The User is responsible for defining all applicable loads and conditions acting on the pressure vessel that affect its design. These loads and conditions are specified in the User’s Design Specification. The manufacturer cannot include any loadings or conditions in the design that are not defined in the UDS. Read more

What is ASME Section VIII, Div. 2? ASME VIII-2 contains mandatory requirements, specific prohibitions, and non-mandatory guidance for the design, materials, fabrication, examination, inspection, testing and certification of pressure vessels and their associated pressure relief devices. This Code is also applicable to those chambers of combination units that are in the scope of ASME VIII-2. Read more

Tall pressure vessels are generally defined as those where the height to diameter ratio (H/D) is more than 15. These vessels are built these days as self-supporting structures, i.e., they are supported on cylindrical or conical skirts with a base ring resting on a concrete foundation and firmly fixed to the foundation by anchor bolts embedded in concrete.

Inspection of Repairs BOTH the National Board Inspection Code and API 510 require the acceptance of repairs to a pressure vessel by the authorized inspector BEFORE the vessel is returned to service. The authorized inspector will normally require performing all of the nondestructive examinations for the repair that were required by the ASME Code during original construction. Alternative NDE methods can be proposed (such as the substitution of UT for RT) when it is not possible, or practical, to use the NDE method that was used during construction. Read more

National Board Inspection Code vs. API 510 This article discusses the steps in how a facility would need to go about getting one of their coded pressure vessels repaired, altered, or re-rated. The article will cover pertinent code and jurisdiction requirements and the differences among the American Society of Mechanical Engineers (ASME) Code, the National Board Inspection Code (NBC), and American Petroleum Institute (API) requirements; as well as discuss the following: design of repairs; planning and approval; responsible organization; materials; replacement parts; welding; postweld heat treatment (PWHT); inspections and hydrotest procedures; and documentation.

Pressure Vessels are containers which are designed to hold liquids, vapors, or gases at high pressures, usually above 15 psig. Examples of common pressure vessels used in the petroleum refining and chemical processing industries include, but are not limited to, storage tanks, boilers, and heat exchangers. Read more

REPAIRS AND ALTERATIONS – Part 1 Owners and Operators – do you have equipment you are using that could really use some updated to make them more efficient? Nozzles too small or large? Vessel needs a repair or a nozzle replacement? This is all too common in the Oil, Gas and Chemical industries where vessels may remain in use for 30 years or more. Read more

brittle fracture of pressure vessels

Volume X: ASME Pressure Vessels

Dec 01, 2016

The major concern for low temperature pressure vessels is brittle-fracture phenomenon which can be a cause for vessel failure. Many metals lose their ductility and toughness; they become susceptible to brittle fracture as the metal temperature decreases. Learn more today. Read more
