that the paper seals as you say are not to be considered, how do you think of such an application? we are in 2010, there are many materials and many options to use that are feasible. Have you ever seen insert a paper seal between a insert and a hole created in a dissimilar metal?
but you did not consider contact of screw couplers/mother screws! under head you can put (as you say) a washer of the same material of one of the two elements, but the contact point of the threads is not good!:finger:
I almost forgot! is called vinyl tape what you could use at the point of contact between two different surfaces! but it is not to be considered in these circumstances! :finger:
I meant the paper seal because it costs much less than a stainless steel washer.
Why can't you put it?
There may be problems like this, but it depends on the treatment applied to the screw and who installs the screw (disting the element by ruining the treatment)! is to be kept in mind if the screw will be dismantled and reassembled frequently!
I had assumed that, given the criticality of the environment, once the screws were dismantled for maintenance operations, these were replaced with new ones.
excellent observation, but corrosion on the insert? You should also remove the insert that in the clamping phase may have suffered superficial damage, causing problems!
I mean? What does your comment mean?
I was wrong with the odds!
Here is who I had to apply the quota! thanks erpresident!
I was wrong to type the odds! Thank you for making me notice!
in the sense that the ddp that is created is reduced and the speed of oxidation is aboundingly higher than the 5 years of guaranteed duration
