ABSTRACT:
This invention relates to an improved transfer line exchanger inlet cone for connecting the process gas outlet of a hydrocarbon cracking heater with the inlet of a transfer line heat exchanger, and to methods of making the same. Stress cracking and high temperature failures of the inlet cone are eliminated without affecting the flow pattern of the process gas.
