Abstract
Official abstract text for this publication.
A pipe or fitting having a polymer liner and a replaceable component including an outer ring having an outside diameter matching the inside diameter of the pipe or fitting, a polymer liner bonded to the outer ring and having an inside diameter matching the inside diameter of the liner of the pipe or fitting. The replaceable component is disposed in an inlet or outlet of the pipe or fitting so as to form a continuous bore lined with a polymer.
First claim
Opening claim text (preview).
What is claimed is: 1. A polymer-lined pipe or fitting having an end configured to receive a replaceable component to form a continuous bore, the end comprising a mechanical coupling for attaching and detaching another pipe or fitting, the replaceable component comprising: (a) an outer ring having at least a portion having an outside diameter matching an inside diameter of the pipe or fitting, wherein the outer ring comprises two or more rings, separated by the polymer liner; and (b) a polymer liner bonded to or encapsulating the outer ring and having an inside diameter matching the inside diameter of the polymer liner of the pipe or fitting. 2. The pipe or fitting of claim 1 wherein a first ring has an outside diameter matching the inside diameter of the pipe or fitting and a second ring has a smaller diameter which does not contact an inside surface of the pipe or fitting. 3. The pipe or fitting of claim 1 wherein the polymer liner forms a lip at the second end, where the lip is in contact with the inside surface of the pipe. 4. The pipe or fitting of claim 3 wherein an end ring is embedded inside the lip. 5. A polymer-lined pipe or fitting having an end configured to receive a replaceable component to form a continuous bore, the end comprising a mechanical coupling for attaching and detaching another pipe or fitting, the replaceable component comprising: (a) an outer ring having at least a portion having an outside diameter matching an inside diameter of the pipe or fitting, wherein the outer ring is elongated and tapered to be a portion of a truncated cone, wherein a first end of the outer ring contacts an inside surface of the pipe and a second end does not; and (b) a polymer liner bonded to or encapsulating the outer ring and having an inside diameter matching the inside diameter of the polymer liner of the pipe or fitting.
