An ASME stainless steel pressure tank is a type of vessel that can store pressurized fluids or gases safely and effectively. ASME stands for American Society of Mechanical Engineers, which is a professional organization that sets standards and codes for various engineering products and practices. ASME pressure tanks are engineered and manufactured according to these standards and codes, ensuring their quality, reliability and safety. ASME pressure vessels are widely used in various industries, such as chemical, pharmaceutical, dairy, food processing, refrigeration, and energy.
Making an ASME tank requires a high level of skill and precision. Only a company that has the experience and reputation in the industry can do it. To make an ASME tank, a company needs to have the appropriate certification, equipment, and expertise. ASME requires the company to maintain a stringent quality control program/manual. The company must also have the appropriate ASME certification mark and designator for the type of tank it produces. Spokane Stainless Technologies maintains the following marks:
A company that can make an ASME tanks must follow the ASME codes and regulations, which specify the design, fabrication, inspection, testing, and operation of pressure vessels. The company must also have qualified engineers and welders who can ensure the quality and safety of the tank. Additionally, the company must have the necessary tools and machines to cut, shape, weld, and assemble the tank components. ASME certified companies are subject to periodic audits by ASME authorized inspectors, who verify that the companies comply with the applicable codes and standards. The audits are conducted in accordance with the ASME Accreditation and Certification Procedures, which specify the frequency, scope and criteria for the audits. The audits aim to ensure that the companies maintain a quality system that meets the ASME requirements and that they produce safe and reliable products.
The ASME U and UM marks are symbols that indicate the compliance of pressure vessels with the ASME Boiler and Pressure Vessel Code. The main difference between U and UM vessels is that UM marked vessels are smaller in volume and have less stringent inspection requirements than U marked vessels. For example, U vessels need a 3rd party ASME inspector to review the calculations and witness the hydro test, while UM vessels do not. In-House CI (Certified Individual that is tested and audited every year) can certify UM vessels for the ASME mark. UM vessels also have lower frequency of audits than U vessels. Both U and UM vessels can have similar operating pressures, depending on their size and design.
ASME tanks are not always a requirement, but they do offer some distinct advantages over non-ASME tanks. Some of these advantages are:
However, ASME tanks also have some disadvantages or limitations compared to non-ASME tanks. Some of these are:
Therefore, whether an ASME tank is a requirement or not depends on the specific situation and needs of each customer and/or process. Some customers may prefer or need an ASME tank for their application, while others may opt for a non-ASME tank that meets their expectations and budget. The best way to determine if an ASME tank is a requirement or not is to consult with a qualified and experienced tank manufacturer like Spokane Stainless Technologies who can provide professional advice and guidance based on the customer's requirements and specifications.

A UL142 tank is a type of aboveground storage tank that meets the standards of the Underwriters Laboratories (UL), a safety certification company. UL142 tanks are designed to store flammable and combustible liquids, such as alcohol and high proof spirits. It is manufactured according to the UL 142 standard, which covers the tank materials, construction, performance tests, markings, and production line tests. A UL 142 tank can have various shapes, orientations, compartments, and supports, depending on the application and installation requirements. A UL 142 tank can also have a primary or secondary containment, or both, to prevent leakage and environmental contamination. A UL 142 tank can withstand a maximum working pressure of 0.5 psig as measured from the top of the tank .
To make a UL142 tank, one needs to follow the specifications and requirements set by UL. The company must have the appropriate equipment, materials, and quality control procedures to ensure compliance with the UL specifications. The company must also be certified by the UL or an authorized third-party organization to perform the fabrication, testing, and labeling of the tanks.
A UL 142 tank is a type of steel tank that meets the standards of the Underwriters Laboratories (UL) for storing flammable and combustible liquids.
A company that makes distilled spirits may need a UL 142 tank for several reasons:
A UL 142 tank can meet these criteria and ensure the quality and safety of the product. By using a UL 142 tank, the company can ensure that it complies with the relevant laws, insurance requirements, and standards that govern the safe production, storage, and distribution of distilled spirits.
A DOT certified tank is a type of container that meets the safety standards of the U.S. Department of Transportation (DOT) for transporting hazardous materials. A DOT certified tank is required when the material being transported is flammable, corrosive, toxic, or otherwise poses a risk to public health or the environment. The DOT regulates the design, construction, testing, inspection, and maintenance of these tanks to ensure they can withstand the pressure, temperature, and mechanical stress that may occur during transportation. A DOT certified tank is also marked with a label that indicates its specifications, such as capacity, pressure rating, and material compatibility.
Some examples of materials that require a DOT certified tank are gasoline, propane, ammonia, chlorine, and hydrogen. These materials are classified as Class 2 (gases), Class 3 (flammable liquids), Class 4 (flammable solids), Class 5 (oxidizers), Class 6 (poisonous substances), Class 8 (corrosive substances), or Class 9 (miscellaneous hazardous materials) by the DOT. The DOT also assigns a four-digit identification number to each material, which must be displayed on the tank along with other placards that indicate the nature and degree of the hazard.
A DOT certified tank is not required for materials that are not regulated by the DOT, such as water, food, or non-hazardous chemicals. However, some states or local authorities may have additional requirements for transporting these materials, so it is advisable to check with them before transporting any material in a tank.
A DOT certified tank is a type of pressure vessel that meets the safety standards of the U.S. Department of Transportation (DOT). To engineer and build a DOT certified tank, a company needs to have the expertise, equipment and quality control systems to ensure compliance with the DOT regulations.
