Avure Confidential, 2012 System Safety Andover accident 1998-07-26 Accident with a large monoblock vessel in USA (Competitor design) Large monoblock design with a threaded closure No frame was used for the pressure vessel The vessel failed most likely due to thermal stresses that were not taken into account The vessel failed most likely due to crack propagation from the outside of the cylinder The customer replaced the vessel with a QUINTUS® Press Avure Technologies Avure Confidential, 2012 System Safety Mono-block design: Monoblock cylinder The mono-block design has not got the advantages that the wire wound technique provides No pressure Pressure A monoblock vessel will never experience compressive stress on both inner and outer surface Leak before break will not be established Fatal failure will occur in case of a through the wall crack The design requires frequent, extensive and expensive safety related maintenance! Avure Technologies Avure Confidential, 2012 Failure mode: Catastrophic System Safety The mono-block vessel – A non-redundant pressure vessel concept with its roots in WW 1 battle ship gun barrel design The heat treatment of the forging is difficult to control Thick vessel wall Large tensile stresses Built in stress concentrations High risk for crack initiation Avure Technologies Any failure would be catastrophic! Avure Confidential, 2012 System Safety QUINTUS® design: The wire wound technique has got a lot of advantages compared to the mono-block design No pressure Pre-stressed thin-walled cylinder Pressure The pre-stressed vessel will always experience compressive stress on the inner surface A leak before break design secures that no fatal failure will occur in case of a through the wall crack Since the design is both safe and redundant, the need for frequent safety related maintenance is eliminated!
