Abstract
An apparatus and method for protecting an inner radial surface of a radial member of a turbomachine from corrosion are provided. The method may include shaping the inner radial surface of the radial member and a corresponding outer radial surface of a corrosion-resistant liner. The method may also include heating the radial member to increase a diameter of the inner radial surface of the radial member, and inserting at least a portion of the corrosion-resistant liner into the radial member. The method may further include attaching the corrosion-resistant liner to the inner radial surface of the radial member to thereby protect the inner radial surface of the radial member of the turbomachine from corrosion.
Claims20
An apparatus for processing corrosive fluid, comprising:
- a housing defining a tapered bore having a decreasing inner diameter;
- a corrosion-resistant liner having a tapered exterior surface defining a corresponding decreasing outer diameter;
- and
- an interface defined between the corrosion-resistant liner and the housing, the interface being substantially free from welded material and configured to provide a bond between the corrosion-resistant liner and the housing.
A method for protecting an inner radial surface of a radial member of a turbomachine from corrosion, comprising:
- shaping the inner radial surface of the radial member and a corresponding outer radial surface of a corrosion-resistant liner;
- heating the radial member to increase a diameter of the inner radial surface of the radial member;
- inserting at least a portion of the corrosion-resistant liner into the radial member;
- and
- attaching the corrosion-resistant liner to the inner radial surface of the radial member to thereby protect the inner radial surface of the radial member of the turbomachine from corrosion.
