Electric Resistance Welded Tubes

Electronic automated arc spray equipment of all metal wires - electronic control and management

The welding process is one of the core ways in which we manufacture precision tubes. Our high-quality tubing starts off as a flat strip of metal. The strip is formed into a tube through a series of rollers and the join, also called the seam, is then welded together. Welded Processes Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing - are used to ensure a consistent weld. Just like with seamless manufacturing, welded tubes can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of coiled tube, these can also be measured during coiling using a laser measurement. The main welded tube manufacturing processes used are strip welding and cold drawing, but other important processes in between, or at the end of the drawing process, include Please note that we have a minimum order value of £10,000.

With tube-to-tubesheet weld heads, it is possible to achieve consistently high-quality, reproducible welding of tubes to tubesheets, with or without additional wire. The tubes to be welded can be flush with the tubesheet, offset, protruding or behind the tubesheet. The RBK 38 S and the RBK 60 S are our two new tube-to-tubesheet weld heads. The RBK 38 S is a small, handy water-cooled head for welding tubes to tubesheets up to an ID of 36.7 mm, without additional wire. Package includes: — Weld head — Water-cooled hose package, 6 m — Pull bar B — Gas hood ID 35 mm — 0° electrode holder — Transport case Optional: — Div. electrode holders for RBK 38 S — Div. gas hoods for RBK 38 S — Div. spring sleeves and pull bar sets for RBK 38 S

The RBK 60 S is an extremely robust water-cooled weld head for a standard heat exchanger application up to an ID of 60 mm, modified to an ID of 99 mm or 120 mm. The head is pneumatically centred and is available with a rotating wire device and/ or arc voltage control (AVC) as an option. The head can also be used with a pneumatic positioner instead of a balancer. Versions: — RBK 60 S weld head with pneumatic centring, including hose package, 8m, water-cooled — RBK 60 S weld head with pneumatic centring and wire feeder incl. hose package, 8m, water-cooled — RBK 60 S weld head with pneumatic centring, wire feeder and AVC incl. hose package, 8m, water-cooled Package includes: — Weld head — Small torch incl. torch consumables and tungsten electrode Ø 2.4 mm — Water-cooled hose package, 8 m — Pull bar B — Transport case Optional: — Div. spring sleeves and pull bar sets for RBK 60 S — Torches, Balancer, Tube-to-tubesheet positioner...

Metal In put into operation a machine for laser cutting of pipes with automatic loading and unloading. The size of the treated pipes is: Round pipes: 120 mm Rectangular tubes: 100x100mm The maximum length of the workplace is 6500mm. The machine is equipped with excellent software that allows different shapes in tubes for subsequent assembly and welding. Also, pipes can be cut so that one wall remains uncut, allowing it to bend easily and accurately and find a frame.

The round tubes are manufactured from a coil that is bent and electric resistance welded (ERW). The forming process can be according to EN 10210, which foresees hot forming or cold forming followed by heat treatment, or according to EN 10219, which foresees cold forming without following heat treatments. The finished product is fully killed and welding seam bead is inside and outside trimmed. These products are used to manufacture both welded and bolted structures, in the field of constructions, engineering, industrial constructions, transports, automotive, agricultural machinery and earth moving machinery. The cold finished tubes are particularly suitable for structures at sight or for aesthetical uses, thanks to the surface aspect typical of cold forming.
