Stainless Steel - Clean BA/EP Tubes

Clean tubes feature a smooth surface, ultra-high purity, high-precision tolerances, excellent inner surface roughness, with an inner surface Ra of less than 0.4 μm. They are primarily used in industries with high cleanliness requirements, such as semiconductors, medical catheters, food and beverage processing, pharmaceuticals, superheater heat exchangers, high-purity gas and fluid piping systems, among others. These tubes are manufactured in accordance with ASTM A269/A270 standards. For environments demanding utmost cleanliness, the tubes undergo nitrogen purging and packaging in clean-rooms to meet these stringent requirements. The inner surfaces of the tubes can be supplied in a bright annealed (BA) or electro-polished (EP) finish.
