» 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 and inside (if needed) is trimmed out through carbide tools.

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

» Sizling
   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 flying cut off disc/saw cutter.

» 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.
