Tubes SBU of Tata Steel came into being in 1985,

after the merger of the erstwhile Indian Tube

Company with Tata Steel. Tubes SBU

manufactures commercial and precision tubes at

its two plants, namely, the Standard Tubes Plant

and the Precision Tubes Plant.

Tubes Strategic Business Unit of Tata Steel is the

largest manufacturer of a variety of steel tubes in

India with an annual production capacity of around

4,00,000 tonnes and major expansion plans to

manufacture higher sizes. The SBU has its plants

situated in Jamshedpur with a network of sales

offices across the country and its marketing

headquarters in Kolkata to provide better

customer service.

Production of Tata Structura Steel Hollow Section

begins with the setting of wide Steel Hot Rolled

Coils to the width required for production of

customer specific section dimensions. This slit coil

is then fed through the mill and is shaped into a

round tube by a series of forming rolls.

The converging strip edges of this round tube are

squeezed together and welded using high

frequency induction welding. Immediately after

this, the external excess weld bead is removed.

The tube then passes through a set of shaping

rolls where it is shaped to its final form of either

square, rectangle or circular and is exactly sized

to the required dimensions.

Cutting to the required length and bundling are the

final steps in this fully automatic process.

Presently Tata Structura Rectangular & Square

Steel Hollow Sections can be supplied to IS:4923

Grade Y 310 upto a maximum of

250 x 250 mm for square sections and

300 x 200 mm for rectangular sections. Circular

Sections can be supplied to IS:1161

upto a maximum NB of 300 mm.

However, with expansion plans, Tata Steel will be

able to augment the size range for

all sections.

Tata Structura : the winning edge

Besides bearing the trust and value of the Tata

Steel brand name, Tata Structura Steel Hollow

sections are advantageous from techno-economic

aspects as well.

The raw material used in manufacture comes from

the Tata Steel's world-class Hot Strip Mill.

The excellent distribution of material around the

axes of these steel hollow sections accounts for

unbeatable strength and other application

advantages. Unique features like high torsional

rigidity and compressive strength adds to better

efficiency than conventional sections. Higher

strength to weight ratio in these sections could

result in upto 30% savings in steel. Moreover, dust

accumulation is minimised due to smoothness and

uniformity of finishing.

Last but not the least, Tata Structura Steel Hollow

Sections enhance the aesthetic quotient of any

construction, thus adding to the appeal.

In the recent 3.0 MT expansion project at

Jamshedpur, renowned consultants

and have

extensively used Tata Structura for Conveyor

Structures, Plant Building, Pipe Line Supporting

Structures and Warehouses etc.

Conveyor Structures

Design of these structures with Tata Structura

proved to be more economical as the truss and

the girders are lattice construction and

compression is the governing criteria. Use of

gusset plate is minimum which adds aesthetics

to the overall structures.

Mass volume of material handling accounts for a

large percentage in the steel industry. According to

the flow of production the conveyor system

is used for :

Supporting Structures for Utility Pipe Lines

at 'I' Blast Furnace Diversion

Tata Structura sections were used for the 'I' blast furnace diversion. The

furnace, with a hot metal capacity of 3.05 MTPA was part of the brownfield

expansion in Jharkhand. The supporting structures for the diversion consist

entirely of Tata Structura pipes with a bridge span of 36.5 m.

Overhead Cable Gallery

The overhead cable gallery serves as the power distribution system from

MPDS-4 to MPDS-7 of the 'I' blast furnace 3.05 mt expansion project.

The entire length of the 29m span cable gallery was designed with Tata

Structura sections.

Foot OverbridgeOn railway track inside the steel plant

The foot overbridge, 4.0 meter wide and spanning 35 meter, has

eased the safe movement of 10000 workers who cross the most

hazardous rail tracks near the East Plant Drop Gate (EPDG) daily. At

Jamshedpur steel plant, Tata Structura has proved yet again that its

blend of aesthetics, weight to strength ratio and safety is much

superior to conventional structures. Total consumption of steel with

major usage of Tata Structura is approximately 250 mt (30% less

than conventional structural design) and has led to huge savings in

the project cost.
