An important part of quality assurance is the process of manufacturing a vessel and the completion of required certifications to meet ASME compliance. Equally important is the understanding of these processes and procedures, by all parties from project engineering manager to purchasing teams.
Apache's quality experts have put together a informative resource on factory tests and certifications for ASME tanks and vessels. It is important to have an understanding with customers about what is involved with testing and documentation requirements.

Brakebush Brothers, a leading processor of chicken products, worked with Apache Stainless Equipment Corporation to design, fabricate and deliver a new 20,000 gallon fresh oil tank for their Westfield, Wisconsin plant.
David Meyer, Utilities Manager at Brakebush, needed a new storage tank to keep up with production demands and chose Apache Stainless for it’s reputation as a quality manufacturer of stainless tanks and expertise in heat transfer surfaces and sanitary tank finishing. The 13’ 6” diameter tank is 33’ feet tall and replaces an 8,000 gallon tank that will be relocated to another Brakebush plant.
David Foulkes, Sales Manager for Apache, worked with Brakebush and Apache’s tank team to provide the new tank with specifications to include a containment shell, steam dimple jacket, insulation and protective shroud with controls to monitor and adjust the heat temperature of the oil, especially during the winter months in Wisconsin, as well as the required flow into the plant for production operations.
The Brakebush Westfield, Wisconsin plant has a production facility of over 500,000 sq. ft. with state of the art cooking operations. Westfield is also the corporate office for Brakebush.
Apache Stainless located in Beaver Dam, Wisconsin serves commercial manufacturers all across North America. Apache tanks are found in food and beverage processing facilities an in fuel refineries, ethanol plants, chemical industries, biotechnology and pharmaceutical companies and in health and beauty product manufacturing plants.
The main difference between pickle passivation and electropolishing is the appearance and RA (roughness average) of the stainless material. In the photo, an electropolished sample is shown above a pickle passivated sample. The pickle passivated sample has a white appearance, while the electropolished sample has a mirror-like, shiny finish.
Pickle Passivation is the immersion of metal in a pickling bath such as nitric-hydroflouric acid. The process removes metal such as impurities and heat marks from welds.
Electropolishing is an electro-chemical process that removes surface material from stainless steel. The process typically starts with an immersion of the component into a controlled bath of electrolyte that is charged with a DC power supply. Apache’s RA tests show improvements up to 50% smoother, depending on the material.
