Benefits of Passivation and Electropolishing

Pickle passivation is the immersion of metal in a nitric-hydrofluoric acid bath. Pickled stainless material has a light matte appearance. Benefits include ease of sterilization and corrosion resistance.

Electropolishing is the immersion of metal in a charged bath of sulfuric and phosphoric acid. Benefits include ease of sterilization, improved cleaning properties, corrosion resistance and a mirror finish look.

Apache is a manufacturer of small and large vessels and food processing equipment. We can handle small parts or assemblies as large as our tanks that we build, with larger pieces possible with the use of fixtures or double dipping.

Spin the Wheel - Learn about our groups!


Apache Stainless has four different product groups, each specializing in working with stainless steel: Large ASME Tanks, Small / Portable Vessels, Contract Manufacturing and Mepaco - food processing equipment.

Our technicians and fabricators are versed in working across all product groups, which provides efficient production and creates a very skilled and knowledgeable production team. Apache's welders are ASME certified and newly hired welders are supported and trained to get their certification.

The Large ASME Tank group produces tanks in many industries using stainless and other high alloys. These tanks and vessels are constructed for fuel refineries, ethanol plants, chemical industries, food and beverage processing facilities, biotechnology companies, health and beauty plants and in water treatment facilities.

The Small/Portable Vessel group offers both a standard line and customized tanks and vessels, ranging from a few ounces to 100 gallons. These tanks and vessels serve industries that are highly regulated in terms of material, traceability, welds and governmental certifications.

The Contract Manufacturing group offers custom fabrication, assembly, gantry drilling, laser cutting, welding and metal finishing. Our in-house metal finishing includes pickle passivation and electropolishing. We can handle small parts and larger components, like our tanks, with the use of fixtures or double dipping techniques.

The Mepaco group offers a proprietary line of food processing equipment. With modifiable options, Mepaco's product line includes: cookers, mixers, blenders, augers, dumpers, sanitary conveyors and material handling systems.
