Roy E. Hanson Jr. Mfg. ASME Pressure Vessel Manufacturer

Hanson Tank 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 1 and HLW.

Founded in 1932, we have manufactured and shipped over a million pressure vessels 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.

We specialize in providing high-quality tanks to companies in many different industries, including but not limited to the following:
OEM’s, Hotels, Facility management firms, Engineering and procurement companies, Dairies, Apartments, Refrigeration, Energy sector, Transportation,
HVAC solutions, Municipal wastewater, Commercial wastewater, Clean energy storage and many, many more!
