Abstract
A corrosion-resistant component is provided for a corrosion-resistant tube assembly. The component includes a corrosion-susceptible metal tube and a sleeve of corrosion-resistant metal mechanically joined to the tube for protecting the end portions of the tube. The sleeve includes a first portion terminating in a ring-shaped second portion. The first portion annularly extends about a surface of a tube and is mechanically joined thereto. A second portion of the sleeve overlies the annular end surfaces of the corrosion-susceptible tube. The component includes a corrosion-resistant liner for the tube which is sealed with an inside surface of a portion of the sleeve about the circumference by an expansion joint between the liner and tube. A corrosion-resistant tube assembly having a corrosion-resistant component is also provided such that tubes are mechanically and threadably joined by the sleeves. The assembly has all inside surfaces of the tube assembly of corrosion-resistant material. An annular notch may be provided in the sleeve or tubing or both to receive the sealing and expansion ring.
