Roll form tooling for tube production. In the range of tube production we develop forming strategies for: - seam welded tube profiles - folded tube profiles (B-type, multi-port) - multi-part tube profiles, with or without inner fin - special profiles
The drawing process also functions to homogenize the weld zone into the base metal and improve the cosmetic appearance of the tube. The drawing compound is a breakthrough, trade protected oil formula that cleans easily. Teflon® is never used. The concentricity of ATT's welded and drawn tubing is greater than possible from many seamless processes.
Nov 27, 2019· A seamless tube, also known as a seamless pipe, is a tube/pipe with no welding seam. It is made of a single piece of metal without any joins. Each end of this tube is connected to another tube without any welding joint. The ends have threads that help in forming a connection with other tubes.
Aug 16, 2001· 6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition. Operators must know how much life is left in the tooling before the next scheduled rework.
The proper welding section set-up and arrangement in relation to induction welding are important to ensure effective and efficient welding operation. Squeeze roll diameter, seam guide, welding coil, impeder and impeder cooling affects the rapid heating of the strip edge to be welded, specifically critical for small tube induction welding below ...

Tube forming pattern design.
The strips pass through the number of rollers as per the required size. In the tubes mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip welding process. In this way, rolled pipes and tubes are formed. The cleaning and heating phase Welded Tube Mill Line
Rollforming Equipment. Rafter has an exclusive strategic partnership with Camasi Máquinas e Equipamentos to expand its offering of advanced rollforming equipment in North America. This enables us to offer end-to-end, turn key solutions to more customers in the growing rollforming market.
Butt-welded pipe is produced by hot forming after the whole material has been heated, and seams are then butt welded. This type of pipe is hot-dip galvanized and used for carrying water and gas. The outer diameter of ERW pipe and butt-welded pipe is determined by the width of the material coil.
First to apply induction welding to the production of welded seam tube and pipe. First to manufacture rafted roll formers and tube mills. Introduced the multiple cross-type tube welding transformer, a breakthrough in tube mill production speeds. First 180- and 360-cycle tube welder for improved weld .
Welded Tube and Pipe. Ever since it became possible to manufacture strip and plate, people have constantly tried to bend the material and connect its edges in order to manufacture tube and pipe. This led to the development of the oldest welding process, that of forge-welding.
Nov 29, 2018· The spiral steel mill feeds the strip into the welded pipe unit. After rolling through multiple rolls, the strip is gradually rolled up to form a circular tube blank with an open gap. The reduction of the pressing roll is adjusted to control the weld gap to 1. ~3mm and make the solder joints flush at both ends.
Mar 02, 2019· Typically with either a round tube or pipe, the weld seam will be located on the neutral axis, which is the centerline radius of the bend. But if requested, the seam can be put in other locations. Often with square or rectangular members the weld seam will be placed where it is most aesthetically pleasing to the customer after rolling.
