This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig. Such pressure vessels may be fired or unfired. Specific requirements apply to several classes of material used in pressure vessel construction, and also to fabrication methods such as welding, forging and brazing. It contains mandatory and nonmandatory appendices detailing supplementary design criteria, nondestructive examination and inspection acceptance standards. Rules pertaining to the use of the U, UM and UV ASME Product Certification Marks are also included.

Careful application of this Section will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.

The reason for such universal acceptance of ASME Sec VIII is essentially due to the following parameters:

  • ASME Sec VIII is one of the safest code and the safety margin is also high compared to other design codes.
  • ASME codes are updated every year based on the feedback received from the users and based on current industry scenario.
  • ASME being the largest committee for codes also ensures better and reliable experience. Interpretation of any code is always a complicated issue for engineers wherein the support provided by ASME through prompt replies helps the engineers to understand the technical aspect and expedites the engineering process.

The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels. The ASME works as an accreditation body and entitles independent third parties (such as verification, testing and certification agencies) to inspect and ensure compliance to the BPVC.
