RE: [PSUBS-MAILIST] viewports available online



 

 


 

Global warming has not yet reached 200m, hopefully. But how is the viewport attached to the hull ?

>> in case of the Peppers ,it is secured with 6  6 mm screws and sealed with silicone sealant in its aluminium dome ring. But there are more ways.

I sent offline some pictures of the seating.

> That dome - can it be used to 200 meters with standard safety factors ?
Maybe we can make a testchamber ?

>> The Küsters from Nemo uses also this dome. They want to test a damaged one to destruction when their test vessel is finished.

Their dome was damaged due to the wrong size o-ring in the o-ring groove in the dome. A o-ring groove in the acrylic is not a good idea  for frozen-water reasons!

Keep up the good work!
