  • Patent number: 5337792
    Abstract: A weather protector for the end of a pipe section, e.g. for use in a pipeline, tends to prevent the ingress of snow and rain into the interior of the pipe. The weather protector is made from a generally circular blank having peripheral tabs, a few of which are widely circumferentially spaced and are appreciably longer than the remaining tabs and extend over the edge of the pipe end. The weather protector is placed in the interior or the pipe, the tabs forming a substantially continuous cylindrical rim portion that engages the interior cylindrical surface of the pipe. The longer tabs position the weather protector in the interior of the pipe by overlapping the pipe end to prevent the weather protector from being pushed further into the interior of the pipe.
