With over 70 years of experience, our quality DOT high pressure, seamless steel cylinders are widely used for shipping, storing, and dispensing industrial gases. Our high pressure cylinders are fabricated from chromium-molybdenum steel and produced in strict compliance with all applicable DOT/TC specifications.
In order to keep our exceptionally high level of quality control, Norris Cylinder closely monitors incoming materials for chemistry, grain size, and freedom from laps, seams, cracks, and inclusions. Our DOT cylinders are manufactured by several methods including plate drawn and hot billet pierce, which produces a seamless cylinder with the bottom integral to the sides.
For other available sizes or customization options, please contact your Norris Cylinder Sales Representative or Customer Service for more information.
