光亮退火不锈钢无缝管 BA管 洁净管

不锈钢厂家

  光亮退火不锈钢管主要用于洁净管道，其表面粗糙度、尺寸公差和机械性能由冷加工工艺控制，具有更好的耐腐蚀性。我司BA管采用我司独特的生产工艺制造，具有优异的性能。

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.
