Custom Vessels

A-P-C are recognized as a world leader in the field of custom and general purpose vessel fabrication. They have been in business since 1929, and their products have set new industry standards for quality. Continual investment in the latest manufacturing technologies combined with deep industry insight allows them to develop fresh approaches and innovative strategies for pressure vessel design and fabrication.

Utilizing sophisticated CAD tools to ensure the products conform to the heat transfer, agitation, and hygienic requirements of your individual application. Built to meet or exceed ASME, UN, or DOT codes, they use only premium quality materials including stainless steel, Hastelloy, Monel, and duplex steel grades. Operating two large manufacturing plants housing state-of-the-art machine tools, welding equipment, and electropolishing facilities and using various automation technologies ensure precise and repeatable production of vessels in almost any configuration from one litre to 1900 litres in size. Options are numerous and include items such as valves, closure assemblies, dip tubes, level gauges, and more. Their ISO 9001:2015 quality control system ensures that your products have been properly constructed, tested, and inspected according to the most rigorous standards.

Dimpled Heat Transfer Pressure Vessels

Adding a full dimpled stainless steel jacket and bottom head to your pressure vessel increases heat flow in the passages created to maximize the customized vessel’s ability to transfer heat.

Available in volumes from 7.6 to 1900 litres (2 to 500 gallons), dimpled heat transfer pressure vessels range in diameter from 229mm to 915mm. (Insulation and a stainless steel shroud, if required, add approximately 50mm to the vessel’s diameter.)

Dimpled heat transfer pressure vessels jackets are generally made from 304 stainless. Thermolux paint and chloride-free insulation help to eliminate vessel corrosion and stress cracking. Special tank sizes, fittings, accessories and polishes are also available.

Portable Process Stainless Steel Vessels

Custom designed specifically for your process to ensure maximum cleanability, releasability and hygiene, our pharmaceutical process stainless steel vessels have volumes ranging from 3.8 to 1900 litres (1 to 500 gallons), and outside diameters ranging from 200mm to 1219mm.

Specific diameters and sidewall configurations can be selected to optimize your process and minimize your costs. In addition, a full baffled jacket or a full dimpled side jacket and bottom head can be specified to maximize your vessel’s heat transfer capabilities, with optional Thermolux paint and chloride-free insulation to help reduce stress cracking and corrosion. A shroud of Type 304 or other stainless steel can be used to cover the insulation.

PORTABLE STORAGE VESSELS

Ranging in volume from 3.8 to 1900 litres (1 to 500 gallons), with outside diameters from 229mm to 915mm, our portable storage stainless steel vessels are available with the same fitting, accessory and construction material options as our portable pressure stainless steel vessels.
