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.
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.
Sep 12, 2016· The tube is formed by moving the cut coil through a series of rollers, and the seam of the tube is then welded in a chemically neutral environment. A rolling application is used to forge the welded seam, and a heat treating process is used to finish the welded tube.
76 Tube Mill Line manufacturers High frequency welded tube mill line is designed to produce tubes.This line utilizes roll forming to process steel strip into various shapes.Using high frequency induction heating,this line is capable of producing section material of various diameters and sizes by squeezing weld seam together int...
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

Formtek & Yoder have long been recognized as one of the earlier pioneers in the welded seam tube mill business. Yoder offers multiple standard tube mills for common product sizes. In addition to the standard machines, Yoder also offers specialized equipment that covers a huge diameter range of metal tubes and pipes; from the 3/16″ (4.76mm) O ...
The tube separates during the process and is formed back together by an inherent welding process while passing through the extrusion die. There is a slightly visible seam that may be noticeable to the naked eye if the tube is anodized or "finished." Advantages of structural tube and pipe: Improved control of wall thickness eccentricity
May 27, 2015· In this process, long sheet steel is rolled into a cylinder and welded along the edges. This is followed by heat treatment and being furnished with a threaded connection. voestalpine Tubulars & Co KG focuses on seamless tubes, which have the decisive advantage of having no welded seam, since welded seams are a sensitive area.
Φ38 Tube mil lLine. High‐frequency welded tube mill line is designed to produce round tube diameter of 10.0 – 38.1mm, and wall thickness of 0.4 ‐1.8mm.This line utilizes roll forming to process .
By: John Wright, Electronic Heating Equipment, Inc. USA John Wright's 30-year career in high frequency tube welding has spanned South Africa, the United Kingdom, and for the last 22 years the United States. He founded Electronic Heating Equipment in Buckley, Washington, in 1980. The company manufactures impeders & work coils for induction tube welding, & provides technical support for all ...
The process of welding tube and pipe requires several variables to be in check for efficient stable production. The material type, gauge, edge condition, tooling setup, and weld heat are just a few of the factors that quality control managers, mill supervisors, and operators must pay attention to in their efforts to achieve output and ...
Jan 01, 2013· The seam is measured and inspected e.g. regarding holes immediately after the welding process. As in many tube mills the seam is grinded inside the machine, a later seam measurement is not possible any more. Full quality control and data traceability is frequently demanded.
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.
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.
With RHF seam welded tube machines, made by Schöler, you definitely will be. ... Production of longitudinal-welded tubes by high-frequency welding process Radiator, CAC, oil cooler and collector tube applications flat-oval, hourglass, rectangular or round tube profiles. ... Tube forming pattern design.
Tubes up to 500 millimetres in diameter with walls 10 millimetres thick are produced on ERW lines. Larger-diameter pipes are often produced by forming the strip into an endless spiral, as shown schematically in B in the figure.Forming is followed by continuous welding of the seam, often by automatic arc welding.Pipes up to 1.5 metres in diameter and with a 12-millimetre wall thickness are ...
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 .
Seamless tubes are as defined – they do not have a welded seam. The tubing is manufactured through an extrusion process where the tube is drawn from a solid stainless steel billet and extruded into a hollow form. The billets are first heated and then formed into oblong circular molds that are hollowed in a piercing mill.
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.
