Slitting

HR Coils are slitted to predetermined widths for each size of pipes.

Uncoiling, End Shearing And Welding

Slitted coil is uncoiled at the entry of ERW mill and the ends are sheared and welded one after another to make it a single endless strip.

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

Welding
The open edges are heated to the forging temperature through high frequency low voltage high current and press welded by forge rolls making perfect and strong but weld without filler materials.

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

Seam Annealing
Whenever required, welding portion and heat affected zone is put to normalising and then cooled down in air cooling bed

Sizing
After water quenching, slight reduction is applied to pipes with sizing rolls to give them desired accurate outside diameter.

Cutting
Pipes are cut to required lengths by C. O. C. cutting machine to get the perfect cutting.

End Facing And Bevelling
The pipes 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.
