Within the boiler, piping and pressure vessel industry, pressure relief devices are considered one of the most important safety components. These Devices are literally the last line of defense against catastrophic failure or even lose of life. Methods to assess the structural integrity of pressure vessels, piping, and storage tankage have been developed by a wide variety of sources. Of these efforts, the Materials Properties Council Program on Fitness-for-Service Evaluation Procedures for Operating Pressure Vessels, Tanks, and Piping in Refinery and Chemical Service is one of the.

    Gas Piping and Pressure Vessels. Gas piping and pipelines are considered critical systems at elevated risk of catastrophic failure with casualties and high economic damage. Also, number of pipelines and their capacity constantly increasing which makes routine inspection of such pipelines for flaws and leaks extremely important.

Developments in pressure vessels during the nineteenth and early twentieth centuries were accompanied by all-too-frequent catastrophic pressure vessel explosions. Disastrous accidents such as the SS Sultana () and the Grover Shoe Factory explosion () led to the development of basic standards for manufacturing and operation of pressure vessels.

Brittle fracture occurs when a vessel or piping is chilled due to auto-refrigeration and the excursion or post excursion stresses are sufficient to drive fracture at existing flaws. This behavior is often described by the brittle fracture triangle where closure of the triangle indicates the potential for brittle fracture.

This property of a “robust” structure, when coupled with a continuous or periodic inspection program using nondestructive evaluation (NDE) techniques, is useful in failure prevention, because such structure is expected to display “measurable” signs of “weakening” long before the Cited by: 1.

One such prevention action is to properly maintain your pipe supports to prevent sagging and localized low points where condensate can pool and flash on start-up. Piping failures related to pipe support deficiencies usually involve through-wall leak conditions although in rare cases, they can involve catastrophic ruptures.

Where there is a possibility of high-risk catastrophic failure, the consequences and risk to personnel, environment and equipment can be rendered tolerable to negligible if appropriate protective systems are in place with reduced maintenance and inspection.
