CR4 - Thread: API 5L Minimum Temperature

cr4.globalspec› Mechanical EngineeringJul 19, 2013· I've been told that the minimum temperature of API 5L material according to the pipeline codes (ASME B31.4 and B31.8) is 32F. In ASME B31.3, the minimum temperature of API 5L is -20F according to the stress tables in the back.

CVN Test Temperature for API 5L B31.4 pipe - Pipelines ...

eng-tips› Forums› Mechanical Engineers› ActivitiesAug 13, 2012· The standard API Spec 5L Charpy test temperature is 0 deg C. The minimum design temperature should be set by process and mechanical engineers and need not be below 0 deg C to incur Charpy testing. ... The need for impact testing is not based on the lowest ambient temperature conditions. The temperature is based on the minimum metal temperature ...The standard API Spec 5L Charpy test temperature is 0 deg C. The minimum design temperature should be set by process and mechanical engineers and need not be below 0 deg C to incur Charpy testing. Steve Jones Materials & Corrosion Engineer linkedin/pub/8/83b/b04So if the project is in an area of the country where the lowest one-day mean temperature is -15 degrees it is still OK to do the CVN at +32? Can you help me understand the rational? For instance for above ground storage tanks the CVN temperature is the design metal temperature which is based on the lowest one-day mean temperature.I understand that for the underground portion, the pipe will never see temperatures low enough to be of concern and the same could be said for above ground portions that are normally full but what about the pig traps that are empty possibly for long periods and then get sudden pressure? If they cooled off to ambient ( say -20 ) is there a concern that they may fail when the pig and pressure come?Setting the Charpy test temperature against the minimum design temperature is another question. At first sight, given the quoted environmental conditions, a minimum design temperature of 0 deg C does seem inappropriate. B31.4 stipulates the Charpy test temperature relative to the lowest expected metal temperature and API Spec 5L states that other Charpy test temperatures can be agreed. Steve Jones Materials & Corrosion Engineer linkedin/pub/8/83b/b04And therein lies the problem. Neither of the codes gives guidance on determining the CVT temperature if different than 0 deg C. The 49 CFR 195 paragraph 102 is similarly silent. I'm wondering if the materials that are generally used are sufficiently resistant to brittle fracture that for the continental USA there is no need to change from 0 deg C. Perhaps the industry simply does not need to be worried about this and I am barking up the wrong tree.The need for impact testing is not based on the lowest ambient temperature conditions. The temperature is based on the minimum metal temperature at a design load. If the pig launchers/receivers are envisioned to (designed) and will operate at -20 F at a pressure of 72% of the base materials' SMYS, it behoves you to purchase the base materials impact tested at -20 F or below. If this is not the case, or the design condition is low; e.g., < 50% of the SMYS at -20F, there is really no need to do so if the longitudinal welds are suitably examined. This is an Engineering decision.B31.4 (2009, 24 Mar 2010) Charpter III Materials 423.2.3 Steel "The test temperature shall be the lower of (32F-0C) or the [b]LOWEST expected metal temperature [b]during service , having regard to past recorded temperature data and possible effects of lower air and ground temperatures."
