Tubeweld (India) Limited is one of the leading manufacturer and exporters of seamless carbon/alloy steel pipes and tubes, ERW boiler tubes, Air Pre-heater tubes including Carbon steel tubes, Steam pipes and fittings, Boiler components like Superheater coils, Economiser coils, Steam generating bent to shape tubes, panels, heaters, pipework for steam, feed waterline etc. We are a group of forty companies, having well diversified business. Our core competency lies in the manufacturing of boiler components and spares for very large fossil fuel fired steam boilers in thermal power plants, sugar & fertilizer industries, refineries, petrochemical, steel industries, smelter waste heat boiler, fluidised bed boilers etc.. SAW Tubes
The electrodes are not in actual contact
with the pipe. The current passes from on electrode through a granular
flux and across the gap in the pipe to the second electrode. The high
temperature of the arc heats the edges of the plate, a welding rod
placed just over the seam is thereby melted and metal is deposited in
the groove. After the outside weld has been made, the pipe is conveyed
to an inside welder where a similar operation is carried on, except that
no backup shoe is need. This process is used for pipes from 24" to 36"
i.e 610mm to 914mm OD. Flat plate is first pressed into U and later O
shape. The O shape is placed in an automatic welder and backed up on the
inside by a water cooled copper shoe. Two electrodes in close proximity
and used. |
