B.A （bright annealed）Stainless tubes are mainly used for super clean gas pipe line. And surface roughness, dimension tolerance and mechanical properties are controlled by cold working process, with high corrosive resistant properties.
Dextube clean BA tubes are manufactured by our special production process.
