The Electropolished Stainless Steel Tubes
The electropolishing(EP), a type of surface treatment on stainless steel tubes, is a great technique to help our daily life.
In the pan-semiconductor manufacturing industry (integrated circuits, photovoltaic cells, flat panel display, etc.), electropolished stainless steel tube is used for transport of high purity process gas. The inner roughness of stainless steel tube can be controlled to 0.1 μm for semiconductor industry.
In biopharmaceutical manufacturing (vaccines, blood products, monoclonal antibodies, etc.), it is used for transport of high purity materials and water for injection.
The core performance of EP pipe:
1. Meet the requirement of SEMI F19/F20 international standard
2. Clean, smooth inner surface with extremely low number of microscopic defects
3. Closed inner surface with chrome-rich oxide layer provides excellent corrosion resistance with very low impurity gas precipitation
4. High precision dimension control and alloy composition control
As the supplier of EP service for several international top pharmaceutical pipeline companies, the pipeline products produced by our suppliers have been widely used in many domestic and foreign biopharmaceutical factories such as vaccine and blood products, including wuhan Institute of Biological Products and Beijing Institute of Biological Products, the base of COVID-19 vaccine. Our production capacity is fully supplying the first line of COVID-19 vaccine manufacturing.
