Abstract
A marker is provided for attachment to a pipe or other vessel which periodically requires inspection for wall thickness at a specified, defined position. The marker has minimum surface contact with the pipe to protect against moisture accumulation between them. The marker is attached to the pipe or vessel by an attaching cable which also has reduced or minimum surface contact with the pipe. The marker is provided with a lock mechanism and a protective cover to protect the test area from contact by cleaning substances such as sand during sandblasting, as well as coatings or paints applied after cleaning.
Claims15
An inspection point marker apparatus for indicating a test point on a vessel for testing purposes, comprising
- a label plate member having an opening formed in it for passage of a test instrument to the test point and identifying the location of the test point on a surface of the vessel;
- a cover plate member mounted with said label plate member for covering said label plate member opening to protect the test point;
- said cover plate member being movable with respect to said label plate member for access to the test point;
- a connector for mounting said label plate member on the vessel;
- spacer members formed on said label plate member extending inwardly from said label plate member toward the vessel and having end portions making point contact with the vessel surface for maintaining said label plate member out of contact with the vessel surface.
An inspection point marker apparatus for indicating a test point on a vessel for testing purposes, comprising
- a label plate member having an opening formed in it for passage of a test instrument to the test point and identifying the location of the test point on a surface of the vessel;
- a cover plate member mounted with said label plate member for covering said label plate member opening to protect the test point;
- said cover plate member being movable with respect to said label plate member for access to the test point;
- a locking mechanism for locking said cover plate member in position covering said label plate member opening;
- a connector for mounting said label plate member on the vessel;
- and
- spacer members formed on said label plate member extending inwardly from said label plate member toward the vessel for maintaining said label plate member out of contact with the vessel surface.

- a cover plate member mounted with said label plate member for covering said label plate member opening to protect the test point;
- said cover plate member being movable with respect to said label plate member for access to the test point;
- said cover plate member being pivotally mounted to said label plate member for access to said test opening;
- a connector for mounting said label plate member on the vessel;
- and
- spacer members formed on said label plate member extending inwardly from said label plate member toward the vessel for maintaining said label plate member out of contact with the vessel surface.
An inspection point marker apparatus for indicating a test point for testing purposes on a vessel having a curved wall, comprising:
- a label member identifying the location of the test point on a curved surface of the vessel wall;
- said label member being curved to conform to the vessel wall;
- said label member having an opening formed in it for passage of a test instrument to the test point;
- and
- a ribbed cover plate member removably mounted with said label member for covering said label opening to protect the test point;
- spacer members formed on said label member extending therefrom for maintaining said label member out of contact with the vessel surface.
