There are many industry specific certifications in vessel manufacturing that regulate the construction of a vessel. However, for many types of pressure vessels, ASME certification is required and may be in addition to other industry requirements due to the vessel's geometry and pressure designation. Any tank that meets the requirements of ASME Code Section VIII can be certified. This certification is frequently referred to as "stamped" because the code symbol is most commonly applied using a stamp process. Here are the main differences between ASME U and ASME UM symbols and certification.

Note that there may be exceptions to the ASME Certification requirements, depending on your state and local municipality.
Apache manufactures tanks and vessels for compliance and regulated industries, including pharmaceutical, food and beverage, petrochemical, biofuels, chemical and life science. We hold these certifications: ASME U Certificate, ASME UM Certificate, National Board of Boiler & Pressure Inspectors R Certificate, and National Board of Boiler & Pressure Vessel Authorization to Register Certificate.

Apache is a custom manufacturer of tanks and vessels. Due to our customized offering, we want to provide the exact vessel you need; and that might lead to many questions and back and forth responses. If you don't have a specification list, here are 5 recommendations for you to determine when ordering a tank.
1. Determine pressures and temperatures. The design criteria, pressures and temperature requirements will impact material grades, thicknesses, compatibility of fittings and components, and elastomer selection. The following items may help to determine pressures and temperatures.
2. Determine type of certification required. It is advantageous to identify the types of certification and documentation (turn-over packets) that will be required for planning purposes. The following are common requested certificates.
Emerging market start-ups can have production challenges when their business takes off at a faster rate than planned. Here's a problem that Apache helped to solve.
Problem: A fast-growing botanical extraction processor was unable to produce the quantity of product needed to fulfill demand. Their process involved an imported vessel that was placed in a rudimentary ice bath for temperature control. This process resulted in waste of non-consistent product and constant staffing and manual intervention to monitor and adjust.
Solution: Apache's small vessel team provided an ASME processing vessel that completely replaced their batch process. The new vessel was designed with a thermal heat jacket that heated and cooled the product to the exact temperature required for the extraction process. The ASME vessel was jacketed with tri-clamp ferrules and included a site glass and high-pressure sanitary fittings. The vessel has a pickle passivated finish that provides ease of sanitation between batches.
Apache's vessel runs continuously day and night; it quadrupled production, eliminated product waste and removed employee monitoring and intervention.
