Tanks

OR3 fabricates all kinds of stainless steel storage tanks and silos for multiple purposes and industries up to a diameter of 4500 mm, 24000 mm in height and up to 35 tonnes in weight at our workshops, and transport them by road or sea. Depending on the scope of the project, we also perform the construction of tanks directly on-site without limitations in technical design, size, or wall thickness.

OR3 produces stainless steel process tanks for various applications, including mixing liquids or powders, heating, cooling, and hygiene. Our engineering and production teams have extensive experience in designing and fabricating process tanks and equipment for mining, pulp-paper, energy, dairy and ice-cream manufactures, wineries, breweries, pharmaceutical companies, and many other industries.
We also design process tanks and equipment, perform the installation, de-installation of used machinery, carry out all piping and spooling works, quality control, hydraulic/pneumatic tests, thermal insulation of pipelines and commissioning.

OR3 manufactures chemical tanks and reactors in stainless steel or special alloys that can withstand high pressure, large temperature differences, and highly corrosive or abrasive contents. Our welders are PED-certified under the 2014/68/EC Pressure Equipment Directive. Thus, we are able to design and build PED-certified pressure vessels up to 300 m3 according to product standards such as EN 13480-4 and EN 14015.

OR3 manufactures and delivers custom mixing or storage atmospheric pressure tanks with heating or cooling for the pulp-paper, mining, food, pharmaceutical, chemical and energy industries.
Depending on the application and use, these non-pressurised vessels may have various tops, bottoms, jackets, working nozzles, hatches, agitators, and insulation.
