of round, square or rectangular pipe.

The manufacturing process provides for the uses of coiled strip precut in required width sizes in slitting machine.

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:Improvement in rolling forming process: It is difficult to control the rolling process and can cause waste easily.

Q:What is the surface rolling forming machine process?: The rolling process using metal at room temperature, cold plastic characteristic, through the rolling tool is the rolling tool to put some pressure on the metal surface, so that the workpiece surface by plastic deformation, the height to the lower tissue slip, the surface roughness decreased.

Q:Introduction of roll forming process: Roll forming began around 1960s in europe. Because of roll forming, the working model has the advantages of high production efficiency, saving material and increasing product strength.

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?: Maybe there is something wrong with that roller. It rolls out of the wrong angle and the size will be out of order.

Q:Process mould for rolling forming process: A movable wire plate, made of the same fixed wire plate, for relative reciprocating motion. Roll forming is the design of different structures on the plate rolling on the workpiece. Roll out all kinds of thread, convex ring, knurling, end chamfering, groove with different width and thickness as well as other required shapes.

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: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.
