These tubes go through various processes such as annealing, pickling, passivation, hydro testing, polishing, inspection and marking. Our range is then packed and dispatched safely to the clients.
Annealing
The process of annealing or heat treatment on tubes is carried out in fully automated conveyor. The process includes the heating up of tubes at a specified temperature and then quenched it immediately in the circulating water.

Straightening
After the process of annealing the tubes are set to be straightened with the help of straightening machine. Further, to provide high degree of straightness, the tubes can also be rounded up during the operation.

Polishing
After the process of straightening, the tubes are polished to provide them a highly aesthetic & hygienic value, low maintenance and high durability. These polished tubes are highly demanded in the architecture, general engineering and dairy & food processing sectors.
