  • Guide to ASTM Stainless Finishes Posted 5 months ago
    ASTM (American Society for Materials and Testing) was developed to set standards for chemical, mechanical, physical, and electrical properties of material, as well as testing standards for materials.  ASME (American Society of Mechanical Engineers) includes ASTM standards, AWS (American Welding Society) standards and other nationally and internationally recognized standards as part of a widely adapted design specification for many structures, including pressure vessels. Apache has substantial capabilities for mechanical and chemical finishing having supplied stainless equipment to hygienic industries for more than four decades.  Passivation, pickle passivation and electropolishing processes and associated ASME testing, and processes are 100% in-house.     Passivation is the removal of excess iron or iron compounds from the surface of stainless steel by means of a chemical, typically an acid based solution. Unlike pickle passivation, no metal is removed from the surface during the process. The process has little effect on the RA values of the stainless material being passivated. The ASTM A967 is a passivation standard that applies to the cleaning, passivation, and testing of stainless parts.  Pickle Passivation is the immersion of the metal in a pickling ...
  • What's Right for my Operation: Pressure v. Vacuum Closures Posted 2 years ago
    Vacuum or Pressure closures for small/portable ASME vessels Many processors come to Apache for a vessel solution in the incubation stage of their business.  In some cases, they are looking for help to choose the right kind of vessel that will suit their needs and fit their budget.  While Apache provides custom ASME vessels for a range of industries, we also offer a line of standard vessels that often solve what these manufacturers need for their process. The use of the vessel will determine whether it is a pressurized solution, non—pressurized or vacuum vessel solution.  Vessels that require a minimum of 50 PSI, utilize a pressure closure.  Numerous applications, including heating or cooling process, containment, and pressurized dispensing often utilize pressures at or above 50 psi.  It is important to note the safety and ASME requirements for pressure vessels, an ASME UM-mark is required for: Vessels 5 cubic feet of volume or smaller with pressures not exceeding 250 psi. Vessel 3 cubic feet of volume or smaller with pressures not exceeding 350 psi. Vessels 1.5 cubic feet of volume or smaller with pressures not ...
