For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly.
The copper disk electrodes make contact on each side of the seam and temperature is raised to the welding point. Outside flash is removed by a cutting tool as the tube leaves the electrodes, inside flash is removed either by an air hammer or by passing a mandnel through the welded tube after the tube has been cooled. This is termed as Electric Resistance welded or ERW tube/pipe. If this ERW is being drawn further to get desired size of tubes or pipes, in cold condition is called as Cold Drawn welded or CDW.
All power devices operate at high efficiencies required quality steel tubes, to guarantee their safe and long term operation. These Tubes are called as Boiler Tubes
Boiler Tubes are specially manufactured to withstand high pressure and temperature. Boiler tubes are used in energy type equipments like steam pipeline, boilers, super heaters etc.
Boiler tubing is used in these industries:
- Steam Boilers
- Fossil Fuel Plants
- Heat Exchangers
- Electric Power Plants
- Cogeneration Facilities
- Air Preheater Unit
- Waste Heat Plants
- Power Generation
- Economiser etc
