Hanson Tank (Roy E. Hanson Jr. Mfg.) is a major U.S. manufacturer of
carbon and stainless steel pressure vessels built to the ASME Boiler and Pressure Vessel
Code, Sect VIII, Div I and HLW. Founded in 1932 the company manufactures and ships
over 15,000 pressure vessels, with a value of over ten million dollars,
annually to destinations all over the world.
The ASME Boiler and Pressure Vessel Code is recognized world wide.
However, we also have the capability to build vessels to the requirements
of the US Coastguard, American Bureau of Shipping, Lloyd's of London, Det
Norske Veritas and other jurisdictions. Many purchasers of non-pressure
tanks also specify ASME Code construction in order to take advantage of
the strict quality controls that the ASME demands. All Hanson tanks, even
non-code, are build to Code standards and are pressure tested before shipment.
If you are in the market for one or one hundred carbon or stainless
steel pressure vessels from 15# to 3000# design working pressure in many
diameters, call us, fax us , or e-mail
us your needs for a prompt, courteous quotation.
Virtually all the steel we utilize is purchased in bulk direct from
domestic mills, and our huge inventory of raw materials ensures our customers
the fastest possible delivery at realistic prices. We also have special
arrangements with many major truck lines that mean that our top quality
vessels can be delivered to your facility for far less than you would imagine.
The US Army, Air Force and Marines all have Hanson tanks in facilities throughout
the nation and the world, and our pressure vessels were right
there in the Desert Storm campaign, hoisting antennas and
inflating aircraft tires among other less visible, albeit
The list of Hanson Tank customers includes many major corporations, who demand the highest engineering standards. They include Boeing, Chevron, Coors, Disney, Dow Chemical, Ford, Fluor, GE, GM, GTE, Hewlett-Packard, Hughes, Hyundai, Ingersoll-Rand, Lucasfilm, Mobil, NASA, Nike, Shell, Technicolor, Universal Studios, Unocal, Warner Bros. to name a few.
How do you test whether a large space rocket can be launched out of the back of a cargo plane? If your idea doesn't work, you've lost a very expensive rocket and possibly a cargo plane and its crew too.
Answer: You have Hanson Tank build a full size replica of your space rocket to test the idea. So that it's the same weight as a real one, you include several internal water ballast tanks that can also be used to distribute the weight precisely. So that you can run the test more than once, you also invest in some very large parachutes. But just in case, you also order another one as a spare.
These pictures are of the first one in our shop and later leaving on our truck on its way to have the nosecone and dummy rocket engine added.
A similar but unrelated test project was when the load capacity of the Chinook helicopter was being verified for an export order for 14 units worth $1.64bn from the British Royal Air Force. For this, we manufactured a water ballast tank with several internal compartments. This enabled the engineers to simulate operating conditions and test different weight distributions. It also might have been useful if they happened to encounter a brush fire during flight tests!
