INOVADRUM CLOSED UN

INOVADRUM CLOSED UN

Closed stainless steel drums, fully assembled using robotic laser fusion without filler metal, UN-approved for the transport of liquid hazardous materials. Thanks to their continuous surface design, with no gaps or retention areas, and their secure closure systems, this range ensures maximum tightness and minimizes contamination risks.

Capacities

Closure

  • Two openings on the top of the drum, equipped with standard machined ferrules: 3/4" (19.05 mm) and 2" (50.8 mm) with straight NPS threads;
  • 316 stainless steel plugs with PTFE seals, suitable for the constraints of hazardous materials.

Application areas

Uses

Suitable for the transport and storage of liquid and viscous hazardous materials, whether high value-added or posing a risk to the environment.

EXPERTISESTHE BENEFITS OF THE RANGE

Discover the main features of this product range.

Tightness

UN-approved closed drums, fully assembled using robotic laser fusion technology, provide maximum tightness thanks to their crevice-free design between covers and body of the barrel.

Each drum undergoes rigorous leak testing, including a pressure immersion test, ensuring detection of even the smallest leaks and guaranteeing optimal protection of hazardous materials.

This design effectively protects contents from external factors such as air, humidity, light, gases, and external contamination—even under the most demanding transport conditions.

Compatibility

Manufactured from high-quality stainless steel (304/304L or 316/316L), without varnish or internal coating, closed drums ensure excellent chemical inertness.

They are compatible with a wide range of liquid hazardous materials, including the most sensitive or reactive substances, such as nitric acid.

Cleanliness

Thanks to robotic laser fusion welding without filler material, which eliminates all retention areas, and to strictly controlled manufacturing and washing processes, the drums offer a high level of cleanliness.

Regulatory

This range is UN-approved for the transport of liquid hazardous materials, in compliance with international requirements (Transport Canada certifications).

Certifications:

UN/1A1/X1.2/600/YY

UN/1A1/X2.0/600/YY

Hazardous materials are liquid substances that, due to their physicochemical or toxic properties, present a serious risk to health, safety, property, or the environment, particularly during transport or handling. They may be flammable, oxidizing, toxic/infectious, explosive, corrosive, or radioactive.

Contact our experts to verify regulatory compatibility with your product.

Safety

Designed with 1.5 mm thick stainless steel, Inovaweld drums offer excellent resistance to impacts, punctures, and compression.

Their structure, assembled by robotic laser fusion, combined with secure closure systems, ensures maximum protection of hazardous materials throughout transport and handling operations.

Sustainability

Fusion-welded stainless steel drums provide a sustainable alternative to HDPE drums, lacquered steel drums, or crimped stainless steel models.

Reusable and designed for a long service life, they help reduce packaging waste while maintaining a high level of safety.

YOUR PACKAGING QUESTIONS

Are stainless steel drums recyclable?

Stainless steel is 100% recyclable. However, classification as a “contaminant-free” solution depends on the condition of the drum, the products it has contained, and how it has been maintained over time.

What are the advantages of maser welding technology?

The fully welded design eliminates crimped assemblies, reducing retention areas and making cleaning easier, while improving robustness and versatility of use. Laser welding does not require filler material, which reduces the risk of corrosion and internal porosity. As the heat-affected zone is very limited, internal stresses are reduced and the drum’s mechanical strength is enhanced, particularly in the event of impacts or drops.

What is the difference between 304/304L and 316/316L stainless steel?

300 series stainless steels share a common base, to which elements such as chromium, nickel, or molybdenum are added to define their properties. Grades 304 and 316 are non-magnetic.304/304L offers excellent corrosion resistance in standard environments and is a cost-effective solution, while 316/316L is designed for more aggressive environments, particularly in marine or chemical industries, thanks to its enhanced corrosion resistance.

CAN STAINLESS STEEL DRUMS BE CLEANED AND REUSED?

When used with products compatible with stainless steel and properly maintained, drums can have a very long service life. Replacement is generally linked to the use of unsuitable cleaning agents, especially chlorine-based products, or to mechanical damage during handling. In demanding applications, such as maple syrup, well-maintained drums can exceed 20 years of service life. Fully welded drums offer greater durability than crimped drums, whose design typically limits their lifespan to just a few years.
