1) Corrugated surface corrosion: Spectral analysis found that the concentration of non-ferrous metal elements is abnormal, and the sub-micron-scale wear particles of many non-ferrous metal components are present in the iron spectrum. The lubricating oil has excessive water content and acid value overrun.
2) Shaft surface corrosion: Spectral analysis found that the concentration of iron is abnormal; there are many submicron particles of iron in the iron spectrum; the moisture overrun or the acid value overrun of the lubricating oil.
3) Spine external strain: iron-based cutting abrasive black oxide particles in the iron spectrum; tempering color on the metal surface.
4) Fretting wear on the back of the tile: Spectral analysis found that the iron concentration was abnormal; there were many iron-submicron wear particles in the iron spectrum; the moisture and acid value of the lubricating oil were abnormal.
5) Bearing external strain: cutting abrasive grains are found in the iron spectrum; the abrasive grain composition is non-ferrous metal.

Gaugeable Tube Fitting

The fitting design for tube connecting, and have been used for marine, mechanical connect, chemical and else.

This design is standard on all 1/4 to 1 in. and 6 to 25 mm stainless steel tube fittings to help installers make more consistent, leak-tight tube connections. In these sizes, a patented case hardening process and patented recessed and contoured geometry provide a unique engineered advantage to the Swagelok back ferrule, providing:

1. excellent gas-tight sealing and tube-gripping action

2. easily achieved proper installation

3. consistent remakes

4. excellent vibration fatigue resistance and tube support

5. full compatibility with stainless steel tube, copper tube and else.
