      1. product introduction
      Titanium flanges are made of nonferrous metal titanium or titanium alloy to make pipes and tubes connected to each other, connected to the tube end.
      There are holes in the titanium flange, and the bolts make the two flanges tightly connected. The flange is sealed with a cushion. A flange pipe refers to a pipe with a flange (a flange or a joint).
      It can be made up of threaded connection or welding. The flange is composed of a pair of flanges, a gasket and a number of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection.
      According to the structure type, it has the whole titanium flange, the welding titanium flange, the live titanium flange and the threaded titanium flange.

      2. product specifications
      Surface: Forged surface, rolling surface, light surface, polished surface
      Specifications: according to the standard of flange production of various specifications, and can also be provided by the customer drawings to produce the designated non - standard flange.
