Hi everyone..


I an still toying with two designs of PSUB, one larger, steel and with an  
AUX diesel engine 3PAX…. But also with a smaller 2PAX more mobile system and 
 have been looking into the possibility of using HDPE as a hull material 
for a  small 100msw PSUB

There is off the shelf (Sort of) 1000mm OD pipe here in Australia with a  
60mm wall thickness but I have also come across a 1360mm-OD and 1650mm-OD 
pipe  again with 60mm wall thickness that may be available. HDPE can be welded, 
 drilled and tapped quite well and using fittings/penatrators made of 
delrin  with o'ring seals has worked well on some camera housings I have made.


Has anyone looked further into this? is the wall thickness enough to just  
have bulkheads instead of stiffeners? no corrosion problems and it is super  
slippy in the water!


I have always looked at having HDPE battery pods, what not the whole  sub?
