Conveyance Tubes > Idler Tubes

Manufacturing Process

Tata Pipes-Idler Tubes production process begins with slitting of wide Steel Hot Rolled Coils to the width required for the production of customer specific section dimensions. The slit coil is then fed through the mill and is shaped into a round tube by a series of forming coils. The converging strip edges of this round tube are squeezed together and welded using high frequency induction welding. After this the external excess weld bead is removed and the tube then passes through a set of shaping rolls where it is shaped to its final form, exactly sized to the required dimensions followed by cutting to the desired length and bundling in a fully automatic process.

Quality Control

The quality of our product is controlled during the manufacturing process. It starts with slitting the strip edges, continues with speed and temperature control during the HFIW process and is followed by non-destructive eddy current testing directly after welding. Off-line drift and flattening tests are conducted after this – all as per ISO 9000:2002 quality management system.

Idlers for Belt Conveyors

Steel tubes are extensively used as idlers for belt conveyors. The tubes are made from the steel manufactured by Open Hearth basic oxygen, Electric Furnace or combination of these processes. These tubes are manufactured by one of the processes - Seamless or ERW (Including HFIW). The height of the internal fin of the ERW pipes should not exceed 1.7mm. The maximum Phosphorus and Sulphur contents are limited to 0.005%.

Conveyance Tubes > Cold storage -----------------

Cold storage plants are large warehouses equipped with a vapour compression system for refrigeration, traditionally using ammonia as the refrigerant. The system functions through a network consisting of a compressor, condenser, expansion valve and an evaporator (referred to as bunker coils when placed in a bunker). A brief description of the refrigeration process is outlined in the next few paragraphs.

The compressor sucks in saturated and dry ammonia vapour at design evaporating temperature and pressure and compresses the vapour into a pre-determined higher pressure, called the condensing pressure with corresponding temperature. The actual temperature at the condensing pressure is considerably higher due to superheating it the compression process.
The vapour is then pumped to the condenser pipes, where it is cooled and liquefied using water sprays. The liquefied ammonia at high pressure is collected in a receiver and then pumped under pressure to the expansion valve, where the pressure is reduced by throttling and the low pressure liquid flows to the evaporator or bunker coils located inside the insulated warehouse.

Conveyance Tubes > HVAC ---------------------

The low pressure liquid ammonia inside the bunker coils evaporates into vapour being sucked by the compressor and in the process cools down, absorbing heat from the surroundings, thus lowering the temperature of the store. The evaporator coils are kept flooded with low pressure and low temperature liquid ammonia with the help of an accumulator vessel inside which boiling or evaporation of liquid takes place. The evaporating ammonia is sucked by the compressor and the cycle is established.

HVAC stands for Heating, Ventilation, and Air-Conditioning three closely related fundamental functions with both commercial and residential applications. The concept was coined by Volkart Brothers, being the pioneers in this segment, and was introduced way back in 1950.

The steady growth of the real estate market in India has created opportunities for major developers to promote large format office spaces and associated structures like malls, resorts, hi-tech hospitals, etc. This growth has necessitated in realising the importance of the HVAC and Fire-fighting systems in both residential and commercial structures as a prime essential for safety and health.

HVAC can further be distinguished as two separate segments

• Commercial Cooling - large spaces of hotels, IT parks, malls, airports etc.
• Process Cooling - for sterilized rooms of pharmaceutical and manufacturing industries.
• Pipes used in Fan Coil Unit - 25 NB to 32 NB
• Pipes used from chiller header to AHU (Air Handling Unit) - 50 NB to 150 NB
• Pipes used in chiller branch lines - 150 NB to 250 NB
• Pipes used in chiller main lines - 300 NB to 500 NB

The primary use of HVAC is to regulate room temperature, humidity, and air flow, ensuring that such elements remain within their acceptable ranges. Effective control of such factors minimizes health related risks.

Conveyance Tubes > Plumbing

Galvanised pipes are one of the most important elements in a plumbing set up. The pipes need to satisfy the specific characteristics during their intended usage, particularly with respect to ease of installation, ease of water flow, long term behavior with respect to corrosion resistance and longevity.

Tata Pipes had been a pioneer in the manufacturing of pipes, specifically meant for plumbing applications. To meet the continually increasing demand for quality pipes in the plumbing segment, significant improvements in the quality of pipes have been brought about through innovation in the pipe making and galvanizing process.

With 360 GSM Zinc coating and Boron Steel, Tata Pipes besides being rust free and leak proof have also emerged as the best for our health and safety.
