... for Class II vessels be carried out at operating temperature in the event that the operating temperature exceeds 49 ° C ( 120 ° F ). Lack of data from fiber reinforced polymer vessels and/or components that have been subjected to acoustic emission evaluation at elevated temperature has resulted...

... ) . This causes increased cost due to the need for a boiler. Safety is also a concern due to the possibility of a leak or failure of the vessel during testing. More important than these two items is the lack of data that is available from fiber reinforced polymer (FRP) vessels and/or components that have been...

... of interest, it may be concluded that the vessel will not tolerate this level of stress during repeated use. The design of fiber reinforced polymer tanks and pressure vessels is typically governed by one of two codes, the American Society of Mechanical Engineers RTP-1 Standard (Reinforced Thermoset...
