Tungsten Carbide/Molykote/Xylan Coating for the upstream equipment (Oil and Gas)
Tungsten Carbide/Molykote/Xylan Coating for the upstream equipment (Oil and Gas)
(OP)
Hi All,
In my current company, we often recommend tungsten carbide, molykote and xylan coatings for upstream equipment.
The reason for coating? Probably to increase the lifespan and the prevention of any corrosion.
Often, I hear the word, "cycle" being used.
I am curious. How do one define "cycle"? For example, xylan can last 10 cycles. What are 10 cycles equivalent to?
Thanks for the kind help in advance.

Just 1 question, could it co-relate with number of hours?
Thanks,

There should be a basic correlation between number of hours and number of cycles. Contact Whitford to discuss expected lifetime of Xylan in your environment.

As others noted, coatings like MoS2 DFL or Xylan applied to fastener threads are probably rated based on installation/removal cycles. This data is typically an average result from testing a number of similar specimens under controlled conditions. Coatings applied to surfaces for corrosion protection can improve fatigue characteristics of a metal component by preventing formation of surface defects from corrosion. Presence of surface defects will reduce the statistical fatigue life of a metal component.

Thank you for the explanations. I will take note of that.
Cheers,
