What type of gauge is typically used to check the position of gaskets in concrete pressure pipeline joints?

The feeler gauge is specifically designed to measure gaps and clearances in various assemblies, which makes it suitable for checking the position of gaskets in concrete pressure pipeline joints. This tool consists of a set of thin, flat strips of metal, each with a different thickness, allowing for precise measurement of the space between components.

When installed in pipeline joints, gaskets need to be properly positioned to ensure an effective seal and maintain pressure within the system. A feeler gauge can be inserted into the joint to confirm that the gasket is aligned correctly, ensuring that it sits uniformly and tightly against the surfaces it is intended to seal.

In contrast, although other gauges like a caliper gauge or depth gauge serve specific purposes—measuring dimensions or depths—they are not tailored for assessing the minute gaps that a feeler gauge can accurately measure. A pressure gauge, as well, is used to measure the pressure within a system rather than the positioning or condition of gaskets. Using a feeler gauge ensures that technicians maintain the integrity of the pipeline joint by confirming gaskets are positioned correctly, which is critical for preventing leaks and ensuring the efficient operation of the pressure pipeline system.
