Process
Heat Treatment is carried out on the continuous roller hearth furnace fitted with temperature controller and recorder. After heat treatment Tubes/Pipes are straightened and subjected to pickling to remove scale on the surfaces. In case the final size cannot be produced from the mill directly, the same is produced by cold drawing operation. To make the tube/pipe suitable for cold drawing, it is coated with oxalate & shop solution which acts as a lubricant and reduces friction while drawing. In the drawing operation, the tube/pipe is drawn over the draw bench using precision tooling i.e. Dies Plugs as per the requirements of finished size. The drawn tube/pipe undergoes heat treatment, pickling and other operations as specified above after surface cleaning.
Finished pipes/tubes are marked with computerized ink Jet Marking Machine. Each pipe/tube is marked as 'Manufacturing Standard'. Grade of Material, Size, Heat No., Stamp of third party inspection agency to Correlate with our Test Certificate. Finished tubes/pipes thus produced undergo various testing and quality checks followed by proper packing and dispatch.
