In many instances, hydro
power plants are located
in areas where access
is difficult. Well-considered
solutions and special
equipment designed by
our engineers help to
mask even the most challenging
situations. Specially
designed temporary erection
structures are among these
not-quite-so-usual methods,
as well as use of all
terrain cranes for erection
method or mobile ropeway
systems for erections
in extreme steep terrain. |

Research
and development was always
a driving factor also
in penstock construction.
Hydraulically optimized
design for bifurcations
and manifold systems,
as well as development
in fabrication technologies
have secured our lead
in this field. |

Depending
on the actual project
settings, GMW designs,
manufactures, and
installs pressure
conduits both as
exposed and embedded
penstock. These
equipment are designed
as per various international
standards for specific
project requirements,
and high quality
norms. |

We today have capacity
to handle thickness
up 50mm and our
technicians have
masterminded welding
of special steel
requiring rigorous
quality control.
All our welding
procedures and welders
are qualified according
to ASME Pressure
Vessel Code. For
work shop fabricated
pieces use of fully
automated SMAW is
done to enhance
quality and productivity.

The
companies engineering experts
ensure high quality of welding
by inspecting every weld
by dye-penetration check,
ultra Sonic testing and
radiography. Each of the
pipe pieces is then subjected
to hydrostatic test before
painting to ensure pipes
are safe and strong to withstand
water pressure. |
| The
coating and anticorrosion
protection of pipes, penstock
and accessories conform
to specific customer requirements
and high quality standards. |

Hydraucally
optimized designs for
bifurcation, trifurcations,
and manifolds systems,
as well as our unmatched
experience in fabrication,
welding technology and
non destructive techniques
for maintaining quality.
