HANSON LEGACY

Three generations of engineering excellence. Over a million pressure vessels shipped worldwide. The Hanson Standard since 1932.

Our Story

Founded in 1932 by Roy E. Hanson Jr., our company has been at the forefront of ASME pressure vessel manufacturing for over 90 years. What began as a small fabrication shop in Los Angeles has grown into one of the nation's premier manufacturers of custom and standard pressure vessels.

Through the Great Depression, World War II, and into the modern era, Hanson Tank has maintained an unwavering commitment to quality, safety, and engineering excellence. Our vessels have served critical applications in aerospace, defense, energy, and industrial sectors worldwide.

Today, we operate from our vertically integrated facility in Los Angeles, employing certified welders, engineers, and craftsmen who continue the tradition of precision manufacturing that has defined our company for nearly a century.
