  The process utilizes the latest technology and modern equipments for producing ERW Pipes.

1. Slit preparations: HR Coils are slitted to predetermined widths for each size of pipe and thickness. Slitted coil is uncoiled at the entry of mill and the ends are sheared and welded one after another to make it single endless strip.

2. Forming: Slitted coils are initially formed into U shape and then into a cylindrical shape with open edges using a series of forming rolls.

3. Welding: The open edges are heated to the required temperature through high frequency induction current and press welded by forge rolls making perfect and strong butt weld without filler meterials.

4. Debeading: Weld flash on top is trimmed out through carbide tools.

5. Seam Annealing: Whenever required, welding portion and heat affected zone is cooled down in air cooling bed.

6. Sizing & Cutting: After water quenching, slight reduction is applied to pipes with sizing rolls to give them desired accurate outside diameter. Pipes are cut to required lengths by flying cut off disc/saw cutter.

7. Facing and Bevelling: The pipe ends are faced and bevelled by the end facer. All the processes are continuous with auto arrangements. These plain ended tubes go for further processing as per the customer need like galvanizing, threading, black varnishing etc.

8. Packing: Finishing pipes are bundled in desired number of pieces as per customer's requirement and packed properly to ensure freshness till delivery.
