Off Shore Gages Print E-mail

After experiencing a problem on one of their off shore rigs, a major oil company requested that Penberthy initiate a research program to develop better corrosion protection for offshore gage glass. To assess the relative strengths and weaknesses of various coatings and materials commonly used as "offshore protection," we subjected a number of our own gages as well as competitive models to an accelerated corrosion/weathering test (ASTM B-117). While the tests were performed in a controlled laboratory environment, the exposure to over 2500 hours of heat and salt spray provided a corrosive environment that was judged to be comparable to two years of actual offshore use.

As a result of these tests, Penberthy has developed a unique three-part coating, applied to the components before the gage is assembled, to provide unprecedented gage protection in offshore application. The Penberthy gage also includes a variety of unique design features to further extend gage life.


Competitive comparison shows the need for concern in selecting a gage with "offshore" design

As important as coatings are in making a gage corrosion-resistant, their value can be rendered useless if the glass is left vulnerable to other types of damage. The total protection of gage glass is critical in complementing the effectiveness of offshore coatings.

The Penberthy offshore gage design is unique in its ability to completely isolate the gage glass from abrasive forces. This complete protection is important because even seemingly minor abrasions can cause the tempered gage glass to lose most of its pressure containing ability.

The following diagrams illustrate the relative vulnerability of the glass on competitive models.
