Applications:

Non-upset(NU) tubing master gauges are mainly used in the petroleum oil and gas industry for measuring

the thread of casings, tubing and pipelines.

Precautions:

1. It is not allowed to touch the working surface of the gauge with your hands, so as not to cause rust.

2. Inspect regularly to see if there is any damage, rust or deformation. If you find that the gauge begins to rust,

you should put it in gasoline and soak it for a period of time, then take it out and wipe it carefully, and apply anti-rust oil.

will be glued to each other, and the gauge will be unnecessarily damaged when separated by external force.

4. After used the threaded gauges, it should be wiped clean and stored under dry condition.
