TUBE MANUFACTURE Tube manufacture is largely confined to commercially pure titanium Tube manufacture is largely confined to commercially pure titanium Seamless tubes are manufactured by hot extrusion followed by cold pilgering Seamless tubes are manufactured by hot extrusion followed by cold pilgering Seam welded tubes are used extensively in heat exchangers in power plants, desalination of sea water, ship building etc.The starting material is cold rolled and slit to width strip, mm in thickness depending on application. High demands are placed on dimensional and surface quality aspects of the strip Seam welded tubes are used extensively in heat exchangers in power plants, desalination of sea water, ship building etc.The starting material is cold rolled and slit to width strip, mm in thickness depending on application. High demands are placed on dimensional and surface quality aspects of the strip The tubes are manufactured in 15-30mm Φ range The tubes are manufactured in 15-30mm Φ range
