As a result, hardening (and embrittlement) of the metal can occur to varying degrees (usually dependent on carbon content). Heat treatment is designed to reduce the hardness in the heat-affected zone of the metals and increase ductility in these sections. Various pressure vessel codes contain the specifics regarding the procedures for post-weld heat treatment. Heat is usually held for one hour per inch of thickness of the metal. The temperature used is based on the "P-number" of the metals. P-numbers are assigned based on the chemical composition of the metals. Holding temperatures can range from 1100-1350 °F (593-732 °C). http://www.coolinterview.com/interview/36990/ What chemical is used to expand air bags in such a short amount of time? http://www.coolinterview.com/interview/36979/ Explain global warming from a common man's and an engineer's perspective. http://www.coolinterview.com/interview/36927/ What type of flow measurement devices is best for slurries? http://www.coolinterview.com/interview/37052/ What is the best way to configure a bypass line in slurry services? http://www.coolinterview.com/interview/37050/ What are PCB's? http://www.coolinterview.com/interview/36967/ How can I evaluate the thermal relief requirements for double block-in of 98% sulfuric acid? http://www.coolinterview.com/interview/37021/ Should slurry pipes be sloped during horizontal runs? http://www.coolinterview.com/interview/37051/ How can a chemical production engineer improve the process with respect to yield & quality? http://www.coolinterview.com/interview/36915/ Who built the first production scale PLA (polylactic acid) facility? http://www.coolinterview.com/interview/36959/ What steps can be taken to avoid stress corrosion cracking (SCC) in steel vessels used for storing anhydrous ammonia? http://www.coolinterview.com/interview/36980/ List the advantages and disadvantages of a PFR. http://www.coolinterview.com/interview/36923/ What information is needed to specify a mixer? http://www.coolinterview.com/interview/37005/ What factors go into designing the vapor space of kettle type reboiler? http://www.coolinterview.com/interview/37068/ What are some factors to consider when trying choosing between a dry screw compressor and an oil-flooded screw compressor? http://www.coolinterview.com/interview/37057/ What are some characteristics of bulk solids that can affect their ability to flow properly? http://www.coolinterview.com/interview/36955/ What is the Wet Bulb Globe Temperature (WBGT)? http://www.coolinterview.com/interview/36970/ What type of pump may be appropriate for a liquid near saturation, a low flow rate, and very limited NPSHa (net positive suction head available)? http://www.coolinterview.com/interview/37053/ What types of metals are typically removed via chemical precipitation? http://www.coolinterview.com/interview/36973/ What are the three classes of organic solvents? http://www.coolinterview.com/interview/36964/ What is quicklime and what are the uses? http://www.coolinterview.com/interview/36966/
