With the continuous growth of China’s electronics industry, chips, liquid crystal displays and other product markets, the role of clean application materials as the front end of the industrial chain cannot be ignored. As an important part of clean materials, stainless steel electropolished (EP) tubes are in increasing demand.

The research and development of biotech drugs in China started relatively late, but with the strong support of the national industrial policy, the field has developed rapidly, gradually narrowing the gap with advanced countries, and even taking the lead in some specific projects in the world. With the development of biopharmaceutical technology, the requirements for various supporting equipment and facilities including stainless steel clean tubes are also increasing.

Advanced medical, laboratory and other fields put forward higher and higher requirements for the purity of various gases, and then put forward higher and higher requirements for gas transmission pipelines, and general-purpose BA pipes can no longer meet their needs. The electro polishing process has already matured, but there are still very few factories in China that can provide electropolishing on the inner wall of slender pipes and reach a high level.
