The American Society of Mechanical Engineers

Is a professional organization with the purpose of developing quality standards to govern the manufacturing of pressure vessels.

Engineered Pressure Vessels, LLC. is one of the companies in the United States with a Quality Assurance System Certified by ASME, where our commitment to quality is documented in each and every one of the projects we undertake.


Why is ASME so important to Engineered Pressure Vessels?

Because to comply with the Rules for Construction of Pressure Vessels of ASME Boiler and Pressure Vessel Code, we make sure you are getting a safe product at the highest quality.
When you require a Pressure Vessel, be sure to tell your supplier they must meet the ASME Code, specifying the total compliance with ASME Code Section VIII Division 1, Latest Edition.

By their general nature, Pressure Vessels require expertise to be manufactured; knowledge and expertise are keys to the production of safe and long lasting Pressure Vessels.

Custom tailoring the product to meet your specific needs is very critical, and an area at which we excel.

The ASME Code is divided into eleven sections and each of them, deal with particular areas, but there are four sections of the ASME Code we are involved with day to day when we manufacture a Pressure Vessel:

Section VIII Division 1: Establishes the rules for construction of Pressure Vessels.

Section II: Is divided into four parts: A, B, C and D.

Part A: Shows all the Ferrous Material Specifications such as Quality, Chemical Composition, Tensile Requirements, etc.

Part B: Shows the Nonferrous Material Specifications.

Part C: Shows the Specifications for Welding Rods, Electrodes and Filler Metals.

Part D: Shows the Properties for Ferrous Materials.

Section V: Determines the Rules and procedures for all Nondestructive Examination: Radiographic, Ultrasonic, Liquid Penetrant, Magnetic Particles and Leak Testing.

Section IX: Relates to the Welding General Requirements such as Procedure Qualifications, the Qualification of Welders, Welding Operators and Brazing Procedures, Welders, Brazers, and Welding and Brazing Operators. Once any ASME Stamped Pressure Vessel is manufactured, it is checked, tested and approved by the ASME Authorized Inspector, who reviews all the procedures and all the documentation and signs the Data Report Form before stamping the name plate with the “U” or “UM” symbols, which means that the Pressure Vessel fully complies with the ASME Code rules for construction of Pressure Vessels.

For The National Board of Boiler & Pressure Vessel Inspectors registration, we account with the “NB” Symbol as well as the “R” Symbol to Repair or to Alter any previous Stamped Pressure Vessel.
