Over the past few years, since I’ve been working out of the Northern Rockies in the oilfield, running fishing tools, a lot of my friends have asked me what, exactly, do I do.
As I said in my last column, after years, indeed, of trying to keep air in pressure tanks, our industry figured out that the air was being eaten by the water.
In my last couple of columns I have reviewed the construction, sizes and unique fittings for typical hydro pneumatic tanks still made today, that were popular before about 1955.
