Measuring Arc

The measuring arc is designed for use with the V-groove kit to verify groove dimensions on RTJ flanges. It provides a straightforward way to check critical dimensions during machining or inspection, helping to confirm that the groove profile and diameter meet requirements.

One practical advantage is that groove diameter can be measured while the ID-mounted flange facer remains installed. This reduces the need for repeated setup or removal, which can save time and helps maintain alignment during the job.

The arc covers a wide measuring range, with capability up to 1196 mm in diameter. Its open design allows access in situations where conventional measuring tools can be difficult to position, particularly on larger flanges or in field conditions.

Built for workshop and on-site use, the measuring arc is intended to be simple to handle, robust enough for regular use, and easy to read in typical working environments. It complements the V-groove kit as part of a practical approach to checking flange groove dimensions without unnecessary complexity.
