LINING MEASUREMENT SYSTEM FOR A PIPE OR OTHER FLUID-HANDLING COMPONENT
A fluid-handling component comprises a support element having a surface and an aperture extending through at least a portion of the support element and opening to the surface. The fluid-handling component further comprises a liner disposed on the surface of the support element and having a first liner surface facing away from the surface of the support element. The liner covers the aperture and has a back liner surface facing in a direction away from the first liner surface. A cover member is also secured to the support element and configured to cover the aperture, where the cover member has an inner surface that faces the back liner surface.
1 . A fluid handling component comprising:
a support element having a surface and an aperture extending through at least a portion of the support element and opening to the surface;
a liner disposed on the surface of the support element and having a first liner surface facing away from the surface of the support element, the liner at least covering the aperture and having a back liner surface facing in a direction away from the first liner surface; and
a cover member secured to the support element and covering the aperture, the cover member having an inner surface facing the back liner surface.
2 . The assembly of claim 1 wherein the liner and the cover member have similar sound propagation characteristics.
3 . The assembly of claim 1 wherein the liner and the cover member have operably dissimilar sound propagation characteristics.
4 . The assembly of claim 1 wherein the liner comprises urethane and the cover member comprises plexiglass.
5 . The assembly of claim 1 wherein the support and the cover member threadably mate with each other.
6 . The assembly of claim 1 wherein the support element comprises a support collar having a bore, the liner extending into the bore so as to have a thickness greater than portions of the liner adjacent the aperture.
7 . The assembly of claim 6 wherein the cover member is provided in a cap and fasteners secure the cap to the support element.
8 . The assembly of claim 1 wherein the support collar includes a plate to which the cap is secured.
9 . A method comprising:
providing a liner disposed on a surface of a support element, wherein an aperture extends through at least a portion of the support element and opens to the surface and wherein the liner at least covers the aperture;
measuring a thickness of the liner from a back surface of the liner at least covering the aperture.
10 . The method of claim 9 and further comprising removing a portion of the fluid handling component to gain access to the back surface of the liner.
11 . The method of claim 9 wherein a cover member covers the back surface of the liner and wherein measuring comprises measuring through the cover member.
12 . The method of claim 9 wherein a portion of the liner having the back surface is thicker than the portions of the liner secured to the surface adjacent the aperture.
13 . The method of claim 9 , wherein measuring the thickness of the liner includes measuring the thickness of the liner through the back surface.
14 . The method of claim 9 wherein measuring includes measuring the thickness based on a sound wave transmission through the aperture.
15 . The method of claim 14 wherein measuring includes measuring the thickness based on a sound wave transmission through the cover member.
16 . The method of claim 9 wherein the liner and the cover member have similar sound propagation characteristics.
17 . The method of claim 9 wherein the liner and the cover member have operably dissimilar sound propagation characteristics.
