        2、內表面電化拋光,粗糙度Ra 0.2m~Ra 0.4m,與管板氬弧焊接,焊口進行拋光處理。
        Double plate heat exchanger has many merits, such as reliable and simple structure, strong adaptability, convenient cleanout, large processing
        quantity, bear high temperature and pressure, etc. There's no dead angle and pollution in the facility. it's easy to clean, Occupied area is small
        and it is easy to install. It is a standardized heat exchanging facillity and technology is ripe. It conforms to GMP demand of medical industry and
        is also an ideal heat exchanging facility in medical industry.
