摘要： A method of determining a carburisation model of a coil of a steam cracking furnace, the method comprises the steps of: determining reference temperature values at reference positions of a wall of a reference coil during operation of a reference steam cracking furnace comprising a reference coil; determining reference carburised portion values of a depth at a reference point in time; determining the at least one material specific constant in dependence of the first relation and the second relation; and determining the carburisation model of the coil in dependence of the determined at least one material specific constant and further in dependence of the first relation and the second relation.

摘要： Provided is a method of connecting an austenitic steel pipe with a ferritic steel pipe. The method comprises providing the austenitic steel pipe and the ferritic steel pipe, such that an inner end section of the austenitic steel pipe has an outer diameter smaller than an inner diameter of an outer section of the ferritic steel pipe, inserting the inner end section into the outer end section, such that the inner and outer end sections overlap in a connection region, and welding the inner and outer end sections in the connection region by explosive welding or magnetic pulse welding. Further, a linear quench exchanger and a processing arrangement for processing a process fluid are provided.

摘要： Provided is a connection element comprising a tubular first part with a first ring-shaped connection face for connection with a highly heat resistant steel pipe and a tubular second part with a second ring-shaped connection face for connection with a first ferritic steel pipe; wherein the first part is of a corrosion resistant steel material and wherein the second part is of a ferritic steel material; wherein the first and second parts are in one-piece and formed such that a passage between the first and second ring-shaped connection faces is formed; and wherein the first and second parts are produced by an additive manufacturing process. Further provided are a pipe arrangement and a heat exchanger.
