      1. product introduction
      Titanium three links mainly use titanium materials to oxidize thin films in strong corrosive environment. It has good stability and self passivation ability. This characteristic is resistant to severe corrosion under various severe conditions.

      Whether the titanium three is able to resist the corrosion of the working environment medium is the key to the chemical stability of the "blunt oxide film" on the surface in the corrosive medium. For neutral, oxidizing, and weakly reductive media, the "blunt oxide film" itself has a good stability. For reducing the corrosive medium high temperature or low pH value, to improve the stability of the passive oxide film ", through the addition of inhibitors (such as air, water, heavy metal ions and anions), as modified by titanium ion treatment, anodizing method to improve titanium in reduction in the medium of corrosion resistance and surface hardness to meet the requirements

      2. product specifications
      The end of the three - way nozzle with equal diameter of A. is the same size.
      The three - way three - way pipe is of the same size, and the pipe size is less than that of the pipe.

      3. material
      The common material TA1 (Gr1), TA2 (Gr2), TC4 (Gr5), the customer needs other materials can also be customized.

      4. performance standards
      The chemical composition accords with the standard of GB/T 3625-2007.
