It is a production process for manufacturing hot finished tubes, pipes, re-draw hollows and
hollow bars in stainless steels and nickel-based alloys.
Range of dimensions:Outside diameters from 42 up to 300 mm (1.65 up to 11.81 inches)
HOT FINISHED TUBES
General Tubes And Pipes
General tubes & pipes are used as piping components and line pipe in a variety of industries
such as the chemical and petrochemical industries,
the oil and gas industries, power generation, processing, in the food and drink industries,
in metallurgy, and many others. In subsea media general
tubes & pipes are be used as line pipe, flowlines, risers, and as hydraulic & gas injection
lines. In topside media general tube & pipe are used as
utility and process piping, sea water piping systems and LNG piping.
Pure nickel UNS N02200 is used in the chemical industry for its corrosion resistance -
particularly to alkalis. It is also used for its properties
in shielding against electromagnetic interference and in transducers.
Hollow bar- also called seamless mechanical tubing- is a tubular product made with
properties and characteristics suitable for subsequent transformation
into numerous cylindrical components and hollow products for different engineering purposes.
Applications for hollow bar include aerospace, electronics,
medical, military, food processing, transportation and the chemical and petrochemical
industry. Hollow bars are widely used in general engineering industry.
Boiler Tubes (Nuclear Industry)
Boiler tubes for nuclear power generation are used within the secondary cycle of nuclear
power stations and form the tube components of a steam generation boiler.
Special safety requirements are required for nuclear boiler tubes, due to their critical
It is the preferred production process for seamless, cold- finished, high alloyed stainless
steel and nickel-based alloy tubes and pipes. This technique
provides a highly efficient, fast production rate, close tolerances and cost-effective,
Range of dimensions: Outside diameters from 6 mm to 244.5 mm ( 0.24” to 9.62”)
Wall thickness from 0.5 mm to 30 mm ( 0.02” to 1.18”)
COLD FINISHED TUBES
Heat-exchanger tubes are designed for heat transfer and mostly used in processes such as
heating, cooling, ventilation, condensation and evaporation
(of liquids, gases, steam and their various combinations). Heat-exchanger tubes are used in
the following equipment: shell & tube heat exchangers, plate &
frame heat exchangers, cooling towers, air coolers and many others. The main industries
using heat-exchanger tubing are chemical & petrochemical, power generation
(including nuclear), oil & gas and others such as the food & beverage industries, pulp &
paper and transportation.
Instrumentation tubes are widely used for hydraulic & pneumatic control systems, fuel supply lines and pressure sensors lines for the transportation industry.
They are also used for onshore control panels, topside processing facilities and subsea manifolds in the oil and gas industry; for high purity tubes in the
semiconductor industry, for advanced engineering fuel rods and control tubes; and for cooling circuits and brake cylinders in the automotive industry.
Boiler tubes are used in thermal power-generation and heating, as components of utility and industrial boilers. Boiler tubes in Power-generation are used only
for utility boilers to generate steam for the production of electricity. Boilers for industrial applications produce steam or hot water for process applications
in a range of sectors such as biomass firing (in fluidized bed boilers), heating, the pulp and paper industry (recovery boilers), in waste to energy plants and
in a number of chemical processes. Boilers are used in all combustion systems (including conventional coal, oil and gas) and are designed to withstand high
pressure and high temperature conditions.
