thread71-293823: Liquid Phase LPG Injector Calibration
I see last input was 2011. A lot of movement with propane as a motor fuel in USA.
We are building aluminium propane tanks and have been seeing many steel tanks with huge issues with rust etc internally.
Wondering if there has been any improvement with fuel quality/standards with all these new players in the market?
Thanks

I don't think a root cause has been determined or mentioned, but Blue Rhino is in the business of selling recycled, refilled propane tanks, so corrosion should be of interest to them.
Not coincidentally, I have noticed that "20 pound" propane tanks (which are now sold with something like 13 pounds of product inside) have gotten much, much lighter (tare weight) over the last couple of decades. They are now very similar (unbelievably thin) to the similarly sized single-use non-refillable-by-law tanks in which wholesale refrigerant is sold.
How much corrosion allowance do you build into your aluminum tanks?

Back to the OP. Rust has been a problem with steel cylinders but not widespread. Some do, most dont. Rust cannot form once a cylinder enters service as there is no oxygen to promote the formation. Any rust would be the result of the cylinder being opened prior to service and allowing oxygen and moisture to enter.
US Autogas quality standards have not improved in many years and its long overdue. This is a self assigned task I am pushing for. Lets hope it gets some attention.
Now, as to who and where is Turbo? That rascal!

Exchanges are prolifferating because the retailer does not need to have trained and licensed employees and extra insurance.

Presumably however it still falls within established API automobile standards - - ?
What brands if any retain the original specifications?
Is this an issue throughout U.S.A. and Canada?

Can you elaborate on this, I am using propane to power outboard motors, and would like to know of any potential problems before I encounter them. I already know about wax deposits.

You are describing good old American profiteering, it really has not changed, since the days of John Davison Rockefeller.

This is why some corrosion in some parts of the country and not others.
One tank I had a look inside with a camera had sheets of rust falling off inside - like it had been at sea for years.
The outside looked like new.
Another big issue is the particulates found in the fuel, causing issue to fuel pumps etc.
The graph I was shown showed they needed filtration down to 2 microns to catch the little sods.
Many believe including myself that with the huge increase we are starting to see with propane powered vehicles that a tighter quality control standard needs to be implemented.
Berkshire, what systems are you running on your outboards? injection/ vapour, liquid?
RE: Is turbocohen still onthis Forum?
They are vapour systems, using a modified carb, and a boiler running off the cooling water to ensure vapour is delivered to the carb.

I am well aware of the Blue rhino / Amerigas cylinder swap issues. The only thing they did around here, was to make the short weight label bigger.
My local jobber was selling at 2.99 per gallon until last week then they jumped to 3.49 citing some state tax increase.
