They are called CEW Tubes or CDW Tubes. These tubes are widely used in automobile industry and also for manufacturing material handling equipment, special purpose machines, hydraulic equipment, textile machinery, etc. Just like Seamless Precision Tubes, they too have low carbon content, are highly malleable, suitable for bending. The tubes are annealed, if required, after drawing, straightened and undergo a pickling process that gives it an excellent blemish-free finish. Finally they are tested chemically, physically and for hydraulic pressure and other non-destructive tests such as Eddy Current Test, etc. and suitably packed in wooden boxes before shipment.EN 10305-2 and DIN 2393 Grade ComparisonDIN Norms: DIN 2393EN Norms: EN 10305-2UNI Norms: UNI 7946RSt 34.2E195Fe320RSt 37.2E235Fe360St 52.3E355Fe490Nominal Size: 20, 22, 25, 26, 28, 30, 32, 35, 38, 40, 42, 45, 48, 50, 55 mmWall Thickness: 1; 1,2; 1,5; 1,8; 2; 2,2; 2,5 mmTolerances:Nominal SizeNS 20 -
