Tubes products are manufactured through different production Steps. Steel coils are slitted to the required widths and formed to the required shapes and welded by using electrical resistance welding technique in the tube mill. Tubes are first formed as round shapes when flat steel strip passes through a series of rolls and welded by high frequency welding system. Round shapes pass through another series of rolls to calibrate the roundness of the round tube or formed to a square or rectangular shape. Continuously welded tubes are cut to required lengths by a precise flying saw cut off machine operated by a digital drive system for high accuracy. Tubes are inspected on line before entering into automatic packaging system.
