Norris Cylinders Ready for Shipping

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.

Acetylene Cylinders

Acetylene Cylinders (14)

Acetylene Cylinders2

Norris Cylinder manufactures acetylene cylinders with a world renowned asbestos-free, lime-silica porous mass. As the original patent holder of this asbestos-free mass, we have licensed our asbestos free mass to manufacturers in Spain, Australia, Germany, Czechoslovakia, France, Austria, England and the United States.

In design, construction and workmanship, Norris Cylinder acetylene cylinders exceed normal industry requirements. Acetylene cylinders are available in a wide variety of sizes, specifications, and configurations with either acetone or DMF as the solvent.

Forged from steel disks that are cold cupped, drawn and welded to form a cylinder shell, our cylinders are manufactured in accordance with DOT 8/TC 8WM, DOT 8AL/TC 8WAM, or ISO-3807 specifications from the U.S. Department of Transportation, Transport Canada, or the International Organization for Standardization. The cylinders are designed to a settled service pressure of 250 psig at 70°F for a withdrawal rate of 1/7 of cylinder capacity per hour.

For other available sizes or customization options, please contact your Norris Cylinder Sales Representative or Customer Service for more information.
