Hi Pipe insulation is a good concept for pc up here we get anywhere
from -20c average but in jan,feb, it can get to -50c so it is
fesable.The oilfield up here will go for this if it can be presented
in a profesinal manner ,the other thing is vandilisom,we have had
several bombs set off at well sites in years gone by and if this will
absorb bullets also they will use this no sweat.These well sites are
very remote and is hard for security to keep an eye on all the roads
at one time so this is a fesable product for them if you can coat the
pipe where it comes out of the ground and to the compresser station.I
think some tests at the rifel range will be in the future to see how
thick you would need for protection of the pipe.They use steel
buildings now but building a pc building on site would be the key for
explosion profing these sites.We have alot of sour gas wells up here
so the danger is great for any familys close to any of these well
sites.A table an the next oil mans show is definatly in the
future.Well its time go plow snow now so have a great day,Clair
