Black ERW Pipes
plant employs HF frequency welding process for manufacturing pipes, using
the finest virgin steel from renowned steel plants in India like JSW, ISPAT,
ESSAR and SAIL.
In HF process pipes are welded with Radio Frequency
Induction Tube Welder of 200 KW, which Weld at high speed with superior
finish. The process begins with Cold Stamping of Lakshmi Cauvery Seal of
The tubes then progressively form as the strip passes
through successive rolls and is followed by high frequency induction welding
at the edges to complete the weld. Subsequently the welded tube under goes
further processes to ensure superior finish and strong weld. Tubes that pass
all quality parameters undergo end-facing operations to ensure smooth &
clean edges. Final quality checks and finishing operations are performed
Galvanized ERW Pipes
process starts by dipping the Black ERW Pipe in Hydro Chloric acid to get
rid of debris and any foreign substance that might have gathered on the
pipe. The pipes are then cleaned by water and dipped again in a mixture of
ammonium chloride and Zinc Chloride (Flux) to improve the bind between steel
and zinc coating.
The pipes are now dipped in high-grade molten
zinc and special care is taken that the zinc tank is at an apt temperature
to ensure superior finish and consistent zinc coating on pipes. Pipes are
then introduced to pressurized steam to remove any excess zinc that might
have deposited on the surface of the pipe. Pipes are then cleaned and sent
for finishing / quality processes.
