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: 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
- The rolling will produce a hardening layer on the surface of the workpiece. This layer has obvious delamination phenomenon with the internal material, which is easy to cause the surface layer to fall off;
- 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: 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: What is the surface rolling forming machine process?
- Different from cutting, mirror rolling is a kind of plastic processing. Not only is the rolling workpiece surface roughness moment can reach Ry0.1-0.8 m, and the wear resistance of the surface hardening process has been improved at the same time fatigue strength also increased 30% advantages in cutting can not get.
- 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
- Rolling molding is usually through upsetting a blank cold heading machine, thread rolling machine rolling after processed. The equipment for thread rolling and rolling forming includes various reciprocating flat rolling machines, planetary wire rolling machines, two cylindrical roller spinning machines and three cylindrical roller spinning machines.
