Annealing
After the goods are cold drawn to sizes, the tubes are put on annealing furnace for heat treatment and normalising.
Straightening
Post annealing, the goods are passed through a seven roller straightening machine to achieve proper straightening of the tubes.
Eddy current
Post straightening, each tube is passed through eddy current machine to detect for surface cracks and other defects . Only the tubes that pass eddy current are fit for delivery to customers.
