Aluminum brings a distinctive combination of light weight, good corrosion resistance, and excellent low-temperature toughness to process equipment. Roben Manufacturing fabricates aluminum vessels and components for applications where these properties matter — from weight-sensitive installations to cryogenic service where aluminum actually grows tougher as temperatures fall.
Aluminum is not interchangeable with steel; it has its own design rules, welding requirements, and strength characteristics. We bring the specific expertise aluminum fabrication demands, so the finished equipment takes full advantage of the metal's strengths while respecting its limits.
Lightweight, Corrosion-Resistant Aluminum Fabrication
Aluminum's most obvious advantage is weight: at roughly a third the density of steel, aluminum vessels are far easier to transport, lift, and support. That weight saving can simplify foundations and structural steel and reduce installation cost, which is why aluminum is favored for elevated, mobile, and transport applications.
Aluminum also forms a self-healing oxide layer that gives good resistance to many atmospheric and chemical environments, and it has outstanding toughness at cryogenic temperatures, where many steels become brittle. These properties make aluminum a natural choice for certain low-temperature and corrosion-resistant duties.
Welding aluminum requires dedicated skill. The metal's high thermal conductivity, its tenacious oxide layer, and its sensitivity to contamination all demand specialized technique, clean preparation, and the right filler alloy. Our procedures address these factors so that aluminum welds achieve the required strength and soundness.
Aluminum vessels are designed to the applicable code using aluminum's allowable stresses and design rules, and they ship with full material traceability and weld documentation. We advise on temper and alloy selection so the finished equipment meets its strength and corrosion requirements.
