Ledwell & Son has been in the tank business for several years, building various types of water spray and dust control trucks and trailers. In early 2000, Ledwell & Son ventured into vacuum tanks, some smaller truck mounted tanks for non-industrial use and later “Saltwater” trailers used in the oil drilling industry.

Due to customer demand and market studies, Ledwell chose to take the next step and become fully certified to manufacture and repair Code tanks. Code tanks fall under various D.O.T. rules as well as being regulated by the American Society of Mechanical Engineers (ASME)and the National Board of Boiler & Pressure Vessel Inspectors.

After a lengthy education process and review by the Texas Department of Licensing & Regulation, Ledwell & Son became certified by ASME and The National Board on April 27, 2010. This certification allows for the manufacture of “U” stamped vessels and “R” stamped repairs to in-service tanks.

Ledwell has come a long way in a short time due to a great group of employees and continued support from our established vacuum customers and new ones along the way.
