Investing in tube
Tube Products of India is a manufacturer
of precision welded tubes.
Part of Tube Investments of India Ltd,
the flagship company of the US$2.4
billion Murugappa Group, the company
started in 1954 as a supplier of bicycle
tubes to TI Cycles.
Operating from four manufacturing
locations in India and one in China,
the company supplies precision
welded tubes for boilers, air heaters,
general engineering and automotive
applications.
The company exports tubes to North
America, Canada, Australia, Europe
and South East Asia, and has a
marketing office in Chicago to facilitate
close proximity to North American
customers.
Tube Products of India’s DOM tubes
range from 10 to 101.6mm outer
diameter, in thicknesses from 0.89 to
5.59mm.
For ERW tubes, outer diameters range
from 15.88 to 127mm, with a thickness
range of 0.7 to 6mm.
Expertise in developing customised
processes for low and medium
carbon steel enables the company to
achieve strength levels of 1,800MPA.
The company’s products are used in
applications such as shock absorbers,
hydraulic cylinders, propeller shafts,
front forks and side impact beams.
The company also supplies value
added tubes and tubular components
to automotive companies in India and
the global market.

Laser welded tubes in stainless steel,
pure nickel and nickel alloys
Le Guellec has specialised in the cold drawing of precision tubes for over 60
years. The company’s versatile production equipment enables it to offer small,
medium and large quantities within a wide size range (from 0.008" to 1" OD and
0.002" to 0.01" wall thickness). The company recently acquired a laser welding
line dedicated to the production of thin and very thin walled small tubes in large
volume.
This machine is able to weld standard alloys such as stainless steel, and also
exotic alloys such as pure nickel and nickel alloys. The welding quality is
continuously controlled throughout production, tracking the welding system
with eddy current testing. Laser welded tubing is cleaner, more concentric and
does not need filler materials. The laser technology helps Le Guellec to obtain
the finished product directly, making the company competitive where large
volumes are involved.
Due to this high volume capacity, the laser welding line can be very reactive and
can adjust to requirements. Tubes are manufactured in continuous coils, but
on request can also be delivered in straight lengths. The equipment obtained
the accreditation of the aeronautics industry for the supply of heat exchanger
tubes. It can also incorporate other elements into the tubing during processing,
such as plastic jacket, wire, other tube alloys and other materials (ie composite
tubes). For very thin wall small tubes running in large volumes, the laser welding
solution is a top choice among design engineers.
