Is there a wear inspection ring gauge for tapered plug gauge for PT pipes?
There is no lineup of standard products.
Originally, PT's tapered plug gauge for pipe wear inspection ring gauge does not have a JIS standard.
OSG will be able to manufacture special products according to original standards.
This is OSG's own number for the purpose of determining whether the PT tapered plug gauge is within tolerance.
Therefore, please consider using it in combination with a calibration method based on JIS (four-needle method in the case of tapered plugs for pipes gauge ) or after confirming the operation with the other party.
In addition, there is a description in JIS (JIS B 0262) that the tapering gauge gauge for PT pipes uses a set of plugs when they are newly manufactured, and the effective diameter, pitch, and half angle of the mountain are inspected from the deviation of the end face of the small diameter.
Therefore, only in the case of a set of plugs and rings, the tapered plug gauge for PT tubes can be used as a guide for wear inspection if the misalignment of the end face is less than 1/4P using the "ring gauge of the set".
However, if you want to use it as a wear inspection, the ring gauge of the set should not be used normally, but should be used only for wear inspection.
* Since the wear limit of the gauge of PT is not specified in JIS, it conforms to the gauge of the thread symbol R.
* The pass/fail judgment of 1/4P or less is outside the JIS standard and is OSG's own setting.
In the case of a tapering gauge for PT pipes purchased separately as a set, it is a special product (PTW).
