Sanitary Process Tanks

Apache’s in-house processes and expertise in compliance and surfaces finishes, gives Apache a competitive advantage in providing Sanitary Process Tanks. Our sanitary tanks are found in the food, beverage, pharmaceutical, biotechnology, water filtration and health and beauty industries.

We have provided cook tanks, mixing tanks, heat exchangers, process tanks and storage tanks with sanitary design requirements. We have also manufactured tanks and vessels for WFI (Water for Injection) and CIP (Clean-in-Place) processes.

Apache also has in-house capabilities for passivation and electropolishing stainless finishes, if required for the application.

  • Comparing Base, Mid, and High-level Sanitary Finishes [Infographic] Posted last month
    Categorizing levels of sanitary design is helpful to professionals new to compliance regulated industries requiring custom vessels because it bridges communications regarding standards and design requirements. In hygienic applications, stainless equipment requires a sanitary finish which generally refers to a smooth, scratch-free, non-corrosive finish.  The fineness of the finish, which determines its performance, is measured in RA (roughness average). The infographic illustrates the RA of different types of mill, mechanical, and chemical finishes.  The smaller the RA reading in microinches (height in millionths of an inch), the smoother the finish.  When collaborating to qualify a project, we define a Base Level Finish as a 2B/Mill, 304 or 316 stainless materials that is pickle passivated.  The welds are continuous and crack and crevice-free.  This type of finish is paired with a Base Level Sanitary Design and is cleaned manually. Apache’s standard portable vessel line are an example of the base sanitary design and finish level. A Mid-Level Finish is also composed of 304 or 316 stainless material and involves a secondary process of mechanical polishing greater than 32RA, with final finishing to include pickle or ...
  • Anatomy of a Sanitary Design Vessel Posted last month
    When evaluating a custom vessel manufacturing partner for a new project, consider the manufacturing capabilities and experience that support the vessel’s application and sanitary requirements. All custom design stainless vessels for the food, life sciences, pharmaceutical and health industries require sanitary construction. It is the application and automation that drives the level of sanitary componentry. In reviewing each new custom vessel project, Apache identifies the sanitary requirements to categorize the vessel into a base, mid- or high-level design.  Apache offers a standard line of vessels that qualify for various regulatory compliance agencies.  However, these designs are considered a base level sanitary design, especially because the cleaning of the equipment is manual.  Apache identifies a mid-level sanitary design vessel as having COP (Clean Out of Place) components. In the video, a custom vessel is animated to walk through characteristics and examples in the highest and most automated level of sanitary design custom vessels. High-Level Sanitary Design Characteristics Include: CIP (Clean in Place) Process and Components Continuous, crack and crevice-free welds, ground flush and polished smooth to specific RA (Roughness Average) <32 RA 304 or 316 stainless material, mechanically ...
  • Navigating Stainless Material and Finishes for Hygienic Vessels Posted last month
    Stainless Finishes for Hygienic Vessels are measured by an RA (Roughness Average) meter.  Manufacturers of custom vessels for life science, health and pharmaceutical industries adhere to strict design parameters to maintain compliance in these industries. The RA is a standard for an average of peaks and valleys on the metal’s surface, measured in microinches.  Here is the evolution of stainless material coming to Apache with RA designations as it is transformed into custom sanitary design vessels: RA > 100 Mill Finish  A Mill Finish has an unpolished, dull-gray, matte appearance. This material type is the basis for supply for all stainless-steel flat products as well as the basis for additional finishing operations.  It is hot or cold rolled with an RA (Roughness Average) of more than 100 microinches, depending on the gauge of the material.  RA 15 – 40 2B Mill Finish  2B Mill finish is widely used in food, chemical and pharmaceutical equipment applications. It is corrosion resistant and has a typical RA range of 40 (7 gauge) to 15 (16 gauge) microinches. RA 29 – 58 No. 3 and No. 4 ...
  • VIDEO: The Affect of Manufacturing Processes on Stainless Surface Smoothness Posted 4 months ago
    The particular RA (Roughness Average) value is a requirement for stainless vessel manufacturing for federal, state or local compliance agencies across many critical industries. It is a crucial standard in these industries to maintain a clean system. The instrument used in the measurement is called a profilometer, which provides an average in micro inches. The smaller the number, the smoother the stainless material. It is common for high compliance vessels to have single digit RA readings on product contact surfaces. In the construction of pharmaceutical, life sciences, or medical-use vessels, meeting the RA requirement may include several steps, including material selection, grinding, polishing and chemical finishing. Manufacturing processes can affect the RA measurement on stainless material, including forming, stamping and welding. In the video, we walk out of the manufacturing plant with our quality controls manager to show measurements on material in vessels being manufactured in various stages of production.  Pickle Passivation and Electropolishing chemical finishes have a high degree of improvement on RA smoothness compared to material before it is treated. Pickle passivation, also referred to as descaling, removes the ...
  • Video: 3 Levels of Sanitary Construction Posted 5 months ago
    Processors serving food or hygienic industries have varying degrees of compliance requirements for custom vessels solutions.  The designation of "sanitary" has a wide range of definitions depending on the customer, the industry or the standard.   This video is a brief overview how Apache defines a base, mid, and high-level sanitary vessels.   Apache Stainless Equipment Corporation is a manufacturer of stainless equipment for a range of hygienic industries, including, food, beverage, biotechnology, pharmaceutical, cannabinoid, and life sciences. A dedicated quality control and compliance team directs all tests, certificates and documents for all sanitary, ASME, and global standards.
